Now more than ever, SEO is so closely related to the live web that real-time actions and accurate and precise web analytics measurements are needed.

Blog farms and now the infamous “autoblog” (spitting out other people’s articles for cheap traffic) give way to misleading analytics metrics and misleading web statistics. Today’s Internet marketing professional needs tools that are easily accessible, accurate, and reliable.

Thanks to the growing popularity of open source development, app developers have been able to produce quite a few impressive SEO and web analytics tools that can be used to track page rank, backlink information, site health statistics, and analysis on the page. — All from the comfort of your favorite open source browser: Google Chrome and Mozilla Firefox.

#3 – SEO and website analysis (Firefox and Chrome)

The title of this SEO add-on is known as “SEO & Website Analytics” in both the Google Chrome Extensions Gallery and the Add-ons for Firefox directory. But sometimes it can also be called “SEO Report” (Chrome) or “SEO WooRank” (Firefox).

Whatever its title, this mighty little extension surely packs a punch on SEO by providing very in-depth website analytics and on-site SEO for any website.

As a tool for quick on-site analytics tracking, it does a great job. After installation, simply click on the WooRank icon that appears in your browser’s user panel to see a full SEO analysis of the website you are visiting.

#2 – Search Status (Firefox)

Touted by many web developers and SEO specialists as “the must-have Firefox plugin for SEO”, SearchStatus is a toolbar extension for Firefox and SeaMonkey. SearchStatus allows you to see the performance of each and every website in the world.

Designed for the highly specialized needs of search engine marketers, Search Status provides extensive search-related information about a site, all conveniently displayed in a compact, unobtrusive toolbar.

For every site you visit, SearchStatus gives you a simple visual layout of: Google PageRank, Google Category, Alexa Popularity Rank, Compete.com Rank, SEOmoz Linkscape mozRank, Alexa Related Links and Google Back Links, Yahoo ! and MSN. This search-related information means you can see not only the importance of a site’s links (according to Google and Linkscape), but also the importance of traffic (according to Alexa and Compete). This gives you a balanced view of the site’s effectiveness.

Most useful features:

• Google PageRank, Alexa Rank and Compete.com Rank toolbars for every page you visit
• Highlight nofollow links, access any page’s matatags with one click, view link report and robots.txt info
• Search Google and see your search history and Google suggestions
• Displays all publicly available information about a site’s domain owner, contact details, expiration dates, etc.
• Analyze the density of any keyword in any blog. SearchStatus divides the analysis into title tag, body, H1/H3 tags, etc. so you can optimize it much easier.
• Link Reports: Easily monitor links to any website. You’ll also see information categorized into external links, internal links, no tracking, and just about every link parameter a web SEO professional will need.

#1 – Quake SEO (Chrome and Firefox)

SeoQuake is a powerful browser plugin for Mozilla Firefox and Google Chrome. Its goal is to help browser users get real-time site information such as page rank, backlinks, and other important SEO parameters on the go.

I personally use SeoQuake on a daily basis. From day 1, I found it easy to use, reliable (doesn’t crash my browser and works great), and very accurate. Three excellent qualities for any SEO browser plugin.
