page suddenly shows PSA ads

[waiman39hk]

One of my page today suddenly shows PSA ads only.
I refreshed again and again but the situation doesn't change. So I renamed the filename, the target ads appears again.

Anyone have same experience as me? And what do u think is the cause?

What type of ad is it?....text only, text and image, or image only....as people have mentioned that image only ads gets this due to lack of available images to show?

I have had the same in the past, and it was worse.
About 10 of my pages suddenly showed PSA's and untargeted ads. After a week I changed the file names and I got targeted ads again. Very annoying cause your pages have to start at square one again in the serps. I asked Google about it but got some canned reply. BTW, ads were regular text ads and there were plenty of advertisers.

My ad setting is text + image. Plenty of adveristers all the time.

I have to use 302 redirect to take care of the problem. If I use .htaccess to rewrite url, PSA appears again.

I was sometimes worried about if G penalize my page for some reason, eg. poor conversion rate?
