Need help to rephrase this sentence!

Can someone please help me to re-phrase this sentence?

“Points will be assigned based on the numbers of appearances the items listed in the sub-groups appeared in the website.”

I want to say that point will be assigned each time an item in the checklist appeared in the website. For example: if email are listed in website 4 times then 4 points will be assigned.


Is this sentence grammatically correct?
