Google Display Network Ad Specs

Google Display Network provides a medium for advertisers to place their ads on websites where they can target their audience. It’s easy to use if one knows the fundamentals. But what’s in it for publishers if you ask?

For publishers, on whose websites these ads are placed, it’s better to know about the ad specifications and how they ultimately affect the overall look and feel of the website. If you (publisher) use AdSense to show ads, then you are a part of the Google network.

Hence, it’s important to know about both sides of the story and how ads specs affect your revenue generation. So without further ado, let’s start with Google Display Network ad specs and how can publishers leverage that information to make profit.

1. What Are Google Display Ad Sizes?

This is something that worries both publishers and advertisers. Nobody actually knows which ad size is ideal. And there’s nothing fixed too.
It starts with the publishers making ad spaces (called digital inventory) on their web pages. Next, the advertisers look at the available spaces and design their ads accordingly. Here are some standard ad sizes supported:

Ad SizeNameSpecs
250x250SquareGenerally placed on left or right sidebar of the page
200x200Small SquareGenerally placed on left or right sidebar of the page
468x60BannerPlaced between articles or between breaks
234x60Half BannerPlaced between articles or between breaks
728x90LeaderboardFeatured on top of a webpage near the logo
300x250Inline RectanglePlaced within the content or at left-right sides of pages
336x280Large RectanglePlaced within the content or at left-right sides of pages
120x600SkyscraperGenerally placed among sidebars and requires huge vertical space
160x600Wide SkyscraperGenerally placed among the sidebars and requires huge vertical space
300x600Half PageTakes up almost half of the webpage’ great for awareness/branding campaigns
970x90Large LeaderboardCovers end to end horizontal space; generally placed at the top of page or between breaks
320x50Mobile LeaderboardPlaced at the end of a webpage on mobile devices

The ideal ad size depends on the website type and advertisers’ requirements. However, the top performing Google network ad sizes are inline rectangle (300×250), leaderboard (728×90), wide skyscraper (160×600), and mobile leaderboard (300×600). All these and 180×150 (small rectangle) are display ad standard sizes set by IAB.

For publishers, it’s recommended to go with standard ad sizes, as they are proven to drive better results. Also, ad spaces should be allotted in a way that they don’t block the main content. Otherwise, publishers would lose visitors and hence the interested advertisers.

2. Which Ad Format To Choose?

Google display advertisement mainly deal in three types: static, animated, and interactive.

Static ads are images with texts in JPG, PNG and GIF (one loop) format. Animated ads can be of both GIF or SWF format. However, interactive ads, which need visitors’ involvement like hover on the ads, can only be uploaded in SWF format.

Choosing the ad type and format is an important part of the campaign. Animation and motion works fine to get visitors’ attention. Though, too much popping animation can annoy the visitors.

This is the reason, most publishers stick with static ads that have least chances of annoying the visitors. Furthermore, too many ads with loads of animation can affect page load time that ultimately affects the revenue too.

3. What Are Display Ad Content Specs For Publishers To Know?

Google Display Network has some strict rules when it comes placing an ad to the websites. Here’re some general policies that Google (and publishers) ask advertisers need to follow:

  • The image should be clear. A blurry or pixelated image is rejected right away.
  • For advertisers, it’s advised to create ads resembling their brand or website. If visitors click on the ad, they should be redirected to a familiar web page.
  • Advertisers are recommended not to imitate publisher’s webpage. Banner ads should be designed in the advertised brand’s persona.
  • Do not create fake promising or hoax ads to trick visitors to click on them. Also, mimicking system warning or operating system error message to get clicks is not an acceptable method to run ad campaigns.

If you look carefully, Google ads policy is designed to give a smooth visitors’ experience. This is obviously because visitors are the most important when it comes to revenue generation. Just like publishers, Google also doesn’t want to annoy visitors and hence these policies are formulated.

4. Is There Any Restricted Content For Ads?

There are certain things that can’t be shown in an ad because of being sensitive. Here’s some content type that Google doesn’t allow:

  • Violent content or any text or image posing threat against an organization, person, group of people or a protected group distinguished by race or ethnic origin, color, national origin, religion, disability, sex, age, veteran status, sexual orientation, or gender identity.
  • Alcoholic beverages, illegal drugs, and illegal chemical or their use,
  • Adult content including escort services or profane content.
  • Gambling (online or offline) or any services related to the same.
  • Ads infected with virus, malware or similar threats.

Also, using call-to-action is a good method to get leads. Generally, ads with text like ‘learn more!, shop now>>, get details…’ have a better chances of conversion.

Testing bears better results. Just like any other campaign, ads also are need to be tested in terms of format, type, color, size, position, design, and more. Not just for advertisers, publishers are also advised to run test ads. Google AdSense provides option to create test ad units and monitor them.
Finally, publishers need to know look and feel of the ads that affect ad viewability. A good viewability score improves ad revenue. And a nicely designed ad has a chances of good click-through rate and better CPM. All the insights kept in mind by publishers help them attract more advertisers and begin the ad revenue cycle again.
