Darren Rowse at Problogger has posted some great tips on How to Grow Search Engine Traffic to Your Blog. How does this relate to earning revenue with Chitika? Chitika|Premium ad units are specifically designed to display when, among other behaviors, your visitors are coming from a search engine; so it only makes sense that you’ll earn good revenue from Premium ad units if you have a good amount of search engine traffic. Since we already know that search engine traffic is more likely to convert to ad clicks than non-search traffic (see our Google/Digg traffic study here), increasing your search engine traffic will give your Premium ads more exposure and, therefore, increase your revenue. This winning combination yields a high eCPM for many of our publishers already.
