Buying Text Links

Ads used to have tracking links so that webmasters could measure their return on investment; however, today's text linkers often prefer to keep the tracking codes off because their web analytics software no longer needs them. And besides, if you're going to buy an ad, you might as well get the possible link popularity credit that comes with it. That's more likely to happen with a plain old, stripped-down href link.

Unfortunately, this is wreaking havoc with search engine algorithms. On the one hand, they know it's not their place to tell people whether they should or should not advertise on other sites -- especially since most of the engines are advertising companies in their own right. On the other hand, without any way to figure out which links are truly a vote for a site, and which are simply a paid ad, the relevancy of the search results for any given keyword phrase can be skewed towards those who are willing to put their money where their mouth is.
