How many redirects are too many?

Aim for one. Every extra hop adds a round trip, and Google stops following after about ten. A chain like http → https → www → final page should be collapsed into a single redirect.

Can robots.txt remove a page from Google?

No. robots.txt stops crawling, not indexing - a blocked page can still appear in results. To remove a page, let it be crawled and add a noindex tag.

Do I need security headers?

Yes for any site with a login or forms. HSTS, a Content Security Policy and X-Content-Type-Options stop common attacks, and they cost nothing to add.

What these website checks are for

The technical basics that decide whether Google can crawl your site and whether browsers trust it: redirects that go straight to the right page, a robots.txt that does not block what you want indexed, a sitemap that lists every page correctly, and the security headers that protect visitors.

These are the checks to run after moving a site, changing hosting or switching to HTTPS - the moments when they most often break without anyone noticing.
