TL;DR

What are the most common online advertising formats?

Core Definition: The most common online advertising formats are the various structures and types of digital advertisements that marketers can use to reach their target audience across websites, social media, search engines, and email. These formats, including display, video, search, and carousel ads, offer different ways to present a message and are selected based on campaign goals, budget, and the platform being used.

An effective online advertising campaign is a crucial component of any modern marketing strategy, complementing inbound efforts. While 'online advertising' is a broad term, it encompasses a wide variety of ad formats, each with unique strengths and applications. Understanding these common types is the first step to building a successful digital campaign.

  • Display and Banner Ads are foundational, cost-effective visual ads suitable for almost all platforms, ideal for raising brand awareness.
  • Video Ads are highly engaging and perfect for storytelling or product demonstrations, though they are typically the most expensive format to produce and run.
  • Carousel and Collection Ads are best for social media, allowing you to showcase multiple products or build a narrative with a series of images or videos in a single, interactive unit.
  • Search Engine and Email Ads target users with high intent, either by appearing in search results for specific keywords or by reaching a curated list of leads directly in their inbox.

An online advertising campaign is a series of advertisements that use the internet to reach consumers. This approach is the perfect complement to an Inbound Marketing strategy. Even though marketers use the umbrella term "online advertising," it's important to remember that many formats are available for online advertisers.

This article will provide an introduction to the most common ad formats available online:

  • Display ads
  • Video Ads
  • Banner Ads
  • Carousel Ads
  • Collection Ads
  • Email Ads
  • Search Engine Ads
  • Interactive Ads

This isn't a comprehensive list of ad formats since new formats emerge every other year or can be custom-built for the right price. But these are the most prevalent and can be bought based on a Cost-Per-Click (CPC) basis or by impressions.

Display Ads

Display ads are a form of online advertising that uses visual media, like images or graphics, to convey a marketing message on websites, apps, and social media platforms. Almost all platforms will allow you to run display ads. They're simple enough to use and set up and compelling enough that you can't ignore them. Image ads are a great starting point for any new marketer; you can't go wrong with them.

Display ads are the best choice if you don't need much text, and you can communicate all your information in one single image.

When it comes to display ads, generally, you'll have minimal space for text. Make sure you're using whatever text you have carefully, and don't forget to include the right keywords and powerful words to make the most out of your text. You can include some text in the image, but there isn't much room for textual information in display ads. Also, ensure the ad clicks through to the site or content you want to direct your customers to.

There are many ways to go about display ads. You don't need to have a professional photographer take a fantastic picture to make a good display ad. You may not even need to use a camera at all. Sometimes something as simple as a graphic and your logo and brand name can be enough to make an image ad effective. Overloading a small image ad with tons of information can also affect your ad's effectiveness. Remember that sometimes, less is more. Ensure you get all the information you want across with as little clutter as possible. If you struggle to communicate everything in just one image, you may choose another ad format, like video ads.

How to Build a Multi-Format Online Advertising Strategy

Learn how to select and implement the most effective online advertising formats for your marketing goals. This workflow covers everything from foundational display ads to highly engaging interactive and video formats.

Effort: 1-2 weeks Tools Needed: 3
1
Deploy display ads for foundational visibility.

Start with simple image-based display and banner ads to build brand awareness. Keep text minimal, use powerful keywords, and ensure a clear click-through path to your desired landing page.

2
Launch video ads to demonstrate product functionality.

Utilize video ads on social media and video platforms to show your product in motion. Combine strong visual and audio elements to deliver impactful messages that static images cannot convey.

4
Distribute email ads to nurture existing leads.

Send targeted, image and text-based ads directly to your mailing list to build long-term relationships. Invest in automation services to efficiently manage your lists without paying for external ad space.

5
Implement search engine ads for high-intent queries.

Set up PPC advertising on search engines like Google or Bing to capture users actively searching for relevant keywords. Ensure your ad aligns tightly with specific search queries to maximize SERP visibility.

6
Develop interactive ads to maximize audience engagement.

Design playable mini-games or poll ads to actively engage users before driving them to a landing page. Use these niche formats carefully, ensuring they enhance rather than disrupt the user experience.

Video Ads

Video ads are a type of online advertising that uses moving video content to promote a product or service, often appearing before, during, or after other video content on platforms like YouTube and social media. Given the rise in video content across all online platforms, it's no surprise that video ads have been growing alongside them. Whenever an individual looks to play a video on most online platforms, a video ad can be attached. Of course, that usually means you can only run video ads on platforms that feature video content, but not exclusively. Some display ads can offer expandable ad units that can also play video. Think of these as a traditional TV commercial break while watching a video or scrolling through a website.

Video ads are best used to show your audience something in motion or share content more impactfully and entertainingly. Maybe you want to show off the functionality of your product or people's reactions to it or give them a quick summary of a recent blog post you've published. If a simple image isn't enough to send the message, you should go for video ads.

Remember that videos don't need to be filmed footage (just like display ads don't need to be photographed); they can also be animated. Even though it's all video, there's a lot of variety in what you can put inside your ad unit. Ensure you're using both the visual AND the audio aspects of video ads. You won't find the option to have audio in many other ad formats, so if you have a message that needs to be heard, this is the format for you.

You want to ensure that your video ad hits all your marketing objectives precisely and effectively because video ads are the most expensive.

Like display ads, you want to ensure you're making the most of your text. The good thing about video ads is that you can work around the textual limitations by adding in a voiceover, dialogue or having text appear during your ad as it progresses. Remember that you also want to avoid overloading your video with information. Include a CTA that drives them to the relevant site on your webpage. Again, as a general rule, less is more in your ad space to maximize impact and interest.

Banner Ads

Banner ads are a type of display ad that appears in designated spaces on a webpage, typically at the top, bottom, or sides. Whatever space a platform has on its webpage or app is where banner ads can appear. Banner ads are most often at the top or sides of a page, but you can also see them appearing in the center or the bottom of the page. The placement depends on the content that the platform displays and how it structures its website.

Banner ads aren't the most standout format. They might seem too ubiquitous and could blend into the page's background, but you shouldn't ignore them. While it would be a mistake to build your entire advertising campaign around banner ads exclusively, they should be a part of a diverse ad format mix or part of a page takeover/re-skin. The upside is that banner ads are usually very cost-effective. The downside is that they're not outstandingly noticeable. You're getting what you're paying for.

There isn't much variety in banner ads. You're usually limited to text and visuals, but other non-traditional banner formats, such as a 'rollover to expand' banner ad, are becoming increasingly common. You could also embed a video into your banner ads, which the user triggers. If your ad is heavy on text, banner ads are usually a good choice since they allow a lot of space for text and CTAs.

Carousel Ads

Carousel ads are an interactive ad format, common on social media, that combines multiple images or videos into a single unit that users can scroll through. They require the user to scroll through the different parts of the carousel to receive the whole ad experience. Social media platforms format carousel ads to match native content on their site so they appear within a user's feed seamlessly instead of being relegated to their own "advertising space." Carousel ads usually benefit from social media interactions, such as likes, comments, and shares.

This ad format is highly versatile. You can have up to 10 pieces of media (videos, images, or a mix of both), meaning that the amount of information you can communicate to the viewer is unmatched by other formats.

Building a carousel ad takes time and attention. Remember that it's up to the user to scroll through the carousel. That means it's up to you to get the user to scroll through. This means that each slide of the carousel should serve a specific purpose. The user's attention should be captured by the early slides (and especially the first) to make them want to learn more. This can be a special offer, a cool new feature, or a strong catchphrase.

As they progress through the carousel, the ad's information should become more in-depth. There's no point in capturing someone's attention by the 8th slide. If the first few slides don't hook them, they won't get through your carousel. By the time they finish going through the ad unit's images, you should want the user to know more than just general knowledge about whatever you were advertising to them and demonstrate a straightforward journey of where they should go and what they should do to learn more.

Collection Ads

Collection ads are a social media ad format, similar to carousels, specifically designed to showcase a collection of products from a catalog, allowing users to browse and purchase directly. Like carousel ads, collection ads feature a selection of content the user can scroll through. They also appear primarily on social media (most notably Facebook). Where carousel ads are designed to relay different levels of information to a user, collection ads are more focused on displaying products.

Structuring collection ads isn't as simple as carousel ads. It's hard to know which products should come first and which depend on the user scrolling through them. Generally, it's safe to advertise your most popular products first and progressively move toward the more niche ones throughout the collection. Luckily, platforms like Facebook provide a modular algorithm for collection ads that allow for automated determination of the products' order in the ad. If you can't determine the order, just let an algorithm do it.

Email Ads

Email ads are a form of direct marketing where promotional content is sent directly to a user's email inbox as part of a larger email marketing campaign. These ads are a strong foundation for any advertising campaign, especially inbound. You send these ads directly to the email inboxes of people on your mailing list. Email ads are incredibly effective and unique in many ways.

First, they are ads that you run yourself. Email ads aren't dependent on being run on someone else's platform. You get a mailing list and send emails; that's it. The cost of email ads is mostly within the design and production of the ad itself rather than the costs of running them. Instead of paying for ad space, you can spend that money on automation services to make managing mailing lists easier.

Email ads aren't as limited as other formats. Usually, ads must be within a small space offered by a platform, but email ads don't need to abide by those rules. As long as it can be sent in an email, it can be done in an email ad. This is why email ads are most typically image and text-based. While you don't want your ad to be too long, you can be sure that you won't feel limited in space. You have more than enough room in an email to communicate everything you want to hit all your advertising goals.

One last unique aspect of email ads is their recurring nature. To get email ads, viewers need to be on a mailing list. If they're on a mailing list, you've converted them into a lead and have a chance to change them into a prospect. This means you can create an advertising experience and a relationship beyond one ad.

Search Engine Ads

Search engine ads are a form of pay-per-click (PPC) advertising where text-based ads are displayed at the top of a search engine results page (SERP) based on a user's specific search query. These search engine ads are typically PPC advertising displayed by search engines. These are mostly Google ads, but that's not all search engine ads encompass. Any platform that has its own search engine has the possibility of offering search engine ads. Whether it's Google, Bing, or other platforms like Indeed or Kijiji, you can display ads through their search engines.

Search engine ads will appear at the top of the SERP, presented as "promoted" results to the users. The effectiveness of search engine ads will largely depend on the keywords associated with your ad. If your ad is relevant to very general, widely searched terms, you should look into and use search engine ads. If your product is more niche, it may be harder to have your ad appear in many searches.

Interactive Ads

Interactive ads are a unique ad format that requires user participation, such as through a poll, mini-game, or playable demo, to engage the audience actively. These ads are not just shown and passively consumed by the audience. This can be a playable ad or, most often, a poll ad, where users give their input while being advertised and then driven to a landing page. Interactive ads are unique to online platforms. Traditional advertising media don't offer simple ways for an audience to interact with an ad.

These kinds of ads offer huge upsides paired with considerable downsides as well. Unlike versatile and adaptable image ads, interactive ads are much more niche and should be used following their niche.

The good thing about interactive ads is that they engage the audience on an unmatched level compared to any other ad format. Getting your audience to play a little mini-game before displaying your ad to them creates a much more enjoyable and positive experience than a typical ad does.

The problem with interactive ads, however, is they are much more challenging to make, as they often involve some coding paired with audio-visual design, and platforms rarely implement them. They can also be quite intrusive to a user's experience and can annoy them if designed poorly or if the user doesn't have the right plug-ins or capacity to get the full experience.
