Most small businesses exploring bing advertising agencies are already running Google Ads and wondering whether Microsoft Advertising deserves a slice of their budget too. It is a fair question, and the answer is more nuanced than most agency websites will tell you.
This article explains what bing advertising agencies actually do, how they compare to Google-first options, and why an AI agent managing your paid search might serve your budget better than a traditional retainer.
What Bing Advertising Agencies Actually Do
Bing advertising agencies manage paid search campaigns on Microsoft Advertising — the network that covers Bing, Yahoo, and a portion of DuckDuckGo search results. The core work involves keyword selection, bid management, ad copywriting, audience targeting, and monthly reporting. On paper, it looks identical to Google Ads management. In practice, the differences matter quite a lot.
Microsoft Advertising's auction system is less competitive than Google's, which means cost-per-click tends to be lower. For certain industries — B2B software, financial services, legal — the Bing audience skews older and more affluent, which can produce better conversion rates despite lower traffic volume. After nine years running a marketing agency, we saw this pattern repeatedly: clients who dismissed Bing changed their minds after seeing the CPA comparisons side by side.
That said, bing advertising agencies face a structural problem. Microsoft Advertising generates significantly less search volume than Google, so the management overhead relative to the budget spend is disproportionate. An agency charging a percentage of spend has less incentive to prioritise a smaller Bing account when the Google account generates ten times the revenue.
Understanding what a paid search service actually does before you engage any agency — Bing-focused or otherwise — will save you a difficult conversation three months into a retainer.
How Bing Advertising Agencies Compare to Google-First Options
The search advertising market is not evenly split. Google holds roughly 90% of global search volume, and most PPC agency services are built around that reality. Agencies that position themselves specifically as bing advertising agencies are a relatively small subset of the market, and their quality varies considerably.
Here is a practical comparison of the main options available to SMEs managing paid search in 2026:
| Option | Typical Monthly Cost | Bing Coverage | Google Coverage | Reporting Frequency |
|---|---|---|---|---|
| Specialist Bing agency | £800–£2,500 | Full | Limited or none | Monthly |
| Full-service PPC agency | £1,200–£5,000+ | Often secondary | Primary | Monthly |
| Freelance PPC consultant | £500–£1,800 | Depends on individual | Usually primary | Monthly or ad hoc |
| AI agent (Google Ads) | From £299/month | No | Full | Weekly summaries |
The table above reflects typical UK market rates. If your primary concern is Google Ads — which it should be for most SMEs given the volume differential — a specialist Bing agency may not be the right match. For a deeper look at how costs stack up on the Google side, what SMEs actually pay for Google Ads is worth reading before you commit to any retainer.
One thing bing advertising agencies rarely mention upfront: Microsoft Advertising allows you to import campaigns directly from Google Ads. If your Google account is well-structured, setting up a Bing presence does not require a specialist agency. It requires a competent operator and an hour of their time.
Should SMEs Use Bing Advertising Agencies at All
This is where we will give you an honest answer rather than a diplomatic one. For most SMEs with monthly paid search budgets under £5,000, running a separate retainer with bing advertising agencies alongside a Google Ads manager is rarely justified. The management fees eat into a budget that could be better concentrated on the channel with the most volume.
The exception is niche B2B sectors where the Bing demographic genuinely outperforms. If you sell enterprise software, accounting services, or legal advice to decision-makers over 45, Microsoft Advertising deserves serious attention. The audience self-selects in ways that Google's broader reach does not always replicate.
For most other SMEs — local service businesses, ecommerce, hospitality — the priority should be getting Google Ads right first. Google Pay Per Click Management remains the highest-leverage paid search activity for the majority of small businesses, and it is where operational discipline produces the most measurable returns.
Once your Google account is profitable and stable, adding Bing through a direct Microsoft Advertising account or a multi-channel agency becomes a rational next step rather than a distraction.
What Good Paid Search Management Looks Like
Whether you are working with bing advertising agencies, a Google-specialist, or evaluating alternatives, the operational markers of good paid search management are consistent. The account should be reviewed more than once a month. Underperforming keywords should be paused, not left running because nobody checked. Budget should shift toward what is working, not remain fixed because that is how it was set up in month one.
In practice, many SMEs discover that their agency reviews the account monthly at best. The Google Ads interface contains enough data to fill a working day, and most agencies are managing dozens of accounts simultaneously. The attention your £1,500-a-month account receives is not the same as the attention a £15,000 account receives. This is not a criticism — it is a structural reality of agency economics.
How to fix high cost per acquisition in Google Ads is often less about strategy and more about the frequency of optimisation. Accounts that are reviewed and adjusted weekly consistently outperform those reviewed monthly, even when the underlying strategy is identical.
Operational specifics matter here. Bid adjustments for device, time of day, and audience segment should happen regularly. Search term reports should be mined weekly for negative keyword additions. Ad schedule data should inform when budget is active. These are not advanced tactics — they are table stakes, and they require consistent attention that most SME accounts do not receive.

Why AI Agents Are Changing the Calculation
The traditional choice for SMEs has been agency or DIY. Bing advertising agencies, Google specialists, freelancers — all require the same thing: a human operator checking in periodically and making adjustments. The quality of that operator and the frequency of their attention determines your results.
An AI agent changes this by removing the periodic check-in model entirely. Rather than a monthly review, the account is monitored continuously. Bids adjust based on performance signals. Underperforming ad groups are paused. Budget reallocates toward campaigns that are converting. A summary lands in your inbox so you know what changed and why.
This is not about removing human judgement from paid search — it is about applying consistent operational discipline at a frequency no human retainer model can match at SME price points. Compare your options on the pricing page to understand where this sits relative to agency fees.
The limitation worth acknowledging: AI agents managing Google Ads do not currently cover Microsoft Advertising. If Bing is genuinely important to your sector, you still need a human operator for that channel. The question is whether you need bing advertising agencies for both channels, or whether Google handled well produces enough return that Bing becomes a secondary consideration.
For most SMEs, the honest answer is the latter. Understanding whether a PPC agency or AI agent fits your needs is a useful exercise before committing budget either way.
What to Look For in Bing Advertising Agencies
If your sector or budget justifies working with bing advertising agencies, the evaluation criteria are specific. Ask how frequently the account will be reviewed — monthly is not sufficient. Ask whether the agency manages Microsoft Advertising natively or imports from Google and leaves it. Ask what their process is for negative keyword management, because this is where Bing accounts bleed budget most visibly.
Certification is table stakes, not a differentiator. Microsoft Advertising has its own accreditation programme, and any agency positioning itself as a Bing specialist should hold it. What matters more is whether the person who holds the certification is the person actually working on your account.
Agency size is a real factor. A boutique agency with ten clients gives your account more attention than a large agency with three hundred. This is not always reflected in the fee structure, which is why asking directly about account management ratios matters. After nine years in agency life, the single most predictable indicator of account performance was how many accounts each executive managed — not the agency's client roster or their award history.
Also consider whether you need bing advertising agencies as a standalone engagement, or whether a full paid search management service covering both Google and Bing makes more operational sense for your budget.
The Honest Position on Bing for SMEs in 2026
Bing is not irrelevant. For the right business in the right sector, Microsoft Advertising delivers returns that justify the management overhead. But bing advertising agencies are a specialist solution to a specific problem, and most SMEs do not have that specific problem yet.
If you are spending under £3,000 a month on paid search and your Google Ads account is not yet consistently profitable, allocating budget and management attention to Bing is premature. Fix Google first. Once that channel is working — meaning your CPA is within target, your Quality Scores are healthy, and your negative keyword list is actually maintained — then the conversation about Bing becomes productive.
The best next step today is to review how your Google Ads account is managed and identify where optimisation gaps exist. Overtime, the AI agent that manages Google Ads accounts for SMEs, handles the operational work — adjusting bids, pausing underperformers, reallocating budget — so that your Google foundation is solid before you consider adding channels. Understanding what SMEs actually get from AI PPC management is a practical starting point before evaluating bing advertising agencies or any other specialist provider.

Frequently Asked Questions
What do bing advertising agencies charge for Microsoft Advertising management?
Most bing advertising agencies charge either a flat monthly retainer or a percentage of ad spend, typically between 10% and 20%. For SME budgets, flat retainers usually start around £500–£800 per month for Bing-only management, though pricing varies considerably depending on account complexity and the agency's size.
How does Microsoft Advertising differ from Google Ads for SMEs?
Microsoft Advertising typically delivers lower cost-per-click than Google due to reduced competition, but also significantly lower search volume. For SMEs, this means Bing can produce efficient results in specific sectors — particularly B2B and professional services — but rarely generates the same scale of traffic as Google Ads.
Should I use bing advertising agencies before fixing my Google Ads?
No. Google Ads should be your priority if you are spending under £5,000 a month on paid search. Bing adds a secondary channel that depends on the same account structure discipline as Google. If your Google account is underperforming, adding Bing management overhead does not solve the underlying problem.
Can I run Microsoft Advertising without a specialist agency?
Yes. Microsoft Advertising allows direct import from Google Ads, which means a well-structured Google account can be replicated on Bing relatively quickly. You do not need a specialist agency to get started, though ongoing optimisation — particularly negative keyword management — requires regular attention from a competent operator.

What questions should I ask bing advertising agencies before signing?
Ask how frequently your account will be actively reviewed, what their process is for search term analysis and negative keywords, and how many accounts each account manager handles. The ratio of accounts to managers is one of the most reliable indicators of the attention your account will actually receive.
