34 more local businesses scored below the top 15.
How the top three win
What we found
- 37 businesses show up in the map’s top three somewhere in the Charleston area. The map changes block by block, so a business that ranks first in West Ashley can be invisible in Mount Pleasant.
- AI assistants named 11 local businesses between them, and they never all agreed on the same one.
- Some well-reviewed businesses are hard to find. ASP – America's Swimming Pool Company has 231 Google reviews but rarely shows in the map’s top three. Reviews alone don’t win the map.
- The #1 business leads #10 by 31.1 points. For most businesses below the top three, the gap is map coverage and AI recommendations, not the quality of their work.
Who the AI assistants recommend
We asked each assistant, with live web search on: “Who are the best pool service in Charleston, SC?”

Listed as each assistant answered. A business only earns AI points if it is a local business that also appears on Google Maps in the area.
What Charleston customers search

Searches that name Charleston, last 12 months, Google Ads estimates; searches Google groups together are counted once in the total. Most people search “near me” or just the service, which Google doesn’t report by city, so real demand is several times higher.
How the score works
- Map (40): how much of the Charleston area sees the business in Google’s map top three, checked at 49 points across the tri-county for two searches (pool service; pool builder). Businesses with several locations are combined.
- Page one (20): where the business’s own website ranks in Google’s regular results for 3 Charleston searches. Directories like Yelp and Angi earn nothing.
- AI answers (30): 10 points each when ChatGPT, Gemini or Perplexity names the business.
- Reviews (10): total Google reviews on a curve, so the first hundred matter most. Ratings under 4.0 are discounted.
Who’s included: only businesses with an address in Charleston, Berkeley or Dorchester County (or a local service-area listing), in this line of work, with at least 10 Google reviews. For this board we removed 0 listings based outside the area, 3 in a different line of work, and 15 with fewer than 10 reviews, which is usually how lead-generation listings with no real local shop look.
What this score is not: a rating of quality, price or workmanship. It measures visibility only. Search results move daily, so treat this as a snapshot. Nobody paid to be included or to rank higher.
Disclosure: no business in this top 15 is a CORE CONNECT client.
