Chitika Channel Tips
I started using Chitika eMiniMalls a few days ago on Free Horoscope Daily, as well as on the tools pages of this site. So far so good, it seems like a very promising ad service. The ads can be contextual like Google Adsense, but I suspect you can get them to perform better by specifying keywords to bring up the product you want.
ch_queries = new Array("ipod", "camera", "dvd player", "etc."); ch_query = ch_queries[Math.floor((Math.random()*ch_queries.length))]; ch_sid = 'Channel Prefix ' + ch_query;
This will give you channel names like "Channel Prefix camera" or "Channel Prefix ipod", etc. Of course, you can change Channel Prefix to include more information on the type of ad or location of the ad.
You could also experiment with different ad colors or sizes in a similar way, and build up the ch_sid variable to include all the variables. For example:
ch_colors = new Array("red", "blue", "green"); ch_color = ch_colors[Math.floor((Math.random()*ch_queries.length))]; ch_sid = 'My Website ' + ch_color + ' ' + ch_query;
You get the picture. Of course you can do all this with Adsense too, you would just have to set up a channel manually for every color / size / location combination, then dynamically associate the combination with it's channel ID. Quite a bit more painful though.
Have fun optimizing your ads!
