There are so many cool SEO extensions for Firefox but it’s the first time when I’ve come across an SEO plugin for Opera. SEObar is a powerful SEO tool for Opera users. It can do a few neat things:

• Highlight nofollow, noindex or external links (with different colors).
• Display the Alexa rank and Google PR
• Display DMOZ and Yahoo! Directory data
• Show the number of pages indexed in Google, Yahoo! and MSN. It also displays Yandex (Russian SE) data.
• Display the number of backlinks (by search engine).

The information is displayed in the SEObar’s panel and the browser’s status bar. Visit the SEObar site to find out more info about this handy JavaScript file.
