Illustration for the article: Technical SEO checklist for a new website

Good content helps little if search engines cannot reach it. Use this checklist before you launch, and again after major changes.

Make the site crawlable

  • Remove any noindex tag or password protection used on the staging site.
  • Publish a robots.txt that does not block important pages.
  • Submit an XML sitemap in Google Search Console.
  • Use a clean URL structure with readable words, not IDs.

Get the basics of each page right

  • One unique title and meta description per page.
  • One clear H1, followed by logical H2 and H3 headings.
  • Descriptive alt text on meaningful images.
  • A canonical URL on every page to avoid duplicates.

Speed and mobile

Most visitors arrive on phones. Compress images, use modern formats, avoid heavy scripts and check your Core Web Vitals in Search Console. A fast page helps both rankings and conversions.

Structured data

Add schema markup where it applies: Organization on the home page, Article on blog posts, FAQ and Breadcrumb where relevant. Validate it with Google’s Rich Results Test.

Redirects and errors

  • Redirect old URLs to their new equivalents when you replace a site.
  • Use a helpful custom 404 page.
  • Force HTTPS and a single preferred domain (with or without www).

After launch

Connect Google Search Console and Analytics, request indexing for key pages, and review coverage reports weekly for the first month. Rankings take time; consistent useful content and a technically clean site are the foundation.
