ExpressFlux although a pretty cheap method to "getting traffic" I'm going to explain why it is by far the most expensive method- Their second package for Shopify is $25/month EVEN if i charged 80X that price ($2,000.00/month) It would still cost you less. What I'm getting at is that companies like ExpressFlux won't provide you ANY legit results. Nothing that produces sales, nothing that makes you a return. What you need is to get creative and market your website wherever you believe your target audience is spending time. Not throwing your money at something that will take it and then give you robots and fake numbers.
You can try "WIGZO" for once. I'm advising you on my personal basis. as I'm also confused in my early stage but my friend suggests me this after that I'm fully satisfied with their features which helps me in achieving almost double revenue. you can also try a free demo.
