What we check
Final URL returns 200; 3xx noted, 4xx and 5xx are critical

How it affects your score
This check sits in Search optimisation, which is worth 25% of the overall score. A critical result costs the full weight of the check; a warning costs half. If we can't measure it on your page, we leave it out of the score entirely.
