About me• Decadesworking with Semantic Technologies in finance, government, insurance and more• Currently – Major Online Retailer• SD Semweb organizer, assistant SF organizer, etc• Added goodrelationsrdfa onto some 900,000 item pages – Looking at all kinds of backlinks from many e-tailers sites certainly demonstrated the necessity for structured data within web pages or a “less gameable” search solution.
What I am going to talk about• The Wave• How to catch it• Why• The catch?• Demo
Some basic definitions• RDFa - RDF in attributes• Rich snippets, embedded structured data on html pages• Typically used initially by the search engines to enhance displays in SERPs• Rich Snippets yield increase in CTR (Click Through Rate)• Initial claim – no change in search rankings
How to catch the wave• Add rdfa to your website• Either directly or using tools – Great goodrelations support for rich snippet generation – Wordpress plug ins and other tools available – Drupal support – Others
Benefits• Increase in CTR• Visibility in search engine verticals – Local search – Shopping• Definite ranking increase for verified, validated data (e.g within product search)• Visibility in other engines/apps consuming RDFa• Mobile usage – massive market• Strong need for structured markup » Combat spam » Make information more findable » Read more an schema.org » …
Increase in CTR• Yahoo performed a study that showed > 15% increase in CTR on some sites as a result of using Rich snippets
Search Engine verticals• Additional rewards for encoding rich snippets on your site.• Search verticals leveraging consumption of structured data• Products, recipes, places ..
So what is the catch or is there one?• Adoption June 2, 2011 JUST IN TIME FOR SEMTECH 2011?• Ease of use• Standardized vocabularies• Complex nesting of divs and spans• There is a need for standardized vocabularies, so how can we now best leverage microdata and Schema.org?
