Title tag
The HTML title element that names a page. It is a primary relevance signal and usually the clickable headline in search results.

The title tag is the HTML title element in the head of a page. It serves two jobs: it is one of the strongest on-page relevance signals, telling engines what the page is about, and it is typically what appears as the bold, clickable headline in the search results, which makes it a major driver of click-through.
The craft is to be both relevant and compelling within the space Google will display, roughly 50 to 60 characters before truncation in most desktop results. Lead with the primary topic, make it specific and accurate, and avoid keyword stuffing or boilerplate repetition across pages. A unique, descriptive title per page is the baseline; duplicate titles across a site are a common and costly error because they make pages compete with each other and confuse the engine about each page's focus.
Google frequently rewrites titles in the results when it judges the page's actual content or a heading better matches the query, so the title you write is a strong input, not a guarantee of display. The defense is to make the title genuinely match the page's content and the query intent, which reduces the chance of a rewrite. We check title presence, length, uniqueness, and topic match.
