Most advice about ranking your business in Google Maps is opinion dressed up as fact. So when someone analyzes 1.8 million Google Business Profiles and publishes the correlations, it's worth paying attention — not because a big dataset makes every claim true, but because it lets us separate the signals that consistently line up with better local SEO rankings from the ones marketers merely assume matter.
That's what local-search firm Whitespark did. In a study of 1.8 million profiles across 4,209 business categories, reported by Search Engine Land, the team measured how category choice and profile completeness correlate with where a business lands in local results. Paired with Whitespark's annual ranking-factors survey — summarized by BrightLocal — the picture is clearer than usual: a handful of profile decisions explain a lot of the ranking gap between businesses that show up and businesses that don't.
Here's the honest translation for a small-business owner in Northeast Indiana who doesn't have time to read a data study — what actually moves the needle, what's table stakes, and what's noise.
Key Takeaways
- Whitespark's analysis of 1.8 million Google Business Profiles found primary category to be the single strongest lever — specific categories correlated with roughly a third more top-10 presence than generic ones.
- Google Business Profile signals account for the largest share of local-pack ranking weight (about 32%), followed by review signals (~20%), per Whitespark's ranking-factors survey.
- Profile completeness matters: profiles scoring full marks on core fields averaged ~19 positions higher and roughly triple the top-10 presence of empty profiles.
- Additional categories, review recency, and NAP consistency are cheap wins most local businesses leave on the table.
- Correlation is not causation. A well-optimized profile is table stakes for visibility — not a guarantee of ranking, and not a substitute for your website and reviews.
- The same rules apply whether you're a Fort Wayne HVAC company or an Allen County law firm; the categories and competitors just change.
What Did Whitespark Actually Study — and How Should You Read It?
The dataset is large, but the method matters more than the size. Whitespark pulled 1.8 million Google Business Profiles across 4,209 categories and looked at how two things — the categories a business chooses and how completely it fills out its profile — correlate with average ranking position and how often a profile appears in the top 10 local results, according to Search Engine Land's write-up of the research.
The critical word is correlate. This is observational data, not a controlled experiment. A plumber ranking well with a complete profile might rank well because the profile is complete — or because that same diligent owner also earns more reviews, keeps NAP data consistent, and runs a better website. The study can tell you what winners tend to have in common. It can't prove that copying one attribute in isolation will move you up. We read studies like this the way we read weather data: strong patterns worth acting on, not promises.
That framing keeps you honest and saves money. It means you treat profile optimization as the foundation — the thing you get right before you spend on anything else — rather than a magic switch. If you want the fuller local-search picture beyond the profile, we cover it in our guide to Fort Wayne SEO in 2026; this post zooms in on the profile itself.
Which Local SEO Ranking Factors Carry the Most Weight?
Whitespark's separate annual ranking-factors survey — where local SEO practitioners score the relative influence of each signal — gives a useful weighting. As BrightLocal summarizes, the signal groups for the local pack break down roughly like this:
| Signal group | Approx. share of local-pack weight | What it covers |
|---|---|---|
| Google Business Profile | ~32% | Primary category, additional categories, keywords in the business name, proximity, completeness |
| Reviews | ~20% | Quantity, star rating, recency, velocity, native text reviews |
| On-page | ~15% | Your website's content, NAP, location/service pages |
| Behavioral | ~9% | Clickthrough rate from local results, engagement signals |
| Links | ~8% | Inbound links to your site |
| Citations | ~6% | Consistent listings across directories |
Two things jump out. First, the profile itself is the biggest single bucket — which is exactly why a study of profiles is so useful. Second, reviews and your own website together rival the profile's weight, so a beautiful profile attached to a thin website and no reviews still under-performs.
Within the profile group, BrightLocal's ranking of the top individual local-pack factors puts primary category first, followed by proximity of your address to the searcher, keywords in your business title, whether you're open at search time, star rating, additional categories, native reviews with text, and review recency. Proximity is the uncomfortable one: you can't move your building, so for searches physically far from you, ranking gets harder no matter how perfect the profile. That's a limitation worth being honest about — profile work widens your radius, it doesn't erase geography.
It's also worth noticing what isn't near the top of that list. Behavioral signals — how often people actually click your result, call, or ask for directions — carry meaningful weight (roughly 9%), and they're downstream of everything else. A sharp business name, a strong primary photo, and a rating that stands out all earn clicks, and those clicks appear to reinforce your position. In other words, the profile isn't just a ranking form to fill out; it's a storefront that has to earn the tap once it shows up. Optimizing for the algorithm and optimizing for the human who sees the result are, increasingly, the same job.
How Much Does Your Primary Category Really Matter?
More than almost anything else you control. In Whitespark's survey, primary category ranks as the number-one local-pack factor, and choosing the wrong primary category is cited as the most impactful negative signal you can inflict on yourself.
The 1.8-million-profile data puts numbers to it. Profiles using a specific primary category appeared in the top 10 about 12.5% of the time, versus 9.2% for those using a generic category — roughly a third more top-10 presence, per the study findings. The category-level examples are stark:
| Specific category (avg. rank) | Generic category (avg. rank) |
|---|---|
| Criminal justice attorney (44.7) | Attorney (57.1) |
| Electrician (48.6) | Contractor (57.7) |
| Tapas restaurant (28.8) | Restaurant (49.7) |
Lower average-rank numbers are better. In each pairing, the more specific label correlated with a meaningfully stronger position. The lesson isn't to invent a category — Google only lets you pick from its list — it's to pick the most precise option that genuinely describes your core business, then not stop there.
Additional categories are the second half of the play. Whitespark found that well-chosen supplementary categories correlated with rankings 6 to 17 positions better than profiles carrying only a primary category, with strong pairings like veterinarian + emergency veterinarian service or electrician + EV charging station contractor. If your business legitimately offers a service, there's usually a category for it — and leaving it off is free ranking you're declining. This is also where relevance for AI answer engines starts, since the same structured signals feed LLM-based local results; we dig into that in Local SEO for LLMs.
Does a Complete Google Business Profile Change Your Rank?
The completeness data is the part most owners underestimate. Whitespark scored profiles 0–5 on five core fields — website, business description, hours, photos, and claimed status — and the correlation with position was clean:
| Completeness score | Avg. ranking position | Top-10 presence |
|---|---|---|
| 0 (empty) | ~62 | ~4% |
| 5 (complete) | ~43 | ~13% |
That's roughly 19 positions of difference and about triple the top-10 presence between an empty profile and a fully filled one, according to the study. Again, correlation — the diligent owner effect is real — but the fields cost nothing but an afternoon.
There's also a competitive-context wrinkle the data surfaced. Average completeness varies by industry: home-services businesses averaged 4.4/5 (about 55% fully complete) and professional services 4.3/5 (52%), while community organizations sat at 3.0/5 (about 22%). Translation: in a category where everyone's profile is already polished — like HVAC or plumbing — completeness is just the ante to sit at the table, and you'll need reviews and website strength to actually win. In a category where profiles are sloppy, simply finishing yours can be a genuine edge. Third-party analysis backs the direction: a Localo study of 2 million profiles, cited by Blogging Wizard, found businesses in the top three positions averaged completed descriptions far more often than lower-ranked ones (about 75% had them), alongside far larger review and photo counts.
How Do Reviews and Photos Fit Into the Picture?
Reviews are the second-heaviest signal group for a reason, and they're the one part of your profile customers actively judge. Nearly nine in ten consumers read online reviews for local businesses, and about 89% say they're more likely to use a business that responds to all of its reviews, per Digital Applied's 2026 local SEO roundup. The ranking-factor surveys reinforce that it's not just star rating — recency and a steady velocity of new reviews carry weight, which is why a business with 300 reviews from three years ago can lose to a competitor earning a handful every week.
The Localo data adds texture: top-three businesses averaged roughly 250 reviews and 250+ photos on their profiles, with review responses averaging around 140 words, as compiled in that same Blogging Wizard roundup. You don't need to hit those numbers to compete locally in a smaller market, but the direction is unmistakable — more genuine reviews, answered thoughtfully, and a steady stream of real photos. Digital Applied's roundup even reports profiles that refresh photos monthly see materially more direction requests. We'd treat the exact percentages as directional rather than gospel, but the behavior is sound and free.
A caution rooted in our honesty rule: never buy, gate, or fabricate reviews, and never ask only happy customers. Beyond violating Google's policies and risking suspension, it corrupts the exact signal you're trying to build. Regulated fields have extra landmines — for medical and dental practices, a careless public reply can create a HIPAA problem, which we walk through in Fort Wayne healthcare reviews and HIPAA. For the broader connection between reviews, rankings, and AI answers, see how reviews shape SEO and AI visibility.
What Does This Mean for a Fort Wayne or Northeast Indiana Business?
None of these signals care that you're in Allen County — but your competitive context does. Take a Fort Wayne HVAC company. In home services, the study says nearly everyone's profile is already complete, so “finish your profile” won't lift you past established competitors on its own. Your realistic edges are precise categories (HVAC contractor plus legitimately applicable additions like furnace repair service or air conditioning contractor), a faster website, and a steady drip of recent, text-rich reviews from real jobs across Fort Wayne, New Haven, and Auburn.
Now take a DeKalb County nonprofit or a niche trades business, where the data shows profiles are often half-finished. There, simply claiming the profile, choosing the most specific category, adding hours and a real description, and posting current photos can meaningfully outrank neighbors who never bothered.
Two local realities deserve extra care. Proximity means a single Auburn location won't rank the same in downtown Fort Wayne as a business physically there — chasing every surrounding town with thin, duplicated pages usually backfires, which is why we take a conservative stance in Fort Wayne multi-location SEO. And because your profile is now this load-bearing, protect it: a suspension or a lost admin can erase your visibility overnight, so build a Google Business Profile continuity plan before you need one.
Where to Start This Week
If you do nothing else, do this, in order: confirm your primary category is the most specific accurate option; add every legitimate additional category; fill all five completeness fields (website, description, hours, photos, claimed status); make sure your Name, Address, and Phone match exactly between your profile and your website — BrightLocal's analysis ties consistent NAP to a materially higher chance of appearing in the local pack; then start a simple, ongoing routine of asking every satisfied customer for a review and replying to each one.
Then make it a habit, not a one-time project. Google rewards active profiles, so set a recurring reminder to add a few fresh photos each month — Digital Applied's roundup ties monthly photo updates to more direction requests — reply to new reviews within a day or two, and revisit your categories whenever you add or drop a service. A profile that keeps moving quietly signals to both Google and prospective customers that the business behind it is open, staffed, and paying attention.
That's a foundation, not a finish line. Profile optimization earns you the chance to compete; your website, your reviews, and your reputation decide whether you win. If you'd rather have a team audit your profile against your actual Fort Wayne competitors and build the review and website signals around it, our SEO services are built for exactly this — and you can see how we work with businesses across Fort Wayne and Northeast Indiana.

Frequently Asked Questions
- What is the single most important Google Business Profile ranking factor?
- Across Whitespark's data and its practitioner survey, the primary category is the strongest profile signal you control — and picking the wrong one is the most damaging. Choose the most specific category that accurately describes your core business before optimizing anything else.
- Should I choose a broad or specific primary category?
- Specific, every time. In the 1.8-million-profile study, businesses with specific primary categories appeared in the top 10 about 12.5% of the time versus 9.2% for generic ones. Only pick a category that genuinely fits — accuracy first, specificity second.
- Do additional categories on my Google Business Profile help?
- Yes. The study found well-chosen additional categories correlated with rankings 6 to 17 positions better than profiles with only a primary category. Add every category that legitimately reflects a service you offer, but do not add irrelevant ones to game the system.
- How much does profile completeness affect local rankings?
- Strongly, at least by correlation. Profiles scoring full marks on website, description, hours, photos, and claimed status averaged about 19 positions higher and roughly triple the top-10 presence of empty profiles. Completeness is cheap and largely a one-time task.
- Do reviews still matter for local SEO in 2026?
- Very much — reviews are the second-heaviest signal group after the profile itself, at roughly 20% of local-pack weight. Recency and a steady stream of new reviews matter alongside star rating, and responding to reviews improves both trust and the likelihood customers choose you.
- How is local SEO different for a Fort Wayne small business?
- The signals are the same, but your competitive context is not. In a crowded Fort Wayne category like HVAC or plumbing, most competitors already have complete profiles, so completeness only earns you a seat — recent reviews and a strong website decide the winner. In categories where Allen County or DeKalb County profiles are half-finished, simply claiming the profile and choosing a specific category can outrank neighbors. Because this is correlational data, proximity to the searcher and competitor strength still matter: a fully optimized profile is table stakes for visibility, not a guarantee of first place.
- How often should I update my Google Business Profile?
- Treat it as ongoing, not one-and-done. Keep hours current, add fresh photos regularly, respond to new reviews promptly, and revisit your categories whenever your services change. Google rewards active, accurate profiles, and stale information erodes the trust signals you worked to build.
