How to create effective display ads in Google Ads?

ROI answers

Google Display Ads work by showing visual advertisements across a vast network of websites, apps, and Google properties to reach potential customers based on their interests, demographics, and online behaviour. As of early 2026, Google’s machine learning plays a significant role in optimising ad delivery and performance.

  • Responsive Display Ads: Current systems include the ability to upload multiple headlines, descriptions, images, and logos; Google automatically tests combinations to find the most effective variations.
  • Audience Targeting: Leverage detailed demographic targeting, affinity audiences (based on interests), in-market audiences (actively researching products), and custom audiences (based on your customer data).
  • Remarketing Lists for Display Ads (RLDSA): Re-engage website visitors who haven’t converted, showing them tailored ads based on the pages they viewed.
  • Automated Bidding: Google Ads now features ‘Performance Max’ campaigns, utilising AI to optimise bids across all Google channels, including Display, to maximise conversions.

In 2026, Australian businesses must also be mindful of the Australian Consumer Law when crafting ad copy, ensuring claims are accurate and not misleading. Data privacy is also paramount; Google’s Privacy Sandbox initiatives are increasingly important for compliant targeting, and understanding these changes is crucial for effective campaigns. Furthermore, ensuring your landing pages are mobile-optimised is vital, as mobile traffic consistently accounts for a significant portion of Australian internet usage.
