Search engine optimization is not for the faint of heart, but now there is a free SEO toolbar from SEOmoz for both Firefox and Chrome.
The new toolbar is called the MozBar, and it offers easy access to key SEO tools and data while you surf the Web. Users of the toolbar can see SEO metrics at a glance while they’re browsing, and an Analyze Page overlay exposes metrics and page elements
Meanwhile, a search engine results page (SERP) overlay, offers detailed link metrics for Google, Bing and Yahoo.
Users can even save up to 10 search engine profiles that you commonly use and quickly open and compare the results for each.
