Alternative ways to promote a website. Let's start with the main way to advance, of course this is the unique content of your resource. And of course, links from well-known sites. which is a costly endeavor for many. 

How to make a site index faster has already been said about articles. But when the resource is young, Google won’t pay much attention to you for three months. In addition to the sitemap in Google search console, I recommend adding a link to your RSS feed if you have one. 

Masters talk about white and black promotion, but I advise you not to do black. Once I experimented myself, and my site was banned for a long time. And only after deleting some articles and links was it possible to restore indexing.

When you are offered to advance in social networks, what matters is age and how this or that page or group on Facebook was maintained. And the number of subscribers does not always play a significant role in this. Other social networks, such as Twitter and LinkedIn, generally proxy the link, that is, it is not direct. 

Everyone’s favorite Google, my business now even offers to include links from your social networks in your profile. And I recommend doing everything in ascending order, or rather popularity. By the way, creating a new business profile on the map is becoming increasingly difficult. But for users with a level 8 rating it is easier ;)
