Web scraping is the process of accumulating structured web data in an automated fashion. It’s also called web data extraction. A number of the predominant use cases of web scraping embrace value monitoring, price intelligence, news monitoring, lead generation, and market research amongst many others.
Usually, web data extraction is utilized by individuals and businesses who need to make use of the huge amount of publicly available web data to make smarter decisions.
When you’ve ever copy and pasted info from a website, you’ve carried out the identical function as any web scraper, only on a microscopic, guide scale.

Web scraping is standard
And it shouldn't be surprising because web scraping provides something really valuable that nothing else can: it gives you structured web data from any public website.
More than a modern comfort, the true power of data web scraping lies in its ability to build and energy a few of the world’s most revolutionary enterprise applications. ‘Transformative’ doesn’t even start to describe the way some corporations use web scraped data to enhance their operations, informing executive decisions all of the way down to individual customer service experiences.
The fundamentals of web scraping
It’s very simple, in fact, and works by way of two parts: a web crawler and a web scraper. The web crawler is the horse, and the scraper is the chariot. The crawler leads the scraper, as if by hand, by means of the internet, the place it extracts the data requested. Study the distinction between web crawling & web scraping and the way they work.
The crawler
A web crawler, which we generally call a "spider," is an artificial intelligence that browses the internet to index and seek for content by following links and exploring, like an individual with an excessive amount of time on their hands. In many projects, you first "crawl" the web or one particular website to discover URLs which you then pass on to your scraper.
The scraper
A web scraper is a specialised device designed to accurately and quickly extract data from a web page. Web scrapers differ widely in design and complexity, depending on the project. An important part of each scraper is the data locators (or selectors) which can be used to search out the data that you need to extract from the HTML file - normally, XPath, CSS selectors, regex, or a mixture of them is applied.
The web data scraping process
Should you do it yourself
This is what a general DIY web scraping process looks like:
Determine the target website
Gather URLs of the pages where you want to extract data from
Make a request to these URLs to get the HTML of the web page
Use locators to search out the data in the HTML
Save the data in a JSON or CSV file or some other structured format
Simple enough, right? It is! When you just have a small project. But unfortunately, there are quite a couple of challenges you should tackle if you want data at scale. For example, sustaining the scraper if the website structure adjustments, managing proxies, executing javascript, or working around antibots. These are all deeply technical problems that can eat up a lot of resources. That’s part of the reason many companies choose to outsource their web data projects.
