Missing title tag
A missing <title> leaves search results, browser tabs and bookmarks with no name for the page. One line in <head> fixes it.
What it is
The <title> tag in a page's <head> names the page for browsers, search results and social shares. It's one of the few pieces of a page search engines still treat as an explicit, author-declared signal rather than something inferred from content.
It should be unique per page and, per the usual guidance, somewhere between 10 and 60 characters — short enough that search engines don't truncate it, long enough to actually describe the page.
Why it matters
A missing title tag leaves a browser tab unlabeled, a search result with a search-engine-generated placeholder instead of the page's own words, and a bookmark with no useful name. It's one of the highest-severity findings this scanner reports, because it affects how the page is represented everywhere outside itself, not just on the page.
It's also one of the simplest fixes available: one line in <head>, with no dependency on anything else about the page's structure.
