Creating Your Tag
Your tag is fully customizable. You have the ability to change the number of tags displayed, when they are displayed, and what they say. The most common and easiest dynamic tag to use is one that you can bind to your movement keys (WASD). Meaning that when you move left you could choose to have your tag say "Left" or "Moving Left." or you could bind all of your movement keys to say "Moving." However, there are people who enjoy more elaborate tags that can show their teammates (and enemies) when they are reloading or crouching. The commands for each key are below.

Movement Keys:
bind "w" "+forward;cl_clanid [Group ID Here]";
bind "a" "+moveleft;cl_clanid [Group ID Here]";
bind "d" "+moveright;cl_clanid [Group ID Here]";
bind "s" "+back;cl_clanid [Group ID Here]";

Advanced Movement Keys (DEFUALT KEYS):
Walking - bind "shift" "+speed;cl_clanid [Group ID Here]";
Crouching - bind "ctrl" "+duck;cl_clanid [Group ID Here]";
You can add "_t" (without quotation marks) next to the initial commands to toggle either one of these actions.

Miscellaneous:
Reloading - bind "r" "+reload;cl_clanid [Group ID Here]";
Talking - bind "t" "+voicerecord;cl_clanid [Group ID Here]";
Jumping - bind "space" "+jump;cl_clanid [Group ID Here]"

Now that you have the commands you need the group id's so that CS:GO knows what to display.
You can find these groups through the steam community. For example, the groups Wallhack, Aimlock, Bunnyhop, and Aimbot. You must join these groups for the effect to take place.

bind "w" "+forward;cl_clanid 10088900";
bind "a" "+moveleft;cl_clanid 10088895";
bind "d" "+moveright;cl_clanid 10109772";
bind "s" "+back;cl_clanid 10088936";

To remove your tag Unbind "w" and repeat this for the A,S and D keys as well. Now enter the following commands one at a time.

bind "w" "+forward"
bind "a" "+moveleft"
bind "d" "+moveright"
bind "s" "+back"
