Hi @Jolou
Welcome to the community. You did not share a link to your store 
But first, word of warning, you will get tons of emails, and 98% will be scam emails. They are either claiming to be from Shopify, that you need some license, some rules or anything else that sounds legit. Just check the sender’s email. If it is @gmail delete and block. You can even make a filter that if the sender has “shopify” in name but it is still “@gmail” just skip and delete. Next, there will be tons of emails from “experts” that find all kinds of issues with your store, performance, Accessability score, SEO, and marketing. Most of those emails are sent in bulk, and those who hook on it profit. Be really careful who do give access to the store. Do not fall for “gurus” that do not even have a website but on Instagram they claim they can get you 40K a week.
I am also for slow and steady, but that also depends on what you sell. Please take some time to search here for " No Sales" topics. You will find that many store owners make a basic store, then pay some ads and expect miracles. But in reality, their stores need a lot of work. There is a lot of good advice that repeats, and there is definitely a lot that you can apply to your store.
Good luck.
