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).
