Shopify Question

I started my shopify dropshipping store 6 days ago, I purshased a domain (.com). So far I Ended with the theme costumizations, added around 10 products. my niche is not as known as you may think but I only have 1 big competitor who doesn't offer same products as mine.
I have Added some apps for tracking and shipping. Now I will be subscribing to shopify.
I just wanted to know if I have missed something. or if you have any +.
Also, I will go with google adwords for ads because my product can't do well in facebook ads.

Just takes trial and error from here until the first sale. I see nothing about SEO in your post, however. Hopefully you have at least taken care of the basics?

It doesn't matter if you have competitors or not. From my experience, seeing competitors is a big plus because then you know the products in that niche are selling well. Just because they promote the same products doesn't mean you can't make cash promoting the same ones with different targetting. It's better to see what's selling well and recreating that with your own store.. that way you cut out half of the work.

As for apps, I would recommend getting the oberlo and scarcity app. Don't forget to set your shipping weights/prices accordingly and I highly recommend you do a test purchase before running ads.
