Title tags or (meta title tags) are a crucial factor in SEO and assisting search engines to understand what your page is about. They provide the first impression that people have on your page. Title tags are used in three key places: search engine results page (SERPs), web browsers, and social networks.
Search Engine Result Page
Your title tag contains (with some exceptions) your display title in the SERP and gives a user their first experience with your website. If your site ranks well, a good title tag can be a make-or-break factor in deciding whether someone clicks on your link.
2. Web Browsers
Your title tag is also shown at the top your web browser and serves as a placeholder, specifically if your user has multiple browsers open. Unique and easily recognizable titles with your keywords near the front help people keep track of your content.
3. Social Networks
Social networks will use title tags to determine what to display when users share that page. Here’s a screenshot from Get The Clicks Facebook, for example:Remember that some social networks such as Facebook and Twitter have their own meta tags. These networks allow you to specify titles that are different from your main title tag. These unique meta tags allow you to optimize for each network and provide longer titles when/where they might be beneficial.
