I would suggest focusing on the SEO first and then other ways of getting visitors, because it is the most targeted and the best converting kind of traffic you can get nowadays.

You can do that for free and almost effortlessly. You should not copy any video descriptions from other websites, instead, do not post them at all or better write them manually yourself. It can be two or even just one sentence long and it can help you get rankings on the Google.

Instead of just using the numbers, you should make your post links search engine friendly. You can change that by going to Settings and then Permalinks and you would suggest you to choose the URL structure “post name” and it is the one that I am using and most of the websites are using.

I see you are getting views from Reddit but I really doubt it converts into many sales.
