Yes, and the order matters more than many people realise. If the target page cannot be crawled or indexed, a referring page can still send some referral traffic, but it cannot pass the full ranking benefit to a page that search engines cannot rank. I would check, in this order: first, the status code and whether the page is reachable without a long redirect chain; second, the canonical tag, to make sure it points to the intended URL and not to a different version; third, robots and noindex settings, including any inherited settings from a template or plugin; and fourth, whether the page is actually indexed, rather than only submitted, using Search Console's inspection tool.
One extra check that is easy to miss is internal linking. A page that is indexed but buried several clicks from the home page, or only reached through a search filter, will still be weaker than a page that is well connected. Fixing those four checks first usually makes any later work on the page much easier to measure, because you can tell whether a change in traffic came from the page itself rather than from a technical fault that was already there.
