I have a client who currently has a website running on the platform, Weebly. I am working together with them to upgrade their website and add some additional functionality. To do this I need to transfer their website to the Bubble platform.
My concern is that they will lose their ranking on Google if I transfer the domain to Bubble. Right now they come in at the top of a Google search.
How do I go about transferring their website to the Bubble platform without losing their Google Ranking?
Any tips, past experiences, or help would be appreciated, as I am new to the world of SEO.
