Why Your Google Maps Rank Changes Depending on Where You Stand in Bangkok
A café owner in Ari checks Google Maps on her phone: her shop is #2 for "coffee near me." Ten minutes later, a friend standing at Asok BTS checks the same phrase and sends a screenshot: she's not in the top 10. Same business, same hour, same city. Nothing is broken — this is how Google Maps ranking actually works.
Google's local pack ranks businesses by distance from the searcher's physical coordinates, plus prominence and relevance. There is no single "Bangkok rank" for your business. There are thousands of them — one for every point on the map. A single citywide rank check is therefore not just imprecise; it is measuring a thing that does not exist.
This post explains grid-based rank tracking — checking your rank at many points across a grid instead of one — why it matters for Bangkok businesses specifically, and how to read a geo-grid report honestly.
Grid rank tracking checks your Google Maps position at many coordinates across an area (for example a 5×5 grid over a 1–3 km radius) instead of one point, because local pack ranking varies heavily with the searcher's location. One business can rank #1 near its doorstep and miss the top 20 two BTS stations away. A geo-grid heatmap shows where you actually win, where you fade, and whether a profile change moved the map. :::
Why One Rank Number Lies
Distance is a first-class ranking factor in the local pack. When someone searches "รับทำ SEO" or "dentist Sukhumvit", Google quietly anchors the results near that searcher. The classic three-pack you see is your rank from YOUR point — a sample of one.
Three ways a single check misleads:
- An agency reports "you rank #3 in Bangkok" — measured from one coordinate, often their own office or a datacenter IP.
- You check from your shop (where you almost always rank well, because you're standing next to it) and conclude SEO is done.
- A prospect two neighborhoods away sees a completely different pack and never finds you.
For a city like Bangkok the effect is amplified: the metro is enormous, BTS corridors create natural commercial clusters (Siam, Asok, Thonglor, Ratchada, Rama 9), and a business that dominates its own soi can be invisible one station away. "Ranking in Bangkok" is not one contest — it is dozens of neighborhood contests stacked on top of each other.
What a Geo-Grid Actually Measures
A grid tracker runs the same search from N points spaced across an area. Each cell records your rank at that point; the result is a heatmap from "dominant" to "invisible". The setup is simple and explicit:
{
"keyword": "รับทำ SEO กรุงเทพ",
"center": "Siam BTS station, Bangkok",
"gridSize": 5,
"radiusKm": 1,
"points": 25,
"competitors": ["top 3 per point"]
}
- Grid size vs radius: a small radius with a dense grid (1 km, 5×5) gives a neighborhood view; a larger radius gives a district view. Bangkok's sprawl usually needs at least district-level grids per location.
- What the colors mean: strong near the pin, fading with distance, is the normal shape for a healthy profile. Weak everywhere — including your own doorstep — signals a profile, category, or consistency problem, not distance.
- Rank at specific landmarks: practical checks like "what do I rank at Siam BTS / Thonglor / Rama 9" translate the grid into places stakeholders actually know. It turns an abstract heatmap into "we own Thonglor, we're invisible past Phrom Phong."
Reading the Heatmap: Patterns and Fixes
| Pattern on the grid | Likely meaning | First move |
|---|---|---|
| Strong core, fades at the edge | Normal distance decay | Grow the core; target adjacent neighborhoods in content |
| Weak even at your own pin | Profile, category, or citation problem | Audit GBP categories, name/address/phone consistency, reviews |
| Strong on one side, weak on the other | A competitor dominates that side | Study that competitor's profile, categories, and review velocity |
| Improves after a campaign, near-side first | Changes are working; prominence spreading outward | Keep going; re-scan the SAME grid to compare |
The comparison rule is the one people break most: grids are only comparable to earlier scans of the same grid — same points, same phrase, same radius. Change any of those and you're comparing two different contests.
What Moves a Grid (and What Doesn't)
Grids are honest because they don't flatter activity that local search doesn't reward:
- Moves grids: Google Business Profile completeness (primary/secondary categories, services, hours), review count and velocity with keywords in review text, photos and posts freshness, consistent name-address-phone across directories, and genuine local prominence (mentions, links from Bangkok-relevant sites).
- Rarely moves grids: generic blog posts aimed at national keywords, social follower counts, paid ads (they run beside the pack, not inside it), and "submission to 500 directories" blasts that Google ignores.
- Negative movers: category mismatches (a café categorized as "restaurant" competing in the wrong pack), keyword-stuffed business names (a policy violation that can suspend the profile), and address changes without cleanup.
Practical Setup for a Bangkok Business
- Pick the money phrase per language. English ("SEO agency Bangkok", "dentist Sukhumvit") and Thai ("รับทำ SEO กรุงเทพ", "หมอฟัน สุขุมวิท"). Search behavior differs between the two audiences; track both, and never assume one represents the other.
- Fix the grid to the service area, not the whole city. A Silom law firm wins Silom and Sathorn; scanning Lat Phrao adds noise, not insight.
- Scan monthly at minimum; weekly during an active campaign. Local packs shift with reviews, competitor activity, and Google updates. Between scans, collect signals, not anxiety.
- Compare like with like: same grid, same keyword, same radius, ideally same time of day. Archive each scan.
- Pair the grid with profile signals — review velocity, photo freshness, Q&A activity — so every rank change has a candidate explanation instead of a shrug.
A minimal manual approximation, if you're not ready for a tracker: check the same phrase from four or five points (walk a few sois, or ask friends in different districts to screenshot their three-pack). It won't give history or precision, but it will prove the variation exists — which is usually enough to retire the "what's my Bangkok rank" question for good.
Frequently Asked Questions
Can I check grid rankings for free?
You can approximate it manually: check the same phrase from different physical points and note the three-pack each time. That demonstrates the variation but doesn't scale past a handful of points or store history. Dedicated grid trackers automate 25–100+ points per scan and keep snapshots so you can compare before/after honestly.
Why does my Thai-keyword rank differ from my English-keyword rank?
Different language means a different competition set and often different searcher locations and intents. Thai and English local results in Bangkok can diverge substantially, so track them as separate grids rather than averaging them into one number.
How often should I re-scan the grid?
Monthly is a sensible baseline; weekly during an active campaign or after significant changes such as a category edit, a review surge, or a relocation. More often than weekly mostly measures noise — the local pack naturally wobbles day to day.
Does a bigger grid help?
Only up to the edge of your realistic service area. Beyond that you're mapping places you deliberately don't compete in, and the average score drags down without telling you anything actionable. A dense small grid beats a sparse huge one every time.
Your Maps rank is not a number. It's a shape — a footprint on the city, strong where your reputation and proximity overlap, thin where they don't. Grid tracking is just the honest way to see that shape. Once you can see it, every SEO decision gets easier: grow the core, patch the weak side, and stop asking for a rank that never existed.
