Firstly, let’s consider what a Gravatar profile is…
Gravatars are Globally Recognized Avatars. Integrated into WordPress, Gravatars are an avatar or gravatar is an icon, or representation, of a user in a shared virtual reality, such as a forum, chat, website, or any other form of online community in which the user(s) wish to have something to distinguish themselves from other users.
Definition from WordPress.org
Visiting your Gravatar profile, allows other bloggers to see a list of your websites – if you choose to share them.
If you are going to be visiting other blogs, liking or leaving comments, it is very important to add your website(s) to your Gravatar profile so that others can find you. It is very sad when you want to return visits and are unable to do so!
Step 1: Go to your Gravatar profile and sign in using WordPress.
Step 2: Click on My Profile.
Step 3: Click on Websites.
Step 4: Click on Add WordPress.com website or add website if the website is not on WordPress.
That’s it, folks!
