Google MayDay update significantly changed the Google algorithm and is affecting long tail traffic of major websites, as Google attempts for “higher quality sites to surface for long tail queries“.
Caught by the Google MayDay buzz at WebmasterWorld with crashing traffic reports by webmasters, Google’s Vanessa Fox writes –
This change seems to have primarily impacted very large sites with “item” pages that don’t have many individual links into them, might be several clicks from the home page, and may not have substantial unique and value-added content on them. For instance, ecommerce sites often have this structure. The individual product pages are unlikely to attract external links and the majority of the content may be imported from a manufacturer database. Of course, as with any change that results in a traffic hit for some sites, other sites experience the opposite. Based on Matt’s comment at Google I/O, the pages that are now ranking well for these long tail queries are from “higher quality” sites (or perhaps are “higher quality” pages).
This is a major change in Google ranking strategy which will definitely change the search engine ranking of many sites. Create good unique content and present it as a good site architecture Google via sitemaps, robots.txt and META tags, and you should be fine.
