Google Business Profile: The 80/20 Optimisation Guide

For most UK small businesses, the Google Business Profile (GBP) is the highest-leverage marketing asset they own — it decides whether you appear in the map pack, what a customer sees before they ring, and increasingly what AI assistants say about you. Yet most profiles are 60% complete and optimised in the wrong order. Here is where the leverage actually sits.

Your primary category is the single biggest lever

No other field comes close. Your primary category tells Google which searches you are a candidate for, and changing it can move you in or out of the map pack overnight. Google maintains roughly 4,000 categories, and precision pays: “Emergency plumber” competes in different results from “Plumber”; “Letting agent” from “Estate agent”; “Cosmetic dentist” from “Dentist”.

1. Search your most valuable phrase — the one a ready-to-buy customer types — in your own town.
2. Note the primary category of the three map-pack businesses (it is shown on each profile, or visible via a free tool such as GMBspy).
3. Match it. If the winners for “boiler repair southampton” all use “Heating contractor” and you use “Plumber”, that is your first fix.

Then add secondary categories for every service you genuinely offer — a plumber might add “Heating contractor”, “Bathroom remodeler” and “Drainage service”. Secondaries carry less weight than the primary but widen the searches you can appear for. Add only what you truly do; a category you cannot service invites the wrong calls and the occasional one-star review.

Fill in Services and Products — Google reads them

Under Edit services, Google suggests pre-defined service names for your categories — accept every relevant one, because these map directly to known search queries — then add custom services with a one or two sentence description and a price or “from” price where you can. Profiles with detailed services can surface for service-specific searches the business name alone would never match.

The Products section (Edit products) is not just for retailers. Service businesses use product cards effectively as offer tiles with photos and prices — “Boiler service — £85”, “Gas safety certificate (CP12) — £60”. They appear prominently on your profile on mobile and are some of the most clicked elements on it. Pricing transparency here filters out bargain-hunters before they ring.

Photos: the most under-used field on the profile

Photo count correlates with action more strongly than almost any other profile element. BrightLocal’s analysis of 45,000 business profiles found businesses with more than 100 images received 520% more calls and 2,717% more direction requests than the average business. Correlation is not causation — active businesses take more photos — but customers demonstrably act on profiles they can see inside.

You do not need a photographer. Add a handful of genuine photos each month: jobs in progress, finished work, your van, your team, the premises inside and out. Real and recent beats polished and stale — and a steady trickle signals an active business in a way a one-off upload never can.

Google posts and Q&A: small effort, visible profile

Updates (formerly Google Posts, under Add update) show on your profile for about six months and give you control over fresh content there: a recent job, a seasonal reminder, an offer with a Call now or Book online button. There is no strong evidence posts move rankings, but they occupy profile space that would otherwise sit empty, and they convert lookers into callers. One post a fortnight is plenty.

The Q&A section is public and anyone can ask — or answer — questions on your profile. Seed it yourself: from your business account, post the five questions you answer on the phone every week (“Do you charge a call-out fee?”, “Are you Gas Safe registered?”, “Do you work weekends?”) and answer them. You are not gaming anything; you are pre-answering real buying questions in a space a competitor or stranger could otherwise fill. The same questions, on your website, make strong FAQ content for AI search visibility.

Reply to reviews — and let the keywords come naturally

Reviews factor into rankings; replies factor into conversions. Reply to every review within a few days. In positive replies, naturally restate the service and place — “Glad we could sort the boiler installation in Didsbury so quickly” — because review content and replies are text Google associates with your profile. Naturally is the operative word: one mention, written for the customer, not a keyword list. Stuffed replies read as exactly what they are.

For negative reviews, a short, factual, non-defensive reply that offers to put things right is read by hundreds of future customers and does more for trust than the five-star reviews around it.

What does not matter (and what gets profiles suspended)

The 80/20 cuts both ways. Things not worth your time: obsessing over the 750-character business description (read by humans, little ranking weight), adding every attribute, daily posting, or buying citation packages by the hundred.

One tactic deserves a stronger warning. Adding keywords or place names to your business name — “Smith Plumbing | Emergency Plumber Leeds” when the sign on your van says Smith Plumbing — works, which is why people do it, and it directly violates Google’s business name guidelines. Your real-world name only. Google suspends profiles for it, competitors can report it with the “Suggest an edit” button, and a suspension takes your reviews, photos and rankings offline for weeks while you appeal. The lever is large and so is the downside; leave it alone.

Measure what changed

The Performance tab in your profile shows calls, direction requests, website clicks and the searches that surfaced you — check it monthly, and watch the split between discovery searches (“plumber near me”) and branded ones (“smith plumbing”). Discovery growth is the optimisation working. Pair it with Search Console for the website side; our Search Console quick wins guide shows what to look for first. Category choices and service names vary a lot by trade — our industry SEO guides cover the specifics.

This is also the kind of work Vantage agents handle from live data: cross-referencing your Search Console queries against your profile’s categories and services, and flagging the specific gaps — a missing secondary category, a service customers search for that your profile never mentions — rather than a generic to-do list.
