SearchStatus

If you have ever wondered how popular your website is, then chances are you may have heard about some of the most popular website ranking services out there such as Alexa Internet, Compete, SEOmoz Linkscape or even the somewhat controversial Google PageRank.
You can clearly view the rank of any website from all of these services with the help of online rank checkers or, even simpler, directly from your Firefox web browser.

Website rankings, SEO and search-related tools, all available with the help of this extension

SearchStatus is a lightweight and useful Firefox extension (or add-on) that allows you to view the Alexa, Compete and SEOmoz Linkscape traffic rankings of any website.
Not only this, but the extension also provides you with a set of interesting SEO-related tools such as fast keyword density analyzer, keyword, and nofollow highlighter, backward and related links finder, as well as quick access to some of the most popular WHOIS and Internet archiving services.

If you're having trouble with SearchStatus, read the following

Please note that subsequent to is typical installation process, by default, the extension might not appear in Firefox's interface, as other add-ons do.
If this is the case, head over to Extensions section and click the 'Option' menu. From the General tab, you should be able to easily change its location until the search status icon finds its way on one part of the Firefox UI.

Guilelessly displays website rankings

From here onwards, things are quite simple, as you only need to access any website and the extension automatically displays the ranking for the aforementioned ranking web services.
It is worth mentioning that you can change the way the rankings are being displayed by simply right-clicking the specific sections. Furthermore, from the extension's contextual menu (accessible only via right-click), you can access some of the secondary features.

Useful extension that falls a bit short regarding looks and Firefox integration

All in all, SearchStatus proves itself to be a very useful companion for users who want to quickly determine the rankings of their websites or visited ones. One of the extension's highlights is the instant access it provides to some of the most useful SEO-related and other types of Internet tools.
Before the end, we are obliged to point out the fact that SearchStatus feels a bit rough around the edges. The extension does not look quite at home in some areas of Firefox's UI, its menus are on the old side of things, and the fact that you have to change its location after the installation for the extension to become active are just some of the facts that bear testimony to this.
