Dear all: As many of you know, Google has been pretty slow in the past with turning on Rich Snippets (augmented search results) for shop pages that expose GoodRelations rich data markup. Today, I found a shop that added GoodRelations ca. five days ago (!) and is already showing Rich Snippets in Google. See the illustration at http://yfrog.com/hsf45sp for details. The shop obviously uses the new free extension for Prestashop [1], developed by Makolab in Poland. Similar results should be obtainable using the other free extensions from [2], e.g. for Magento, Joomla/Virtuemart, OXID eShop, or for a Tradoria.de shop. I personally think that one of the reasons for the much faster than usual activation of Rich Snippets for this shop is the fact that Prestashop has pretty good XML sitemap support on board, which allows Google to crawl the shop faster with less resources and thus helps updating the index faster. See http://asiavshop.de/sitemap.xml The critical aspect of a good XML sitemap is that it uses the "lastmod" attribute properly for indicating which pages changed when: <url> <loc>http://asiavshop.de/sushi/92-sushi-reis-1kg-shinode-8005734100059.html</loc> <priority>0.7</priority> <lastmod>2011-12-15</lastmod> <!-- this line is crucial --> <changefreq>weekly</changefreq> </url> Best wishes Martin Hepp [1] http://addons.prestashop.com/de/seo/3866-rich-snippets-and-semantic-seo-with-goodrelations.html [2] http://wiki.goodrelations-vocabulary.org/Shop_extensions -------------------------------------------------------- martin hepp e-business & web science research group universitaet der bundeswehr muenchen e-mail: hepp at ebusiness-unibw.org phone: +49-(0)89-6004-4217 fax: +49-(0)89-6004-4620 www: http://www.unibw.de/ebusiness/ (group) http://www.heppnetz.de/ (personal) skype: mfhepp twitter: mfhepp Check out GoodRelations for E-Commerce on the Web of Linked Data! ================================================================= * Project Main Page: http://purl.org/goodrelations/
