When should a site use Google Analytics?

[alakazam]

Some webmasters use Google Analytics from the first day they launch the website, while others prefer to wait for a few weeks or even months, to get the site some exposure, to allow the crawlers to discover its content, before using Analytics...

What do you think? Which is the best time to start using Google Analytics on your site? From the beginning, or later on after the site grows a bit...?

Its best to apply it from the first day who doesn't want to see the change from its base.

In my opinion, the true track of any site can only be done correctly if it is analyzed from the very first day.

Different websites will have different actions they most want visitors to take. You can set up conversion tracking in Google Analytics for your website based on the actions you most want visitors to take, such as filling out a form, signing up for your email list, or making a purchase.
