How prominence works
Google describes local ranking as a combination of relevance, distance and prominence. Relevance is how well the listing matches the search. Distance is how far the business sits from the person searching. Prominence is how well known the business is — a judgement Google assembles from what the rest of the web says about you, rather than from anything you write on your own listing.
The inputs are the ordinary signals of a business that exists in public: links and articles pointing at your site, directory records, review count and the pattern of reviews over time, mentions in local press and association listings, and Google’s wider view of your web presence. Some of it comes from offline standing that happens to be documented online, which is why long-established businesses often outrank newer ones with better websites.
Why prominence matters
Of the three factors, it is the only one you can genuinely grow. You cannot move the searcher, and local relevance runs out once the listing is accurate and complete — there is nothing left to fix. Prominence has no ceiling.
It is also what widens your radius. A business nobody has heard of appears in the map results only when the searcher is practically outside the door. A well-known one appears across the city. That difference is the entire commercial argument for local link building and steady review collection.
In Kathmandu the effect is easy to see, because trades cluster on the same streets. When a dozen similar businesses sit within a few hundred metres of each other, distance separates almost nobody and relevance is identical once everyone has filled in their listing. Prominence is the only variable left.
Where prominence goes wrong
The reliable way to lose it is to try to buy it. Purchased reviews, bulk directory submissions and paid link networks all leave patterns that are easier to detect than to hide, and the outcome is removed reviews or a flagged profile rather than a ranking gain. Review gating — asking only the customers you expect to be happy — breaches Google’s policy even though it feels harmless.
Two quieter mistakes cost more in practice. The first is assuming prominence transfers between branches: each location earns its own, and a strong head office does not lift a new outlet. The second is measuring it inside the profile alone, when most of what feeds it happens on other people’s websites.
How to build it
Earn mentions where a local person would actually look. A chamber of commerce record, a supplier’s stockist page, coverage of an event you sponsored, an association directory, a university’s partner list — each is modest on its own and they compound. Ask every customer for a review, steadily and as a matter of routine, rather than in occasional bursts that look like a campaign.
Keep your name, address and phone identical everywhere, so that all of this credit attaches to one business rather than to three near-duplicates. Then be patient: prominence is slow, it is cumulative, and it is the part of local SEO that a competitor cannot copy in an afternoon.
