A launch can break things you cannot see. A broken form loses leads. A missing redirect loses visitors from Google. Check this list before any site goes live.
Forms and links
Test each thing a visitor can click or fill in:
- Every form sends to the right inbox
- Forms show a clear message when something is missing
- The thank-you page or email shows up
- Every link on the site opens a real page
- Search and filters return the right results
- Sign-up, log-in and a lost password all work
- Payments go through in test mode
- Each download opens the right file
- Video and sound play on phones and computers
- It all works on a phone
Search engines
Google needs these to find and show your pages:
- Each page has its own title and short description
- Every page has one main heading
- Every image has alt text that says what it shows
- Page addresses are short and easy to read
- You sent your sitemap to Google Search Console
- The robots.txt file lets search engines in
- Old links send people to the new pages (301 redirects)
- Each page names its main address (a canonical tag)
- Structured data passes Google's Rich Results Test
- Links shared on social media show the right title and picture
- A full crawl finds no broken links
Speed
A visitor on a phone should not have to wait. Check these:
- Run each main page through Google PageSpeed Insights
- Fix what it marks as poor
- Images are compressed and sized for the screen
- Images lower on the page load when the visitor scrolls to them
- Code files are as small as they can be
- Pages and files are cached
- Text shows while the fonts load
- The server answers in a fraction of a second
Keep it safe
Protect your site and your visitors:
- Every page uses HTTPS
- Forms check what visitors type
- Uploads take only safe file types and sizes
- Admin logins use a strong password and a second step
- Each page sends the right security headers
- Passwords and keys stay out of the code
- Backups run at set times
- Someone gets an alert when the site goes down
- Forms limit how often one person can send
See what visitors do
Make sure you can measure it:
- You added Google Analytics 4
- Key actions are tracked, like form sends and button clicks
- Goals are set for calls, forms and bookings
- Google Search Console shows the site as yours
- Campaign links use UTM tags
- The cookie banner works, if you use one
- Your own visits are left out of the reports
