They will keep on producing both, but following our recommendation, the

RDF/XML will be a dump meant for crawlers only and collating the rich

meta-data from all RDFa mark-up.<br>

<br>

In other words, if you crawl the single RDF/XML, you will get the very

same set of triples (minus duplicates) as if you crawled all XHTML/HTML

and extracted all RDF from there.<br>

<br>

So the authoritative URIs will be those from the RDFa and if you

dereference an entity URI, you will go to the XHTML+RDFa resource.<br>

Yes, but please also show key values like price, payment, and delivery

options, even if those require parsing a single intermediate node.<br>

<br>

Also, you should use the ean ucc 13 property to suggest related

entities, even if this is a literal value instead of a URI. <br>

<br>

But be careful not to assume that all entities having the same EAN code

are the same entities (DON'T generate sameAs statements. Just link.)<br>

No. But for the moment, fetch the RDFa if that is easier for you.<br>

    <pre wrap="">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

    <a class="moz-txt-link-freetext" href="http://products.semweb.bestbuy.com/y/products/7590289/">http://products.semweb.bestbuy.com/y/products/7590289/</a>

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

<a class="moz-txt-link-freetext" href="http://www.bestbuy.com/site/Ferris+Bueller%27s+Day+Off+-+DVD/7590289.p?skuId=7590289&id=47476">http://www.bestbuy.com/site/Ferris+Bueller%27s+Day+Off+-+DVD/7590289.p?skuId=7590289&id=47476</a>

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.

<a class="moz-txt-link-freetext" href="http://stores.bestbuy.com/1895">http://stores.bestbuy.com/1895</a>

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!
