How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A Microsoft Advertising agency — most buyers still say Bing Ads — runs paid search on Microsoft's network rather than Google's: the account build and the Google Ads import, keywords and audiences across Bing, Yahoo, DuckDuckGo and Copilot Search, Audience Network placements, Shopping feeds, and the LinkedIn company, industry and job-function targeting that exists nowhere else in search.

Nine agencies serving London passed our evidence check, judged only on what their own sites say about Microsoft Advertising or Bing Ads rather than paid search in general. Six print a London street address, four name clients, and none of them publishes a rate we could verify on its own site. Where a firm sits outside the city, we say so.
Are London Microsoft Advertising agencies really based in London?
Six of the nine external agencies on this page publish a London street address, from City Road to Hatton Garden and Mayfair. One is in Twickenham, one is a national UK network, and one names the city without printing an address.
1. Web Tonic
About: Web Tonic runs Microsoft Advertising inside one growth programme, so the Bing account is planned against the same targets as the Google paid search and reconciled in one reporting layer rather than reported on its own. London briefs almost always arrive with a mature Google account attached, so we agree what the Microsoft account is for, incremental reach or cheaper repeat demand, before a single campaign is imported. A company that only needs an existing Microsoft account tidied or a feed fixed will be well served by several of the specialists below.

Frequently Asked Questions
Why run Microsoft Advertising at all when Google is so much bigger in the UK?
Because the cheap half of your demand is often sitting on desktop. StatCounter measured Bing at 4.47% of worldwide search in July 2026 but 8.84% on desktop, and desktop is where most B2B and high-value research still happens. In London that skews towards finance, legal, recruitment and B2B software buyers researching from a work machine, frequently on Edge with Bing as the untouched default. The volume will never rival Google, but the auction is thinner, so the same keyword usually clears at a lower cost per click and a better cost per qualified enquiry.
Six of nine publish a London address. Does an office actually matter here?
Less than for creative work, more than agencies admit for planning. Pearl Lemon on City Road, The Good Marketer on Whitechapel Road, Found in Hatton Garden, Nautilus Marketing on Albert Embankment, London Marketing Company in Mayfair and Reload Digital all publish London addresses. The account itself is managed remotely regardless. What proximity buys is attendance at the quarterly review where budget is argued over, which is where most Microsoft spend is won or lost.
Our agency says it will just import the Google campaigns. Is that enough?
It is a start, and it is where most London accounts stop. The Google Ads import runs in minutes, which is exactly why so many Microsoft accounts are neglected: the import is treated as the strategy instead of the starting point. Match types behave differently, the audience network is a separate discipline, LinkedIn profile targeting has no Google equivalent, and negative lists imported wholesale usually strangle volume that never needed strangling. Ask what changes in the first ninety days after the import, and who reviews the search terms weekly.
Four of the nine name clients. How much should that count?
Enough to shortlist, not enough to sign. Nautilus Marketing credits the European Commission, Swindon Borough Council and On the Beach; Reload Digital names Wrangler, Lee and New Era; Disturb Digital lists Matchroom Boxing and Yash Raj Films International; LOCALiQ names smaller local advertisers. Published logos prove a relationship existed, not that the same team still runs the account. Ask each firm for two contactable references at a similar spend level in your sector.
What does Microsoft Advertising management cost in London?
None of the nine publishes a rate we could verify on its own site, and London quotes range from a percentage of spend to a flat retainer. Ask every shortlisted firm for three separate lines against one identical brief: the audit of the existing account, the rebuild work, and the ongoing management. Only the third genuinely recurs. Keep the Microsoft Advertising account, the UET tag and the Merchant Center feed in your own company's name.
Choosing a Microsoft Advertising Agency in London
Six of the nine are London firms. This is a genuinely resident bench rather than a national network answering a London postcode, and we named the real base of the three that sit elsewhere.
Desktop share is the argument, not total share. Bing's 8.84% desktop share matters far more to a London B2B advertiser than its 4.47% overall, and any proposal that leads with the smaller number has not thought about your buyers.
The Google import is the start of the work. Ask what changes in the ninety days after it, who reads search terms weekly, and whether LinkedIn profile targeting and the Audience Network are being used at all.
Nobody publishes a verifiable rate. Quote the audit, the rebuild and the ongoing management as three lines against one brief, and keep the account, the UET tag and the feed in your own name. If you would rather have the Microsoft account, the paid search and the organic work answering to one number, read our latest analysis or see how we work in London.
