A title tag is an HTML website element that gives the main title of the page a name. Search engine results pages display the title tag of a site as the headline link users can click making them the very first impression for a user as to whether or not your page is pertinent to them. Title tags are important for search engine optimization, keyword advertising, usability, and social sharing. A title tag should summarize the main point of the article or page in an attention-grabbing and concise way for best SEO practices. Every page on a website should have a unique title tag.
