Web scraping is the process of amassing structured web data in an automated fashion. It’s additionally called web data extraction. Some of the primary use cases of web scraping include price monitoring, price intelligence, news monitoring, lead generation, and market research amongst many others.

The basics of web scraping

It’s very simple, in truth, and works by way of parts: a web crawler and a web scraper. The web crawler is the horse, and the scraper is the chariot.

The crawler

In many projects, you first “crawl” the web or one particular website to discover URLs which then you definitely pass on to your scraper.

The scraper

A web scraper is a specialized instrument designed to accurately and quickly extract data from a web page. Web scrapers range widely in design and complexity, relying on the project. An important part of every scraper is the data locators (or selectors) that are used to seek out the data that you want to extract from the HTML file – often, XPath, CSS selectors, regex, or a mix of them is applied.

The web data scraping process

If you do it yourself

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

Identify the goal website

Accumulate URLs of the pages the place 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 in the HTML

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

Simple sufficient, proper? It’s! In the event you just have a small project. But unfortunately, there are quite a number of challenges you must tackle for those who need data at scale. For example, sustaining the scraper if the website structure modifications, managing proxies, executing javascript, or working around antibots.
