Lots of variables.
As it is a personal art site branded traffic will depend on how big of a name they have and if people search them out.
If it were me I would do an inventory list of where you’re at. What’s your load time , what is an easy fix on the site to help boost it.
Then I’d look at where you stand , figure out the keywords that you want to have and see how the competition is. Do a list on how they compare to you, links , content , on page SEO etc.
Then I’d see where I have opportunities. What do you rank for already. Can you easily improve? Do any of these kw drive traffic that converts?
