A 'hit' is when someone visits your page and it gets counted (like from '71' to '72' )
Also if you want to make an ID thingie: When submitting a picture, be sure to not click on 'Indyart' and instead click on 'designs' then 'deviant id.' When you are done submitting, you can then go to your settings on your users page and select your id thingie on the deviant id options (the same goes for featured deviantart, just scroll down and select)
I hope this helps, good luck!
