So the type of website you use does not directly affect ranking, so what's the point in changing provider? This mostly comes down to ease of use, design, and the overall use case.
As you expand or want to have a website update, you may find that your current provider, be it Wix, Squarespace, or IONOS, isn’t giving you the customisability you desire.
Moving to another CMS can allow you to have more flexibility, create pages more quickly, and connect analytics products for clearer data and optimise the websites for more conversions.

conversion rate optimisation aids in designing pages in such a way that that maximises and gets the most signups, sales, or clients as a result.
By looking at analytical data, this can be used to improve on-site elements to satisfy user needs. Simple changes to webpages, such as layouts, call to actions, buy now pay later services, can all be used to increase conversion rate, lowering friction, leading to more sales.
The use of specific language, testimonial integration, and online booking forms can aid in capturing new consumers. Basic CRM systems may be limited in providing the functionality for these, and changing to a new website or provider can help in adding these features.
So overall, the type of website does not matter design-wise as long as there’s relevance and content that is well-formed and interlinked. Although having a sleek design that is easy to navigate, with clear call to actions, and the ability to connect analytics and other third-party applications is important for your needs and overall scaling.
