Welcome to WebmasterWorld Guest from 184.108.40.206
I have campaigns for several websites, many campaigns for just one website, and one compaing for another 3 websites. I didn't notice just one website was affected, the one with lots of campaigns.
This website has a very particular linking strategy, as I have a list of about 50 products and each product has a sort of mini-portal, with its own subdomain like:
So, I wonder, if there's something about the use of subdomains here. I sort of remember someone reporting problems with subdomains in the past.
BTW, the slap was exactly on Friday Apr 11th, at 12:00 PDT
On Fri 11th we got slapped hard by Google. Our bids which were normally 5c-10c cpc with a great QS jumped to $10 for a min bid. This was on a site that had been doing extremely well for the past few months then with no warning Bam!~
This site had a similar set up to what you described: lots of campaigns all leading to different landing pages for different products.
Have tried several things to revamp the campaigns but nothing seems to be working.
