Consider hiding ads on your site depending on how the user got there.
A friend of mine recently experienced an unexpected surge in traffic to his site. He's been subject to a rampage of Digg-ers ever since then, scrambling to cut his image and RSS bandwidth.
He's got some philosophical issues with showing ads on his site. I understand, but I think it makes sense to segment your users into two groups:
- Preferred users - These folks came directly to your site and will see no or minimal ads. Visitors who arrived via a bookmark or RSS feed link are unlikely to click on ads anyway.
- Walk-in users - these folks came to your site via search results or social recommendation sites like Digg, and can deal with a few ads. Visitors who found your site via search are looking for something and, heck, it just might come up in a contextual ad. Visitors who came via social bookmarking sites (on average) are a different class of user - they chew up bandwidth, spend a few seconds (3.6 seconds on average, to be precise) on your page, post an inane comment, and move on. They can deal with some ads to offset the trouble they're causing. Sure, Digg users aren't going to click on ads, but at least they'll contribute to the CPM ad count.
How to do it
I first read about this idea when David Brunelle added conditional advertising on his blog. It's a simple enough concept - check the referrer, and if they're in a list of domains, they get the ads. Our friends and co-workers and Moms who bookmark our pages don't get the ads. His sample is in PHP.
Do as I say, not as I do
I'm not doing this on my blog. Since my is hosted at weblogs.asp.net, I don't have the control to put ads in with the content, just down in sidebar. See? No, down there. Yeah. Not worth the trouble to hide them. The ads in this post are fakes, in case your highly trained eyes just filtered them out. Out of curiosity, Did anyone not notice?
