You may read the full article later but first, head over to this page and claim a vanity URL for your Google Profile before someone else snatches your favorite user name. This is available to all Google Accounts that don’t use a Gmail address.
The current Google Profile URLs look something like google.com/profiles/1082338 but you can now replace that cryptic number with your own unique and easy-to-remeber user name as google.com/profiles/amit.labnol – the new URL is not just easy to remember but may also help improve the visibility of your Google profile in search engines.
There’s an important point here – once you’ve selected a unique name for your Google Profile URL, you won’t be able to change it later or delete it so think before deciding a name.
If you use Gmail, your email username will be your new vanity URL though you still need to activate it from your Google Profile settings. If you don’t use Gmail, you can select any available username to be part of your profile URL. If later on you sign up for Gmail, you can choose this username as your Gmail username.
Update: Your old Google Profile URLs will still work as visitors will automatically get redirected to your new vanity URL. However, if you have linked to the old URLs from any of your web pages, make sure you replace those links with the new URLs because Google is currently doing a 302 temporary redirect that passes only human visitors but not any link juice.
