Technical SEO at launch is about making the intended pages reachable, indexable, canonical and fast enough to use. A new website should not go live with accidental noindex rules, broken redirects or duplicate URL versions that send search engines mixed signals.
1. Check crawlability and indexing
Check that important URLs are reachable without accidental robots blocks, login walls or broken internal paths. Separate pages you intentionally exclude from pages that should be discoverable.
2. Create clean URLs and sitemaps
Keep the sitemap limited to canonical URLs you actually want indexed, return a successful status code, and make sure it updates when important content changes.
3. Improve mobile speed
Test the real interaction on a phone-sized screen. Navigation, forms, text size, tap targets and layout stability matter more than simply passing a responsive breakpoint.
4. Monitor Search Console
Confirm the correct property is verified, check indexing and sitemap reports, and use URL Inspection for important pages instead of assuming Google sees the same page you do.
Pre-launch checks that deserve manual verification
Inspect robots.txt and page-level robots directives, confirm the preferred HTTPS and hostname version, test canonical tags, and make sure XML sitemaps contain only canonical indexable URLs. Redirect old or temporary URLs with appropriate 301 redirects. Check important pages for 200 responses, broken internal links, mobile layout, structured data where relevant, and Core Web Vitals issues caused by oversized images or heavy scripts. After launch, verify the property in Google Search Console and inspect a sample of key URLs.
A simple launch test sequence
Open the homepage, a category, an article and a policy page in an incognito browser. Check source or an SEO inspector for canonical and robots tags, follow the primary navigation, test mobile width, then request indexing or inspect those URLs in Search Console. The goal is to find systemic mistakes before they affect hundreds of pages.
Practical example
Imagine a new WordPress site moving from staging to production. Before launch, check one post, one category and one policy page for a 200 response, indexable robots directive and self-referencing canonical. Confirm the XML sitemap lists the production HTTPS URLs, then test a deliberate old URL to make sure it redirects once to the correct destination. Finally, inspect the same sample URLs in Search Console after launch rather than assuming the deployment worked.
Verify crawl, index and canonical signals before launch
Technical SEO for a new site starts with making important URLs reachable and unambiguous. Test a sample of posts, pages, categories and media-related URLs over HTTPS. Confirm that valuable pages return a 200 status, accidental staging rules are removed, and redirects resolve in a single hop. A sitemap is useful only when the URLs inside it are canonical and indexable.
Check robots directives in both HTML and HTTP headers, then inspect canonical tags on representative templates. Make sure HTTP, www/non-www and trailing-slash variants follow one consistent redirect policy. Review the XML sitemap after launch and submit it in Google Search Console. Use URL Inspection for a small sample rather than assuming that a successful deployment automatically means pages are eligible for indexing.
- Keep internal links pointed at the final canonical URL so crawlers do not repeatedly pass through redirects.
- Return a real 404 or 410 for removed content when no relevant replacement exists.
- Test mobile templates, JavaScript-dependent navigation and important forms after cache or optimisation changes.
- Monitor coverage and crawl anomalies after launch because configuration problems may appear only when search engines revisit the site.
Track indexable URL count, Search Console indexing reports, crawl errors and organic visibility together. A perfect audit score is not the goal; predictable crawling and correct indexing of useful pages are.

Frequently asked questions
Should every page be in the XML sitemap?
No. Include canonical pages you actually want search engines to discover and index; utility or duplicate URLs usually do not belong there.
Is a high performance score required to rank?
No. Performance matters for users and can affect search, but a laboratory score is not a substitute for useful content, crawlability and relevance.
When should noindex be removed?
Only after the production domain, canonical URLs, navigation, core pages and technical checks are ready for search engines.
