GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

[goodrelations] GoodRelations + RDFa have huge impact on Google Rank and CTR

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 tremendously. *

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


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


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 mark-up,
I think these findings are so substantial that any SEO / SEM consultant 
should apply it - now!

Patterns for simple copy-and-paste are here:
