If you work as as an Search Engine Optimiser (SEO) chances are that you use Firefox as your main Browser (2nd  -  Chrome for quick research assignments/social networking,  3rd – Internet Explorer for backwards compatibility browser testing).

As we all know the power of a great application lies in it’s ability to be fully customisable and extended to however the user requires – Firefox doesn’t disappoint here. For SEO’s those extended requirements are to be able to see key information about clients, competitors websites  – there is no other browser on the market that comes close to be able to review/research sites, links, code etc for SEO’s. FireFox is the browser of choice for the professionals in the industry.

A couple of days a go Mozilla introduced Add-on collections. Add on collections are a way to share your favourite plugins with the community and help highlight the best extensions out there…

Watch this cool introduction video on how to browse, create, install collections.

The purpose of this post is to share with you my collection of SEO tools for Firefox that I use daily when working on clients sites. Below I’ve highlighted a few of my favourite plugins from the collection…

Google Global

Google Global is an unobtrusive Firefox extension that allows you to see what the Google search results that you are viewing look like from different geographical locations. Becoming one of my most used plugins when checking US SERPS results running of local data centres. (Googling this site for “Google Consultant in the US shows different results from simply searching the .com results. Listings  being pulled from different data centres as we all know give different SERP results.) Download >>
