I disagree with the previous comment. This is not fashion, this is the reality in which business now operates. Today a huge part of the market has gone into online sales and, accordingly, there is huge competition there. It's no longer enough to just run an ad on a social network and wait. No. users are demanding, and the search engines that cull sites for those users are even more demanding. I do not know if you need SEO promotion or not. This can only be determined by a specialist after the audit. Write to SEO company "To-The-TOP!" for a consultation and clarify all your questions.
