Display Ads
Display ads are image or banner advertisements shown on websites across the Google Display Network, targeting audiences by interest, behaviour or context.
Display ads are visual advertisements, typically images or banners, shown to users while they are browsing websites in Google’s Display Network or other ad networks, rather than when they are actively searching.
What Display Ad Means in Marketing
Most advertising reaches people who were not looking for it. Display ads are the digital equivalent of a billboard: the user is doing something else, and the ad appears in their environment. On the web, that environment is any of the millions of websites and apps that carry programmatic advertising.
Display ads serve awareness and retargeting goals. For awareness, they introduce a brand or product to audiences who match a target profile but have not yet searched for what the brand offers. For retargeting, they re-engage users who have already visited a website, keeping the brand visible through the remainder of the purchase consideration period.
The Google Display Network is the dominant platform for display advertising, reaching users across websites, news portals, blogs and apps. Display campaigns run through Google Ads.
How Display Ad Works
The process separates into three decisions: targeting, creative and bidding.
Targeting determines who sees the ad. Audience-based targeting uses Google’s data on user interests and behaviours to reach relevant people across unrelated sites. Contextual targeting shows ads on pages whose content matches specified topics or keywords. Retargeting shows ads to users who have previously visited your website.
Creative is the visual ad itself. Display ads range from static images to animated HTML5 banners. Responsive Display Ads are the current standard: the advertiser uploads multiple headlines, descriptions and image assets, and Google automatically assembles and tests combinations across different placement sizes.
Bidding can optimise for clicks, impressions, or conversions. Most display campaigns targeting awareness use cost-per-mille (CPM) bidding. Retargeting campaigns often use target CPA or maximise conversions, since the audience is already warm.
Display Ad Example
An online furniture retailer runs two display campaigns. The first targets users in the “home decor” in-market audience who have not yet visited the site, showing aspirational room setting images to build brand awareness. The second targets users who browsed the sofa category but did not purchase, showing the specific products they viewed with a discount code. The awareness campaign builds reach; the retargeting campaign recovers abandoning users.
Why Display Ad Matters for Marketers
Display advertising expands reach beyond the search bar. It is the tool for building brand recognition among audiences who are not yet actively looking, and for staying visible to potential customers through a long consideration cycle.
Frequently Asked Questions
What is the difference between display ads and search ads?
Search ads appear when a user actively searches for a keyword and has declared intent. Display ads appear as the user browses other websites and are not triggered by a specific search. Search ads capture existing demand. Display ads create awareness or re-engage audiences who have previously visited your site. The two serve different purposes in the funnel: display works for awareness and retargeting, while search works for intent-driven conversion.
What targeting options are available for display ads?
Display ads can target by audience, context, or both. Audience targeting includes interest categories (affinity audiences), active research signals (in-market audiences), demographic segments, and custom audience lists built from your own customer data or website visitors. Contextual targeting shows ads on pages whose content matches topics or keywords you specify. Placement targeting lets you choose specific websites where your ad should appear. Combining audience and contextual targeting focuses spend on users most likely to be interested.
What sizes should I create for display ads?
The most widely supported and highest-impression sizes are 300x250 (medium rectangle), 728x90 (leaderboard) and 160x600 (wide skyscraper). For mobile, 320x50 and 300x250 are the dominant formats. Responsive Display Ads allow you to upload image and text assets and let Google automatically generate ads in the correct sizes for each placement. Starting with responsive display ads is the most efficient approach for most advertisers; custom-sized ads are worth producing for specific high-value placements.
