What is a geo-grid and why measure with it?

A geo-grid runs the same search from hundreds of points across a city and records the map-pack position at each one. It shows how much of the city a business actually holds, which one search from the office cannot.

Who did the work on this home services SEO engagement?

Andy Wang, the founder of SERP Masters, ran the engagement himself. There is no account manager layer: the audit, the fixes, the content direction and the monthly report all came from the same person.

Where do the figures on this page come from?

Every figure is read from a 17x17 geo-grid tracker and call tracking and quoted with its window. SERP Masters does not round figures up, restate them as bigger claims or present tool traffic estimates as visits; reported traffic comes from Google Search Console only.

Will my site get the same result?

No one can promise that. Rankings depend on competitors, algorithm updates, link acquisition and crawl timing, so this page describes one engagement and does not predict another. The free audit shows what your site would need before any work is quoted.

What does a home services SEO engagement with SERP Masters include?

The scope follows the home services SEO page: a technical audit first, then the on-page, local or content work the audit calls for, with every account run month to month and reported monthly.

Figures describe one engagement within the window and tool named beside each one. Rankings move with competitors, algorithm updates and crawl timing, so results from one site do not predict results for another, and no ranking outcome can be projected with certainty.

A home services company lives on the map pack and the phone. This page measures both: the pool service case on a 17×17 geo-grid, and the call volume SERP Masters tracks across its local client base.
