A couple of months ago I created my own site for the sale of building materials. All this time, with the help of my friends, I tried to promote it in the search engine. But it has not been a good success. The site is stuck on the fifth page and is not moving forward. Sales are almost at a standstill. This is a terrible situation for me. As an option, I also want to find a popular influencer. What can you advise me on this matter?
