SEO and UTM GOOGLE

Hello everyone.

I have two important questions regarding the creation of my event.

Is the registration landing page SEO friendly on google? and Can I create a SEA campaign easiest 1-2 week before
I have a domain name that will redirect to the registration landing page. If I insert UTMs in my link for tracking, will this tracking be lost when the site changes url?

for example :

domain
www.miaouwouf.com

Landing page
www.zoom.com/miaouwouf-events/registration

I have to create 3 links
www.miaouwouf.com?utm_campaign=&utm_source=press&utm_medium=Display&utm_content=banner

www.miaouwouf.com?utm_campaign=&utm_source=linkedin&utm_medium=Organic&utm_content=post

www.miaouwouf.com?utm_campaign=&utm_source=facebook&utm_medium=QR Code&utm_content=flyer

or do I create 3 bitly links (for example) that redirect to each link with the UTMs that end on the registration page?
