Discovery ads specs examples

It’s time to take a look at some examples of Discovery Ads specs to better grasp how to use and apply them effectively.

Google Discover ad example

The last choice for where the ad goes is Google Discover. This is where people who use Android or the Google app find interesting things to read. The Raylo tech rental ad uses this place to show its fancy tech stuff and how you can get it:

Google Discover ad example

Just like the Hammonds ad, this one fits in lots of good things in a short message of 90 characters: things like free delivery, easy sign-up, and not much money each month.

Even though the picture and the words about prices are a bit different, the nice picture and short words in the ad match the page where you go. On that page, they also talk about being approved by the FCA and being on TV, which makes Raylo look good.

Gmail app Discovery ad example

Let’s look at an example from a furniture company called Hammonds. They wrote an ad with the right amount of words and talked about all the important things:

  • Get a free brochure
  • Get things at a lower price
  • No need to pay money upfront
  • You can buy stuff now and pay later
Gmail app Discovery ad example

YouTube home Discovery ad example

Look at this ad from Adidas. Adidas is a famous brand, so they don’t have to talk a lot about what they sell. This ad doesn’t say shoes, trainers, or clothes at all:

YouTube home Discovery ad example

Still, you can tell what they’re selling and who they’re selling to by looking at the cool picture and quick words. By putting this ad on the YouTube Home page, Adidas can reach the people they want and show their pictures nicely.

Best practices for Google Discovery ads specs

Excited to learn about the best practices for Google Discovery Ads specs? Here are some pro tips from our experienced Mega Digital experts in the field:

Use good pictures to make people stop scrolling

Best practices for Google Discovery ads specs
  • Use clear pictures that are at least 1200×628 pixels in size.
  • Try to take close-up pictures of something important, right in the middle of the picture, with good lighting.
  • Make sure there’s a strong difference between the things in the picture – things that are far away and close up, and use bright colors.
  • Don’t put too many words on top of the picture. If you have to, make them big and easy to read.
  • Keep the background simple.

Put up pictures that make people feel excited and want to know more

Best practices for Google Discovery ads specs
  • Show the thing you’re trying to sell or talk about.
  • Put just one thing in each picture.
  • Try not to use pictures that everyone else is using. If you do, make sure they match your brand and story.

Using words to help people understand what you’re saying

  • Give important details about what you’re selling and your brand, so people don’t have to leave the app.
  • Make sure your headlines are short, just 25 characters. Descriptions can be up to 90 characters and the name of your business can be 25 characters.
  • Write to get people to buy or do something, not just to get them to click.
  • Use friendly, everyday language.
  • Write your words in regular sentences, not all in capital letters.
