Question : Can changing the title of my pages affect my Google Adsense earnings?

Can changing the title of my pages affect my Google Adsense earnings?  Because recently my earnings per a day has dropped by almost $40 but the only thing I've done lately is change the titles of my pages.  And my traffic is at an all time high so it has nothing to do with traffic.

Answer : Can changing the title of my pages affect my Google Adsense earnings?

Yes it can.

In 2 ways:
- the title has some weight in the page ranking relevant to the words; so the page has probably now a better rank on the current title words and a lower rank on the words you have dropped.
CONSEQUENCE: changes in daily page traffic (try checking this)
- Adsense displays are related to some content analysis; if you have dropped words which are highly demanded for words less demanded, then each ad display is done at a lower bidding price.


NOTE: your earnings might also be affected by some other external sources, eg if you site was a French site related to sports, you might have had lots of demand for your site... until France was dropped out of the World Cup... and even if you are a German site and have lots of fussball-related ads... they will probably fall in 2 weeks from now.
