Why am i getting website visitors via what i think are scam links

Help!!

I just received a progress report from Google which shows the top referrers for my website and the links look like scam links!

If I follow the links which go through my site they go nowhere as they do not exist on my website however I find this kind of traffic disturbing.

Can and do I need to stop this and how??

Please let me know.

My website link is: https://joyajewellery.com/
