Launch-day problems are almost always things nobody checked: a broken form, a missing redirect, a page still hidden from search engines. This website launch checklist covers content, SEO, performance and tracking before and after go-live.
Content and links, SEO basics (titles, sitemap, redirects, no leftover “noindex”), mobile performance, working forms, HTTPS and analytics. Broken forms and missing redirects are the most common launch-day problems.
Why do redirects matter when relaunching a site?
Old URLs carry search rankings and bookmarks. Permanent (301) redirects send visitors and search engines to the new pages instead of an error page.
