Canonical Link Element
In short, the canonical element is a line of code that you add to pages that may be duplicates. The canonical link element rel="canonical" is added to a page within the header () of a page, typically by developers, as follows
In this code, you designate the "canonical," or "proper," URL. Engines, in turn, note this URL and apply link popularity and authority to the canonical version instead of applying them to duplicate URLs.
This provides a hint to a search engine about which is the most important or original page if pages are identical or similar in terms of content, but have a different URL.
Google and other search engines announced support for a canonical link element that can help site owners with duplicate content issues.

Lots of rumors and gossips were spread out among webmasters and finally the wait ended up in the first week of April. This time Google crawled for both Page rank and Backlink.

Bing brings a new way of thinking to using SERPs, which has shown to demonstrably improve the satisfaction of searchers in finding the answers to their questions.
5) June ‘09
No More Page Rank Sculpting
PageRank sculpting is an SEO tactic that involves adding the nofollow attribute to links for which PageRank flow is not necessary. Early in 2005, the main search engines introduced a ‘nofollow' attribute for the A HREF HTML command for coding hyperlinks.
Nofollow is also used extensively in social networks and in forums to limit any value comment spammers get from posting in the forums to their own sites for SEO benefits. PageRank Sculpting was one of the controversial issues among the webmaster. But the engines have evolved their thinking. They realize now that rel=nofollow is a much more versatile tool than when it was first conceived
pagerank sculpting used to be really effective around a year ago but Finally Matt Cutts announced in his blog that it's not the most effective way to utilize your page rank and its not recommended.
Increase in Social Media Importance
With the continuing evolution of the Internet, and increased adoption of web 2.0 functionality, social media activities and discussions are going to take on a more important role in the eyes of a search engine. Social media has provided its users with unlimited opportunity to decide the relevancy of content. The financial downturn will encourage more marketing executives to turn to organic social media initiatives to drive awareness and interest. All in all, 2009 looks to be a year of significant growth for social media.
Discussion forums have built the trust in the eyes of Google. It's really not a surprise now if forum threads are been displayed in Google's 1st page of SERP.
