Web scraping is the process of accumulating structured web data in an automatic fashion. It’s also called web data extraction. A number of the main use cases of web scraping include value monitoring, value intelligence, news monitoring, lead generation, and market research amongst many others.

Generally, web data extraction is utilized by individuals and businesses who wish to make use of the vast amount of publicly available web data to make smarter decisions.

If you happen to’ve ever copy and pasted information from a website, you’ve performed the same operate as any web scraper, only on a microscopic, handbook scale.

Web scraping is popular

The basics of web scraping

It’s very simple, in reality, 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. Learn the difference 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 material by following links and exploring, like a person with an excessive amount of time on their hands. In lots of projects, you first “crawl” the web or one particular website to discover URLs which then you pass on to your scraper.

The scraper

A web scraper is a specialized device designed to accurately and quickly extract data from a web page. Web scrapers vary widely in design and complexity, depending on the project. An necessary part of each scraper is the data locators (or selectors) which might be used to find the data that you want to extract from the HTML file – usually, XPath, CSS selectors, regex, or a mix of them is applied.

The web data scraping process

For those who do it yourself

This is what a basic DIY web scraping process looks like:

Identify the target website

Collect URLs of the pages where you want to extract data from

Make a request to those URLs to get the HTML of the web page

Use locators to search out the data within the HTML

Save the data in a JSON or CSV file or another structured format

Simple sufficient, right? It’s! In the event you just have a small project. However unfortunately, there are quite a number of challenges you have to tackle should you need data at scale. For example, maintaining the scraper if the website format modifications, managing proxies, executing javascript, or working around antibots. These are all deeply technical problems that may eat up a number of resources. That’s part of the reason many companies choose to outsource their web data projects.
