In March 2016, the IAB provided a primer for publishers covering the main variables of how to improve ad viewability. You will find a condensed list of best practices below.
The primer suggests that it is the publisher’s responsibility to stay on the cutting edge of technological advances in viewability measurement. Furthermore, publishers should guide agency/advertisers in new findings on viewability measurement tools and other viewability trends. The IAB primer states, “publishers would benefit from educating advertisers and agencies on measurement, latency and industry trends.”
Publishers know their advertising opportunities best and should be setting the example on their sites for viewability standards, make-good impressions, and which viewability measurement tool they are going to accept for billing on vCPM. Publishers should be taking the lead on viewability issues. The IAB Primer says, “When publishers create the necessary changes, the marketplace does respond and the rewards do follow.”
Publishers are also urged to be transparent with their metrics so that both sides can benefit; this can be accomplished by closely partnering with advertiser/agencies.
IAB’s Best Practices on Viewability for Publishers:
- Have your own viewability measurement tool for your site
- Conduct a site-audit and gather baseline metrics for your ad units
- Be wary of “out-of-focus” tabs/windows, especially with video
- Benchmark latency and develop a latency improvement plan (latency is how long your ads take to fully load)
- Lazy Load below-the-fold ads (they should only load when someone gets to that place on the page)
- Limit creative weights, charge more for heavy assets
- Serve ads directly rather than through 3rd party if you can
- Adjust ad-refresh time, experiment with it, it may improve viewability
- Continuously educate advertisers & agencies on measurement, latency & industry trends – maintain transparency
- “Certify a limited set of trusted vendors for 3rd party billing,” if advertisers or agencies choose a vendor outside the trusted list, they should be within a 10% variance
- Monitor the vendor marketplace and MRC guidelines
- Continuously monitor measurement rates from different vendors – report back to vendor and MRC
