Yet another reason why Google is awesome: Webmaster Tools
Webmaster tools is the greatest tool for anyone wanting to get their sites up in the search engines. Search Engine Optimizers who don’t know about this tool, aren’t really search engine optimizers.
You prove to them that you own your website in one of two ways: 1) uploading an .html document to the server with a certain name like Google2903ncvd90nk30.html or 2) add a meta tag to your home page with a similar random name. After that, Google will get you all the information that they have about your site!
The program will tell you all of the crawl errors that the Google bot has while crawling your site! So if your site has gone through a couple redesigns or upgrades, I guarantee there are pages that used to exist that Google can’t find. And everyone of those pages create a 404 error for the Google bot – which, by the way, is not good. But you’ll never know unless you get this tool and find out!
Its got endless tools like that. It has a robot.txt analysis page that will tell you if you have any problems with your robot.txt.
It will tell you how your pages are ranked by Google. It will tell you like 50% of your pages have medium page rank and the other 50% has low page rank. It will also tell you how many links you have directed to your website, and where they are coming from.
Google Webtools also has a place for you to submit your website’s site maps! (Get gsite crawler to create your sitemaps… It makes it as easy as pie.)
And I barely scratched the surface on all of the different tools available to you through webmaster tools.
