eCPM: earnings/1000 views (1$ eCPM means you will earn 1$ for 1000 views) CTR: number of clicks/number of views [%] estimated earnings are just estimated earnings
Then how is my keyword for the site related to the adsense ? Like my keyword's advertiser CPC is lets say 10$, and I get all organic certificate, how much I will earn ? Can you give this idea ?
If you write about games, adsense ads will be related to 'games' keywords. Don't know how much will you earn that can't be calculated. Maybe nothing maybe 10000$
eCPM = earn per CPM CTR = like a rate, how many percent of users click on your ads per 1000 hope it helps
