Web crawlers allow you to collect data from websites and use it to make vital decisions. In this article, we will explore everything you need to know about web crawlers.
Web crawlers are tools used by search engines to search for information on websites based on the keywords given. Also known as a spider bot, website spider, a crawling agent, or web crawling agent, a web crawler is also used by search engines to collect website data like URLs, meta tags, hyperlinks, and more.
This tool then crawls them and this becomes an endless process. However, to prevent visiting the same sites severally, the bot keeps track of the web pages that it has already accessed.
As aforementioned, a web crawler is mostly used by search engines to index websites and gather data according to the keywords you have entered.
Nevertheless, a web crawler is also useful for companies that need to gather relevant data that will help them make informed decisions. They can also use these tools to identify the most gainful keywords from search engines that they can use to drive performance.

The issue of web crawling vs web scraping has been lingering in most people’s minds. In most cases, web crawling is often mistaken for web scraping and these words are sometimes used interchangeably. However, these two are very different.
Web crawling is the technique of gathering data from websites while web scraping is the technique of extracting data and duplicating data in the form or slightly modified form of the content from the page it accesses.
Basically, web crawling only checks pages and content and only deals with metadata that is not made visible to the user. On the other hand, web scraping extracts and collects tangible content from web pages and delivers it to you.
Unlike popular belief, web scraping and web crawling do not work simultaneously. However, they can work together, whereas the web crawler crawls the pages and generates a link list and then the web scraper scrapes the pages with the most valuable data.
So, when it comes to web crawling vs web scraping, combining the two tools helps to automate the process of collecting and processing data without any human labor. To dig deeper into the topic, read this web crawling vs web scraping article.

They can then use the scraping tools to extract the pricing data from various suppliers, so they don’t miss out on the best deals.
Other than analyzing the pricing, companies can also take advantage of web crawlers to keep up to date with their own brands. The web crawler can help you find information and mentions about your company in the online space like in social media posts and news articles.
