From martin.hepp at ebusiness-unibw.org Thu Dec 10 11:40:34 2009 From: martin.hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Thu, 10 Dec 2009 11:40:34 +0100 Subject: [goodrelations] GoodRelations + RDFa have huge impact on Google Rank and CTR Message-ID: <4B20D022.20207@ebusiness-unibw.org> 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 http://products.semweb.bestbuy.com/y/products/7590289/ comes on rank # 1 ahead of the much more established page http://www.bestbuy.com/site/Ferris+Bueller%27s+Day+Off+-+DVD/7590289.p?skuId=7590289&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. http://stores.bestbuy.com/1895 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!

By the way, I suspect the main reason is that by the very design properties of linked data, i.e., 1. link specificity and 2. higher link density, pages with GoodRelations & RDFa represent higher grades when the information value is assessed in an algorithmic way. I suspect that Google and others will soon implement changes to the algorithms that will check whether the rich meta-data 1. makes sense and 2. is consistent with the unstructured content in order to prevent abuse. So they will have to use semantic technology at least internally ;-) Martin Steven Forth wrote: > Game Changing Martin > > We need to get this news out there, it will lead to a huge shift in > behaviors.

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.

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 http://products.semweb.bestbuy.com/y/products/7590289/ comes on rank # 1 ahead of the much more established page http://www.bestbuy.com/site/Ferris+Bueller%27s+Day+Off+-+DVD/7590289.p?skuId =7590289 &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. http://stores.bestbuy.com/1895 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!

I can and will do something speacial for goodrelations for sigma but i cannot but wonder if the model needs those pieces, Sigma also commits to provide a simplified RDF to people who want it. I could understand providing not just a key value pair description but an extra noda saying for example "iphone" (node1) ---> "find it on sale at bestbuy for $199" (node2, a node with all those other properties attached) but yet more and more nodes (e.g. 2-3 like here) seems too much. Could i come up with a simplified node that is the offerincludingunitpricetypeandquantity node? to give to my sigma users? :-) how about adding that to goodrelations? wrt inspector and visualization please note that a complete "human readably" rdf representation is also available e.g. here http://sindice.com/developers/inspector/?url=http://products.semweb.bestbuy.com/y/products/7590289/&doReasoning=true#fullcontent which is complete, albeit less intuitive than the sig.ma representation. should we put this one first instead of sig.ma? should we allow the user to pick which node sigma looks at (sig.ma is entity based, needs to pick 1 node). notice that soon we will be announcing the inspector as a omnicomprehensive tool for validating web data, syntactically (including the w3c validation), semantically, and more (best practice validator including the "pedantic" web validation, linked ontology check (already in place), so we want this to be as good as developer friendly/useful as possible.

All tools are available on-line and most are also released as sourcecode under LPGL. 1. Generic Tools a) RDF2DataRSS: =============== Yahoo accepts RDF only as either RDFa embedded into existing Web pages or via their proprietary DataRSS feed format. The RDF2DataRSS tool turns any RDF data submitted as RDF/XML or Turtle/N3 into such Yahoo feeds and can be used to submit RDF/XML into Yahoo's SearchMonkey index. http://www.ebusiness-unibw.org/tools/rdf2datarss/ b) RDF2RDFa converter: ====================== This tool creates handy snippets of invisible RDFa from RDF/XML content such that the RDF can be pasted easily into any existing page without hard-wiring it with the HTML page mark-up. http://www.ebusiness-unibw.org/tools/rdf2rdfa/ 2. Tools for Creating GoodRelations Data a) Google Product Feed Converter: ================================= Many shops are already exposing their product and price information in one of the proprietary Google feed formats (RSS 1.0, 2.0 / CSV-based). With our tool, you can generate GoodRelations RDF/XML data from that data. That can be particularly interesting for adding RDF export to existing shops easily. http://www.ebusiness-unibw.org/tools/google-product-feed-converter/ b) BMEcat2GoodRelations converter: ================================== BMEcat is a popular XML Schema Definition (and DTD) for exchanging catalog data between enterprises in B2B settings. Many PIM, shop, and ERP software packages can create BMEcat XML documents. This tool transforms a BMEcat catalog into a GoodRelations-variant in RDF/XML. It can reuse / preserve more features than any other tool. http://www.ebusiness-unibw.org/tools/bmecat2goodrelations/ By the way, a free tool for creating BMEcat catalogs is at http://www.eclass.de/user/software/democat_2_0.zip (in German only, unfortunately). c) GoodRelations Annotator: =========================== A straightforward form-based Web application that creates a detailed company / business profile in RDFa and RDF/XML. http://www.ebusiness-unibw.org/tools/goodrelations-annotator/ d) Plug-ins / Extensions for Shop Software: =========================================== * osCommerce Shop Software: http://code.google.com/p/goodrelations-for-oscommerce/ * Joomla/Virtuemart CMS/Shop combo: http://code.google.com/p/goodrelations-for-joomla/ * Magento shop software: Contact Uwe Stoll, http://www.semantium.de/ (demo shop at http://www.la-mousson.de/) 3. GoodRelations-compliant Domain Ontologies for Vertical Industries a) ClassOWL 5.1.4 Products and Services Ontology ================================================ * OWL or HTML: http://www.ebusiness-unibw.org/ontologies/eclass/5.1.4/ (Warning: The file is very large - 38.3 MB for RDF/XML and 71.8 MB for HTML): * ZIP: OWL+HTML: http://www.ebusiness-unibw.org/ontologies/eclass/5.1.4/eclass_514en.zip (eClassOWL 5.1.4 ontology and documentation, compressed - OWL + HTML, zip, 4.7 MB): b) freeClassOWL - Ontology of Construction and Building Materials ================================================================= * http://www.freeclass.eu/freeclass_v1 (add .html / .owl if content negotiation should fail) c) Consumer Electronics Ontology (CEO) ====================================== * http://www.ebusiness-unibw.org/ontologies/consumerelectronics/v1 (add .html / .owl if content negotiation should fail) 3. Applications for Inspecting and Consuming GoodRelations Data a) iGoogr: "Imagine Google was using the GoodRelations vocabulary for e-commerce" ================================================================================= A quick demo of how Google search results could be improved by GoodRelations meta-data; also useful for inspecting your own page, because it fetches and parses RDFa in real-time. http://igoogr.appspot.com/ b) GoodRelations Statistics =========================== A tool that collects and exposes detailed data on the popularity of GoodRelations elements in the wild (with RDFa export of the stats!). http://goodrelations-stats.appspot.com/ c) GoodRelations Validator (alpha) ================================== A tool that spots semantic inconsistencies in GoodRelations data beyond the axioms of the ontology. http://www.ebusiness-unibw.org/tools/goodrelations-validator/ Much more is on our agenda for 2010, so please stay tuned by * bookmarking http://www.ebusiness-unibw.org/wiki/GoodRelations and * subscribing to http://ebusiness-unibw.org/cgi-bin/mailman/listinfo/goodrelations .

But you need them as individual nodes because that is the only valid modeling pattern for higher arity relations in RDFS/OWL. But there are cases where you want to reuse such nodes, e.g. when you have multiple offers that just differ by e.g. the eligible country or other properties of the gr:Offering. > I can and will do something speacial for goodrelations for sigma but > i cannot but wonder if the model needs those pieces, Sigma also > commits to provide a simplified RDF to people who want it. > The models needs those pieces. There is no other proper way if separating units from values etc. You can hide the complexity of higher arity relationship types in any user interface. But you cannot eliminate them in your conceptual model. Premature simplification is evil (D. Knuth, if I remember correctly). > I could understand providing not just a key value pair description > but an extra noda saying for example "iphone" (node1) ---> "find it > on sale at bestbuy for $199" (node2, a node with all those other > properties attached) but yet more and more nodes (e.g. 2-3 like here) > seems too much.

You can model pharmaceuticals using the very same patterns as those shown in http://www.ebusiness-unibw.org/wiki/Modeling_Product_Models for other types of goods. It may be helpful to complement that by an ontology for pharmaceuticals, e.g. organized by indication or substances. That ontology should follow this recipe, which will maximize its compatibility with GoodRelations and other data sets: http://www.ebusiness-unibw.org/wiki/GoodRelations#Creating_New_Vocabularies_for_Products_and_Services If anybody on the list is up for this or could help establish a contact, that would be great!
