I have a client that set a change of address in Google Search Console where they informed Google that their preferred domain was a subdomain, and now they want Google to also consider their base domain (without the change of address). How do I get the change of address in Google search console removed?

I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

I'm working with a client who is redesigning their site and the new design is very image heavy. Does anyone have any recommendations on the minimum amount of text the homepage should have so that it will rank (or at least not be penalized)? It's a site created by a known brand, but the site itself and URL are relatively new. Katherine
