Competitor Review Audit: A 20-Minute Google Maps Method

A free 20-minute competitor review audit of the businesses above you on Google Maps: what to count, what Google ranks, and what a gap means.

You are comparing yourself to the wrong number

A competitor review audit is the missing step. Most owners check their own rating and stop. A 4.7 feels fine. Then a customer searches "plumber near me", sees you sitting fourth in the map results, and the businesses above you have three times your review count.

Your own rating tells you almost nothing without a comparison. Reviews are judged against the other listings on the screen, by customers and, in part, by Google's ranking. The useful question is not "is my rating good?" but "how far am I from the businesses that win the searches I want?"

This guide is a method you can run in about twenty minutes with a browser and a spreadsheet. It costs nothing. It also tells you what the numbers can and cannot prove, because the common mistake is reading a gap as a verdict.

What Google actually says it ranks

Start with the source, so you know which numbers matter. Google's own page says local results are "mainly based on relevance, distance, and popularity" (Tips to improve your local ranking on Google, Google Business Profile Help, accessed October 2026). Google does not publish a changelog for this page, so treat the wording as current as of the access date and nothing more.

Reviews sit under the third factor. The same page says prominence is "based on info like how many websites link to your business and how many reviews you have" and adds that "more reviews and positive ratings can help your business's local ranking."

Two things follow:

• Google names review count and positive ratings. It does not publish a target number, a minimum, or a formula.
• Distance and relevance come first in that list. You cannot audit your way out of being far from the searcher.

So the audit measures one of three inputs. It does not explain the whole ranking.

Whitespark's expert survey, read carefully

Google's page is short. For a ranked view, the best-known source is Whitespark's Local Search Ranking Factors, an annual survey of local SEO practitioners. The 2026 edition, published 6 November 2025, surveyed 47 experts. In its local pack and Maps section, these review factors scored as follows:

These are practitioner opinions, not Google's data. Whitespark's own method is a survey, and the ranks show what experts believe works. They are still useful for deciding what to measure first. Rating, count and recency all rank in the top fifteen, so those are the three columns in your audit.

The 20-minute competitor review audit

You need a private browser window, so personalised results do not skew what you see, and a blank sheet with six columns.

Step 1: Pick the searches that matter (3 minutes)

Write down the two or three phrases a new customer would really type. "Emergency plumber", "wedding photographer", "dentist accepting new patients". Add the area words you serve. Do not use your business name; people who search for you already know you.

Step 2: Capture the top results (5 minutes)

For each phrase, open Google Maps, search it, and record the first five businesses in the list. For each, write down:

1. Business name and its position
2. Star rating as displayed
3. Total review count
4. Date of the most recent review
5. How many of the last ten reviews have an owner reply

Google says the review score is "the average of all ratings published on Google for that place or business" on a one-to-five scale, and a new review "may take up to 2 weeks" to change the score (Understand review scores for local places, accessed October 2026). That second detail matters for your own tracking: a review you earned yesterday may not move your displayed number for days.

Google's page does not say how it rounds the score you see, so do not compute decimals from the count and call it exact.

Step 3: Sort each profile by newest (6 minutes)

Open each competitor's profile, go to Reviews, and sort by "Newest". Two numbers matter here:

• The date of the latest review. A profile with 400 reviews and nothing in the last four months looks different from one with 150 and a review last week.
• The reviews in the last 90 days. Count them by hand for each competitor. It is tedious and it is the single most informative number in the audit.

Why 90 days? Because that is how customers read. BrightLocal's 2026 Local Consumer Review Survey, published 11 February 2026, asked 1,002 US adults through a representative SurveyMonkey panel and found 74% look for reviews from the last three months. It also found 32% look for reviews from the last two weeks, up from 20% in the 2025 edition.

Step 4: Compare to your own numbers (3 minutes)

Add your own row, measured the same way. Then fill in two gaps for each search phrase: your count against the median of the top five, and your last-90-days count against the same median.

Use the median, not the leader. One competitor with 2,000 reviews, built over fifteen years, is an outlier, not a target.

Step 5: Read the pattern (3 minutes)

A short key for what you will probably see:

What the rating gap costs you

Do not skip the rating column. BrightLocal's 2026 data says 68% of respondents will only use a business rated four stars or higher, up from 55% in 2025. Another 31% will only use a business at 4.5 or above, up from 17%, and 10% will only use a five-star business.

Read these as stated preferences from a survey. People say they filter this way. The survey cannot tell you how many actually did on a given afternoon. But the direction is consistent, and it means a profile at 4.3 is failing a filter that a growing share of customers say they apply before they look at anything else.

For the revenue side, the best-known academic evidence is older and narrower, and it deserves its own caveats; see Star Rating and Revenue: What the Research Shows.

What the audit cannot tell you

Four limits, stated plainly, so you do not overread a spreadsheet.

It does not prove cause. The businesses above you may rank there because of distance, category choice, website links or years of history. Review count correlates with all of those. Google says reviews can help ranking; it does not say that matching a competitor's count will move you above them.

It cannot see the reviews that were removed. Google removes content that violates its policy. A competitor's displayed count is what survived. Do not conclude a rival is "faking" because their number is high.

The count includes reviews of every age and quality. A count of 500 might be 450 reviews from before 2022. That is why the 90-day column exists.

Your sample is small. Five businesses for each of three phrases is enough for a decision about your own asking habit. It is not enough to publish a ranking study.

What not to do with the result

The audit will show a gap. The worst use of a gap is closing it fast.

• Do not buy reviews or pay for them. The FTC's Trade Regulation Rule on the Use of Consumer Reviews and Testimonials took effect on 21 October 2024 and is codified at 16 CFR Part 465, with a section covering buying positive or negative reviews (89 FR 68034). Read the rule text for your own case.
• Do not offer discounts or gifts for a review. Google's contributor policy states that "Rating Manipulation includes Incentivized or Biased Reviews, which are not allowed and will be removed from Maps" (Prohibited and restricted content, accessed October 2026).
• Do not post on a competitor's profile. The same policy bars content based on a conflict of interest and names industry competitors as an example.
• Do not ask only the happy customers. Selective asking is the subject of Review Gating, the FTC Rule, and What Is Actually Illegal, and it is a bad idea even where the law is less clear than the headlines claim.

This is general information, not legal advice. Rules vary and change, so check with a lawyer about your own situation.

Turning a gap into a plan

A gap in count and recency has one honest answer: ask more of the customers you already serve, on a schedule you can keep. The mechanism is boring. After a job closes, a visit ends or an order arrives, the customer gets one short message with one link to your Google review page, sent while they still remember the work.

A tool can run that schedule so it does not depend on someone remembering on a busy Friday. ReviewHero, for example, sends review requests by email, in a sequence, to every customer you add, with no screening on who receives one. The point is the rhythm. If the audit shows competitors collecting a few reviews a month and you collect none, the fix is a habit, and a habit needs a trigger.

Customers must be easy to reach, too. See Where to Find Your Google Review Link, and Where to Send It for the link itself, and Writing review-request emails people actually answer for the wording.

What to do next

1. Run the audit this week. Three phrases, five competitors each, six columns. Save the sheet with today's date.
2. Record the 90-day count for each competitor and for yourself. That is the number to beat, and the one that tells you whether your profile looks active.
3. Pick one target, not three. Set a modest goal for new reviews per month based on how many customers you serve, and ask every one of them the same way.
4. Reply to your recent reviews. Whitespark's survey ranks owner responses low as a ranking factor, but customers read them, and a reply costs two minutes. See Review Response Templates That Don't Read Like Templates.
5. Repeat in 90 days. Run the same searches and compare against your first sheet. Watch the 90-day count move, not the headline rating.

FAQ

What is a competitor review audit?

It is a side-by-side count of your Google reviews against the businesses that rank above you for the searches you want. You record rating, total count, date of the newest review and reviews in the last 90 days, then compare your numbers with the median of the top five.

How many reviews do I need to outrank a competitor?

Google does not publish a number. Its ranking page says only that more reviews and positive ratings can help local ranking, alongside relevance and distance. Use the audit to set a realistic monthly target, not a fixed count.

Should I compare myself to the top result or the median?

The median of the top five. One long-established leader with a very large count is an outlier and a poor target.

How often should I repeat the audit?

Every 90 days. That matches how customers read reviews, and it gives new reviews time to show in your displayed score, which Google says can take up to two weeks.

Can I use the results to ask for reviews faster?

You can ask more customers, on a steady schedule. You cannot pay, reward or screen them. Google's contributor policy and the FTC's 2024 rule both target those tactics.
