Googlebot

Hey guys, we all know that Pagerank is an important one for all of those, who owns a website or a blog and we also try very hard to get a pagerank or increasing the excisting one. And we also wish that our webpages should be indexed on the google search engine as soon as it can. But do you know who is allotting this Pagerank and indexing our webpages in the google search engine. Is it done by only one person or a group of people? Who is doing this work for google? The answer is Googlebot. A Googlebot is a search bot used by Google. It collects documents from the web to build a searchable index for the Google search engine.

If a webmaster wishes to restrict the information on their site available to a Googlebot, or another well-behaved spider, they can do so with the appropriate directives in a robots.txt file, or by adding the meta tag <meta name="Googlebot" content="nofollow" /> to the webpage. Googlebot requests to Web servers are discernible from their user-agent string 'Googlebot'.

Googlebot has two versions, deepbot and freshbot. Deepbot, the deep crawler, tries to follow every link on the web and download as many pages as it can to the Google indexers. It completes this process about once a month. Freshbot crawls the web looking for fresh content. It visits websites that change frequently, according to how frequently they change. Currently Googlebot only follows HREF links and SRC links.

Googlebot discovers pages by harvesting all of the links on every page it finds. It then follows these links to other web pages. New web pages must be linked to from another known page on the web in order to be crawled and indexed.

A problem which webmasters have often noted with the Googlebot is that it takes up an enormous amount of bandwidth. This can cause websites to exceed their bandwidth limit and be taken down temporarily. This is especially troublesome for mirror sites which host many gigabytes of data. Google provides "Webmaster Tools" that allow website owners to throttle the crawl rate.

Thus I think that all of you had now got the answer for the riddle with the help of my post. Thank you for reading this post and keep in touch to know more about unrevealed matters…
