We have successfully achieved #1 spot on Google for our search term and it remains in that spot for over 2 years now. Since the company is growing we need to completel replace the home page to allow for a Country selector. So an entire new home page, with company logo and a country selection, visitor selects USA or CANADA and when Canada is selected it loads the current SEO ranked website. When USA is selected it will load an entirely new website and new domain.
1. How will this effect our SEO position?
2. What is the best method to roll this out without disrupting our current position?
3. Does adding this new home page mean we will have to start over?
4. Will we need to Submit the Site index to Google search console again?
