A quick word about display advertising

So what are display ads? Digital display ads appear in a lot of formats — static ads and dynamic ones. Those are banners, video ads, search ads, Google ads, and images placed on websites, apps, or social media platforms to promote a product, service, or brand.

What is it good for?

Display advertising allows businesses to reach a large audience, generate brand awareness, and target specific demographics or interests through advanced targeting options.
Also, display ads are good for raising conversion rates. However, their primary task is to generate brand recall and increase brand recognition.

These campaigns can be orchestrated on a cost-per-click (CPC) or cost-per-impression (CPM) basis, often navigated through digital advertising platforms or the Google Display Network. Notably, integrating the best display ads network into your digital strategy can significantly enhance visibility and engagement, whether used individually or alongside other networks for maximum reach.

Programmatic digital display ad spending will hit the bar of $168.02 billion only in the US market alone, which signifies that brands are looking for the opportunity to automatically adjust bidding strategy, serve display advertising campaign messages across the channels, and target people on different platforms and specific websites.

8 Best practices for display advertising

1. Dive into AI and Machine Learning

Imagine this - you're optimizing your display ads using the power of AI and machine learning. These intelligent technologies can analyze large amounts of data, identifying trends and valuable insights to ensure that your ads effectively reach the right audience. Moreover, they are constantly testing ad elements to deliver your best possible version. Just think about the significant advantage you would gain!

2. Get Interactive and Go Immersive

Expand your marketing horizons. Instead of the usual, captivate your audience with ads that draw them in. Envision offering them a 360-degree video experience, an AR journey, or engaging them with an interactive poll for their opinions. It's not just about catching their eye; it's about creating unforgettable moments that leave a lasting impression, reinforcing brand affinity and retention.

3. Put Privacy at the Forefront

In the world of advertising, showing respect is crucial. Embracing a privacy-first approach involves being open about how you gather data, protecting it, and returning control to your audience. It's not just about being polite; it's about building trust and staying ahead as privacy standards change.

4. Unleash Creativity and Tell a Tale

Remember this text: "In a crowded sea of ads, storytelling can help your ad stand out. By incorporating creative storytelling into your display ads, whether through a series of narrative ads or visually compelling messages, you can make a real impact. Making an emotional connection can make a big difference in driving engagement and conversions."

5. Master the Art of Ad Sequencing

Just imagine taking your audience on a journey through a series of ads, like guiding them through a captivating story or a well-crafted sales funnel. Each ad serves as a chapter in a book, gradually revealing more information and skillfully leading them closer to making a purchase. It's all about constructing a consistent narrative that shapes your brand's identity in their minds over time.

6. Personalize with Dynamic Content

Why settle for the same old ad when you can tailor it to each viewer? Dynamic content customizes your ads based on the viewer's details - such as location, time of day, or their previous interactions with your site. It's like welcoming an old friend; you understand what interests them.

7. Optimize Like Mobile's Your Main Stage

In today's mobile-centric world, it's essential that your ads seamlessly integrate into the small screens that people are spending more and more time on. By optimizing for smaller screens, ensuring easy touch interactions, and leveraging intelligent features like geotargeting, you can position your ads right where your target audience is.

8. Embrace Sustainable Advertising

Make sure your ads line up with the principles of a more environmentally friendly world. Opt for energy-efficient servers, platforms that are conscious of their carbon footprint, and messages that reflect eco-friendliness. This is about sending a message that connects with environmentally conscious consumers, demonstrating that your brand stands for more than just making money.
Incorporating these insights into your display ads strategy isn't just following trends – it's setting them, ensuring your brand not only stands out but also signifies something deeper to your audience.

To sum up

You don't need to be a rocket scientist to create effective Google display ads or programmatic campaigns. Still, there are display ad best practices that can help you improve your performance. Be selective with your choice of images and text, and make sure they complement each other well for each display format. Also, ensure you've addressed any regulatory requirements before getting started.
