Medium Rectangle Ads - A Flexible Monetization Tool For App Publishers

Medium Rectangle Ads - A Flexible Monetization Tool For App Publishers

Medium rectangle ads are one of the most common mobile ad formats in use today — and for good reason. These mid-size banners are a major revenue driver for publishers and advertisers alike.

Medium rectangle ads, or MRECs as they’re known colloquially, make up 40% of all banner ads that appear on the web, and constitute an even larger portion on mobile. That’s because MRECs are incredibly effective at balancing the goals of both publishers and advertisers thanks in no small part to standardization practices put in place by industry bodies like the Interactive Advertising Bureau (IAB).

These banners are large enough to capture user attention via in-feed placements, but small enough to keep them engaged in the app experience. They’re especially powerful in media apps, but can also be deployed effectively in most other app categories.

At Vungle, we work with app publishers across every category. Our partners continuously uncover new use cases for MREC ads, demonstrating the versatility of the format. Don’t let its size mislead you. With video, static, and GIF functionality, MRECs see high engagement, particularly when placed effectively.

In this post, we’ll take a look at how MRECs can enhance your monetization efforts, including how much revenue you can expect from a successful deployment. Let’s jump in!

Let’s Get Started

What are medium rectangle ads?

What are medium rectangle ads?

Medium rectangle ads are medium-format ad units sized between mobile banners and full-screen interstitials. At this scale, advertisers can include more details or creative elements without disrupting the user experience.

MRECs are best placed within apps and pages that users can scroll through, such as lists, social media feeds, and blog posts. Their integration into dynamic UX elements results in higher levels of engagement than other static placements that are typically pinned to the top or bottom of an interface. They are also very effective in content streaming apps when placed at natural breaks in the content flow. Publishers can also use MRECs at any point where they may have otherwise used an interstitial, such as when users complete an order in an ecommerce app or a level in a mobile game.

How much do medium rectangle ads make?

As a higher performing subcategory of display ads, medium rectangle ads typically generate between $0.80 and $2.00 for every 1,000 impressions. MRECs represent a moderate CPM compared to other ad formats, but they have several crucial benefits. They are as unobtrusive as other banner ads, but also meet a common standard as defined by the IAB. MREC ads are cost-effective for advertisers looking to buy on a CPM to drive brand awareness.

Why use medium rectangle ads?

Medium rectangle ads are similar to other mobile banner ads, but they also have a few unique benefits of their own. Most notably, MRECs are low cost and can be implemented at high visibility points in the user experience, protecting them from the effects of banner blindness — the phenomenon where users ignore overfamiliar ad placements. In most cases, MREC placements also support video campaigns. Combined, this allows them to generate up to 10 times higher average CVRs than traditional banners.

Let’s take a closer look at the benefits of MRECs for advertisers and publishers:
