What is web crawling?

We can say that web crawling is the Google bot software. When we update anything on the website, then it will crawl the website and collect the data and send it to Google.

Web crawling, also known as Indexing, is used to index the information on the page using bots also known as crawlers. Crawling is essentially what search engines do. It’s all about viewing a page as a whole and indexing it. When a bot crawls a website, it goes through every page and every link, until the last line of the website, looking for ANY information.

Crawling means “following your links”. Search engine crawlers fetch the links and submit the data to their search engine for indexing purposes.

Web crawling is the process of indexing data on web pages by using a program or automated script. These automated scripts or programs are known by multiple names, including web crawler, spider, spider bot, and often shortened to crawler.

Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. The goal of a crawler is to learn what webpages are about. This enables users to retrieve any information on one or more pages when it’s needed.

I’ve had to do some web crawling a couple of times for projects where I needed to collect large amounts of info from different websites, for stuff like comparing product prices or keeping up with job listings across multiple boards. It’s basically using a program or tool to automatically go through web pages and grab data, way faster than you could do by hand. The crawlers move link to link, copying what you need. Doing it yourself can get tricky with sites blocking you or changing layouts, so I ended up looking for better tools instead of building my own from scratch.

If you want something more reliable or need to scale up, I’ve found some helpful services online that focus on web crawling and scraping in a straightforward way. There’s more info about web crawling and automation at https://crawlbase.com/, if you’re curious to dig deeper or see some use cases.

Crawlers are bots that go through websites and collect data for search engines. They copy page content so it can be found quickly via search. Basically, it's how Google and others figure out what each page is about
