Im looking for an SEO expert for webflow

Hi all, I have recently developed an affiliate based website for a client. He is now looking for an SEO expert. Both he and I are wondering if you have to be an SEO expert with webflow? Or does it matter if you are familiar with webflow or not? I would also ask if anyone can offer me advice on where to find an SEO expert who I can work with on future projects.

Thank you all,

David Roberts.
