Best ad sizes for mobile devices in 2023
Does the size of mobile ads really matter?
Engagement with mobile devices is at an all-time high and continuing to rise with an estimated 5 billion mobile users worldwide.
Everywhere they go, people of all ages, generations, and genders are utilizing their devices, some even for several hours per day. Every day, these users are bombarded with messages, news, and social media, all of which are very distracting.
This makes it more important for mobile ads to grab people’s attention, be placed in the best digital spots for maximum visibility, and use the best banner sizes to generate the most revenue for publishers and manage campaigns effectively for advertisers.

Let’s look at some of the best mobile ad sizes for publishers in 2023 and some optimization suggestions you can start using right away:
-In 2023, the 300-250, 320-50, and 300-100 ad units are expected to gain popularity.
-The rising stars will be -36 280 and 320 480.
-Full-page web advertisements or interstitials.
-Along with optimization advice.
-The ad unit of 300250.
This medium rectangle has been the most popular banner size since Google changed their policies on mobile ad types five years ago and removed restrictions requiring 300-250 units above the fold. One of the primary reasons for its popularity is that it functions well on both desktop and mobile devices.
Because it is the first thing users see on a mobile site’s landing page, buyers tend to favor this placement. Larger mobile display ad sizes, like 300250, typically bring in more money than smaller banner sizes, like 32050.
However, placing your ads too aggressively can increase the likelihood of accidental clicks and adverse user experiences. If you are a publisher who depends on Ad Exchange or AdSense, one of Google’s monetization networks, you do not want to put yourself in danger of having your account banned.
As a result, Google’s recommendations should be followed, and only 50% of the ad should be viewable above the fold. The image below provides excellent examples of successful specifications and placements for 300250 and 30050 mobile ads.
More sizes of mobile ad units to think about.
It has been demonstrated that larger advertising formats, such as mobile interstitial ad sizes, are better at capturing the user’s attention and pay the highest CPM rates; however, publishers should exercise caution when using intrusive ad formats in 2022 on both desktop and mobile versions of their websites.
These large ad formats were born as a result of the ongoing search for innovative ways to deliver advertisements on mobile devices.
According to a recent Adpiler study, the 32050 mobile ad size is the most widely used mobile ad size. This medium banner accounts for 27% of all ad impressions. Despite its small size, it excels as an Anchor Ad.
In 2023, the 32050, 30050, and 300100 formats are expected to gain popularity. However, keep in mind the significance of the 300-250 banner to your mobile coverage.
Due to Google’s recent launch of Web Interstitials that support these three sizes, 36280 and 320480 will be the rising stars in 2023: 300×250, 320×480, 336×280.
Ads for mobile banners and how to use them.
The mobile ad ecosystem is dominated by banner ads. They are everywhere on the mobile web, and you probably have seen them in your app as well. Understanding how they function, how they can be integrated into your marketing strategy, and how to avoid common pitfalls is essential because they are not going anywhere soon.
Like desktop banner ads, mobile banner ads are only effective if the user actually notices them, which is one of the most important things to keep in mind. This entails positioning them appropriately at the appropriate time. If your customer is already focused on something else on their screen, such as a game or an email, an advertisement that appears during prime time will not be effective.
You must exercise caution when selecting the ideal location for the mobile banner advertisement on your website. You shouldn’t put it at the bottom of a page or after the last article on the page because your readers won’t be able to see it there and will likely skip over it. Instead, put it where people are most likely to see it as they scroll down your page. This way, even if they don’t click on it right away, they’ll remember seeing it later and probably return to your website because they want to see what’s underneath that advertisement.
Native Mobile Ads.
Many publishers prefer mobile native ads with the “promoted/recommended or suggested” tag because they are less intrusive and are not intended to appear sales-oriented. Publishers with a lot of pageviews benefit greatly from these ads.
Users are not bothered by these kinds of mobile ads because they blend in well with the theme and style of the content. For best results, combine them with rewarded ads and interstitial ads.
Utilize mobile video ads to maximize revenue.
-Continue optimizing your mobile ad inventory to attract advertisers with high pay rates.
-To increase engagement, use both instream and outstream mobile video ads.
-Keep your mobile video ads between 15 and 30 seconds long to get attention and sales.
Tips for optimization
1) The best way to use the mobile banner 32050 is as a docked/anchor unit. That’s when its CTR performance improves. Because it is a small ad unit, it usually performs worse than 300-250 and 320-100 units when used as a regular banner.
2) One approach to ad-blocking issues is “Scroller,” an emerging ad unit that covers the entire screen without covering the content. The report from the IAB states that this ad format has outperformed expandable banners in terms of creativity and enjoyment because it is non-intrusive (users can scroll past it).
3) The Medium Rectangle (300 x 250) banner size continues to be the most successful. Make the most of the chance to put it into action above the fold.
4) Most of the time, providers of in-banner video (IBV) favor 300 to 250. They typically offer the highest CPMs, allowing you to compete with Header Bidding to boost performance. To avoid slowing down the page, try to keep IBV to no more than two units when running.
Be careful not to overburden your users with too many interstitials during a single user session. It might turn them off, and in the future, they might never visit your website again. Keep in mind the Ad Experience Report’s guidelines if you decide to try interstitials or other intrusive ads.
5) Google suggests that the “Large Rectangle” (336 x 280) is also a popular ad size. Add it to your standard mobile ad sizes to make your ad unit flexible (e.g., 300-250 / 336-280). It has been demonstrated to perform well when embedded within text or at the conclusion of articles.
6) One advantage of mobile devices, in addition to the size of advertisements, is the location service plus. Advertising becomes more relevant to users as a result, potentially leading to more clicks. Geographic targeting will be very important if you use an ad server like Google Ad Manager. The majority of ad networks permit country-specific campaign selection.
7) Check the aesthetics of your ads. Regardless of the CPMs they promise, only the ad networks that serve high-definition creatives should be kept, and pixelated ones should be dropped. You can’t afford to give up the user experience. Non-pixelated advertisements typically have higher user engagement rates and leave a favorable impression.
8) To tighten competition, you can have multiple ad sizes compete in the same ad spot. A 300-250 spot could, for instance, serve 320-100 and 320-50. The smaller advertisements will always be aligned vertically at the top when this occurs.
9) Use Ad Networks to get the best deals. For interstitials and other mobile ad sizes, a number of advertising networks are providing flat-rate CPMs.
