WHY? Because it makes your profile much easier to search for.
Ideally, you’re aiming for your URL to look like: www.linkedin.com/in/yournamehere

First, you’ll want to go to your LinkedIn profile. Move your cursor to “Profile” at the top of the homepage, and then select “Edit Profile”.
Next, you’ll see a URL link under your profile photo. When you move your cursor over the link, you can click the little gear-shaped settings icon next to it.
Under the “Your public profile URL” section, click “Edit Icon” next to your URL. This will allow you to enter the customized part of your URL in the text box.
Finally, click Save!
It’s as easy as that. Now, your profile’s URL is customized to your name, making it that much easier for colleagues and potential clients to find you.
