Ce penalizari sa atraga? Google daca vede ca nu le implementezi corect si faci abuz (sunt multe exemple cu hreview aggregate, sunt bagate "cu forta" in cod fara a avea posibilitatea sa dai rating pe undeva prin site) este foarte posibil ca orice altceva ai implementa in site sa nu ti le mai arate niciodata in SERP's. De penalizari pe asa ceva nu am auzit niciodata.
@edy vezi ca sunt mai multe formate : schema.org (microdata) astea sunt recomandate de google, RDF'a, microformate (microformats.org) si Good Relations, http://www.heppnetz.de/projects/goodrelations/ (pentru ecommerce) http://www.ebusiness-unibw.org/tools/grsnippetgen/ generator de cod pentru a le implementa mai usor. Pot sa iti dau linkuri catre toate, dar ar fi bine sa le cauti si tu singur.

DS: asks question about rich snippet spam
MC: Used to be that people wondered why it was so hard to get rich snippets, now it’s the other way around. We’re looking at ways to handle the abuse … missed the exact quote, but he said something about maybe removing ability for a domain to have rich snippets if there’s abuse.
Ce iti recomand sa folosesti este hReview (rating), hCard (pentru adresa fizica, ajuta la local seo), hProduct pentru produse la ecommerce.
