Local SEO ROI: Before and After Your Google Business Profile (GBP)

Return on investment is simple on paper: extra profit minus what you spent, divided by what you spent. The hard part is the word 'extra'. You need to know how much more you earned because of the work, which means knowing what would have happened anyway — the same season last year, the same ads, the same word of mouth.

Local SEO changes where your business appears when someone searches near you: in the map results and local panels, not just the ordinary blue links. So the outcomes that matter first are the actions people take from your profile — calling, asking for directions, tapping through to your website, sending a message, booking. Rankings and impressions are inputs. Jobs, sales and profit are outputs.

Most published case studies report the inputs and then jump to a revenue figure, skipping the middle: how many of those extra calls became paying customers, and what each one was worth. That middle step is where your own numbers matter most, and it is the one you can measure better than any agency can.

Search visibility isn't one thing, and each layer reports in a different place. Mixing them is the most common reason owners can't tell what is working.

To be clear about what the evidence supports: we found no public study that isolates the incremental return of each layer separately. Published results almost always bundle website work, profile work and review work together. The practical consequence is that you should measure each layer on its own dashboard and avoid crediting one layer with results you can't separate.

Google's own Business Profile help describes three factors. Relevance is how well your profile matches what someone is searching for. Distance is how far you are from the searcher. Prominence is how well known your business is, which Google ties to things like links to your website and your review count and ratings. Google also states plainly that there is 'no way to request or pay for a better local ranking.'

That framework tells you what to baseline. You control relevance directly: your categories, description, services and completeness. You influence prominence over time through reviews and the sites that link to you. You cannot change distance — if a competitor is closer to the searcher, the answer is relevance and prominence, not tricks.

Reviews also matter beyond ranking. BrightLocal's Local Consumer Review Survey 2026, which asked 1,002 US adults and was published on February 11, 2026, found that 97% of consumers read reviews for local businesses, and 41% said they always do, up from 29% the year before. A profile that ranks but has a handful of old reviews can lose the customer after the click.

Google's documentation lists the performance metrics available for a verified profile: views on Search and Maps, calls, messages, bookings (when they are made through a booking provider), direction requests and website clicks. You open them from the Performance page of your profile and choose a time period. Performance data is only available once the profile is verified, so verification comes first.

These numbers describe what happened on the profile itself. They will not appear as visits in your website analytics unless someone taps through, which is why 'website clicks' is only the hand-off. What happens after the click has to be measured on your site.

A baseline is just a dated record of where you started. Without it, every later number is a story. Take an hour to write down the following before you edit a single field, because the moment you change your profile you can no longer recover the 'before' picture.

Do the work in order, and change things in batches rather than all at once. If you rewrite your description, swap your categories, add photos and launch a review campaign in the same week, you will never know which change did what.

We checked five published local SEO case studies against their original pages. All five come from the agencies that did the work, so treat them as vendor-reported results rather than independent evidence. Where the page says a revenue figure is an estimate, we say so.

The first is a boutique medical spa in Mississauga, Ontario, written up by Parkyd Digital over six months. The numbers on the page are specific and the starting points are small: profile views rose from 225 to 2,587, calls from 7 to 94, direction requests from 28 to 44, and website visits from the profile from 62 to 159. The agency also reports 109 leads from organic search, which the page says exclude profile interactions, and an estimated $70,000 in additional revenue that it attributes to search-driven traffic as a whole, not to the profile alone — an estimate, not tracked revenue.

Notice how much the percentage depends on the starting number. Going from 7 calls to 94 is a 1,243% increase and a headline-friendly one; going from 28 direction requests to 44 is a 57% increase and gets no headline. Both are real. Only one of them tells you that a small base inflates the percentage.

The second case is an OB-GYN practice written up by DYB Digital. The agency lists appointments for June to October of 2023 and of 2024 and states a total of 277 additional appointments. It reports profile calls up 183.2%, profile views up 47.1%, direction requests up 64.1%, website clicks from the profile up 33.7% and search impressions up 389.96%.

Four details matter, and the first is a good lesson in checking the arithmetic yourself. The five monthly figures on the page add up to 489 appointments in 2023 and 798 in 2024, a gap of 309, but the page states a total of 277. At the page's own $386 per visit, 277 appointments gives the $106,922 headline while 309 would give $119,274. We quote the page's stated total and flag the mismatch rather than choose one.

Second, the revenue figure is an estimate. The headline says 'estimated', one line calls the same number 'tracked', and the working is simply extra appointments multiplied by an assumed average visit cost. Third, the timeline is unclear: the page describes optimization starting around February 2025 while the comparison covers 2023 and 2024, so a reader can't tell exactly what period the work covers. Fourth, the page mentions a 'limited budget' without giving the amount, so the headline ROI of 3,367% can't be verified. A year-over-year comparison does control for season, which a simple before-and-after doesn't, but it still can't show what else changed in a year: staffing, insurance, a competitor closing.

The remaining three show the range of what agencies publish. One reports profile searches, calls and views for a medical spa client but mixes comparison periods. One reports a home services company's monthly leads and revenue without naming the client. One is an owner's own statement in a press release. None of them is wrong to publish; each simply supports a narrower claim than its headline.

Big percentages usually come from one of six things, and each is easy to check once you know to look.

Small starting numbers: a business that received 7 calls a month will show a four-digit percentage from a modest absolute gain. Always ask for the raw counts. Estimated revenue: 'additional revenue' is often appointments multiplied by an average price, not money traced to a profile. Bundled work: most of these engagements also included content, a new website, ad changes or a review campaign, so no single piece can take the credit.

Mixed baselines: one metric compared with last month and another with last year can't be read together. Selection: agencies publish their best results and rarely their ordinary ones, so a collection of case studies shows what is possible, not what is typical. Missing costs: a return needs a cost, and many pages never state one.

None of this means the work doesn't help. It means a case study is a hypothesis to test against your own numbers, which is exactly what a baseline lets you do.

Work from your baseline. Take the extra actions the profile produced over a period, convert them into extra customers using your close rate, multiply by what each customer is worth to you in gross profit, and subtract what you spent. Use profit rather than revenue: a job that brings in $400 but costs you $200 to deliver adds $200, not $400.

The example below uses made-up numbers purely to show the arithmetic. Replace them with yours. If you want to run your own figures, the free ROI calculator and profit margin calculator on this site do the same sums.

One more adjustment matters: if your business is seasonal, compare against the same months last year or against a period when nothing changed, so a busy season doesn't get credited to your profile.

Where the case studies above state a period, it is roughly five to six months. That is a reasonable guide, not a guarantee. A practical rule is to check direction at 90 days and decide at six months, because new reviews, edited content and a revised category setup all take time to be reflected.

At the 90-day checkpoint you are asking only whether your numbers are moving the right way, not whether the work has paid off. Calls trending up with a stable close rate is a good sign. Views up while calls stay flat means people see you but aren't choosing you, which points at your reviews, photos or description rather than your ranking.

People increasingly ask AI assistants for a recommendation instead of scrolling a list. We found no independent study that isolates how much that changes local leads, so treat this layer as a leading indicator, not an ROI line.

Measure it simply: once a month, ask three to five questions your customers would ask, in the assistants they are likely to use, such as the best business of your type near a particular neighborhood. Note whether you are named and which sources are cited. In your website analytics, give visits that come from AI assistants their own line so you can watch it grow or not. Consistent business details across your site and profile can only help the assistants describe you correctly.

A short, boring plan beats an ambitious one you abandon. The point of the first ninety days is to fix the basics, change them in batches, and keep the records that make the comparison possible.
