Ad Creative Best Practices: How to Design Ads That Actually Get Clicked

You can have flawless targeting, a competitive bid, and an ideal audience — and still get dismal results. The reason is almost always the same: weak ad creative. In programmatic advertising, your creative is the bridge between your budget and your conversions, and how you design it determines whether users engage or scroll past. In this post, we'll walk through the core principles of effective ad creative so you can get more out of every campaign you run on Squren.

Why Ad Creative Matters More Than You Think

In a real-time bidding environment, your ad is served to the right person at the right moment — but you still have a fraction of a second to earn their attention. Creative quality directly affects your click-through rate (CTR), your conversion rate, and ultimately your return on investment.

A poorly designed ad wastes your impressions. A well-designed one multiplies the impact of everything else you've optimized — your targeting, your bids, your landing page. If you're not seeing the results you expect from your campaigns, your creative is often the fastest lever to pull.

1. Match the Creative to the Ad Format

Different ad formats have different user experiences, and your creative should be designed with that in mind.

  • Banner ads are typically viewed in a content context, so they need to stand out visually without feeling out of place. Bold colors, clear headlines, and a single call to action (CTA) work best. See our guide on banner ads best practices for format-specific tips.
  • Popunder ads appear behind the browser window and are seen after a user finishes their session. The creative doesn't need to compete for immediate attention — it should be clear, self-explanatory, and persuasive on its own. A strong headline and a compelling offer go a long way.
  • IM floater ads appear as floating overlays and tend to get high visibility. Make sure the message is short and the CTA is immediately obvious.
  • Interstitial ads take over the full screen briefly, so you have more real estate — use it to tell a short story or present an offer that justifies the interruption.
  • Mobile redirect ads serve users on mobile devices and redirect to a landing page. The creative experience is the landing page itself, so the visual design and load speed of that page matter enormously.

When your creative is built specifically for its format, it performs better. Generic creatives designed for one format rarely translate well to others.

2. Lead With a Clear Value Proposition

Users don't read ads — they scan them. Your creative has roughly two to three seconds to communicate why someone should click. That means your core message needs to be front and center, not buried in fine print.

Ask yourself: what is the one thing I want this person to understand immediately? That answer should be your headline or primary visual element. Whether it's a discount, a product benefit, a solution to a problem, or a curiosity-driving question — lead with it.

Avoid trying to communicate too much in a single ad. One strong message beats three weak ones every time.

3. Use a Strong, Action-Oriented CTA

Your call to action tells the user exactly what to do next. Weak CTAs like "Click here" or "Learn more" are vague and easy to ignore. Stronger alternatives include:

  • "Get Your Free Trial"
  • "Claim This Offer"
  • "Start Saving Today"
  • "See How It Works"

The best CTAs create a sense of benefit or urgency without feeling like a hard sell. They match the emotional tone of the rest of the ad and give users a reason to act now rather than later.

Make the CTA button visually distinct — use a contrasting color that stands out from the background so it's impossible to miss.

4. Keep Visual Design Clean and Focused

Cluttered ads confuse users and reduce CTR. Every element in your creative — the headline, image, CTA, logo — should serve a clear purpose. If it doesn't add to the message, remove it.

A few design principles worth following:

  • High contrast: Make sure text is readable against the background. Dark text on light backgrounds or light text on dark backgrounds works reliably.
  • White space: Don't be afraid of empty space. It makes the ad feel less overwhelming and draws the eye to what matters.
  • Brand consistency: Use your brand colors, fonts, and logo so users associate the ad with your brand, even if they don't click immediately.
  • Relevant imagery: Use images that reinforce your message. A product shot, a human face, or a bold graphic all outperform generic stock imagery.

5. Optimize for Mobile Devices

A large share of ad traffic comes from mobile devices, and creatives that aren't mobile-optimized lose out on a significant portion of potential clicks. Make sure:

  • Text is large enough to read on a small screen
  • CTAs are large enough to tap with a finger
  • Images scale properly without cropping important elements
  • Landing pages load quickly on mobile connections

If you're running campaigns across both desktop and mobile, consider creating separate creatives for each rather than relying on a one-size-fits-all design.

6. Test Multiple Variations

Even experienced creative teams can't always predict what will resonate with a given audience. That's why testing is essential. Run two or more versions of your creative simultaneously and let the data tell you which performs better.

You might test: - Different headlines - Different CTA text or button colors - Image vs. no image - Short copy vs. longer copy

Track your CTR and conversion rate for each variation. Once a winner emerges, pause the underperformers and reinvest that budget. If you want a deeper look at this process, our post on A/B testing your ad campaigns walks through the full methodology.

7. Align Your Creative With Your Landing Page

One of the most common conversion killers is a disconnect between the ad and the landing page. If your ad promises a 50% discount and the landing page shows full prices, users will bounce immediately — and you'll pay for clicks that go nowhere.

Make sure the headline, offer, visual style, and messaging of your ad carry over consistently to your landing page. The user should feel like they've arrived exactly where they expected. This alignment builds trust and dramatically improves conversion rates.

Conclusion

Great ad creative isn't about fancy design — it's about clarity, relevance, and a compelling reason to act. When you match your creative to your format, lead with a strong value proposition, use a clear CTA, keep the design focused, and continuously test, you give every impression the best possible chance to turn into a click and every click a chance to become a conversion.
