Google Tweak Duplicate Filter Algorithm? http://www.webmasterbrain.com/seo-news/google-news/google-tweak-duplicate-filter-algorithm/ <p><a href="http://www.threadwatch.org/node/3985">ThreadWatch has a summary</a> on what according to speculation from WebmasterWorld members appears to be a alteration (appearing last Friday) in Google's duplicate filter algorithm. At least some webmasters' have experienced dramatic drops in ranking:</p> <blockquote> <p> Something has been tweaked by Google last week. It has not effected all sites, but has certainly knocked some of my sites that were hit by the last “canonical pages” and “duplicate content” issues at Google.</p></blockquote> <p>WebmasterWorld member, Caveman, believes it's more that just a change in Google's duplicate filter:</p> <blockquote> <p> The dup issue that steveb outlined so well explains some of what I see, but not all of it. There are cases where established site homepages and subpages are holding their ranking for one phrase, but dropping out of the SERP's for another closely related phrase (when the site previously ranked for both) ... and where there is no evidence of dup content filters playing a role where pages dropped out. They've tweaked something else IMO. Possibly related to linking/anchor text/kw patterns. </p> </blockquote> en Copyright 2005 WebmasterBrain.com webmaster@webmasterbrain.com Thu, 07 Sep 2006 14:31:13 GMT Thu, 07 Sep 2006 14:31:13 GMT http://www.webmasterbrain.com/img/logo.gif Google Tweak Duplicate Filter Algorithm? http://www.webmasterbrain.com/seo-news/google-news/google-tweak-duplicate-filter-algorithm/ Site Dropping http://www.webmasterbrain.com/seo-news/google-news/google-tweak-duplicate-filter-algorithm/site-dropping/ &lt;p&gt;HI:&lt;/p&gt;&lt;p&gt;My site and all 611 indexed pages completely dropped out of google. My ranking was great. I did resubmit it. Will they just pick it again where I left off off or do I have to start at the bottom again.
