Most businesses searching for a bing advertising agency are doing so because Google Ads has become expensive, competitive, or simply unmanageable — and Microsoft Advertising looks like a quieter, cheaper alternative worth exploring. That instinct is not wrong. But the decision deserves more scrutiny than most agencies will give it.
This article breaks down what a bing advertising agency actually does, how Microsoft Advertising compares to Google Ads for SMEs, where the real value lies, and why AI-managed Google Ads may serve most small businesses better than splitting budget across two networks.
What a Bing Advertising Agency Does
A bing advertising agency manages paid search campaigns on Microsoft Advertising, the platform that serves ads across Bing, Yahoo, and the Microsoft Audience Network. The work involved is structurally similar to Google Ads management: keyword research, ad copywriting, bid management, audience targeting, and ongoing optimisation based on performance data.
Where agencies differentiate themselves is in how actively they manage accounts. Some run quarterly reviews and call it done. Others — the better ones — are inside accounts weekly, adjusting bids by device, time of day, and audience segment. After running a marketing agency for nine years, we saw firsthand how infrequent account access was the single biggest cause of wasted spend. Campaigns left untouched for three weeks in a competitive market can drift badly.
Microsoft Advertising allows direct import from Google Ads, which most agencies use to set up Bing campaigns quickly. That is convenient, but it also means the same structural weaknesses in your Google campaigns get replicated on Bing. A good bing advertising agency audits before importing, not after.
The agency model also comes with management fees, typically 10–20% of ad spend or a flat monthly retainer. For SMEs spending under £3,000 per month on ads, those fees can consume a disproportionate share of the budget before a single click is bought.
Google Ads vs Bing Advertising: Honest Comparison
The case for Microsoft Advertising is real. Bing commands roughly 6–8% of UK search volume, but its audience skews older, more affluent, and more likely to be in a workplace using a Microsoft device. For certain sectors — B2B services, financial products, legal, home improvement — that demographic profile converts well.
Cost-per-click on Bing is generally lower than Google, sometimes significantly so. Less competition for the same keywords means cheaper clicks, and cheaper clicks mean more room to test without burning through budget. That is a genuine advantage, not marketing spin.
But volume matters. Lower CPCs mean little if there are not enough searches to drive meaningful results. For many SMEs in niche markets or local geographies, Bing simply does not generate enough traffic to justify a separate management overhead — whether that is agency fees or internal time.
Here is a straightforward comparison of what SMEs typically encounter across both networks:
| Factor | Google Ads | Microsoft Advertising (Bing) |
|---|---|---|
| UK search volume share | ~90% | ~6–8% |
| Average CPC (UK, broad sectors) | Higher | 20–40% lower on average |
| Audience demographic | Broad | Older, higher income, B2B leaning |
| Competition level | High | Lower |
| Import from Google | N/A | Yes, direct import available |
| SME management complexity | High | Moderate |
| Typical agency fee | 10–20% of spend | 10–20% of spend |
The honest view: for most SMEs, Google Ads delivers volume that Bing cannot match. The question is whether you are managing Google well enough before adding a second network.

Should SMEs Use a Bing Advertising Agency in 2026
The answer depends on what you are already doing. If your Google Ads account is consistently profitable, well-structured, and actively managed, adding Bing is a reasonable next step to capture incremental volume at lower cost. In that scenario, a bing advertising agency can add genuine value — especially if they have sector-specific experience.
If your Google Ads account is not yet profitable, or if it is running on autopilot with infrequent optimisation, adding Bing is the wrong move. You would be compounding the problem by splitting attention and budget across two under-managed channels.
The agencies pitching Bing management rarely lead with that caveat. They have financial incentive to take on the account regardless. That is not a criticism — it is just the structural reality of how agency relationships work.
For SMEs with monthly ad budgets under £5,000, the priority should almost always be getting Google right first. That means active bid management, pausing underperforming keywords, reallocating budget toward what converts, and reviewing account health at least weekly. Most businesses are not doing this.

How Bing Advertising Agencies Price Their Services
Pricing structures across bing advertising agencies follow a few common models. Understanding them helps you assess whether the fee is proportionate to the work being done.
The percentage-of-spend model charges 10–20% of your monthly ad budget as the management fee. At £2,000 per month in ad spend, that is £200–£400 in fees on top. The incentive misalignment here is well documented: the agency earns more when you spend more, which does not always align with spending efficiently.
Flat monthly retainers are more predictable. Expect £400–£800 per month for a competent bing advertising agency handling a single account, though pricing varies significantly by agency size and location. London-based agencies typically charge more than regional ones, though the quality of work does not always reflect the difference.
Performance-based models — where fees are tied to leads or revenue — sound attractive but are rare in practice, partly because attribution is messy and partly because agencies carry risk they cannot fully control.
For context on how ad management fees compare more broadly, PPC Agency Services: What SMEs Actually Get covers the full picture.
One thing agencies rarely disclose upfront: the bulk of account management time is often handled by junior staff, not the senior person who pitched you. After nine years running an agency, we saw this pattern constantly. The person managing your account week-to-week may have six months of experience. That is not necessarily a dealbreaker, but it is something to ask about directly.
What Active Campaign Management Actually Requires
Whether you are on Google, Bing, or both, the mechanics of good paid search management are the same. Bids need adjusting based on device performance, time of day, and audience segment. Underperforming keywords need to be paused, not ignored. Budget needs to move toward what is working, not stay static across all campaigns.
These are not occasional tasks. In a competitive market, a campaign left unchanged for two weeks can drift meaningfully — quality scores drop, impression share shifts, competitors adjust their bids and you do not respond. The best results come from accounts that are touched frequently, not reviewed quarterly.
This is where the agency model has a structural ceiling for SMEs. Agencies manage dozens of accounts simultaneously. The economics of a £400-per-month retainer do not support daily account access. You are paying for access to expertise, but the time that expertise is applied to your account is limited.
Overtime is an AI agent built specifically to solve this problem for Google Ads. It logs into your account directly, adjusts bids, pauses underperformers, reallocates budget based on live performance, and sends you a plain-English summary of what it did and why. It does not replace strategic thinking, but it does the active management work that most SMEs either cannot afford an agency to do daily or do not have time to do themselves.
For SMEs who want to understand the trade-off between AI management and traditional agency relationships, Best PPC Agency or AI Agent: What SMEs Need covers that decision in detail.
When a Bing Advertising Agency Is Worth Hiring
There are genuine use cases where a bing advertising agency earns its fee. B2B companies targeting professionals during working hours, on workplace devices, are the clearest example. The Microsoft Audience Network reaches LinkedIn audiences through display ads — a feature with no direct Google equivalent that can be valuable for the right product.
Sectors with high average order values and long sales cycles — legal services, financial planning, consultancy, commercial property — often find Bing's lower competition means they can maintain visibility for less. If a single converted lead is worth thousands of pounds, paying more for management makes mathematical sense.
Retailers and e-commerce businesses, by contrast, usually find Bing volume insufficient to justify the overhead. The volume difference between Google and Bing is too stark for businesses that need scale.
If you are already running Google Ads profitably and want to understand what broader paid search management involves, What a Paid Search Service Actually Does is a useful reference.
The right bing advertising agency will tell you honestly whether Bing makes sense for your business before taking your money. If the agency skips that conversation, that tells you something important about how they operate.
For SMEs not yet at that stage — still trying to get Google Ads to perform consistently — AI Powered PPC Management for Small Businesses explains what consistent, frequent management actually looks like at a cost that makes sense for smaller budgets.
If you are evaluating a bing advertising agency and want to see what actively managed Google Ads looks like before committing to a multi-channel strategy, Overtime's pricing is a useful benchmark — the AI agent manages your Google account daily for a fraction of what a traditional agency charges.
The most productive next step today is to audit your current Google Ads account before expanding to Bing. Look at which campaigns have not been touched in the last 30 days, which keywords are spending without converting, and where budget is sitting in underperforming ad groups. Fix those first. A bing advertising agency adds value at the margin — but only when the core is already working. If you want that active management handled automatically while you focus elsewhere, Overtime's Google Ads management is worth reviewing.

FAQ
What does a bing advertising agency actually manage?
A bing advertising agency manages paid search campaigns on Microsoft Advertising, which includes Bing, Yahoo, and the Microsoft Audience Network. This covers keyword targeting, ad copy, bid management, and performance optimisation. Some agencies also manage the import and adaptation of existing Google Ads campaigns into Microsoft Advertising.
How much does a bing advertising agency typically charge?
Most bing advertising agencies charge either a percentage of ad spend (typically 10–20%) or a flat monthly retainer (usually £400–£800 for a single account). The right structure depends on your budget size — percentage models favour smaller budgets, while flat fees can be more cost-effective as spend scales.
Should I use Microsoft Advertising if my Google Ads are not working?
No. If your Google Ads are underperforming, adding Bing will compound the problem rather than solve it. Fix the structural issues on Google first — bid management, keyword relevance, budget allocation — before expanding to a second network with lower volume.
Why is Bing advertising cheaper than Google Ads?
Microsoft Advertising has significantly lower search volume than Google, which means fewer advertisers competing for the same keywords. Less competition drives down cost-per-click. That said, lower CPC is only valuable if there is sufficient search volume in your sector to generate meaningful traffic.
Can AI management replace a bing advertising agency?
AI management is currently most effective for Google Ads, where the data volume and account structure justify automated daily optimisation. For Bing, AI tools exist but the lower volume makes the case less compelling. For most SMEs, getting Google managed well by an AI agent delivers more return than splitting attention between Google and a bing advertising agency.
