What is a spider?

[seoinheritx1]

Spider is an robot that travels the web examining the websites in order to add them to a search engine database and rank them according to the specific ranking criteria for that search engine. The spiders will periodically come back to your site once indexed in their database. That is why it is important to constantly refresh your content, because the spiders will stop coming to your site if your content remains the same.

It is a program that most search engines use to find what’s new on the Internet. Google’s web crawler is known as GoogleBot. There are many types of web spiders in use, but for now, we’re only interested in the Bot that actually “crawls” the web and collects documents to build a searchable index for the different search engines. The program starts at a website and follows every hyperlink on each page.
