What could be possible reason of decrease in eCPM from ~$1 to 0.25?

Hello everyone,

I am very new to here and seeking experts advice

My normal eCPM (average of last 3 months) is ~$0.90 - 1.00 and went high for few days to $2.00 too. All of sudden it kept reducing and now fall down to 0.25. Anybody can give me any clues for that? Here are few updates to the site as of I know:

- Moved from DreamHost to Alnitech (IP is clean/non-spamming)
- Added some Facebook related plugins for comments, chat etc.,
- Pageviews are increasing and now stable at around 120K-150K per day
- Installed some caching plugins for wordpress (WP-Super-cache)

And yes, No Alerts/Warning from Google since my account is active (About 9 months)

Any hints?

Thanks a ton in advance,

Ashvin

 

If you mention your blog/site url here, someone can help you out.

 

all of changes you have mentioned here are not the reason of low eCPM, IMO.

 

It will take around 10-15 days to get back due to hosting change

 

Sometimes, it might be a drop in advertisers in that niche.

 

Adword users on your niche probably has something to do with it. Lack of advertisers or changing target keywords or even lower bids could take effects.
