I've been trying to look for some information on this for a little while and I'm not finding any. I guess the only way to know for certain is to remove yourself from AdShare for a long enough time and see what happens, but my guess is you won't see any significant changes.
Yes your overall CTR will decrease.
Since CTR = clicks / pageviews
and you are not getting clicks from here, but you are getting page views your CTR naturally goes down.
The question is does that matter at all?
It only matters if your average price per click is based in any degree on CTR. That's what I've been trying to find out without luck so far. If anyone knows if average price per click is tied to CTR please share that info.
Let me try an example. Let's say you get 100 impressions on your ads and get a total of 5 clicks (CTR = 5%) and lets say each click pays you $0.20 so you make a total of $1.
Now lets say I have on my site something similar to AdShare and you join. And lets say you also get 100 impressions on the ads on my site, but no one clicks so sadly you make $0 on my site.
So overall between the two sites you've gotten 200 impressions, but still only 5 clicks. Your CTR is now 2.5% so it is lower.
The question is are you still averaging $0.20 for each of those 5 clicks. If you are then you still made the same $1 and having your ads on my site had no effect on how much money you made. If however the average price per click is somehow tied to your overall CTR and is reduced because your CTR is also reduced then you would be making less money.
I haven't found an answer to whether or not the money you earn from each click is at all dependent on your overall CTR. I would assume the info is out there and it's an easy enough test to try. Remove ads from all your under performing pages and see if you make more money.
adrian is this making sense? It does to me, but I may not be explaining it well.
I don't have a real answer for you since I don't have the crucial piece of information, but I'll gladly keep looking and if I still can't find anything perhaps I'll take my own advice and remove ads from some under performing pages on my site or even drop the AdShare for a month and see what happens.
The reason I'm not sure how much it will affect you one way or the other is because I suspect you only get so many impressions from being in the AdShare program. You would need to get a lot more impressions on your ads here than on the ones from your other sites to make the numbers here significant in the overall calculations.
