What goals do you set in metrics, analytics?

Question

Google Analytics

The site of services, the site has only a phone number and the application form is small. What can be set as goals, indicators? I only have thoughts:
1) Filling out the form
2) Scrolling the page to the form

Answer 1

Single page landing? You can also set the time spent on the page.
But in general, in addition to submitting the form, call tracking should be the main thing for you.

Answer 2

Of course, I would like to see a link to the site, what services you have, and what intermediate target actions can be expected from the user.
In theory, if they got to the site, they choose either a service or a contractor.
At the selection stage, it may matter - portfolio, reviews, video demonstration, guarantees, expert advice.
That is, before the sale there is a stage of gaining the trust of the user. You can set goals for just viewing a portfolio, reviews, writing a question to a specialist for advice.
Maybe signing up for a newsletter, if you do, or getting useful materials on a topic - books or videos.
Something like this.
