I've registered here to ask one question about new canonical tag.
Recentrly (Feb. 12) Google, Yahoo and MSN announced a new html tag for removing duplicate content from search engines.
You can read about it on Google Webmaster Blog, Yahoo blog and also on Microsoft website.
The usage of canonical tag:
<link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" />
Now, why I told about it...
IPB forum engine is well known duplicate content generator for search engines. You can see it yourself in Google SERP. A lot of duplicate content what make search engines cesspool. It will be very useful if you can update engine in next versions to use this tag on various pages.
I want IPB Forum to be a seo optimized and think all user will maintain me in this topic.
