Most local business owners think Google Maps ranking is about proximity. The closer you are to the searcher, the higher you rank. That's partially true — but distance is only one of three factors Google weighs.
The other two are relevance and prominence. And prominence is where most businesses are quietly losing ground — often because of something on their website, not their Google Business Profile.
How Google Actually Decides Who Ranks in the Local Pack
According to Google's official Business Profile Help documentation, local rankings are determined by three factors:
- Relevance — How well your business matches the search query
- Distance — How close your business is to the searcher
- Prominence — How well-known and trusted your business is across the web
Google's exact definition of prominence: "Prominence is also based on information that Google has about a business, from across the web, like links, articles, and directories."
That last phrase — "links, articles, and directories" — is the signal most businesses ignore. Prominence isn't just about your Google Business Profile. It's about whether your website has built authority. Your website's inbound links, your structured data, and your review signals all feed into how prominent Google considers your business to be.
The Schema Signal Most Local Businesses Are Missing
Structured data (also called schema markup) is code you add to your website that helps Google understand exactly what your business is, where it is, and what it offers.
According to Google's structured data documentation for LocalBusiness (last updated December 10, 2025), adding LocalBusiness schema to your site makes you eligible for a Knowledge Panel — the prominent info box that appears on the right side of search results for branded queries.
Knowledge Panel eligibility means Google has verified your business data against your website. That verification signal is a direct input into prominence. Businesses with verified, consistent structured data are easier for Google to trust — and businesses Google trusts rank higher.
The required properties for LocalBusiness schema: name, address, telephone, URL. The recommended properties that increase Knowledge Panel eligibility: openingHours, priceRange, geo coordinates, sameAs links to your GBP and social profiles.
SiteGrade checks whether your homepage has LocalBusiness schema. When it's missing, that's a visibility issue — because the schema → Knowledge Panel → prominence loop is one of the most reliable local ranking levers available.

NAP stands for Name, Address, Phone. It sounds simple. It becomes a ranking problem when the NAP on your website doesn't exactly match what's in your Google Business Profile.
Common mismatches:
- Website says "123 Main St" — GBP says "123 Main Street"
- Website says "555-123-4567" — GBP says "(555) 123-4567"
- Website uses an old address that hasn't been updated after a move
- Website has multiple pages with different phone numbers for different departments
Google cross-references your website's contact information against your GBP and against third-party directories (Yelp, BBB, industry databases). When these sources disagree, Google treats your business data as unreliable — which directly suppresses your prominence score.
BrightLocal's Local Search Ranking Factors research consistently places citation and NAP consistency among the top-tier signals for local pack ranking. It's not the only factor, but it's one of the few you can fix entirely on your own in an afternoon.
Why Reviews on Your Website Also Matter
Your Google Business Profile reviews directly affect your prominence score, per Google's own documentation. But your website can amplify this signal through review schema.
When you display customer testimonials on your website — even simple quotes with a star rating — and mark them up with schema, Google can connect those reviews to your business entity. This doesn't guarantee a rich result (Google explicitly notes structured data doesn't guarantee features), but it reinforces the trust signals that feed prominence.
More practically: a website with visible testimonials, a working phone number, a clean NAP, and LocalBusiness schema is doing four things at once to improve your Maps ranking. A site without any of these is doing zero.
What to Fix This Week
In order of impact:
- Add LocalBusiness schema to your homepage. Google's structured data documentation covers the required properties. Most website platforms have a plugin or field for this.
- Audit your NAP consistency. Search your business name on Google and check every result — your website, GBP, Yelp, BBB, Angi, HomeAdvisor. Make sure the name, address, and phone format match exactly.
- Display testimonials with review markup. Even three real customer quotes on your homepage are worth adding.
- Check that your website links back to your GBP. The "sameAs" property in LocalBusiness schema should reference your Google Business Profile URL.
None of this is fast — it takes an afternoon to do properly. But unlike paid ads, it compounds. A site with clean structured data and consistent NAP improves its Maps ranking over weeks and months without ongoing spend.
