Website SEO Checklist: What to Check Before You Launch (or Relaunch)
A new website can quietly erase years of rankings. Run this list before launch day.
in short
Before launching a site, confirm that every old URL redirects to its new equivalent, each page has a unique title, description, and one H1, the site is allowed to be indexed, pages load fast on mobile, a sitemap is submitted, and analytics and Search Console are connected. Most ranking losses after a relaunch come from missing redirects and accidental noindex tags.
Launch day is the riskiest moment for your search traffic. This list catches the common mistakes.
Redirects and URLs
List every old URL that has traffic or links, and 301 redirect each to the closest new page. Keep URLs short, readable, and consistent.
Indexing
Make sure staging-site noindex tags and robots.txt blocks are removed on the live site. Confirm each key page returns a normal 200 status and has a canonical tag pointing to itself.
Titles, descriptions, and headings
Each page needs a unique title, a clear description, and a single H1 that matches what the page is about.
Speed and mobile
Test on a real phone. Compress images, avoid heavy scripts, and check that tap targets are comfortable and nothing shifts while loading.
Structured data and sitemap
Add schema for your business, services, and FAQs. Generate an XML sitemap and submit it in Google Search Console.
Tracking
Connect analytics and Search Console before launch so you can see the effect immediately and catch problems in days, not months.
Frequently asked questions
It can if URLs change without redirects, if content is removed, or if the site is accidentally blocked from indexing. Done carefully, a redesign usually keeps or improves rankings.
