Microsoft Ads vs Google Ads: which is better?

In the comparison between Microsoft Ads and Google Ads, Google Ads delivers massive search volume and universal consumer reach, while Microsoft Ads offers 20 to 40 percent lower costs per click and an older, wealthier desktop audience with strong B2B intent. Most small and mid-sized businesses should launch on Google Ads first to capture core market demand, then import high-performing campaigns into Microsoft Advertising to capture incremental conversions at a lower cost.

Treating search advertising as an all-or-nothing choice between the two platforms is a mistake. Google remains the dominant search engine, but ignoring Microsoft Advertising means leaving out a significant portion of the desktop market that often converts at higher rates.

Market share and reach: Where the platforms differ

The most obvious difference between the two ad networks is search volume.

Google processes over 80 percent of all online searches in the US. It dominates mobile devices because it powers Android phones and is the default search engine on Apple Safari browsers. If your primary goal is maximizing total lead volume or selling consumer goods at scale, Google is essential.

Microsoft Advertising commands roughly 15 to 20 percent of US desktop search market share. Its network reaches beyond Bing to include Yahoo and DuckDuckGo. Bing is also the built-in default search engine on millions of Windows desktop computers used in corporate offices and professional workplaces.

Audience demographics: Who searches on Bing?

The audience using Microsoft search properties has distinct demographic characteristics that benefit specific types of businesses:

Higher household income and purchasing power

Data from Microsoft Advertising indicates that the Bing network audience skews slightly older, with a high concentration of users aged 35 to 64. A significant percentage of users have household incomes exceeding $100,000. These consumers frequently make buying decisions for home improvements, financial planning, and professional services.

The corporate desktop environment

Many enterprise employees work on company-issued laptops where IT administrators lock default browser settings to Microsoft Edge and Bing. These employees use Bing during business hours to search for software tools, legal services, supply chain vendors, and commercial contractors.

If you sell B2B services, reaching professionals at their work desks during the business day provides a distinct advantage. Read our guide on LinkedIn ads for B2B lead generation to see how paid search pairs with social B2B campaigns.

Key features available on Microsoft Advertising

Microsoft Advertising has introduced several features that make it attractive for paid search managers:

1. Direct LinkedIn profile targeting

Because Microsoft owns LinkedIn, Microsoft Advertising allows search campaigns to target or adjust bids for users based on their LinkedIn profile data. You can apply bid adjustments based on three professional filters:

• Company name: Increase bids for employees of specific target accounts.
• Industry: Prioritize users working in healthcare, finance, or construction.
• Job function: Target decision-makers in IT, human resources, or executive management.

This capability belongs only to Microsoft. Google Ads cannot match search queries directly to a user's verified professional job title.

2. Direct Google Ads campaign import

Microsoft built an automated import tool that connects directly to your Google Ads account. With a few clicks, you can import your campaigns, ad groups, responsive search ads, negative keyword lists, and tracking templates into Microsoft Ads.

You can set the tool to run on a weekly schedule. When you add new negative keywords or adjust ad copy in Google Ads, those changes copy over to Microsoft Advertising automatically, keeping your accounts aligned without duplicating your maintenance hours.

3. Greater control over search partner syndication

Both platforms distribute ads to third-party partner websites. However, Google bundles search partners into a single toggle, offering limited visibility into individual partner performance.

Microsoft provides publisher reports that display the exact third-party websites where your ads appeared. If a specific syndicate partner generates low-quality traffic, you can add that specific domain to an exclusion list without disabling the rest of the partner network.

Technical differences: UET Tag vs Google Tag

Conversion tracking operates similarly on both platforms, but you must install separate tags on your website:

Google Ads uses the Google Tag (gtag.js) to measure website transactions and phone call conversions.

Microsoft Advertising uses the Universal Event Tracking (UET) tag. The UET tag records page views, goal completions, and dynamic revenue values. Installing both tags through Google Tag Manager takes roughly 15 minutes. Once the UET tag is live, you can create conversion goals that mirror your Google Ads setup. This setup lets you measure cost per acquisition accurately across both platforms.

Bidding strategy differences to consider

Both platforms offer smart bidding powered by machine learning, but they perform differently depending on click volume:

Google's smart bidding algorithms (Target CPA and Target ROAS) thrive on large datasets. Because Google processes so many searches, its automated bidding models learn quickly and can adjust bids effectively in real time.

Microsoft Advertising offers automated bidding, including Maximize Conversions and Target CPA. However, because search volume on Microsoft is lower, the algorithm takes longer to gather the conversion volume required for aggressive automated bidding. For many small businesses running Microsoft Ads, starting with Enhanced CPC or manual bidding provides tighter cost control until the campaign accumulates steady monthly conversions.

How to divide your ad budget effectively

If you currently spend your entire paid search budget on Google, a sensible allocation strategy follows an 80/20 split:

Keep 80 percent of your search budget in Google Ads to capture the bulk of mobile and general search volume. Move 20 percent of your budget into Microsoft Ads by importing your top-performing Google campaigns.

Monitor the cost per acquisition across both channels over 60 days. In many industries, you will find that while Microsoft delivers fewer total leads, those leads arrive at a 15 to 30 percent lower cost per lead, improving your blended marketing return.
