Does Google display ad size matter?

When configuring your advertising campaign with Google, choosing the size of the image is important. Websites that publish your ad themselves allocate a special place for this. Therefore, if the site has a place at the top of the page suitable for the banner format, you cannot place a square there. So, the quality, coverage, and attractiveness of your advertisement will be drastically reduced and quite uninteresting for visitors to the site.

When placing Google display campaigns, you need to consider what image to use. If you choose the wrong size and format of the advertising image, it will drastically reduce the scope and effectiveness of your advertisement.

Undoubtedly the same image size would be a convenient plus for all advertising formats. But, certain suitable advertising formats get more clicks and user transitions than analogs.

Choosing the right Google ad size is important because banner advertising does not always get a high CTR. The correct format will allow you not to waste your advertising budget.

Moreover, some sites only host small-resolution images, and some advertise higher-size advertisements. So you can’t just choose one or two sizes.

However, there is a division by device in advertising sizes. In this case, you should prepare an advertisement in size, for example, for a computer and mobile device. After all, if you optimize only one size of advertising, and it will get on the device, where the advertising of a given size is not played, you just lose your budget and potential consumers.

Then it is important to understand the advertising size and be able to choose them correctly. You should optimize a large enough number of advertisements to increase the visibility of your brand, product, or service.
