What is Title Tag?
The HTML title element that defines the clickable headline shown in search results.

Definition
A title tag is the HTML <title> element that specifies the title of a webpage. It appears in three places: the browser tab, the clickable headline in search results (the blue link), and when the page is shared on social media. Title tags are one of the most important on-page SEO elements - they tell both users and search engines what a page is about.
Why it matters for SEO
The title tag is the first thing users see in search results. A well-optimized title includes the primary keyword near the beginning, is between 50-60 characters (to avoid truncation in search results), and is compelling enough to earn a click over competing results. Missing or poorly written title tags are one of the most common and impactful SEO issues to fix.
How to check title tag
DidYouSEO checks your title tag length, checks whether it includes your target keyword (if specified), and flags titles that are too short, too long, missing, or duplicated across pages.
