Different Ads on http://www and http://

[h3k27]

Ive just noticed it, when I access my site using [mysiteurl.org...] then I get the ads relevant to my keyword. But when i only use [mysiteurl.org...] (without the www) i got PSA or other unrelevant ads..

Whats the difference?

Perhaps Google doesn't "know" your site (yet) w/o www; if it doesn't know what your site is about, it doesn't know which ads to show...

BTW, I would consider setting op a 301 redirect from non-www to www, if I were you...

Google considers each of these to be a different page, so our crawlers will index each page separately. It sounds like one of your pages may not have been crawled yet, leading to less relevant ads appearing.

It you've just pasted the code, give our crawlers a couple of days to index both of your pages. The ads should become more relevant with time.

I had this problem once upon a time and a quick 301 redirect fixed it and actually improved my SERPs when the dust settled.

I have noticed this and I have another site where the ads have been "stuck" on PSA ads for a couple of days now.

The sub pages of the site all show ads fine, but the main page always shows PSAs no matter what text content I put there.

What causes the google engine to choose PSAs? Have I done something in my front page layout to cause this?

thanks!
