Display Advertising: How to Use Banner Ads to Build Brand Awareness

In the age of ad blockers and banner blindness, is display advertising still worth it? For many businesses, the answer is yes — but only when used for the right goals. Understanding where display ads fit in your marketing mix is the key to making them valuable rather than wasteful.

What Are Display Ads?

Display ads are visual banner advertisements that appear across websites, apps, and YouTube. Unlike search ads (which appear when someone actively searches for something), display ads appear on websites relevant to your target audience or to people who match your demographic and behavioral criteria — even when they're not actively looking for your product.

The Google Display Network (GDN) reaches over 90% of internet users across 2 million websites and apps. This massive reach makes display advertising effective for awareness campaigns.

When Display Ads Make Sense

Brand awareness: Display ads excel at exposing your brand to a large audience. CPM (cost per thousand impressions) on GDN is typically very low — Rs. 10–50 per 1,000 impressions. You can put your brand in front of a targeted audience at minimal cost, building recognition before they're actively searching for your service.

Retargeting: This is where display ads deliver the strongest ROI. Showing ads specifically to people who have already visited your website dramatically outperforms cold audience targeting. Someone who visited your pricing page is much more likely to click an ad for your service than a random internet user. Retargeting keeps your brand visible to warm prospects during the consideration phase.

Launching a new product or service: When you need to quickly build awareness for something new, a display campaign can spread the message across thousands of websites rapidly.

Types of Display Ad Creative

Responsive Display Ads: Google's recommended format. You upload headlines, descriptions, logos, and images, and Google automatically assembles combinations that fit different ad slots. Simple to create, performs well across the network.

Custom HTML5 Ads: Animated banner ads built in HTML5. More engaging than static images but require design skills or a designer. Generally perform better than static creatives for awareness campaigns.

Standard banner sizes: 300×250 (medium rectangle, most common), 728×90 (leaderboard), 300×600 (half page), 320×50 (mobile banner). If creating custom creative, at minimum produce the 300×250 and 728×90 sizes.

Targeting Options

Contextual targeting: Ads appear on websites whose content matches your keywords or topics. A digital marketing agency might target websites about business, entrepreneurship, and marketing.

Audience targeting: Target people based on their interests, demographics, and online behavior (in-market audiences who are actively researching your category).

Remarketing/Retargeting: Target previous website visitors. Segment them by pages visited for more personalized ad messaging.

Placement targeting: Manually select specific websites where you want your ads to appear.

Setting Realistic Expectations

Display ads have very low click-through rates — typically 0.05–0.3%. Don't judge display campaigns by clicks alone. Measure reach, frequency (how many times your target audience sees your ad), and downstream impact on website direct traffic and branded searches. These "view-through" effects are real even when no one clicks the ad directly.

Use display advertising as a complement to search and social ads, not a replacement. Its strength is reach and visibility at scale; direct response is better handled by search campaigns.
