What the site owner should have, instructions so that they don’t get deceived later. To be honest, I’m already tired of talking about this, new people come with questions about why, why and how. I will try to list the points as simply as possible and describe them a little.

1. Site domain , that is, its name by which it accesses the Internet. Only you and no one else, registering is easier than email. If the site is not a few years old, the domain is worth more than its content.

2. Hosting is the place where the resource itself, photos, texts and more are stored. Yes, many people understand little about this, but you can be the most important person on it, and give the webmaster access.

3. Google services, by the way, I recently wrote a note about this . Website analytics, webmaster's office, advertising, tag manager, company profile on the map. Even if you didn’t create it, admin rights can be transferred to you without any problems.

4. Other services for promoting the resource, social networks. Pages in the latter are not difficult to create, but you need to know some nuances, for example, it is better to run Facebook in business on behalf of the page and group.  And of course, they should be created by the owner and not the employee. In other networks, where possible, connect your personal phone.

5. And lastly, YouTube, there are no several administrators. Access can only be given to a manager who can view any information, manage channel access settings, conduct broadcasts, and can also create, edit and delete content. 

Brief, accessible and understandable; more information can be found on the Internet.
