This is just a replica claiming to help you increase traffic to your site. The traffic you create is not real and is just seen on your site to create the impression that you have followers as earlier mentioned. There are no real people on your site but rather software or artificial intelligence. The fake traffic does not convert to real popularity as it is just an impression that can be cleared after some time. The traffic is thus useless to your site.
An e-commerce store: You can buy traffic, but think for a second. Do you really think that they will purchase an item of your’s?. Try to get a targeted country wise or age appropriate set of customer mail list in case of an e-commerce website. In order to find this, you will have to research in the dark web and deep web. It will be expensive as hell if you want to purchase this traffic. Also SEO and re-targeting and re-marketing works well.
