Most SMEs running paid search have never logged into Microsoft Advertising. They set up Google Ads, got results (or didn't), and assumed Bing ads were either irrelevant or too small to matter. That assumption is worth questioning, especially if your cost per click on Google has been climbing.
This article explains what Bing ads actually are, how they compare to Google Ads for SMEs, where the channel genuinely performs, and why most small businesses either ignore it entirely or manage it badly.
Bing Ads: What the Channel Actually Is
Bing ads is the informal name for Microsoft Advertising, the paid search network that serves ads across Bing, Yahoo, AOL, and a collection of partner sites collectively called the Microsoft Audience Network. When someone searches on Bing and clicks a sponsored result, that is a Bing ad.
The platform uses a pay-per-click model structurally similar to Google Ads. You bid on keywords, write ad copy, set budgets, and pay when someone clicks. The auction mechanics, Quality Score equivalent (called Ad Relevance), and campaign types mirror Google closely enough that most Google Ads accounts can be imported directly into Microsoft Advertising with a few clicks.
As of 2026, Microsoft's search network holds somewhere between 6 and 10 percent of the UK search market depending on the source and device type. That sounds modest. On desktop, the share is noticeably higher, particularly among older demographics and users on corporate-managed Windows machines where Bing is the default browser.
For context on how paid search works more broadly, what PPC ads actually are and how they work is worth reading before diving into channel specifics.
Why SMEs Underestimate Bing Advertising
The honest answer from nine years running a marketing agency: most SMEs ignore Bing ads not because they analysed the channel and rejected it, but because they never seriously considered it. Google Ads gets all the attention, the budget, and the management time. Bing gets nothing.
This creates a specific opportunity. Because fewer advertisers compete on Bing, auction pressure is lower. Average cost-per-click tends to run 20 to 40 percent below equivalent terms on Google, depending on the industry. In sectors like legal services, financial products, and B2B software, where Google CPCs can reach double figures, that differential is significant.
The trade-off is volume. Bing's search network will never deliver the raw traffic Google does. If you are in a niche that requires scale, or your margins depend on thousands of clicks per month, Bing alone will not carry the weight. But as a secondary channel running alongside Google, the economics often make sense.
Understanding how much Google Ads actually costs for SMEs gives you a useful baseline before deciding how to allocate budget across channels.
How Bing Ads Compare to Google Ads
The structural similarities between Bing ads and Google Ads make switching or duplicating campaigns relatively straightforward. Microsoft Advertising has an import tool that pulls campaigns directly from Google Ads, including keywords, ad copy, bid strategies, and audience lists. In practice, you spend 20 minutes on the import and another hour cleaning up anything that did not transfer cleanly.
The differences are operational rather than structural. Google's auction has more data, more automation options, and considerably more sophisticated machine learning behind its Smart Bidding. Microsoft's equivalent automated bidding works, but it needs more time and volume to learn effectively. On accounts with limited monthly clicks, Google's automation simply has more signal to work with.
| Feature | Google Ads | Bing Ads (Microsoft Advertising) |
|---|---|---|
| UK search market share | ~90% | ~6-10% |
| Average CPC (search) | Higher | 20-40% lower on average |
| Import from competitor | No direct tool | Yes, imports from Google |
| Automated bidding | Mature, data-rich | Functional, slower to learn |
| LinkedIn audience targeting | No | Yes (unique to Microsoft) |
| Minimum monthly spend | No minimum | No minimum |
| Desktop user share | Lower | Notably higher |
One feature Google does not have: Microsoft Advertising lets you layer LinkedIn profile data onto your search campaigns, targeting by job title, industry, or company size. For B2B advertisers, this is genuinely useful, not a gimmick.

Where Bing Ads Actually Perform Well
From managing accounts across multiple industries, the pattern is consistent. Bing ads tend to outperform expectations in specific contexts rather than universally.
B2B services benefit the most. The Microsoft Audience Network skews towards desktop, corporate environments, and professional demographics. If you are selling to business owners, finance directors, or procurement managers, the Bing audience profile is often closer to your buyer than Google's broader mix.
Retirement-age consumers are heavily over-represented on Bing relative to their share of the general population. Categories like healthcare, financial planning, legal services, and home improvement consistently see strong conversion rates on Bing because the audience is more considered, less impulsive, and more likely to be searching from a desktop at home.
Geography matters less than demographic. Bing's UK presence is not concentrated in any particular region — it is spread across the country but weighted towards certain user types. If your Google Ads campaign targeting is already refined, Bing is a reasonable next step rather than a starting point.
Managing Bing Ads Without Wasting Time
The honest operational problem with Bing ads for most SMEs is management overhead. Running two paid search accounts doubles the number of things that need watching: bids, budgets, search terms, ad copy tests, conversion tracking. Most small businesses do not have the internal resource to manage one account well, let alone two.
This is where the arithmetic breaks down. Bing might offer lower CPCs, but if no one is actively adjusting bids, pausing underperforming keywords, or catching budget leakage, the efficiency gains evaporate. An unmanaged Bing account running on imported Google settings often drifts into spending on irrelevant queries because the search term reports are not being reviewed.
Overtime is an AI agent built to handle exactly this kind of active management. It logs into Google Ads accounts, adjusts bids, pauses underperformers, reallocates budget, and sends plain-English summaries of what changed and why — removing the manual work that most SMEs cannot realistically sustain.
For SMEs considering whether an AI agent or a traditional agency makes more sense for this kind of management, the comparison between PPC agency services and AI agents lays out the practical differences.
Should SMEs Bother with Bing Ads in 2026
The question is not whether Bing ads are as powerful as Google Ads — they are not. The question is whether the return on the additional budget and management time is positive. In most cases, for SMEs already running Google Ads competently, the answer is yes, with conditions.
The condition is management. A well-managed Bing account running at lower CPCs can generate meaningful incremental revenue. A neglected Bing account running on stale imported settings generates low-quality traffic and wasted spend. The channel itself is not the variable. The management is.
SMEs who want to explore Bing ads without adding management complexity should think about what ongoing optimisation actually looks like before committing budget. The paid search management service guide covers what active management involves at a practical level, which makes the build-or-buy decision easier.
If you are already working through Google Pay Per Click management and finding it demanding on internal time, adding Bing without additional support will compound the problem rather than solve it.
For SMEs evaluating whether to use an AI PPC agent or a specialist Bing advertising agency, the volume question is the deciding factor. Low Bing volume often means an agency retainer is disproportionate to the revenue at stake. An AI agent managing both channels simultaneously is frequently the more proportionate answer.
If you are ready to test Bing ads alongside your existing Google Ads activity, the practical next step is to audit your current Google account first. Understand where your budget is going, which campaigns are actually converting, and what your baseline CPC looks like. Then import into Microsoft Advertising and let it run with active oversight from day one. Overtime's pricing is structured for SMEs managing exactly this kind of dual-channel setup without a full in-house team.
You can also review how Overtime manages Google Ads specifically to understand what active management looks like before deciding whether to extend it to Bing ads as well. The full details of how it works are available if you want to see the specifics before committing.

FAQ
What are Bing ads and how do they work?
Bing ads is the informal name for Microsoft Advertising, a pay-per-click network that serves sponsored results across Bing, Yahoo, and partner sites. Advertisers bid on keywords, write ad copy, and pay when a user clicks. The model is structurally similar to Google Ads and campaigns can be imported directly from Google into Microsoft Advertising.
How do Bing ads compare to Google Ads for SMEs?
Google Ads offers significantly higher search volume, more mature automation, and broader reach. Bing ads typically offer lower cost-per-click, less auction competition, and a desktop-heavy audience that skews professional and older. For most SMEs, Bing works best as a secondary channel running alongside Google rather than a replacement for it.
Why are my Bing ads not converting?
The most common cause is poor ongoing management. Campaigns imported from Google Ads and left without optimisation accumulate irrelevant search terms, stale bids, and budget waste. Bing's automated bidding also needs sufficient conversion volume to learn effectively, which can be a problem on lower-traffic accounts.
Should SMEs use a Bing advertising agency?
It depends on Bing volume. If your monthly Bing spend is modest, a specialist agency retainer may cost more than the channel generates. An AI agent managing both Google and Bing simultaneously is often more proportionate for SMEs, as it provides active management without the overhead of a separate agency relationship.
Can Bing ads target by job title or industry?
Yes. Microsoft Advertising offers LinkedIn profile targeting, which lets you layer job title, industry, and company size data onto search campaigns. Google Ads does not offer this. It makes Bing ads particularly relevant for B2B advertisers who want to reach specific professional audiences through paid search.
