Try it yourself
Google's own Lighthouse SEO check on one page. All four failed.
Which one has to be fixed before the other three matter?
-
This is the one. It means search engines have been asked not to list this page at all. While that is true the page cannot appear in a result, so a better title, a better description and better links change precisely nothing. Fix it first, then the others become worth doing.
-
Worth fixing. It affects how many people click the result — which only matters once the result exists.
-
Worth fixing, for accessibility first and image search second. Neither helps a page that is not in the index.
-
Worth fixing — "click here" tells nobody anything. Still downstream of being indexed.
Pick a line. Every one of them has an answer.
