Dissapearing of ads

I just checked one of my sites and the usual ads that where showing up dissapeared. One is still there, but i had 5. Nothing changed at another site of mine though.

So does this mean those people stopped their campaign in AdWords or how can you explain that sudden loss?

Thanks in advance for any help.

 

There may be a drop in advertisement on your keywords, you are right.

 

Hm, ok thanks. Gotta change the placement of the ad again then.

 

Maybe work on your content. I do not feel placement will change you issue. Let us know what you find out.

 

What do you mean ads disappearing....I hope you know that Google adjusts the number of ads in an adunit to maximise your revenues.

 

@Server: Not really easy.. www.rehorror.net

I built the site to have good graphics, havent really thought about Google that much. And i like it that way. Maybe i'll figure something out.

 

i didnt know that google optimizes adverts - what do you mean exactly?

 

they will limit display ads in areas that have low CTR to push traffic to the higer CTR areas.
