What a website health check should tell you
A useful health check doesn't just give you a number. It tells you which problems are actually hurting visitors or search rankings, how serious each one is, and what to do first.
LaunchSafer runs over 70 independent checks on up to 10 important pages, weights each by severity, and combines them into category scores and an overall grade. Checks that couldn't run are left out of the score instead of counted as failures.
How the grade is calculated
Passed checks earn full credit, warnings half, and problems none. Categories are weighted (SEO and performance count most) and any critical problem, such as an expired certificate or a site blocked from search engines, caps the overall grade at 49.
Because the grade is rule-based, rescanning the same site gives the same result, apart from small run-to-run variation in lab performance measurements.
Frequently asked questions
Is the website health check free?
Yes. The scan, grade and every finding are free in your browser. Optional extras are a downloadable PDF ($1.99) and AI fix prompts ($1.99), or both for $2.99.
How long does a health check take?
Usually 30–90 seconds. Google Lighthouse performance testing is the slowest part.
Is this the same as a website grader?
Yes. The overall health score is a 0–100 grade, with separate grades for each category so you can see where points are lost.
