Google Ads vs Microsoft Ads

In short: Both are keyword-triggered search auctions with near-identical campaign structures, which is why Microsoft Ads, formerly Bing Ads, built an import tool that copies a Google Ads account almost directly. The split is volume and competition: Google covers far more search traffic, while Microsoft's network - Bing, Yahoo, DuckDuckGo, and syndicated partners - is smaller but often cheaper per click with an older, more desktop-heavy audience. Microsoft also offers LinkedIn profile-based targeting layered on top of search, which Google has no equivalent for. If you're capacity-constrained, put the first dollar in Google; once Google is tuned, Microsoft is close to free incremental volume for the campaign-building work you already did.

Google Ads

Runs paid ads across Google Search, YouTube, Gmail, Maps, and millions of partner sites, billed mostly per click through a live auction.

The largest search-driven ad system, spanning keyword-triggered Search results plus Display, Shopping, YouTube, and automated Performance Max inventory. It suits businesses whose customers already search for what they sell, because the intent is explicit. The usual mistake is leaving new campaigns opted into Search Partners and Display by default, then blaming Search for the cheap, low-quality traffic that actually arrived from elsewhere.

Microsoft Ads

Search advertising on Bing, Yahoo, DuckDuckGo, and partner sites, formerly called Bing Ads, with an import path from Google Ads campaigns.

The search network formerly known as Bing Ads, covering Bing, Yahoo, DuckDuckGo, and syndicated partners, plus LinkedIn profile targeting that search rivals do not offer. Volume is far smaller than Google's, though competition is often lighter and the audience skews older and more desktop-heavy. The typical error is importing Google campaigns once and never maintaining them, so budgets and negatives drift apart.

Side by side.

The differences that actually change what happens in your account.

	Google Ads	Microsoft Ads
Search volume available	The largest pool of search queries by a wide margin, across nearly every category.	A fraction of Google's volume, concentrated on Bing, Yahoo, DuckDuckGo, and syndicated partner sites.
Setup effort	Built from scratch or migrated in.	Usually imported directly from an existing Google Ads account, then adjusted rather than rebuilt.
Typical competition level	High in most commercial categories, since most advertisers default here first.	Often lighter, since many advertisers never get around to maintaining a Microsoft account after the import.
Audience skew	Broad, roughly mirrors general internet search behavior.	Skews older and more desktop-heavy than Google's average searcher.
Unique targeting option	No equivalent to profile-based B2B targeting inside the ad platform itself.	LinkedIn Profile Targeting - layers company, industry, and job function onto search campaigns, which Google Search cannot do natively.
Campaign structure parity	Native structure - keywords, ad groups, campaigns, extensions and assets.	Mirrors Google's structure closely enough that imported campaigns mostly just work, with naming and minor feature gaps to reconcile.
Failure mode	Search Partners and Display left opted in dilutes traffic quality.	Imported once and abandoned - negatives, budgets, and bids drift out of sync with the Google account they were copied from.

What actually separates them.

Microsoft Ads' import tool copies campaigns, ad groups, keywords, and ads directly from Google Ads, so the two platforms share campaign structure closely enough that building for one mostly builds for both.

Google's volume advantage means the same keyword typically returns far more impressions there than on Microsoft's combined network, so account managers usually size Microsoft budgets as incremental, not primary.

Microsoft layers LinkedIn Profile Targeting onto its search campaigns, letting you narrow by company, industry, or job function in a way Google Search has no native equivalent for.

Because fewer advertisers actively maintain their Microsoft accounts, cost per click in the same category is often lower there even with an identical keyword list and match types.

An import from Google is a one-time snapshot, not a sync, so keyword and negative changes made in Google afterward do not propagate to Microsoft unless you re-import or maintain both manually.

Which one should you use?

Use Google Ads when

You need maximum reach and your budget can absorb higher competition and cost per click.
Your business depends on mobile search volume, where Google's share is largest.
You're just starting out and need one platform mastered before adding a second.
Your category has heavy competition and you need Google's scale to hit volume targets.

Use Microsoft Ads when

You already have a tuned Google Ads account and want incremental volume with minimal new setup work.
Your buyers skew older or work primarily on desktop during business hours.
You sell B2B and want to combine search intent with company or job-title targeting.
Your category is competitive on Google but under-contested on Bing because few competitors bother to expand there.

Common questions.

Is Microsoft Ads still called Bing Ads?

The platform was renamed Microsoft Advertising some years ago, though 'Bing Ads' is still the term most people search for, and its search inventory still centers on Bing. The console and account structure changed name, not the underlying search engine.

Can I just copy my Google Ads account over?

Yes, Microsoft Ads has a built-in import tool that pulls in campaigns, ad groups, keywords, and ads from a connected Google Ads account. Treat it as a starting point, not a finished setup - bid strategies, extensions, and some targeting options don't map one-to-one and need review after import.

Is Microsoft Ads worth it for a small budget?

Usually yes as a second platform once your Google account is stable, because the import work is largely done for you and the incremental cost per click is often lower. It's rarely the right place to start from zero given the smaller volume.

Why is my imported Microsoft campaign underperforming compared to Google?

The most common cause is neglect - budgets, negative keywords, and bid adjustments made in Google after the import never carried over, so the Microsoft campaign is running on a stale copy of a strategy that's since moved on. Treat it as its own account needing its own maintenance, not a mirror that stays in sync automatically.

Or stop choosing between them.
