If you’re not using Microsoft’s range of available ad extensions in 2024, you’re missing out! Ad extensions have several significant advantages: they can increase your CTR (click-through rate), will often reduce your CPC (cost-per-click) and, by providing additional information, often pre-qualify your audience before you pay for their click to your website!

All of these benefits combined provide an undeniable uplift to your PPC efforts, so are a must-have for accounts of all shapes, sizes, and budgets. And, ad extensions have their own reporting, so you can track the efficacy and impact of each of them individually.

1. Why use Microsoft advertising?

According to Statista’s data between January 2023 and 2024, across the US, Bing has a search engine share of 7.85% compared to Google’s majority of 87.48%. However, on tablet devices, this increases to a 13.59% market share across the nation, making up a significant proportion of the population.

While Bing doesn’t have the biggest network available or the largest amount of users when compared to Google, the smaller market share means that there is still benefit in exploring Microsoft advertising via Bing. With a smaller overall audience, advertisers and brands often ignore this form of PPC advertising; but multiple tests and studies have shown that, due to the reduced levels of competition, Microsoft advertising can be just as effective with a much lower CPC (cost-per-click) than Google. And, this performance can be enhanced further by using ad extensions.


2. Where do ad extensions appear?

When using Microsoft Ads, your ads and extensions will appear on Bing, Microsoft’s search engine. Underneath the paid ads at the top of the SERP (search engine results page), ad extensions will provide additional information. While there is a broad range of ad extension options available, extensions may include details such as store location, USPs, customer reviews and/or images. Multiple forms of ad extension may appear at any one time, such as in the example below, which features callout extensions, promotion extensions and sitelink extensions.

3. What types of ad extensions are there?

Microsoft advertising offers a wide range of ad extensions that are suitable for most, if not all, businesses. Crucially, the algorithm decides which ad extensions should appear at auction time for each user. Therefore, it’s important to implement as many ad extensions as are applicable to your business, product or service to increase the chances of them appearing.

With that said, let’s take a tour of the ad extensions available via Microsoft advertising.

Action extensions

Unique to Microsoft advertising, action extensions are CTA (call-to-action) buttons. These are a great choice for advertisers, as this means you can utilize more characters within your ad copy without having to add ‘call now,’ ‘book now,’ or ‘learn more today’ within each ad iteration.

Action extensions are designed to guide your prospective customers to the next step in their journey from the SERP from a predefined list of CTAs which includes ‘download,’ ‘apply now,’ ‘subscribe,’ ‘watch now,’ ‘compare,’  and plenty more. These CTAs also contain a link, which enables users to navigate directly to the most relevant page for them.

To create an action extension, you’ll need the following elements:

  • To choose action text from the ~40 predefined options available
  • A final URL for the action

Flyer extensions

Flyer extensions are a unique form of ad extension on Microsoft advertising that allow advertisers to share a ‘flyer’ to highlight a current deal, event or promotion. Each  flyer can be active for a maximum of one month.

Flyer extensions can be added at the account, campaign or ad group level, and up to five can be used and rotated through at any one time. The flyer must be created as an image with a relevant landing page for it to work effectively, and is likely to appear more often for broader search terms such as weekly deal or weekly sales.

To add a flyer extension, you’ll need:

  • Flyer image (Minimum size 220px by 220px. Image size cannot exceed 3.9 MB. No watermarks or free shipping text)
  • Final URL
  • A start date and an end date
  • (Optional) a description

Review extensions

Whether your business, product or your service has great ratings, it’s important to use them! In fact, 17%  of U.S. online consumers will read reviews and look for ‘social proof’ before making a purchase online, with 38% saying that reviews are ‘very important’ in helping them decide what to buy and where from. 

Reviews build trust and authority, and may even shorten the customer journey when they’re available upfront. However, review extensions are different from seller or merchant reviews, which are automated from your shopping feed.

Each of your campaigns can have up to 20 review extensions applied. When clicked from the SERP, review extensions will take the user to the third-party source of the review.

Review extensions require:

  • Review text in 67 characters or less (and to select whether this is an ‘exact quote’ or whether it’s ‘paraphrased’)
  • The source name for the review (i.e. Trustpilot, Yelp, TripAdvisor)
  • The source URL

Location extensions

While not as suitable for online-only brands, location extensions are great for anyone who has products and services available in a physical store. Location extensions can even be used if you provide products or services through affiliate stores, rather than your own.

These extensions will appear underneath your ad, not only showing the location of your nearest store, but giving an option for users to gain directions  based on their current location. You can apply location extensions in bulk via the Microsoft Advertising API if you have multiple locations, and the one closest to each individual user will appear (as long as it’s within 50 miles of the user).

To create a location extension on your Microsoft ads account, you’ll need:

  • Business name
  • (Optional) business phone number
  • Business address including state and zip code

Call extensions

Call extensions are a top pick for brands with inbound sales or inbound leads  made via phone call. They’re relatively straightforward to create; simply add the phone number to your ads via call extension, and this will appear beneath your ads when relevant.

For example, if a consumer searches for ‘[your brand] phone number,’ or if Microsoft knows from their history that they are more likely to call a business than to email, your call extension will appear.

To make inbound lead tracking as simple as possible, it’s best to use a phone number that’s used exclusively for inbound sales purposes. Otherwise, you’ll be tracking all forms of call - from inbound leads to customer service queries and complaints -  muddying the data and making it trickier to optimize your campaigns towards the types of phone calls you want!

microsoft-ads-call-extenions-exampleImage credit: Microsoft Ad Extensions - Call Extensions Example

To create a call extension, you’ll need to:

  • Add the country that the number is based in
  • Add the phone number with local code
  • Select whether to display your own number or a Microsoft advertising forwarding number to better track which phone calls were made from which search queries and/or ads
  • Decide on mobile whether you want to show your website and a phone number, or just the phone number when the call extension appears

Callout extensions

Callout extensions are a critical ad extension for all businesses advertising via Microsoft - as they enable you to share the highlights, features, and  USPs of your business, products and services. 

microsoft-ads-callout-extenions-exampleImage credit: Microsoft Ad Extensions - Callout Extensions Example

You can apply callout extensions at the campaign level and/or ad group level. Campaign level callout extensions should be used to reflect the highlights of your business such as ‘Free Returns,’ ‘20 Years of Expertise,’ ‘24/7 Live Chat’ and ‘5 Star Customer Service.

At the ad group level, you could showcase the benefits of that particular product or service, such as ‘Free Anti-Glare Upgrade,’ ‘World-Leading Waterproofing,’ ‘10 Year Guarantee,’ or ‘12 Month Warranty’. Each value has a limit of 25 characters and you can create a maximum of four callouts to appear at any one time.

Filter link extensions

Filter link extensions can be used to showcase key products or services. For example, a florist may use a header of ‘Flowers’ and the text of ‘Roses,’ ‘Lilies,’ ‘Peonys,’ etc. 

Similarly to both callout and sitelink extensions, filter link extensions on Microsoft advertising can be used to send users directly to the content that they’re looking for.

While the headers are predefined by Microsoft, filter link extensions allow you to create clickable links to each product or service type from the SERP. Filter link extensions are similar to sitelinks by providing links to relevant content for the user, but they take up a little less space on the SERP, and don’t require descriptions to be added. You’ll need a minimum of three categories per header, and a maximum of 10.

microsoft-ads-filter-link-extenions-exampleImage credit: Microsoft Ad Extensions - Filter Link Extensions Example

To create a filter link extension, you’ll need:

  • To select from the choice of preset headers
  • Values  for each item or group of items
  • A final URL for each item or group of items

Structured snippets

Structured snippets are a must-have ad extension for all businesses. With predefined headers, structured snippets utilize multiple 25-character headlines to add more information to your ads.

Apply structured snippets at the ad group level for the most relevant match between your ad copy and extensions. For example:

Brands: Nike, Adidas, EA Sports, New Balance
Service catalog: Wheel Alignment, Oil Changes, Winter Car Check, Tire Pressure
Areas: Manhattan, Brooklyn, Queens, Times Square

structured-snippet-extension-exampleImage credit: Microsoft Ad Extensions - Structured Snippet Extensions Example

The predefined headers are very similar to those available on Google’s structured snippets, and include:

  • Amenities
  • Brands
  • Courses
  • Degree programs
  • Destinations
  • Featured hotels
  • Insurance cover
  • Items (not available on Google)
  • Models
  • Neighborhoods (not available on Google)
  • Services (not available on Google)
  • Service catalog
  • Shows
  • Styles
  • Types

Extra tip: As with Google, you can apply up to 10 structured snippet values, but only four will appear on the SERP at once, and Microsoft will decide which four based on those that they believe will be the most relevant to the user and the search query. As well as this, you can, of course, apply multiple structured snippet headers to your ad groups, accounts or campaigns; however, only one - the most relevant - will appear at any one time.

Price extensions

Price extensions on Microsoft Ads are a top-choice for eCommerce or service–led businesses. A specific price or price point (such as ‘From’) can be assigned to each item. Price extensions will appear - where relevant - only when your ad appears at the very top of the SERP. 

This form of ad extension allows you to pre-qualify your audience, as they’re likely to only click the ad if the price extension shows a figure within their budget. This also allows you to be more competitive by displaying your prices from the get-go, allowing customers to click through and head directly to your item from the SERP.

Adding price extensions to your campaigns is likely to result in increased conversion rates from your online advertising efforts, particularly when your items are competitively priced.

Price extensions are made up of:

  • Language, currency, and type 
  • Price qualifier (such as from, up to and average)
  • Item headline
  • Item description
  • Price (including optional units:  per hour, per day, per week, per month, per year or per night)
  • Final URL and choice of mobile URL

Promotion extensions

Promotion extensions on Microsoft Ads are great, in particular, for eCommerce businesses, and any business with regular sales or promotion periods. This form of ad extension provides extra information from the SERP about current sales or discounts available, which often increases your CTR. 

Across Microsoft Ads, you can either select from their preset event periods - which will automatically stop serving at the end of the period - or you can select a broader occasion such as ‘Back to School’ and define your own date ranges. The latest list of occasions to select from for promotion is below:

  • Promotion type (monetary discount, percent discount, ‘up to’ monetary discount or ‘up to’ percent discount)
  • Final URL
  • Promotion details (such as on orders over or a promo code)

Sitelink extensions

Sitelink extensions on Microsoft ads are useful for brands with a large-scale website and a wide range of products and services. Underneath your ad, several links to various content from your website will appear. 

This form of ad extension allows you to tailor the customer journey to the content most relevant to them from the SERP - saving the user from navigating through your website from your landing page.  For example, customer reviews, contact information, special offers, rewards, products or to a customer sign-in portal may be used to tailor the customer journey.

On Microsoft ads, sitelinks extensions need:

  • 25-character headline text
  • Two 25-character description lines (unlike Google, these must be used for the sitelink extensions to appear)
  • Final URL

You can add a maximum of 20 sitelink extensions per campaign or ad group, and between two and eight will appear at any one time. You can also use sitelink extensions to direct to third-party websites such as affiliate stores.

App extensions

While not necessarily relevant for all businesses,  app extensions are the perfect way to increase app installs, app engagement and/or app interactions. They can appear on both branded and non-branded search terms, and can be selected to only appear when searches are made on an app-friendly device such as a mobile or tablet, on which users can download apps directly.

microsoft-ads-app-extenions-exampleImage credit: Microsoft Ad Extensions - App Extensions Example

To create an app extension on Microsoft ads,  you’ll need to:

  • Select the Operating System of the app
  • Share the package name (i.e.
  • Create link text (or CTA such as ‘Download Now’
  • Select whether you want the extension to only appear on mobile devices
  • To add a measurement or tracking URL

Unlike with Google, you’ll need to create separate app extensions for each OS if your app is available across both Android and iOS.

4. How do I create an ad extension?

  • Log into your Microsoft Ads account
  • On the left-hand menu, click ‘All Campaigns’ then ‘Ads & extensions’ followed by ‘Extensions’
  • From the dropdown list, select the type of extension you want to add
  • Select ‘Create ad extension,’ then ‘Add new [extension type]’
  • A pop-up will appear on the right-hand side where you can fill in the details for your ad extension(s)
  • Click ‘Save’ to save the ad extension to your account
  • Once you’ve added all the relevant ad extensions to your account, click ‘Save’ on the main page to save all changes

Final thoughts on Microsoft Ad Extensions

Microsoft’s substantial range and variety of ad extensions mean that all advertisers of all shapes and sizes will be able to utilize at least two or three forms of extension on their ads. The benefits are undeniable: increased CTR and conversion rates, no additional costs, enhanced ‘real estate’ on the SERP and improved ad ranks - making your ads work harder against the competition across Bing.

So, be sure to follow this guide to find, create and apply the right ad extensions for your brand, and enjoy reaping the benefits!
