Should I run ads now ? which platform and age range is best for my niche?

WEBSITE LINK - https://christxmasly.com/

So after getting some visitors but no sales,I did implement suggestions I got from all shopify users who replied to my previous question and I really appreciate Suggestions I get from here.

Now I think I should run some ads to drive traffic to my store and get some sales but before I do that i want to make sure that everything is alright on the website and need some suggestions on getting HIGHEST SALES AS POSSIBLE because I do not have enough time to take continuous order for christmas in order to deliver them on time (in 20 days).

Need some suggestions and review on website and the best way to run Ads which can actually generate some results.

Thanks for your suggestion
