I need to promote my website. And so that it is in the top of search engines on the first pages. What are the most effective ways to promote today? I've heard about the backlinks method. How effective is it? How does it work? Please tell me.

When I add an unflitered report on my record page the Filterby is empty.
If you follow https://www.youtube.com/watch?v=sGhOaAO1O-M it should be simple but doesnt seem to work as expected.

The report is on a custom object 
Any ideas?
