I removed one of two ad blocks on one of my sites. I didn't notice any change in my revenue (at leasn not in good sense) so i puted block back. But now (for two days) i have CTR (i don't get it) and eCPM (of removed add) extremly low. If anyone has any ideas i'm listening. PS: My english sux. for example: i removed bottom of the page add here: "http://www.beautiesDB.org/index.php?linked=1&event=browseNAME&name=Ali Landry" ^^Oh it was the sam block as on top i now removed it becouse it's bad performance. Will be greatful for any tips.
Google gets a bit confused when blocks go in and out and in and out and in and out. LOL I dunno. I only use one block on my sites. It seems to get higher click value. Col
Whether that change in CTR means anything is dependent also on the amount of visitors you get. If you get below 1000 visitors a day, I would not jump to conclusions on day to day changes.
