The HVAC company hiding in the wrong aisle

The HVAC company hiding in the wrong aisle

Meet an HVAC outfit outside Phoenix. Twelve years in business, solid reviews, invisible for "AC repair" — the one phrase that pays the bills in a desert.

We opened their profile and found the culprit in ten seconds. Primary category: Contractor. Generic. Lifeless. The companies above them all ran HVAC contractor or Air conditioning repair service as primary.

Google's primary category is a heavyweight ranking factor, and theirs pointed at the wrong shelf entirely.

We switched primary to Air conditioning repair service, added Furnace repair service and three more secondaries, and rewrote nothing else.

Nine days later the AC repair ranking jumped from off-the-map to position 4. By week three, position 2 in their core zip codes.

No new content. No links. One dropdown.

Calls climbed 38% over the next month — almost all of them for the exact service they'd been hidden from.

The lesson: your primary category tells Google which race you're even running, and the most expensive SEO mistake is competing in the wrong one.
