Hello dear @jaytany, welcome to the steemit family. I am pleased to have you here with us.
Tags are normally added to a post whenever it is made. It seems you forgot to add tags to your post but not to worry, you just need to edit your post and add the following are tags
#achievement1 #introduceyourself #newcomers #steemexclusive #yourcountryname, e.g, #nigeria.

After you've added the tags you can notify me so I can verify your post
