Although I’ve been using other SEO browser tools for the awhile now, this one came to my attention for its immense possibilities of configuration and the fact that with just a glance, you can see pretty much everything about a domain without leaving the site you are visiting.

Some of the info you’ll be able to see on your toolbar:

* PR – PageRank
* Links on Google
* Links on Yahoo
* Links on Yahoo Directory (the. COM)
* indexed pages in Google
* indexed pages in Yahoo
* indexed pages in Bing
* Domain Age
* Alexa Ranking
* Source Code
* Domain Whois
* Inbound Links
* Outboundlinks
* keyword density

The novelty here is that is available for both Firefox and Internet Explorer.

Install SEOQuake in at least one of your browsers and ‘spying’ on your competition will get a lot easier..

If you have questions or problems once installed, just ask me on Twitter because I have it installed on 6 computers with all kinds of configurations of OS, hardware, etc.
