Google Business Profile is the single highest-leverage free marketing channel a UK small business has. A complete, well-managed profile routinely outranks larger competitors with thinner profiles in the local-pack three-pack, and the lift compounds — more views feed more interactions feed more relevance signals feed higher ranking. The frustrating reality is that most profiles are filled to 30-40% of completeness, and the gap between that and a fully optimised profile is exactly where the local-pack ranking opportunity lives.
What "optimisation" actually means in 2026
Eleven distinct signal categories Google reads off a Business Profile. (1) Primary category. (2) Secondary categories. (3) Attributes. (4) Services. (5) Products. (6) Photos. (7) Posts. (8) Reviews. (9) Q&A. (10) Messaging. (11) Bookings. Each is a ranking signal in its own right, and the cumulative effect of completing all eleven is materially larger than the sum of any individual signal. Most profiles we audit complete three or four of the eleven; the profiles that complete nine or eleven of them dominate the three-pack on the relevant queries.
1. Primary category — pick the highest-revenue specific
The primary category is the single most consequential field on the profile because Google uses it to determine which queries you are eligible to appear on. Pick the most specific category that matches your single highest-revenue service. "Restaurant" is too broad; "Italian Restaurant" is more specific and more eligible. "Plumber" is acceptable; "Emergency Plumber" or "Gas Plumber" is more specific where applicable. Re-pick this if your business focus has shifted — many established profiles still carry the original primary category from years ago when the business looked different.
2. Secondary categories — up to nine, all relevant
Google allows up to nine secondary categories. Use them all where the business genuinely serves them. A multi-service trade business should list every service line as a secondary category; a restaurant should list every cuisine variant relevant to its menu; a salon should list every treatment category it offers. Each secondary category adds to the eligibility set without diluting the primary, provided each is genuinely accurate. Inaccurate or stretched categories are penalised once Google detects the mismatch via user signals.
3. Attributes — fill every applicable one
Attributes are the structured tags Google offers under the profile editor — accessibility, identity, planning, payments, dining options, parking, amenities. Most profiles complete five or six attributes; the available list is typically 30-50 depending on category. Each attribute is a separate filter Google can match against, and missing attributes mean missing visibility on queries that include those filters ("wheelchair accessible restaurant near me", "vegan-friendly cafe [city]", "free parking dentist [postcode]").
4. Services — list every service line with a description and price-from
The Services module lets you list each service the business provides with a short description and a price-from where you choose to publish. This is one of the most under-used features and one of the highest-leverage. Each service is searchable and is surfaced in the profile detail view; multi-service businesses gain visibility on every service-specific query they list correctly. The price-from field is optional but materially lifts click-through where you can publish a number — searchers self-qualify on price before they ever click through.
5. Products — for retail-led profiles, every meaningful product
The Products module is for businesses with discrete products — retail, e-commerce, cafes with signature items, salons with signature treatments. Each product gets a photo, a title, a description, and a price. Up to thousands of products are supported in principle; most profiles benefit from listing the 10-30 highest-revenue or most-distinctive products. The Products listing is surfaced both in the profile detail and increasingly in standalone product-related search results.
6. Photos — the 30-image baseline plus the fortnightly cadence
A complete profile carries at least 30 photos at the baseline — a cover photo, an interior set, an exterior set, a team set, a product or service set, and recent work where applicable. After the baseline, add two photos per fortnight on an ongoing basis. The fortnightly cadence is a freshness signal Google reads as "this business is active"; profiles that haven’t had a new photo in six months are penalised compared to profiles that update every two weeks. Photo quality matters more than quantity past the baseline — a single well-shot photo outperforms five amateur photos.
7. Posts — weekly cadence, structured types
GBP Posts are short content items (text plus optional photo, optional CTA) that appear on the profile and surface in local-pack results for the first 7-14 days after publication. There are four post types — Update, Offer, Event, Product. Most businesses post nothing; profiles that post weekly across the four types see measurable lift in profile views and direct interactions. The posts decay after 7-14 days, so the cadence has to be ongoing rather than a one-off campaign.
8. Reviews — same-day asked, branded, friction-free
The single most consequential ongoing ranking signal. The pattern that works: same-day asked, branded, friction-free. Same-day means you ask while the work is fresh — review request conversion drops by half if you wait a week. Branded means the request is personal (a text from the engineer or technician, named, with a line about the specific job) not a generic email blast. Friction-free means the customer is one tap from the five-star button — a short URL on your domain (yourdomain.com/review) that 301s straight to your GBP review form. Conversion rates: 24-35% on texted same-day requests, 4-9% on emailed week-later requests. Reply to every review within 48 hours.
9. Q&A — pre-populate, do not let competitors do it for you
Anyone can ask a question on your GBP and anyone can answer. Most profiles let the Q&A section fill with random questions and the occasional unhelpful answer from a stranger. Pre-populate it instead. Ask the obvious questions yourself (do you take walk-ins, is parking free, what time do you close on bank holidays, do you serve vegan options) and answer them as the business — clear, accurate, authoritative. Eight to fifteen pre-populated Q&As covering the questions you genuinely receive removes the surface area for unhelpful third-party answers and surfaces the answers as structured content Google can use in local-pack snippets.
10. Messaging — enable it if you will respond within an hour
GBP Messaging lets searchers message the business directly from the profile. Google penalises profiles with messaging enabled that do not respond within Google’s expected window (typically four hours, weighted more strongly during business hours). Enable it only if you will genuinely respond within an hour during business hours. The lift on profiles that respond promptly is meaningful; the penalty on profiles that respond slowly is also meaningful, and the latter outweighs the former.
11. Bookings — wire the booking integration
For businesses that use a supported booking platform (Resy, OpenTable, ResDiary, Mindbody, Booksy, Treatwell, many others), the GBP Bookings integration surfaces the booking widget directly on the profile. This shortens the path from search to booking by a measurable margin and is read by Google as a positive interaction signal. The integration is configured inside the booking platform; once enabled, the booking module appears on the profile automatically.
The cadence summary
Photos: two per fortnight. Posts: one per week across the four post types. Reviews: every customer asked on the day. Q&A: top eight to fifteen questions pre-populated and maintained. Insights review: monthly, watching for the queries you appear on and the proportion of "Discovery" searches (people who found you through category-led search rather than branded search) versus "Direct" searches. The cadence is the operational discipline; the categories above are the structure the discipline applies to.
What does not move ranking (and what people spend money on)
Three things owners pay for that do not move local-pack ranking. (1) Paid GBP "optimisation" services that promise to "submit" your profile to extra directories — Google does not read those signals for the local pack. (2) Buying reviews — Google detects review patterns aggressively and penalises profiles found to be buying. (3) Backlink packages targeting the GBP listing — backlinks do not affect GBP ranking the way they affect organic ranking. The free, structured work above is what moves the needle.
