Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites. Usually, such software programs simulate human exploration of the World Wide Web by either implementing low-level Hypertext Transfer Protocol (HTTP), or embedding a fully-fledged web browser, such as Internet Explorer or Mozilla Firefox.

Web scraping is closely related to web indexing, which indexes information on the web using a bot or web crawler and is a universal technique adopted by most search engines. In contrast, web scraping focuses more on the transformation of unstructured data on the web, typically in HTML format, into structured data that can be stored and analyzed in a central local database or spreadsheet. Web scraping is also related to web automation, which simulates human browsing using computer software. Uses of web scraping include online price comparison, contact scraping, weather data monitoring, website change detection, research, web mashup and web data integration.

Techniques

Web scraping is the process of automatically collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions. Current web scraping solutions range from the ad-hoc, requiring human effort, to fully automated systems that are able to convert entire web sites into structured information, with limitations.

1.
Human copy-and-paste: Sometimes even the best web-scraping technology cannot replace a human’s manual examination and copy-and-paste, and sometimes this may be the only workable solution when the websites for scraping explicitly set up barriers to prevent machine automation.

2.
Text grepping and regular expression matching: A simple yet powerful approach to extract information from web pages can be based on the UNIX grep command or regular expression-matching facilities of programming languages (for instance Perl or Python).

3.
HTTP programming: Static and dynamic web pages can be retrieved by posting HTTP requests to the remote web server using socket programming.

4.
HTML parsers: Many websites have large collections of pages generated dynamically from an underlying structured source like a database. Data of the same category are typically encoded into similar pages by a common script or template. In data mining, a program that detects such templates in a particular information source, extracts its content and translates it into a relational form, is called a wrapper. Wrapper generation algorithms assume that input pages of a wrapper induction system conform to a common template and that they can be easily identified in terms of a URL common scheme. Moreover, some semi-structured data query languages, such as XQuery and the HTQL, can be used to parse HTML pages and to retrieve and transform page content.

5.
DOM parsing: By embedding a full-fledged web browser, such as the Internet Explorer or the Mozilla browser control, programs can retrieve the dynamic content generated by client-side scripts. These browser controls also parse web pages into a DOM tree, based on which programs can retrieve parts of the pages.

6.
Web-scraping software: There are many software tools available that can be used to customize web-scraping solutions. This software may attempt to automatically recognize the data structure of a page or provide a recording interface that removes the necessity to manually write web-scraping code, or some scripting functions that can be used to extract and transform content, and database interfaces that can store the scraped data in local databases.

7.
Vertical aggregation platforms: There are several companies that have developed vertical specific harvesting platforms. These platforms create and monitor a multitude of “bots” for specific verticals with no "man in the loop" (no direct human involvement), and no work related to a specific target site. The preparation involves establishing the knowledge base for the entire vertical and then the platform creates the bots automatically. The platform's robustness is measured by the quality of the information it retrieves (usually number of fields) and its scalability (how quick it can scale up to hundreds or thousands of sites). This scalability is mostly used to target the Long Tail of sites that common aggregators find complicated or too labor-intensive to harvest content from.

8.
Semantic annotation recognizing: The pages being scraped may embrace metadata or semantic markups and annotations, which can be used to locate specific data snippets. If the annotations are embedded in the pages, as Microformat does, this technique can be viewed as a special case of DOM parsing. In another case, the annotations, organized into a semantic layer, are stored and managed separately from the web pages, so the scrapers can retrieve data schema and instructions from this layer before scraping the pages.

9.
Computer vision web-page analyzers: There are efforts using machine learning and computer vision that attempt to identify and extract information from web pages by interpreting pages visually as a human being might

Scrape Data from Website is a Proven Way to Boost Business Profits

Scrape Data from Website is a Proven Way to Boost Business Profits

Data scraping is not a new technology in market. Several business persons use this method to get benefited from it and to make good fortune. It is the procedure of gathering worthwhile data that has been located in the public domain of the internet and keeping it in records or databases for future usage in innumerable applications.

There is a large amount of data available only through websites. However, as many people have found out, trying to copy data into a usable database or spreadsheet directly out of a website can be a tiring process. Manual copying and pasting of data from web pages is shear wastage of time and effort. To make this task easier there are a number of companies that offer commercial applications specifically intended to scrape data from website. They are proficient of navigating the web, evaluating the contents of a site, and then dragging data points and placing them into an organized, operational databank or worksheet.

Every day, there are numerous websites that are hosting in internet. It is almost impossible to see all the websites in a single day. With this scraping tool, companies are able to view all the web pages in internet. If a business is using an extensive collection of applications, these scraping tools prove to be very useful.

It is most often done either to interface to a legacy system which has no other mechanism which is compatible with current hardware, or to interface to a third-party system which does not provide a more convenient API. In the second case, the operator of the third-party system will often see screen scraping as unwanted, due to reasons such as increased system load, the loss of advertisement revenue, or the loss of control of the information content.

Scrape data from website greatly helps in determining the modern market trends, customer behavior and the future trends and gathers relevant data that is immensely desirable for the business or personal use.

13 Ways to Use Web Scraping Tools

Consider the amount of raw data floating around the internet: webpages made up of text, images, videos, graphics, memes, infographics, and more. It’s mind-boggling when you slow down and think about it.

The latest estimate puts the total number of websites at roughly one billion, with new ones added and old ones disappearing all the time. Each second, there are approximately 7548 tweets, 772 Instagram photos posted, 2,573,338 emails sent, and 42,943GB of internet traffic… to name just a few.

According to Cisco, global internet traffic hit 1.1 zettabytes per year (a zettabyte is one sextillion bytes, or the same as 36,000 years of HD video) at the end of 2016, and will cross the 2.3 zettabytes threshold by 2020.

Overall, the internet has nearly doubled in size every year since 2012.

So, yes. It’s big. And there’s a lot of data.

That data can be harnessed to help with a wide variety of things if you know how to do it. You could navigate from site to site, from page to page, picking and choosing the details you need for whatever it is you’re doing, and copying the relevant information to another file or spreadsheet before moving on to the next website, page, or paragraph.

That’s Option A, or what we might call the “Classic Method” (classic because you really had no choice) – slow, laborious, and tedious.

Option B?

Let’s dig a little deeper into the art of web scraping.

Web Scraping


Also known as web harvesting, data mining, screen scraping, and (web) data extraction, web scraping is the removal of large amounts of data from a website, which is then saved to a local file on a computer, database, or spreadsheet.

It automates the process of copying and pasting selected sections of a page or an entire website to be reviewed and analyzed later from one convenient place.

Web scraping tools first fetch – download the page for viewing like a web browser does – and then extract the chosen data – which may be copied, parsed, searched, and reformatted. Many tools allow you to collect data from hundreds or thousands of URLs at the same time (or in scheduled sequence).

Basically, any data that can be viewed online – even behind a login wall (provided you have the proper credentials) – can be scraped.

“But why?” you might well ask. What’s the big deal, and what are some of the things you can do with the scraped data?



They say that knowledge is power, and in 2017, knowledge comes increasingly in the form of digital data sets. The more you have, the better your decisions, plans, tactics, strategies, and success.

So how can you use data scraping tools? Here are just a few of the ways.

In Your Marketing Efforts


It doesn’t matter what you’re selling, whether it’s a product or a service, whether it’s something everyone could use or designed for a very small and exclusive niche; if you want to succeed and grow your business, you need to market.

And in 2017 and beyond, that means promoting online and working with digital data. According to Hubspot’s annual State of Inbound report, 65% of marketers say generating traffic and leads is their biggest challenge.

Web scraping can help with both. Let’s look at the traffic issue first.

1. Search Engine Optimization
Traffic coming to a website can arrive from a variety of channels, including direct, paid, social, email, and referral.

For many, though, it’s organic search – traffic originating from a search engine inquiry – that serves up the biggest slice of the pie. And as luck would have it, this traffic often tends to be the most relevant and highest converting (because they went looking for something you have or know).

There are several ways you can boost your organic search traffic, but they all ultimately have to do with your search engine optimization (SEO).

Enter web scraping. With it, you can scrape SERPs for SEO management, and take your SEO analysis up a notch (or two).

First, you can track your page ranks over time by scraping the various search engine result pages for your given keyword or query.

You can immediately see where you rank for each targeted keyword, as well as whether you’re moving up (so should continue doing whatever you’re doing), down (and should change course), or staying the same (you need to do something) over time, and whether some keywords should be abandoned because the top five or ten results are made up of virtually unbeatable websites (think Amazon, Apple, Walmart, and so on).

You need to rank high. Results 1-4 get around 83% of the clicks, leaving a paltry 17% for every other result.

Second, you can turn to your direct competition and see what keywords and phrases they’re ranking for and targeting. You might find some that you hadn’t even considered. A thorough scrape and text analysis of their site content will reveal their keyword list and strategies. If they’re generally ranking higher than you, consider switching to a few of theirs.

A scraped content data set can give you insight into the titles, keywords and their densities, descriptions, link counts, and visual elements that are working for them… because they’ll likely work for you, too.



2. Market Research
Any good business owner knows that market research is part of their due diligence when launching, expanding, or changing.

Opportunities. Threats. Trends. Predictions. Collect, organize, and analyze it all.

Classic & Sports Finance – a leading classic and race car finance company – uses scraped auction, sales, and dealer pricing data to keep abreast of market trends and real-time competitive pricing structures. Web scraping is integral to its business model and success.

A web scraper can extract the necessary data from analytics providers, market research firms, directories, industry blogs or news sites, and collect everything in a single spot. It takes market research from time-consuming and frustrating to quick and simple.

With it, for example, you can organize an extensive list of the direct and indirect competition, or the potential customer base (based on your buyer personas) in a given area, and more.

Speaking of which…

3. Lead Generation
Depending on your business, a lead may be simply a name and contact details for an individual (that hopefully fits your buyer persona). There are many tactics and tools you can try to generate them. Social media, answering questions on Quora, speaking events, conferences, guest posting, paid ads, lead magnets…

And – you guessed it – web scraping. How?

At its most basic, you’re just looking for contact info that fits a profile. If you have a new cloud accounting SaaS that caters to dentists, you need a list of dentists. If you have a car seat design that’s safer than traditional ones, you need a list of parents with young children.

A scraper can collect the necessary details – names, email addresses, URLs, phone numbers – in a process that’s often called contact scraping. Your dentist SaaS? A state directory of licensed dentists would provide you with a long list of quality leads. Your improved car seat? Try the parent directory at some local schools and day care centers.

All the information you need is available online if you know where to look. Just Google “[blank] directory/association/index/register/club/guild/organization/union” and anything else that would narrow your search down, such as “dentist directory minnesota” or “PTA contact list Lo-Ellen Park High School.”

Another good source is a review site like Yelp.

You can further qualify those leads by searching or filtering the data by keywords, demographics, or any other criteria to find your exact buyer personas.

So it’s not just leads, it’s qualified leads. That’s a goldmine.

Soap bubble entertainment company Bubbly uses web scraping to monitor its competition and market, but also to generate leads and keep a steady flow of prospects heading into its sales funnel.

With contact details available on the web, Bubbly can build its customer base, make the necessary adjustments to its supply chain as demand dictates, and ultimately grow its business without the stress or hassle of having to track down leads on a one-by-one basis.

In Your Competitor Analysis


Any savvy business owner recognizes the importance of keeping an eye on the competition.

What are they doing in their marketing, what content are they pushing, what keywords and phrases are ranking for them (which we already discussed above), what pricing structure are they using, and what’s the general opinion of them from consumers? These are just a few of the questions you should be asking.

To get the answers, you can once again turn to your trusty web scraping tool.

4. Reviews and Sentiment
Scrape from Yelp, Zomato, TripAdvisor, the Better Business Bureau, Trustpilot, Google, Amazon, or some other business review site to see customer reviews and comments about them (and you).

Turn to social media platforms and search by brand or product names to get additional data, and perhaps even leverage sentiment analysis to learn how people feel about certain businesses and products.

Scrape business profiles and corresponding reviews for insight and assistance with reputation management. Profit from the competition’s weaknesses and complaints (offer a better solution), and address your own.

5. Content Approach and Followers
A competitor’s blog and social media accounts are a great place to analyze their content marketing (perhaps opening the door for you to use the skyscraper technique and build off their foundation), as well as to see who has followed or liked them (maybe giving you the opportunity to contact those followers and offer an incentive to make the switch).

6. Price Comparison
You might also scrape for the purposes of price comparison and tracking. What are competitors charging – and what have they charged over time – for the same or similar product? Consumers like to see comparisons between Brand A and Brand B. In fact, 51% of successful campaigns include a comparison or ranking.

Your pricing can obviously make or break you. You need to be competitive. Give it every advantage possible.

Three major grocery store chains – Tesco, Waitrose, and Sainsbury – all use web scraping as part of their pricing strategy. Every morning, they scrape 33 items in the Consumer Price Index food basket, and compare those prices against other items that match the description (so apples in the CPI basket would include granny smith, red delicious, and so forth). The scraper extracts an average of 5000 quotes related to the 33 items each day, or about 150,000 per month.

This allows them to stay competitive and within acceptable pricing standards without having to send someone to manually collect price data points, which used to be standard in the industry.

7. Change Detection
Finally, a good scraper can be set up to detect and scrape website changes. You can keep your finger on the pulse of your competition and know immediately when they have a new product, lower their prices, begin a special promotion, publish a new blog post, or anything else.

With that kind of data at your fingertips, you can react, adjust, and respond quickly and appropriately.

In Your Professional and Personal Life


Web scraping is obviously a valuable business exercise, but it’s not limited to just your professional activities. It can simplify and save you time in your personal life, too.

Web scraping works equally well for business or private purposes.

8. Job Hunting and Recruiting
Looking for a new job? Try scraping dozens or hundreds of the top job portals, sites, and forums. Include social media (search by company or keyword), digital bulletin boards, and classified listings.

Looking to fill a position at your company? Turn to many of the same sources, and filter results with the precise criteria you want and need in an applicant. Scrape a college or university graduating senior student directory in a related field of study.

9. Products and Services
Everyone buys products and services of their own.

As a customer, you can copy and aggregate several directories of services (dentist, lawyer, plumber, contractor) or product providers that you need. Compare reviews, prices, and more to find the best fit at the best price.

Compile a list of used cars that match your requirements from several different sites. Or school options for your kids in a new city. Or anything else that fits a set of criteria you create.

Choosing your next smartphone, for example, can be a major headache because of the massive number of choices: iPhone, BlackBerry, Windows Mobile, or the dozens of Android options.

The website Unmudlr uses web scraping to make it super easy for you by asking a few basic questions. It then uses its vast array of scraped data – including detailed descriptions and pricing information – to present the phones that meet your specific requirements.

10. Research
Academic. Professional. Into every life, a little research must fall. Make it quick and painless with web scraping.

Collect info and data sets about any subject from hundreds or thousands of different sources. With billions of articles, case studies, and web pages to choose from, you can expand the scope of your research while you refine your search and save time and money while doing it.

11. Financial Planning
Maybe you have an investment planner, and maybe you don’t. Either way, it’s wise to have an understanding of what’s going on, and to be able to at least provide some input when it comes to decisions about your money.

Scrape data on stocks and bonds (performance over time, expert analysis and predictions), investment properties (rental prices at similar places at or near your location, neighborhood reviews and sentiment), and the companies you or your planner are interested in (sentiment analysis, reviews, industry expectations).

Will it make you a guaranteed million? No. But an informed decision is a better decision. Collect the details you need to get and stay informed.

12. Looking to Buy or Rent
To give you an example of web scraping in a specific industry, consider real estate. The opportunities for a scraping tool to improve the experience of an agent or buyer are many.

As a house hunter, you could create a complete data set of all options available to you from multiple agents and listings, aggregate details in a single location, and fill in the gaps to give you a more complete picture of a particular property, neighborhood, or agent.

13. Looking to Sell
As a real estate agent, you can collect data points on neighborhoods, cities, personal stories, and images to create powerful property listings. You can scour house-for-sale and seeking-house classifieds, contacting buyers, sellers, and renters to offer your services and make their job easier.

As a home or property owner looking to sell or rent out the place, you can scrape similar listings to see the language and key points of interest that others are choosing to highlight. What keywords are they using in the description? Which points of interest do they include for the area?

These are just some of the ways you could use a scraping tool to simplify, enhance, and boost what you’re doing at work and at home.

Data Extraction Product vs Web Scraping Service which is best?

Product v/s Service: Which one is the real deal?

With analytics and especially market analytics gaining importance through the years, premier institutions in India have started

offering market analytics as a certified course. Quite obviously, the global business market has a huge appetite for information

analytics and big data.

While there may be a plethora of agents offering data extraction and management services, the industry is struggling to go

beyond superficial and generic data-dump creation services. Enterprises today need more intelligent and insightful information.

The main concern with product-based models would be their incapability to extract and generate flexible and customizable data

in terms of format. This shortcoming can be majorly attributed to the almost-mechanical process of the product- it works only

within the limits and scope of the algorithm.

To place things into perspective, imagine you run an apparel enterprise. You receive two kinds of data files. One contains data

about everything related to fashion- fashion magazines, famous fashion models, make-up brand searches, apparel brands

trending and so on. On the other hand, the data is well segregated into trending apparel searches, apparel competitor strategies,

fashion statements and so on. Which one would you prefer? Obviously, the second one- this is more relevant to you and will

actually make life easier while drawing insights and taking strategic calls.


In the scenario where an enterprise wishes to cut down on overhead expenses and resources to clean the data and process it into

meaningful information, that’s when the heads turn towards service-based web extraction. The service-based model of web

extraction has customization and ready-to-consume data as its key distinction feature.

Web extraction, in process parlance is a service that dives deep into the world of internet and fishes out the most relevant data

and activities. Imagine a junkyard being thoroughly excavated and carefully scraped to find you the exact nuts, bolts and spares

you need to build the best mechanical project. This is metaphorically what web extraction offers as a service.

The entire excavation process is objective and algorithmically driven. The process is carried out with a final motive of extracting

meaningful data and processing it into insightful information. Though the algorithmic process leads to a major drawback of

duplication, unlike a web extractor (product), wweb extraction as a service entails a de-duplication process to ensure that you are

not loaded with redundant and junk data.

Of the most crucial factors, successive crawling is often ignored. Successive crawling refers to crawling certain web pages

repetitively to fetch data. What makes this such a big deal? Unwelcomed successive crawling can lead to attracting the wrath of

the site owners and the high probability of being sued for a class action suit.

While this is a very crucial concern with web scraping products , web extraction as a service takes care of all the internet ethics

and code of conduct while respecting the politeness policies of web pages and permissible penetration depth limits.

Botscraper ensures that if a process is to be done, it might as well be done in a very legal and ethical manner. Botscraper uses

world class technology to ensure that all web extraction processes are conducted with maximum efficacy while playing by the

rules.

An important feature of the service model of web extraction is its capability to deal with complex site structures and focused

extraction from multiple platforms. Web scraping as a service requires adhering to various fine-tuning processes. This is exactly

what botscraper offers along with a highly competitive price structure and a high class of data quality.

While many product-based models tend to overlook the legal aspects of web extraction, data extraction from the web as a service

covers it much more ingeniously. While associating with botscraper as web scraping service provider, legal problems should be

the least of your worries.

Botscraper as a company and technology ensures that all politeness protocol, penetration limits, robots.txt and even the informal

code of ethics is considered while extracting the most relevant data with high efficiency.  Plagiarism and copyright concerns are

dealt with utmost care and diligence at Botscraper.

The key takeaway would be that, product-based web extraction models may look appealing from a cost perspective- that too only

at the face of it, but web extraction as a service is what will fetch maximum value to your analytical needs. Ranging right from

flexibility, customization to legal coverage, web extraction services score above web extraction product and among the web

extraction service provider fraternity, botscraper is definitely the preferred choice.
