The key to reach a nice looking growth rate, 5% to 10% weekly, is to ask people to help you. Go ask the bloggers, youtubers, reporters, and website owners as many as you can.
wow, thanks guys! I sent emails to many YouTubers and let them know my product, and also ask them if they can share us either in their videos or community. For exchange, I will list them as "Partners" on home page or a page you think it has more traffic. In this way, they may say yes in a higher chance.
