Says Aaron, “This tool was designed to add more data to Google and Yahoo! to make it easier to evaluate the value and competitive nature of a market.”
The tool allows you to perform various SEO research functions as you search Google or Yahoo – which is very different than the toolbar and right click options offered by tools like SEOpen. With SEO for Firefox, after each search result you’ll see a variety of information for each URL ranging from age of domain name to .edu & .gov links to del.ico.us and dmoz info. The SEO for Firefox tool can be toggled on or off universally, plus there are settings for each data point.
Besides the info per url, there is overall information available for the query with links listed below the search box including: Google Trends, SEO Book Keyword Research Tool, Overture View Bid, Google Traffic Estimator and Google Keyword Sandbox.
Addition:¬† Be conservative in your use of this tool. Do not leave it on during regular searching as you may get temporarily blocked from the data sources including Google and Yahoo. Notes of caution are included about the tool’s use in the “how to notes“.
