Improving SEO, Getting first sale

[eco12]

I'd be curious about your advice, if anyone's got any, concerning on how to boost my SEO and getting my first sale. I've started to advertise my store on 4 different social media platforms, but no sales yet, I do get some visits tho. I also would like to improve SEO of course, but do not currently have enough budget to afford a Domain. So for now I'd prefer to stick with the myshopify one.

Here's my Website link: ecodifier.myshopify.com

Check the campaign, if it's properly set or not. And check with the pricing format on the website.

What kind of price format? My product pricing? You're saying that I might overprice my products?
