In-article ad survey: 300x250 revisited

The research question

This report revisited the static 300 × 250 ad placed between paragraphs — a format the Committee’s 2021 in-article and in-gallery survey found acceptable overall but flagged as a borderline case pending further research. This report re-tests the format with a larger sample and a more realistic web experience, to determine whether it should be added to the Standard.

Method and sample

3,004 ad-blocking participants recruited via Dynata from the US, Germany and France (1,001 / 1,004 / 999 after quality-check removals), rating a 300 × 250 in-content ad shown within a long-scroll article alongside a top banner and a right-rail ad.

Main findings

• —In this 2024 replication, the 300 × 250 ad was not perceived as highly disruptive, annoying, or intrusive. Younger participants still rated it somewhat more disruptive than older participants, but the gap was no longer statistically significant, and all ratings — for the ad itself and for the overall ad experience — stayed below the 35% disruptiveness threshold set out in the AAC’s bylaws.
• —The report’s own conclusion is that this replication supports including the 300 × 250 in-content ad in the Acceptable Ads Standard.
• —The research was conducted in February 2024 and presented to the Committee on June 24, 2024, when it was accepted. The 30-day probationary period ended on July 24, 2024.
• —In the original 2021 study, this same format cleared the 35% threshold overall, but younger adults (16–44) rated it significantly more disruptive than older adults (45+), and the Committee did not add it to the Standard at that time, pending further research — the gap this 2024 report was designed to close.

These findings are the report’s own results and conclusion, not by themselves a Committee decision. The Committee separately reviewed and accepted the proposal, as described above.

Limitations and context

• —Recall of the 300 × 250 ad was low in this study: 36% of younger participants and 27% of older participants recalled seeing it, well below the 2021 study’s 86% and 70%. The report suggests a possible explanation: this study’s more realistic web experience included in-article images that may have made the ad less noticeable, unlike the 2021 study’s mock pages, which had none. Participants who did not recall the ad rated it less disruptive than those who did.
• —The study environment remains artificial and may not fully reflect real browsing, where users can encounter more ads and effects may accumulate across a session.
• —Engagement with the article content could not be directly measured; comprehension-question results and average time on page suggest engagement but do not confirm it.
