What parts are links made of? And what are link trackers?

For example: http://www.isachandra.com/2010/07/tofu-omelets/?utm_content=buffer15375&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer

We see a link to the page. However, additional information has been added to this link which should not be shared with third parties.

I recommend removing this additional information to make the link cleaner and therefore prettier/more attractive/safer. People don't trust long links with lots of strange characters.

What is in this link?

1. https:// - this part tells you that this is a web page. Browsers usually add this part automatically and default to http://. Notice the absence of the letter S. Links with http:// are not secure, while https:// is more secure. (The S is not a guarantee of security, but when it is there, it makes you feel safer). You don't have to write this part, but it's good if you do.
2. www. - this part is technically obsolete and well-programmed pages will redirect you to the correct page. However, some pages do not work WITHOUT the www. part! Or they don't work WITH the www. part! The authors of such pages need to give a damn, and remind themselves to pay attention if someone says that the link you shared doesn't work. You don't have to write this part, but it's good if you look at the correct version (i.e. the one the page works with) and use that.
3. isachandra.com - this part is the main domain of the page. It is always necessary to write it.
4. /2010/07/tofu-omlets/ - this part tells you where the specific page you want to reach is. It is also necessary to write.
5. ?utm_content=buffer15375 - this part tells the server that the page has been accessed via "buffer15375". The server captures this information and says "the visitor came from this source". There is no reason for us to include this part when sharing third party links. YOU DON'T NEED TO WRITE THIS PART.
6. &utm_medium=social - AGAIN, NO NEED TO WRITE.
7. &utm_source=facebook.com - I think you get the idea 😉 NO NEED TO WRITE.
8. &utm_campaing=buffer - YOU DON'T NEED TO WRITE EITHER.

What is most important?

isachandra.com/2010/07/tofu-omlets

This is the minimum you need to write to reach the page. That's it! So little! 😉

Some pages are badly programmed, so they need to have a www. part in front. Some also need https:// or http:// (again, depending on which one you are pointing to and which one works).

And how do we know if the page will be available to our followers/customers?
