home page getting irrelevant ads

all other pages seem ok!

hi everyone.

I have a website cotaining around 3,500 web pages with adsense running on all the pages. The site is a niche directory catering for a non-technical sector. I have notciced that since last night my home page has been getting php/sql/web hosting ads whilst the rest of the site has been getting the normal , well targetted ads. From looking at the code of the home page the only relevance I can find to the ads is that all of my links contain a .php extension. I'm surprised that the filename extensions of the links have more influence than the body text, headings and link text.

The index page validates for xhtml 1.0 transitional.

This seems to be killing my adsense performance. Has anyone seen anything similar or know of how to fix this?

Thanks in advance

Well, if it's the site in your profile then the index page ads are WELL off! There are plenty of relevant keywords for Google to work with. I really can't see how they managed to target php ads on your site. It might be worth asking adsense support to look at it for you.

hi david,

yes it is that site and i have contacted adsense support, guess i'll just have to wait and see what their response is.

i think i know what the problem was. it seems that i had some fatal php/mysql errors at the time that the freshbot spidered the home page. this meant that the error message (which is currently in google's cache), containing words like php db etc, is being used to determine context for adsense ads.

my guess is that the ads will become relevant again once freshbot gets a new copy of the home page.

You can prompt the bot to visit by changing the ad block and uploading it. Refresh the page in your browser until you see the new version, then put the original back. That seems to send the bot scurrying.
