Search engines spiders: spider names and what search engines they belong to

Do you know the spiders?

If one ever wondered if search engine engineers were a whimsical lot, one only needs to looks at the names of search engines’ spiders to find the answer. Googlebot, Slurp, Ask Jeeves and ia_archiver are some of the spider names used by the most popular search engines on the web.

Which search engines uses spiders to fetch documents?

Using a program called a spider, search engines continually search the web looking for new pages and reviewing documents they already have in their index. You may ask, “Which search engine uses spiders to fetch documents?” and the answer is, “All of them.” Without a spider, search engines would not be able to find new pages.

Why name a spider? Search engines don’t have to.

The main purpose of spider names is so that search engines’ spiders can be easily identified in your site logs. When was the last time you looked at your logs? Today, with the availability of free tracking software, such as Google Analytics, many people never look at their logs, but if you do, you will see the spider names from the search engines appear all over it.

Think of it as a courtesy. Certainly the search engines’ spiders could arrive at your site under the name “Mozilla” which is how most web browsers appear in your logs, but the search engines don’t wish to be rude. By using spider names, they let a site owner know that they have been by to visit.
