New York-based advertising firm MediaWhiz , never one to worry about gray areas when it comes to advertising, has launched a new product today called InLinks . It's fairly straightforward - advertisers who want their sites associated with specific keywords simply buy ads. Links to those sites are then added to publishers sites whenever those words pop up in content. These aren't ghost links like Kontera and others include in content - they're full blown links without any notation (like a nofollow) that they are advertisements meant primarily for SEO juice. Content sites are paid a flat rate per month per ad sold. I'm trying to get more details now from the company, but there is more on this here and here .
