Launch day goes smoothly when the checking is done beforehand. Work through this list before you point your domain at the new site.
Check the content and function
Test it like a customer would.
- Every page, link and button works
- Contact and quote forms send and you receive them
- The site looks right on a phone and a desktop
- Spelling, phone numbers and prices are correct
Check the technical basics
Confirm the site uses https, each page has a title and description, old addresses redirect to new ones and the sitemap is ready. Make sure search engines are allowed to index it.
Plan the day
Back up the old site, launch at a quiet time, test again right after and keep watch for the first few days. Tell Search Console about the new sitemap.
