Dear all:

In his talk at the Search Engine Strategies 2009 conference in Chicago this
week, Jay Myers, Lead Web Development Engineer for Best Buy, Co., Inc.,
reported very surprising effects of adding GoodRelations and RDFa to their
products pages:

1. GoodRelations + RDFa improved the rank of the respective pages in Google

In fact, if you try the query "BestBuy Ferris Bueller" on Google, then the


comes on rank # 1 ahead of the much more established page

d=7590289&id=47476> &id=47476

This indicates a strong effect of GoodRelations + RDFa on Google's
appreciation of a page. It is particularly surprising since the age of a
domain has now a huge influence on ranking in Google (older ones get a much
higher ranking), and the semantically augmented one is only something like
eight weeks old.

2. Jay also reported a 30 % percent (!)  increase in traffic on the BestBuy
stores pages, e.g.


since they have been augmented by GoodRelations + RDFa rich mark-up. 

3. Yahoo observes a 15% increase in the Click-through-Rate (CTR). 

Nick Cox from Yahoo also recently reported that augmented search results,
e.g. those with GoodRelations / RDFa in Yahoo get a 15 % higher
Click-through-Rate (CTR).

So in short: While better visibility in traditional search engines is of
course not the main intended effect by adding GoodRelations & RDFa rich
I think these findings are so substantial that any SEO / SEM consultant
should apply it - now!

Patterns for simple copy-and-paste are here:
