Why Technical SEO Matters

Technical SEO is the foundation everything else sits on. The best content and links will not rank if Google cannot crawl your site, your pages load slowly, or your mobile experience is broken. Most local service business sites have 5 to 10 technical issues silently killing their rankings.

"For local service businesses, the technical SEO issues with the biggest ranking impact are LCP (page speed), missing schema markup, and crawl errors. Fixing just those three categories typically produces a 15-25% increase in organic impressions within 60 days."
Dylan Axelson, SEO Director

Frequently Asked Questions

Comprehensive audit once per year, quarterly spot checks on critical items. After any major site change, audit immediately. Read more about audits.

Can I do technical SEO myself?

You can identify issues with free tools. Fixing them often requires a developer for schema, server config, and code optimization.
