Need help with domain transfer, email verification and SEO on my online store?

Hi,

I originally transferred my domain from godaddy to Shopify but now my email doesn’t work and not sure how to verify it? Under my store detail, the sender email has a yellow mark saying that customers might see no-reply@shopify.com instead. Also, I cannot seem to find my shop online when I google my store name? And I was wondering how does SEO work with Shopify, i read something about connecting google search counsel to provider but then I was unable to add it??
