Key points

  • Netlify SEO ensures search engines can properly crawl and index your site by managing redirects, canonical tags, and sitemaps.
  • Core Web Vitals and page speed benefit from Netlify's CDN and built-in asset optimisation features.
  • Duplicate content issues arise if the default Netlify subdomain remains indexable alongside a custom domain.
  • Structured data in JSON-LD helps search engines understand your content and may enable rich results.
  • Regular checks on redirect chains and canonical tags after deployments prevent crawl budget waste.

How it works

Netlify SEO focuses on configuration choices that affect how search engines interact with a site. Because Netlify is a static site host with a global CDN, it can deliver fast response times, which supports Core Web Vitals. However, the platform's default settings can create problems if not adjusted.

To prevent duplicate content, site owners should set the custom domain as the canonical hostname and use 301 redirects from alternative URLs, including the default netlify.app subdomain. Canonical tags on each page further prevent duplicated indexing when the same content is accessible via multiple URLs.

Build and deploy settings allow optimising assets by minifying CSS and JavaScript, compressing images, and generating pretty URLs. Sitemaps should be submitted to Google Search Console, and structured data in JSON-LD can be added. Performance from the CDN helps meet Core Web Vitals thresholds.

After a website redesign, it is critical to review all redirects and canonical tags to maintain SEO integrity.

Common mistakes

  • Leaving the default netlify.app subdomain indexable creates duplicate content and splits ranking signals.
  • Omitting canonical tags on pages reachable via multiple URL variants leads to duplicate content and dilutes link equity.
  • Using redirect chains instead of direct 301 redirects wastes crawl budget and can slow down crawling.
  • Shipping unoptimised CSS, JavaScript, and images harms Core Web Vitals and page speed, affecting user experience and search visibility.
  • Failing to submit a sitemap or update it after changes slows down discovery of new or updated pages.
