A title tag is the main text that describes an online document. It is the single most important on-page SEO element (behind overall content) and appears in three key places:
-Browser
-Search result pages
-External websites
The title element of a web page is meant to be an accurate and concise description of a page's content. Creating a descriptive, keyword-laden title tag is important for increasing rankings in search engines.
Words in title tag can generate quick and appreciable differences to your rankings.
