The Google Map Pack: Why Three Businesses Win and You Come Fourth

When you run a local search, you see a map at the top of the results with three businesses underneath it. That block is the Google Map Pack. The industry calls it by several other names too: the local pack, the local 3-pack, the Google 3 pack, the snack pack. Google's own documentation calls it local results.

They all describe the same thing, and the thing that matters is this: there are three slots. Being fourth is close to not being there at all — most people never click "more places".

How Google chooses those three

Google names three factors for local results: relevance, distance and prominence.

Relevance

How well your profile matches the search. Category selection carries the most weight here, and it is the field most businesses never touch.

The primary category decides which queries the profile is considered for at all. Changing "contractor" to "roofing contractor" takes two minutes and is often the single biggest available gain. An over-broad category means never being considered in the results of the person searching for exactly what you do.

Secondary categories count too, but differently: add the work you genuinely do, remove the services you "might offer one day". An irrelevant category dilutes the profile's focus.

Distance

How far the searcher is from the business. This is the factor that separates the map pack from everything else in search.

Two people searching the same keyword at the same moment — not in different cities, but at opposite ends of one neighbourhood — see a different three. Google recalculates the result against the searcher's location on every query.

That has a direct consequence: across part of your service area you will never appear. This is not a failing, it is how the system works. The thing to do is accept it and decide which area you intend to be strong in.

Prominence

How well known the business is, online and off. Review count, review rating, links to the website, consistency of directory listings, press mentions.

This factor moves slowest and lasts longest. Where a category change surfaces within days, prominence is measured in months.

Why local pack rankings look different to everyone

This is the most misunderstood part of local SEO, and in practice the most expensive misunderstanding.

You do not have a single map pack ranking. You can be first from your own doorstep and absent two miles north — same query, same minute.

The concrete consequence: a rank check from one location is misleading. It measures one point on the map, not the map. When an agency tells a client "you're third", it usually means "you're third where my computer is sitting".

The same thing happens in the other direction: an owner searches from inside their own shop, comes up first, and assumes everything is fine. Most of their customers are not searching from there.

How to measure it properly

The right method is to split the area into a grid: place points across the territory you actually serve, run the same search from every point, and record your position at each one.

What comes back is a pattern — where you appear, where you disappear, and who outranks you in the places you disappear.

The pattern carries the answer too:

• Behind everywhere means the problem is the profile or the authority behind it. Look at the category and the reviews.
• Disappearing only at the far points is ordinary distance decay. The fix is a coverage decision, not a profile change — perhaps a second location, perhaps a narrower service area.
• Disappearing in one direction means a strong competitor sits that way. The job is to find who, and the measurable difference between you.

Dating the measurement matters as well. An undated measurement becomes misinformation six months later.

What to do, in order, to get into the map pack

The order matters; working on the lower items while the upper ones are broken is wasted effort.

1. Confirm the profile is verified and the category is exact. Don't move past these two. An unverified profile isn't in the race at all.

2. Measure, then change. Take a grid measurement before the change. Without it you will never learn which change did what.

3. Fill in the empty profile fields. Description, service list, attributes, opening hours, photos.

4. Make directory listings consistent. Your name, address and phone written identically everywhere is worth more than being listed in hundreds of directories. Contradiction lowers Google's confidence.

5. Turn review collection into a continuous habit. Forty reviews from three years ago read as a business that stopped. Replying counts too; reply text is indexed.

6. Measure again from the same points four weeks later. Same keyword, same grid.

Without step six, the first five stay a matter of belief.

Change one thing at a time

Change the category and the address in the same week and you cannot separate what did what. Stacking large changes also extends the review period and sometimes triggers a request to verify again.

One change, four weeks, one measurement. It looks slow, but it is the only way to learn anything.

Being honest about it

There is no guaranteed route into the map pack, and nobody can offer one. The distance factor alone means you will never appear across part of your service area.

What you can do is measure which points you appear at and which you don't, then find the reason for the difference. Trying to fix something you have not measured is repair work done in the dark.
