Tips for designing a high-performing banner ad.

web banner sizes

You can choose to design your web banner yourself, hire a professional designer, or use an online generator.

Whichever way you choose, don’t forget the following:

  • Use visual hierarchy and balance

Banner ad design count on the visual balance of elements. Therefore, before finalizing a website banner size, consider these four basic elements.

  1. your brand logo: your logo shouldn’t cover too much space, but it should take enough space to create awareness for your brand.
  2. the value proposition- this should take up the most visual space because it’s what attracts users to the banner. It’ll include things like “Save $60”, “45% off,” and “Free Trial.”
  3. Element of urgency: This would include a countdown timer or words like “NOW”, and “Ends in 6 days” and would be close to the CTA.
  4. call-to-action: your CTA button invites users to click and should be placed strategically where viewers can easily notice. 
  • Use the right web banner size

As we’ve said earlier, you cannot rule out the importance of the right web banner size for your ad.

According to Google Adsense, high-performing banner sizes in terms of click rates are — 728 × 90px  for Leaderboard, 300 × 600px for Half Page, 300 × 250px for Medium Rectangle, 336 × 280px for Large Rectangle and 320 × 100px for Large Mobile Banner.

  • Keep the visuals and text simple but attractive

Regardless of the banner size, avoid stuffing your banner with too much content- images, slides, colors, and other elements. Simplicity is king.

Viewers only have a few seconds to look at your web banner. So, it’s important you stick to the most relevant content only. Keep the design simple and devoid of fancy elements. Use easy-to-read fonts and simple backgrounds.

  • Use appropriate CTA buttons at appropriate places

Call-to-action buttons increase the CTR (click-through rate) of your ad. Design them using contrasting colors and strategically position them below or on the left side of your copy.

 Make sure to keep them consistent throughout the ads.

  • Make sure the copy is clear

Clarity is non-negotiable in creating ads. You want your copy optimized with headlines and readable that wouldn’t run more than 4 lines. Consider using different sizes for your headline and body texts.

  • Use animations

Unlike static web banners, animated banner ads are more eye-catching and engaging. But before using them, consider what goal you want to achieve. Then, keep the animations simple with your message properly placed. 

  • Use the right file size 

Google AdWords recommended a maximum of 150 Kb for web banners. This is to ensure that ads load quickly. You want your banner to be below this size so that it can load fast before viewers scroll past it. Also, avoid flash banners because of their very slow load time. 

  • Choose the right section for your ad placement

Just like we noted earlier, the top of websites or in-between content is the best place to showcase your banners and get more engagement.

Conclusion

Display advertising- web banners- is important for businesses today, brick-and-mortar or online businesses. And choosing the right banner ad size is crucial to the success of your banner ad.

Understanding your industry and the ad sizes is crucial if you want to make the most of your campaign.
