I have two almost identical music sites:
www.musictodownload.eu
www.freemusictodownload.eu
They always have had very similar AdSense CTR and Revenues.
Few weeks ago I started to exchange links. I have been offering adding link on
www.musictodownload.eu (in Links) in turn of placing link to my other site
www.freemusictodownload.eu.
Since I have been doing it, I have noticed dramatically drop of my CTR for
www.musictodownload.eu. It was earlier about 30% and now (for few weeks) is about 5%. Of course I have more impressions for
www.freemusictodownload.eu and almost the same CTR as earlier.
Why have dropped my CTR for
www.musictodownload.eu? Could you help me?
Thank you!
