The London map pack, measured — not guessed
Most "local SEO in London" pages tell you the city is competitive and leave it there. We measured it instead: 300 live Google Maps listings across 15 real searches — plumber to conveyancing solicitor — captured from the centre of London twice, 24 hours apart, as part of our UK map-pack study.
What came back is not the story the sales pitches tell. London is two cities at once: consumer packs where the median top-3 listing carries thousands of reviews, and trade packs won by profiles with one review — or none.
This page is the evidence. If you're past researching and weighing up who should act on it, our local SEO for London businesses page covers what we do, who it suits and how the engagement works — a Maps specialist, not a bundled "SEO agency London" retainer.
In short
London's map pack is two markets in one. Restaurant and dentist packs demand serious review depth (median 5,228 and 294 reviews respectively in our captures), while locksmith, electrician and accountant packs were held with almost none. Across all 15 searches the top 3 actually carried fewer median reviews (38) than ranks 4–20 (45) — in a city this dense, proximity and relevance outweigh raw review count. Where you compete decides everything.

Where London is brutal — and where it's wide open
The averages above hide the real story: the review bar swings by three orders of magnitude depending on the search. This is the median review count of the top-3 listings for each search we captured in London.

Three honest observations from the London capture
Review count isn't what decides a London pack
Across our 15 searches, the median top-3 listing carried 38 reviews — fewer than the 45 of ranks 4–20. That inversion almost never makes it into a sales pitch, but it matches how Google works in a dense city: with thousands of candidates within a mile, proximity and category relevance can outrank raw review depth. The practical read: being the right business in the right place beats buying review volume — and no agency promising "more reviews = top 3" in London is being straight with you.
Trade and professional packs are startlingly thin
The locksmith pack we captured was held with a median of 1 review. Electrician: 2. Accountant: 0 — and 5 of London's 45 top-3 seats had no rating at all. For trades and professions, the London map pack is not a fortress; it's an open door that most businesses simply haven't walked through with a complete, well-categorised profile.
The pack moves — even overnight
3 of the 15 London packs we tracked changed membership within 24 hours. A single rank check tells you where you stood for one moment, from one point in the city. That's why we measure against a day-0 baseline and track movement monthly rather than selling you a screenshot.
What this means if you trade in London
- ✓Check your search family in the table first — a restaurant's fight and a locksmith's fight are different sports in this city.
- ✓In thin packs (trades, professions), a complete claimed profile with the right categories can be most of the battle.
- ✓In heavy packs (restaurants, dentists), review depth is a multi-year moat — start now or compete on a more specific search.
- ✓The top 3 carrying fewer reviews than ranks 4–20 means optimisation, not volume, is London's real lever.
- ✓Packs churn within a day — judge progress against a recorded baseline, not a one-off screenshot.

London questions, straight answers
Is local SEO harder in London than elsewhere in the UK? +
It depends entirely on your search family, not the city as a whole. In our capture London's restaurant pack demanded a median 5,228 reviews — the highest we measured anywhere — while its locksmith, electrician and accountant packs were held with 0-2 reviews. For most trades and professions, London's pack was no harder to enter than smaller cities'; for consumer categories it's the hardest in the country.
How many reviews do I need to reach the top 3 in London? +
There is no single number, and our data shows the top 3 actually carried fewer median reviews (38) than ranks 4-20 (45) across London searches. Check the table above for your search family: it ranges from 0 (accountant) to 5,228 (restaurant). Review depth matters most in consumer categories; in trades, profile completeness and relevance did the heavier lifting.
Does the London map pack change often? +
3 of the 15 London packs we tracked changed membership within a single 24-hour window. Movement is normal — which is why we record a day-0 baseline for every keyword we track and measure monthly against it, instead of judging by one screenshot.
My business is in a London borough, not the centre — do these numbers apply? +
Directionally yes, precisely no. Our captures were taken from central London at zoom level 14; packs re-rank as the searcher moves, and a borough pack is its own contest. The pattern that transfers is the split between heavy consumer packs and thin trade packs. Your own baseline — which we record on day one — is the number that actually matters.
