Why is direct traffic increasing?
But there are also people who have tracking blocking in their browsers. It seems that it is by default in Mac, so they are not organic.
Also, some sites have a rule on links not to pass on the addressee, which also makes them a direct instead of a referral.
I usually look at what pages they land on: if it’s the main page, it’s most likely branded search or links.
If it’s articles, it’s search, but with anonymization in the browser.
