Technical SEO

Technical SEO checklist for developers who ship websites.

Technical SEO is strongest when it is implemented in the codebase, not only described in an audit. Developers can fix crawl signals, rendering, structured data and performance at the source.

Technical SEO and Speed Optimization

Crawl and indexation basics

Every important page should have a clean canonical URL, indexable robots meta tag, unique title, useful meta description and inclusion in the XML sitemap. Low-intent utility pages should usually stay out of the sitemap or use noindex.

Structured data essentials

Service pages should use Service, FAQPage and BreadcrumbList schema when the visible content supports it. Case studies can use CreativeWork and breadcrumbs. Personal brand sites should reinforce the author entity with Person and ProfilePage schema.

Performance and rendering

Check image sizes, font loading, JavaScript weight, layout stability and interaction cost. If a page is primarily content, the main answer should exist in the initial HTML and not depend on client-side JavaScript.

FAQ

What technical SEO fixes can developers implement directly?

Developers can fix metadata, canonical URLs, schema, sitemap generation, robots directives, redirects, rendered HTML, images, scripts and Core Web Vitals issues.

Should every page be in the sitemap?

No. The sitemap should include canonical, indexable URLs that support the site search strategy. Thin, duplicate or low-intent pages should be excluded.
