Has anyone experienced a penalty / filter for only .com and no effect
on any other world wide dc's ?
I'm tending to think it's a over optimization penalty but only applied on Google .com.
Main keyword phrases which are in the title still show on first page of every DC in the world except .com
I have made a lot of changes over the last 18 months but can't get the main phrases back within .com. They don't even show in the first 30 or so pages. Other keywords are still at number 1 and various top positions.
For the biggest 4-5 key phrases totally ignored by .com
The content of the home page barely mentions the phrases any longer Sub pages rank on page 2 for the same keywords though.
Any over optimization has long since gone but 18 months on still no return on the top 5 phrases in .com.
If anyone has experienced this any ideas on how long it lasts or if you ever overcame it ?
