A title tag is an HTML tag that labels your page for both real people and search engines. In search engine result pages (SERPs), titles appear as the blue text that people press in order to lead to your page. In addition to that, they also appear at the tops of browser tabs. Title tags, for example, may seem insignificant, but play a far more vital role than it looks like. For instance, in a way that the tidal cover of any book grabs your attention, a title tag of the page is the key step which invites people to click on that page’s search engine result pages(SERPs).
