Difference Between Web Scraping & Web Crawling

Web scraping is the process of parsing websites for information, or data. If you know how to use a web browser, then you can extract information from websites using a web browser. However, there are many websites that don’t provide information that is easily available in the same format for everyone to see. Web crawlers are programs that crawl the web, then extract information from websites. This information could be anything from a single page, to all of the information on a website or even all of the server logs. Web crawlers are used for many purposes such as malware analysis, electronic voting, or search engine optimization.

Web Scraping & Web Crawling are two different technologies used to extract, store and analyze data from the data sources and web pages. Scraping is the process of extracting data from a website. This data can be stored in an internal database or be converted to a specific format and then stored in a structured format. Web Crawling is the process of accessing a website to perform a specific task such as search engine optimization, retrieval of data or conversion of data to a specific format.

Every company and individual on this planet is constantly trying to improve their products, services, and/or business. In order to do so, they need your information. But how do companies get that information? And how do they keep it safe? Web Scraping is the process of extracting information from a website, usually by using a script to parse the content, and crawling the web site. Crawling is the process of following a given hyperlink or URL, and retrieving any documents that are discovered along the way.

Web crawling and web scraping are two commonly used terms. They look the same, but what do they mean? There is a subtle difference between web crawling and web scraping. The two concepts are related, but have many variations.

When you work online, there’s usually a lot going on behind the scenes. Various companies collect, harvest and aggregate data. Search engines, on the other hand, strive to make searching easy, relevant and fast by optimizing content.

Crawlers or bots are used to continuously crawl different pages to provide relevant data, key index information and cache data to ensure the best user experience. That’s what crawling is all about. The purpose of the removal is to extract certain information. Robots or bots are needed for this process.

In most cases, the terms scraping and crawling are used interchangeably. One can assume that web scraping is a much more targeted process. Scraping generates specific data for further processing. This makes scraping an ideal solution for those who want to extract data from a specific source and use it in innovative and unexpected ways.

Scratching and crawling can be used to perform various activities. Both can be z. For example, used to mimic human behavior, connect to a website, execute JavaScript, etc.

Simply put, crawling is the process of collecting and retrieving hyperlinks for indexing purposes. Web scraping, on the other hand, is the automated process of querying a web document and gathering information from it. Oxylabs is a good example of a tool that can manage both scraping and crowling. But let’s take a closer look at scraping and crowing.

Scrapping and Crawling | Web Crawling

A web crawler is a separate program (web spider) that visits websites and consults their pages and information to create various entries for a search engine’s index. Crawlers collect and find web links from initial URLs. They surf through the site, find new pages, click on various links and haphazardly extract data. The exploration of the web is the fuel for the various search engines available.

Scraping and Crowling | Web Scraping

Web scraping is the process of obtaining structured information from a web page. In most cases, this process is performed with tools specifically designed for the target website. Did you know you can scrub without crawling? That’s right; you can scrape without having to crawl, especially if you have a list of URLs you want to scrape.

Scraping focuses on structured data, such as. For example, a scraper designed to collect email addresses, names, phone numbers, price comparisons and URLs of companies. Once this information is received, it can be searched, formatted, analyzed and copied into the database.

Scraping and crawling Differences

There are several differences between a crawler and a scraper. Let’s look at the main differences to get the big picture.

  • Crows is too common compared to specifically crows
  • The scraper takes over and loads the selected data… it just requests the data. On the other hand, the crawler will traverse the selected targets without crawling.
  • Scraping can be done manually, while crawling must be done with the help of a crawling agent or a spider robot.
  • In the case of web scraping, deduplication is performed on a smaller scale and deduplication is not always necessary as it can be done manually. Web browsing allows you to duplicate a large amount of information on the Internet. To avoid collecting too much duplicate content, the crawler will always filter this kind of content.

Use of web scraping

Our world is flooded with information, and experts are still looking for ways to harness it. Therefore, scraping has become very popular in recent years for processing massive and aggregated data sets. This capability has proven useful in the areas of eCommerce, Big Data, machine learning, analytics and artificial intelligence.

Here are some of the most common uses of web scraping.

  • Price Comparison – Companies that want to perform in-depth data analysis for a specific application use scrapers. Once they have this information, they use it to compare prices in different places and markets.
  • Brand Protection – Staples is used in this case to protect brands by overseeing the proper use of their insignia, trademarks and intellectual content.
  • Research – Data mining is used for academic, scientific, marketing research, etc.

It should be noted that proxy servers can be used in scraping to obtain different IP addresses for scraping from random geolocations without restrictions.


Based on the above content, you can see the differences between web scraping and crawling. Crawler actually crawls like a spider through various targets on the Internet. Once it reaches its destination, it is deleted. This means that the target data is collected and downloaded.Web scraping is the act of pulling data from a website by using scripts. Web crawling is the act of sending requests to a website to collect data. Web scraping is usually done by specialized web crawlers that send a request to a website in order to collect the data. Web crawlers can be written by experts in web programming and can be a huge help in extracting the data. Web crawling can also be done by web spiders that send a request to a website and collect the data from the website. Web crawlers and web spiders are two separate ways of extracting data from a website..
