First of all, what is the difference between UTM and REF parameters? I see a lot of big websites have 'ref' in their links.
I always visit a certain website (home url) and all the ref parameters get added to the url while it loads.
How is this done?
When I am tagging my url, it's always a bit.ly link - which doesn't look good at all.
It's much more professional and appealing for people to click on a website with my full name rather than some weird shortened url.
