Agree with all your points and that’s exactly what I was expecting, but in your first response you said caching does decrease ad impressions.

The more you cache a page, the more you’d lose in ads.

Thanks for helping out!

I did ask one of the ad networks, and their answer (just liked I’d expect) was that their ads aren’t served locally via my site obviously so my plugin can’t cache them. I tend to believe that, b/c these are major ad networks and I doubt I’m the only one using W3C with an ad network.

Might have not been clear on this earlier, but everything was totally normal when APC page caching was selected, just disk enhanced somehow reduces ad impressions considerably. So I assume this has nothing to do with how they count visitors.

Another guess: maybe disk enhanced page caching changes they way the different pieces on my site are pulled in and “de-prioritizes” the javascript ad tags so the site loads quickly but not all of the ad tags are fully loaded before a user is onto the next page?

Thanks again!

Thanks for your feedback again, but would really love to get any insight into my questions though. Why would caching affect adserving?

Hoping someone else can chime in, b/c I don’t understand why caching would do this. All major online publisher (I even work for one) use page caching I assume, I doubt they would let this affect their ad impressions served.

Based on my Pingdom tools link, can the issue be that my site now loads very fast and the ad tags are loading towards the end so many users are already on the next page before the ads have had time to load?

Thanks again!

Thanks for the feedback. I updated the pingdom link above in my original post.

This is the first time I’m hearing that I lose ad impressions when caching a page. Isn’t that the whole point of using W3?
