TOP-5 Google Ads Advertising Formats: How to Choose, Adapt, and Test

When you place banner ads on the Display Network, you'll need to choose the right image size. Adjusting and optimizing your ads will help you improve your ad campaign results and manage your advertising budget effectively.

Each format has its own purpose and intended use. A single format is not the best option if you plan to host on many sites, because for each of them the creative needs to be adapted. Various ad formats are available on electronic platforms. Choosing the wrong size will limit your campaign reach. Over the past few years, the CTR of Google Ads banner advertising has almost halved (from 0.80% to 0.47% between 2019 and 2021). CTR formats are different, and you need to understand which format gets more clicks. For example, 300x250 ads receive more clicks than 728x90 or 160x600 banners.

In addition, ad-blocking services installed in users' browser settings — Adblock Plus, Brave Browser, Opera VPN, and NordVPN — can affect campaign performance. These systems have learned to track and block the most popular ad sizes (300x250 and 728x90), but may miss other options. Therefore, you need to look for an alternative with at least one click, prepare and optimize as many formats as possible.
