Methodology: Routeless audited 35 business websites in San Marcos, TX (2026Q3 benchmark). Homepage signals (CMS, structured data, contact paths, analytics) were collected from each site's live homepage; performance figures are Google PageSpeed Insights mobile lab metrics for the 35 sites that completed a run. Businesses were sampled across industries from public listings and licensing registries; national chains were excluded. Read Google's PageSpeed Insights methodology and download the anonymized San Marcos benchmark summary. We dropped 5 San Marcos sites we couldn't reach, and 35 of the 35 finished a full PageSpeed run.

• 31.4% of the 35 sites have no sitemap we could find, so search engines have to discover their pages by following links.
• Only 11.4% of the sites we tested get enough traffic for Google to publish field speed data, which is measured on visitors' own devices. The rest have lab scores only.

What to look for in a San Marcos web design company.

How we evaluated San Marcos web design agencies.

Scores count only what we could verify in public. If an agency doesn't publish case studies, reviews, pricing, or other proof, it gets no points for that part of the score. That doesn't mean its client work is poor.

• 25Portfolio and demonstrated work
• 20Public case-study evidence
• 15Technical website quality
• 15Verifiable public reputation
• 10Service depth
• 10San Marcos market relevance
• 5Transparency

Choosing which agencies to review is a separate step from ranking them. For that step we look at local relevance, brand searches, how often an agency appears across independent search results, how much public evidence it has, reputation, and a mix of specialties. Every agency that makes the list is scored on the same 100-point Agency Quality rubric, and the 9 ranked agencies are ordered by that total alone. Routeless publishes this research. It's listed as our pick and isn't ranked, so no score is adjusted in its favor. Its remote setup and lack of third-party reviews are scored as found. Technical scores come from each audit, and audits and source facts are dated September 2, 2026.
