This tool does exactly what it says. You input a list of keywords and a domain, and it will tell you what page, and where your site ranks for those keywords. This tool will save you hours of scouring search results looking for your site. One word of warning though, the ranks are not always 100% accurate. However, most of the time they are very close and serve as a good estimation of where your site ranks.

Not only is it a toolbar that displays PR, internal links, external links, links to the domain, Alexa Rank, a link to Whois information, Delicious Bookmarks of the page, and the number of pages indexed in Google and Bing, it also adds that information to your Google Search results. This tool is one of the most comprehensive SEO toolbars available. A word of warning though, when you are not using it, it is best to turn it off. Due to the amount of information that the toolbar gathers, sometimes Google will not return search results because you are running too many automated queries.


This is more of a developer tool, but it can be very useful for SEO as well.

It is useful for seeing whether elements are created using CSS or HTML, or debugging a website that you are developing.
