Hello there, it seems that you are already selling in US and CA. But, you didn't mention about the products that you selling on Amazon. But let me explain you briefly how I managed to make $37,649 sales for one of my clients.
I followed some of the strategies which helped my client grow on Amazon:
1. Niche Selection- It is very important for you to choose your niche wisely for building brand. I chose a high demand and low competition niche for my client, i.e., Home and Kitchen.
2. Product Research - This phase is all about analyzing current market trends to choose “winning” items.
3. Sourcing - Your product needs to be sourced at targetable rate so that you achieve a minimum of 35% profit margin.
4. Listing Creation & Optimization - Your product listing should contain super relevant KWs. KW stuffing is highly dangerous for listings. I worked and made sure to give high quality images, highly optimized video, A+ content, SEO title, BPs, description and Search terms that helped me rank on 1st page on Amazon with "Best Seller" badge.
5. Ranking - Before your listing gets live, you need to set up your PPC campaigns, MC flows, and other SMM platforms to bring traffic to your listing and get better conversion. In the long run, I have found PPC campaigns the cost effective solution.
Well, this is one of the strategy just to give you an idea.
I’d like to respect your time and keep it short for now.
Just for curiosity, what products are you selling on Amazon?
Cheers!
