My site has now vanished from Google
This is one of your long, long threads at WMW. Now 400 posts long it started a week ago and still going strong, got a renewed impetus on Friday, when a new Google filter kicked in. You can see the effect if you use the “&filter=0” to blot it out (eg “London hotels” as now, and ” “London hotels using &filter=0)
In message 188 Reseller quotes an old GG post as saying
“the "&filter=0" just shows all pages, even pages that appear to be duplicates. Normally if there are pages that appear to be duplicates, we try to pick the best one to show (but no heuristic can be perfect--it's like having two people claiming to own the same essay).
Caveman in post 171 says
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.
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. It seemed that their latest attempt to identify the “canonical page” is as flawed as the last one. If you have, like me, sites that have been badly scraped by others, then this “new” filter does as bad a job as the last one at identifying the canonical page.
I might add that Mr Cutts has not made an input on the WMW thread - wait till it blows over Matt!
