I've searched on the internet of the influence and working of using private or incognito modus while browsing. I can't find an answer but as far as I know if someone clicks an affiliate link at my website while using incognito browsing in most ways the tracking will succeed. But when a user comes back at the website after a few days and buys a product the cookies are gone, the website gets the sale but there's no tracking of the lead/sale.
What are the experiences here and am I right that incognito browsing is bad for affiliate marketing?
