I've noticed that some online tool sites like photohosting and mail storage put adsense on their pages. Given the dearth of content targeted text (since it's the users that are making the content), the ads that show up are rarely targeted to the content OR are generic (ie., relates only to file hosting or whatever the tool is). Any ideas on how to fix this?
The only thing that I can think of is to use section targeting. Google details it here: https://www.google.com/support/adsense/bin/answer.py?answer=23168 The HTML tags to emphasize a page section take the following format: <!-- google_ad_section_start --> <!-- google_ad_section_end --> You can also designate sections you'd like to have ignored by adding a (weight=ignore) to the starting tag: <!-- google_ad_section_start(weight=ignore) --> With these tags added to your HTML code, your final code may look like the following: <html><head><title>Section targeting</title></head> <body> <!-- google_ad_section_start --> This is the text of your web page. Most of your content resides here. <!-- google_ad_section_end --> </body> </html> Simply block out the areas the the users have their random input and put the weighted areas around your content that you want the ads to be related to. Someone that has been around here longer may have a better idea...
Fresh content takes time to get spidered by google. To help get the ads targeted to content you could use section targeting. However for new content google users the main keywords for the site e.g. from the meta tags, the site title etc.
For example, if a user is going to upload a file and distribute it to his friends using my online tool, I'd like the PPC ads to reflect the category of the file he's sending. Example: Guy sends a picture of his dog to his friends. It would be nice to see PPC ads that are about dog care, dogs, and dog photos. Relevancy = higher click %
