Ever since I switched my dns to cloudflare my seo went down. From page 1 on serp(not in cloudflare) to no result in serp(in cloudflare). So I tried searching about it in google and many people says it also cloudflare affected their seo and removed it. I also switch back my dns and ip and resubmit my sitemap to google. Just waiting for the result. I want some insight about this issue though. Is it because of the dynamic ip of cloudflare?
