Title Tag Meaning in Plain English
A good title identifies the page clearly and distinguishes it from other pages on the same site. Search engines can rewrite the displayed result title when another version appears more useful.
The title tag and H1 can be similar, but they do different jobs. The title describes the document outside the page; the H1 leads the visible content.
Example
<title>Commercial HVAC Repair in Tampa | Example Service</title>This title states the service, location, and brand without turning into a list of loosely related keywords.
Why It Matters
Clear titles help browser users, searchers, and search engines understand the page before opening or evaluating it.
