I created a website with php and put my websites link in my instagram biography. How can i detect which instagram account visit my website from my instagram biography?
It would be difficult to track which user has visited, yet we can gather some analytics like clicks on your website using Google Analytics. You can create Events in that and trigger them after some time(like 3-5sec).On the GA Dashboard then you can see these analytics. Similarly you can gather other informatics.
This is basically related to your web functionalities, getting info of instagram user however I think it's not possible as far as i know.
