I Just thought of a big possible problem with AdLinks in terms of Invalid Clicks and AdSense abuse.
Remember a few days ago, we were discussing the problems of publishers who abuse Adsense by asking visitors to click onto the Adsense Ads. Well with the new AdLink Search Box, when a page is not displaying AdLinks Ads, it displays a search box which allows the visitor to enter a term to search for an ad. Now can you imagine the things we'll soon see:
"Please help support us by entering the word 'Mortgage or Metho...' into this box, hit enter and then click onto the ads on the next page".
Lets just hope Google's systems pick this up or there'll be more trouble ahead for the advertisers.
AdSense for Search has been around for a while and this has been a problem. I've never seen a site that asked the visitor to type in a certain word. But I have seen sites that had the high-priced word preloaded in the search box. The user just has to press the search button. These sites showed up in my logs (I'm an advertiser), so I complained. But I'm sure there are other sites in other industry doing the same thing.
