I know it's against the TOS to disclose AdSense statistics, but I just want to comment I've noticed enormous drops in eCPM rates over this past month. Just wondering if this is across the board? Or is it just me? CTRs are appearing consistant.

This thread shows the common problem of sudden AdSense revenue swings that don't always track with traffic. Contributors such as , and have already described the frustration. The steps below focus on practical, evidence-based checks and short-term actions you can run right now to find the root cause and reduce future risk.

Quick diagnostic checklist:

  • Run split reports in AdSense and your analytics: compare estimated earnings/Page RPM, CPC, impressions and clicks by ad unit, country and device for the period before vs during the drop. A stable CTR with lower revenue usually indicates lower bidder demand or CPC declines.
  • Segment traffic by source and landing page. A sudden shift toward low-commercial-intent or bot/referral traffic can reduce eCPM even when pageviews rise.
  • Check AdSense messages, policy center and any invalid-traffic notices. Verify ads.txt and any recent consent/CMP changes that might stop bidders from seeing impressions.
  • Review recent code/site changes (new plugins, lazy-loading, ad code edits). Small template changes can break ad requests or hurt viewability.
  • Audit the Ad Review Center and category/advertiser blocks—overblocking reduces auction competition.
  • Run one controlled A/B test at a time (single ad size or position) and collect at least a week of business-cycle data.
  • If you see account-wide anomalies or invalid-traffic flags, capture screenshots and contact AdSense support.

Short-term mitigation and longer-term planning: if CPC fell, prioritize pages with higher commercial intent for direct offers or targeted affiliate placements and create custom channels for premium pages; if CTR fell, improve above-the-fold viewability and user experience rather than cramming more units. Do small tests, use conservative forecasts (treat single-month drops as provisional), and build a cash buffer.

Diversify revenue: direct sponsorships, memberships, product/services, targeted affiliate offers and measured tests with other monetization partners. As explored alternatives and suggested looking beyond one network, validate each new channel on a small slice of traffic before committing.

Apparently they're back to normal levels again.

At least they're back to normal for me. :cool:

Are they still low for you?

I saw a 60% drop from about 3 Feb right through to around 2 March. Things seem to have gone back up to the initial levels (for the last week at least :D). I know of two completely unrelated adsense advertisers who saw the same thing. Too weird.

Eek, Mark! 60% is quite the load to lose. Unfortunately, my CTRs are now suffering, but my pageviews are up. These last few months have been fluctuating by so much, I really can't even bet on Google to come through for me with any even near-guestimate amount of money. It's really hard when my monthly budget really heavily relies on AdSense. :(

Same here. My revenue the past month is half of what it normally is with the same amount of traffic and clicks. I just signed up for Commission Junction and Amazon.

This thread is from February 2005 btw. Never had much luck with CJ. Perhaps try ad networks such as ValueClick or Tribal Fusion?

I actually signed up with CJ through Sirius Satellite radio because I'm a big Howard Stern fan. You can listen to I get $ .50 for each person who signs up for the Sirius Internet Radio free trial. If they buy a radio I get $20. Not bad.

I'm also doing well with Amazon by featureing products which pertain to my site.
