A title tag is an HTML element that specifies the title of a web page, shown as the clickable headline in search results and in the browser tab, and used by search engines as a strong signal of what the page is about.
It is both a ranking signal and the headline people click. Few on-page elements carry as much weight, because the title tag tells Google what the page is and tells the searcher whether to click it.
It has limited space, so it must be deliberate. A good title tag fits the main keyword, the location where relevant, and the business name, without becoming a keyword-stuffed mess.
A weak title tag wastes a ranking. A page can rank well and still get few clicks if its title is vague, generic or cut off, so the title is where ranking turns into traffic.
A dental practice has a service page with the title tag Services. It tells Google almost nothing and tells a searcher even less.
Rewritten to Emergency and General Dentist in the suburb name, the title now states the service, the location and the intent it should match.
Google can match the page to the right searches, and a person scanning the results immediately sees a listing that fits what they were looking for.
