Does this change rankings?

No. The inspector reports which tags are present and which usual ranges they fall in. It does not predict rankings or citations.

Which Open Graph tags does a preview need?

og:title, og:description, og:image, and og:url. og:type tells the platform what the object is. Without og:image, most apps grab a random picture or show no image.

What is a useful twitter:card?

summary_large_image when the page has a large preview, and summary when it does not. X still reads the Open Graph tags when the Twitter tags are missing.

Why list JSON-LD types?

A JSON-LD block names the kind of page, such as Article or FAQPage. The inspector lists the types it found and does not judge the copy.

Does it run JavaScript?

No. It reads the server HTML, which is also what most crawlers see. Client-rendered meta tags will not show.

No. The page is fetched to build the checklist and then discarded.
