But enough about me, the relevant tags you are seeking appear at the bottom of each content section where you enter your expertise here on Clarity. At the bottom of the text editor box you see the option to enter keywords and the automatic predictive tool gives you suggestions which from where to chose. To add more power to your keyword selection make sure that you are also using the keywords you chose in that section also in your text description of your expertise itself. Having the keywords redundant a bit will help you even more.
