Domain Name redirection to new Domain Name - VS - Transfering Domaine Name from account 1 to account 2

[Gab-SEO]

Hi there! Thanks for your time

I have a new cutsomer that bought his domain name via WIX and your know... WIX sucks huge time for SEO. Basically, we want to do SEO outside of WIX. But I am not sure HOW I should proceed. I think I have 2 options:

OPTION 1- We transfer the domain name from WIX to a new hoster. But we will lose 7 days during that, lose prospects while the website is in maintenance and we might lose the little bit of ranking we have on the way. BUT! ONCE Everything is done with the transfer, we will be able to operate our SEO campaing with a Domain Name that as 15 domain authority, links, little bit a ranking, etc.

OPTION 2- I just buy a new domain name. I build the new Website on it and then use the SEO juice from the old domain name with redirect to push the new domain name. Like this, I won't lose any opportunities. BUT I will have to restart the SEO as new...

Any tips or ideas for me? Maybe there is an OPTION 3 that I don't know about.
