SEO considerations for my app (Upload HTML Static Pages?)

Hi there,
So I am a relatively new Bubble User. I am finishing my website here:

I am a SEO consultant and the traffic of my actual website comes mainly from Search Engines so I am really afraid of the migration SEO-wise.

My main concerns and questions:

  • I am thinking of generating my own sitemap instead of native Bubble Sitemap because I see it doesn’t render so well, anyone who has done this? (thought doing it with Screaming Frog)
  • In order to rank landing pages, I’ve seen the solution of webflow, but I am not really convinced. Does someone has just generated static HTML landing pages for content and upload to Bubble?
  • It there a guide for tool?

Many thanks!
