Hi Am new to adsense but my url has eCPM of $1000 What does it mean. Would I earn this figure if I have 1000 page visitors or views
Your eCPM is your 'estimated' amount that you would earn if 1000 vistors visited your page and clicked on your ads at the current click rate. For example if 1 vistor visited your page and clicked on your ad your eCPM would be a large number like $1000 but if 50 vistors visted your page and only 1 of them clicked your ad your eCPM would be a lower number. Hope this helps.
Yes, the eCPM is somewhat misleading because it is a larger number, but that is correct, it is your earnings per 1K impressions.
