A fews day ago I wrote about an excellent article regarding some free SEO tools available. Along with these tools, Firefox users should take a look at the SEO for Firefox Extension.

SEO for Firefox doesn’t make suggestions for your website, rather it gives you analytical data regarding the indexing and linkage to your site. Data is pulled from Google, Yahoo and several niche specific networking sites (del.icio.us, Technorati, Alexa, etc.) to provide you with information such as how many links to your site their are and your page rank. Keep in mind though, this data is limited to the sites the extension uses as its source.

There is extensive information about what the extension does available on its homepage, so take a good look if you are interested. One thing I would like to point out is to make sure the extension is used responsibly so you don’t send a bunch of unneeded traffic to source web site:

If you are casually surfing please turn this extension off. Only turn it on if you are actively researching a market.

This extension also has courtesy settings which allow you to ping search engines for data at a slow rate. You probably want to set the delay to at least 1 or more seconds. If you set it at 0 do not be surprised if some of the engines at least temporarily block you for scraping data.
