We know that seeing a self-reference is one of the most common alerts that make us think that our site is mislabeled and although in many cases this is usually the case, we must understand why this happens. 

But how do I know if my site is mislabeled? 

Multi Domains and subdomains.

Your site may be tagged correctly, but if you use multiple domains or multidomains the following may occur.

Example:

If you use a mysite.com domain, GOOGLE ANALYTICS cookies will work fine as long as you browse within the same domain, but if you also use a mysite.com.mx domain and the user moves from one domain to another, the cookies will not be used. will recognize and count the domain jump as a new session.

The session has expired.

Sessions in Google Analytics have a duration of 30 minutes. If the user was inactive on a single page of the site for more than this time and later returns and browses the site again, the session will start again taking the session as a reference source. your own site.

Remember that it is not unusual to see a small percentage of self-referral traffic in your GOOGLE ANALYTICS report, as long as it does not exceed 5% of the total traffic, this way you can be sure that something is not wrong with your site.
