The <title> tag is the most prominent element in search result listings and browser tabs—it directly influences click-through rates and is a confirmed Google ranking signal.
Check the <head> section for a <title> tag. Verify it is unique (not duplicated on other pages), between 10 and 60 characters, and contains the page's primary keyword.
Add or update the <title> tag in <head>. Write a descriptive title of 50–60 characters that includes the primary keyword near the start and is unique across the site. Do not stuff keywords.
The <title> tag appears as the clickable headline in search results and browser tabs. It is a primary on-page SEO factor—Google uses it to understand what the page is about and displays it to users deciding whether to click.
