Mobile,
A bunch of different factors can influence CPC and effectivly eCPM. eCPM is just earnings per 1000 impressions and is just a simple mathematical forumla based on your earnings. CPC can be affected by the niche that you are in and also POSSIBLY by page rank (I can't find any source to confirm this but I believe I remember reading it somewhere, and it seems to make sense), so in that case CPC should increase over time (given the fact that your page rank increases).

About having an include (I'll assume you are refering to PHP), this should NOT effect adsense at all as with any server side include, the browser (client side) sees it just as if it were a straight HTML page coded normally (please correct me if I am wrong).

But anyways, considering your niche, if adsense is not scoring you well, you may want to switch to something else. An affiliate program might work, one that is targeted directly to the type of site you have. Some people do better with affiliate programs than with Adsense anyways.

Hope this helps!
God Bless!
