Impressions are "Too Low".

A troubleshooting guide to help when the number of impressions recorded in the Revive Adserver statistics don't align with the number of impressions expected.

 

...

Symptoms

The number of impressions recorded in Revive Adserver are (much) lower than the number of page views for the website you're running ads on.

Troubleshooting Process

Step 1: Upgrade Revive Adserver

Prior to Revive Adserver 3.1.0, if no banner was shown, then no impression was logged. However, with the release of Revive Adserver 3.1.0, "blank" impressions are now recorded, so, you may find that upgrading to this version or later resolves the issue. If it does, though, you may want to consider adding Remnant Campaigns with unrestricted banners to ensure that users always see a banner, or setting default house banners.

Step 2: Check Expectations

Before you start to dig into the issue, it's worth double checking that your expectation on the number of impressions you're expecting to see recorded in Revive Adserver are correct.

...

Once you've double checked that the number of impressions you're expecting to see recorded in Revive Adserver is correct, then move on to the next step.

Step 3: Check for "Faulty" Zone(s)

Even if you're checked on your site for pages or site sections where banners may be obviously missing, check through the statistics in Revive Adserver by zone. Are there any zones that appear to be obviously low on impressions compared with what you'd expect?

If so, it would be worth investigating where those zones are supposed to be displayed on your site, and double check that they are where they should be, and that they are working.

Step 4: Check Requests vs. Impressions

If you are not logging requests as well as impressions, then turn on request logging, and compare the number of requests to the number of impressions.

You may need to consider upgrading your servers or hosting, or look to speak to your ad network provider about their load times.

Step 5: Consider Page Load Time from Analytics

Review the page load time recorded by your site's analytics tool. Taking more than a couple of seconds on average? Got any banners near the bottom of the page?

...

You may need to consider upgrading your servers or hosting.

Step 6: Review Top vs. Bottom Zone Impressions

If you're page analytics tool doesn't have page load times, then you could possibly review the number of impressions for zones that are located near the top of your pages vs. the impressions for zones that are located near the bottom of your pages.

You may need to consider upgrading your servers or hosting.

Step 7: Check the Block Banner Logging Settings

Revive Adserver has a number of options to prevent the logging of banner statistics (including the logging of impressions), based on IP address and/or user-agent string.

Check to see if these have been enabled - if so, then they will naturally result in a lower number of impressions being recorded vs. page views.

Step 8: Check for Adblockers

Finally, Adblockers, depending on settings, may allow banners to be displayed, but block the logging of impressions.
