Working with ssl checker
Website checks examine different layers: the HTTP response, page source and rendered document may not be identical. Decide whether you need to inspect a URL, validate supplied markup or preview how a browser renders a page.
Common questions
Why can a browser page differ from its source?
JavaScript can add or modify content after the initial HTML arrives. Server responses and client rendering should be examined separately when diagnosing missing content.
Does a passing checker guarantee search rankings?
No. A technical check answers a bounded question, such as whether a tag is present or a URL responds. It does not measure every aspect of usefulness, relevance or search quality.
