It is pretty simple to setup your domain to redirect to your Google+ profile. For example, I have https://techish.net/+ which redirects to my Google+ profile. This is handy instead of having to link to your Google+ profile manually or using a third-party service. Keeps everything in your control. =)
Apache
If you are using Apache, modify your .htaccess
file and include the following lines.
<IfModule mod_rewrite.c> RewriteEngine On Redirect /+ https://plus.google.com/your_google_plus_profile_id/ </IfModule>
Nginx
If you are using Nginx, modify your nginx.conf file and put the following line within your location {}
stanza.
rewrite ^/+ https://plus.google.com/your_google_plus_profile_id/ permanent;
Great idea.
Yes, I was getting tired of looking up my G+ profile ID and wanted to be able to control it myself (redirect) instead of a third party URL forwarder.
