hello, I have link unit ads running on my site, they are giving me a very low earnings but still a good CTR. I removed them in the past (about tow months ago) for one week, and started seeing a decrease in CTR in my adsense acount. I read somewhere that if you have a high CTR showing in the Overview adsense result than the CPC goes higher overtime. I only run three ad formats, Skyscraper, Large Rectangle and Link Units. the Skyscraper and Large Rectangle CTRs is always stable but still thier CPC goes higher from time to time. the Link Units CPC is always very low. for example today I got 70 clicks only from the link unit and earned me £7, that's about 10p per a click when in Skyscraper and Large Rectangle I get more than 25p per a click sometime it goes up to 50p per a click. so only Skyscraper and Large Rectangle are giving the better earning.
should I just remove the link units off the site? that will result in my account having a low CTR. but if I remove them, the clicks witch were to go to link units will go to Skyscraper and Large Rectangle. if I leave them will the link unit's high CTR bring a higher CPC for Skyscraper and Large Rectangle overtime?
any suggestion from you guys will be appreciated.
