Great content cannot rank if search engines cannot crawl and understand your site. Technical SEO is the plumbing: boring until it breaks.

Crawlability

Ensure important pages are linked internally, not orphaned behind forms or JavaScript-only navigation without fallbacks. Review robots rules so you are not accidentally blocking key paths.

Indexation

Use Search Console to see what Google indexes. Investigate “Excluded” URLs and fix duplicates, thin pages, or accidental noindex tags.

Canonical URLs

Canonical tags consolidate duplicate or near-duplicate URLs. They matter for trailing slashes, parameters, and separate mobile/desktop variants.

Site Architecture

A shallow, logical hierarchy helps users and bots. Important pages should be reachable within a few clicks from the homepage.

Structured Data

Valid schema can clarify entities (business, services, FAQs). Treat it as supporting evidence—not a magic ranking lever.

Monitoring

Set up recurring checks after major releases. Technical regressions often ship with redesigns and new features.
