Search Engine Spiders

Spiders, bots and crawlers

Seach Engine Spiders are software programs developed by the search engines that crawl the web for websites just to add them to their database. Spiders “read” your meta tags and see how far they are allowed to crawl into your website. (index-follow tag).

A spider or web crawler is a program that visits Web sites and reads their pages and other information in order to create entries for a search engine index. The major search engines on the Web all have such a program, which is also known as a “crawler” or a “bot.” Spiders are typically programmed to visit sites that have been submitted by their owners as new or updated. Entire sites or specific pages can be selectively visited and indexed.

Well known bots

Spiders are called spiders because they usually visit many sites in parallel at the same time, their “legs” spanning a large area of the “web.”

Spiders can crawl through a site’s pages in several ways. One way is to follow all the hypertext links in each page until all the pages have been read.

  • GoogleBot.
    Googlebot is obviously one of the most popular web crawlers on the internet today as it is used to index content for Google’s search engine.
  • Bingbot.
  • Slurp Bot.
  • DuckDuckBot.
  • Baiduspider.
  • Yandex Bot.
  • Sogou Spider
  • Exabot.
