How to make heroku site visible in search engine?

Question

Heroku

The site is on Flask. Tried logging in via .html and pasting the code into the main html file. If you yourself try to access these files in the search bar, then the error is 404. The question is, is it even possible for a site on heroku to give the opportunity to be in the search bar?

Answer 1

Everything was solved by itself, it was just necessary to connect Yandex.Metrica for faster indexing. And about the visibility of files, it was necessary to specify a static folder with authorization files in the code
