1. Treat La Mesa as a city inside a deliberate county footprint
Bosseo’s public programmatic SEO page describes two geographic choices: statewide coverage or a tighter set of counties. La Mesa is recorded as a municipality in San Diego County, California. That makes San Diego County the relevant starting point for a county-scope discussion, while the city itself remains a distinct page location. The Census population estimate can help establish that La Mesa is a substantial municipality, but it cannot prove that residents are searching for a particular legal service or that a page will rank. A useful evaluation therefore maps the places your firm actually serves rather than multiplying pages from population alone.
Recommended approach
Ask Bosseo to review La Mesa within a San Diego County footprint and to distinguish La Mesa pages from pages for other county municipalities. Decide whether every included city reflects a service area your firm can responsibly handle. Keep statewide expansion as a separate decision, supported by service capacity and measurement rather than by the city’s population.
