The site then tries to monetize their traffic with PPC or other ads.
Well, here’s an insidious twist. A popular company has a site at domain.com. Someone else registers wwwdomain.com, in an attempt to draw visitors who inadvertently leave out the dot.
This wwwdomain.com site has one page advising visitors to check their spelling, but also before continuing, please take a second to check out such-and-such. Then there is a Google search box with a high-priced PPC word in it. The user is encouraged to press the search button.
The high-priced PPC word has absolutely nothing to do with the original domain that the visitor mistyped.
I don’t know if this is generating significant revenue for the site owner, but it is a real slap in the face to those of us who advertise on the high-priced keyword.
There was one other site that was preloading search terms into the search box, and it was not kicked out. It's a blog, and they had a different search term in the box after each blog entry. Now they are still running AdSense ads, but the Google search box in each entry is blank.
I guess that's better than nothing.
