South Carolina has a specific and expensive problem for resident-serving businesses: two of its biggest markets generate enormous volumes of search from people who will be gone in a week.
Charleston and the Grand Strand pull tourist traffic that matches service keywords, clicks at the same price as local demand, and converts at close to nothing.
Why it survives in most accounts
Because it is invisible in a summary report. Clicks look fine, cost per click looks fine, and the only symptom is that the booked-job number does not move in proportion to the spend.
You only see it in the search terms report, which is exactly the report nobody reads on a monthly cadence. Filtering is ongoing work — new visitor phrasing appears constantly — not a one-time negative keyword list.
Bridges make radius targeting lie
The other Lowcountry problem is geographic. Charleston is split by rivers, and a job twenty minutes away on a map can be an hour across the Ravenel at five o'clock.
Targeting should follow real drive times at the hours you actually take calls, not a circle. Otherwise you are buying leads in Mount Pleasant for a crew that will not cross the bridge.
The Upstate has repriced
Greenville, Simpsonville, Mauldin and Greer have grown fast enough that the auction has genuinely tightened. Accounts that have not had their structure, negatives, and bids revisited in a couple of years are usually paying a premium for it.
It is no longer the cheap market it was, and the accounts that still assume it is are the ones underperforming.
York County is inside the Charlotte auction
Rock Hill and Fort Mill carry Charlotte-adjacent incomes with lighter local competition — a genuine structural advantage, because Charlotte businesses are too far away to rank in York County's map pack.
But Charlotte's click costs reach across the line. Targeting drawn around your real service area rather than the metro is what keeps that advantage from being eaten by metro bids.
The Grand Strand runs on a calendar
Demand on the coast swings hard between season and winter. A flat annual budget overspends for four months and underspends for eight.
The off-season is not a stop — it is when planned work is sold and when reactivation against your existing customer list is cheapest. The plan changes rather than pausing.
What to do first
Read the search terms report. In a Charleston or Myrtle Beach account, that single hour usually finds more recoverable money than any bidding change would.
