AI Websites Beyond the Basics: Custom Domains, DNS, Email, Search Console, GA, GTM & SEO

AI can stand up a polished site in an afternoon. Production is a different sport. Custom domain, DNS, branded email, analytics, search visibility, monitoring - none of that ships itself. Skipping it is why so many AI sites look great and perform like ghosts.

Buy the domain in the client's own account - never the agency's. Use a registrar with proper DNS controls (Cloudflare, Porkbun, hover) rather than a tied-in hosting bundle. Lock the domain, turn on auto-renew, and add the client's billing card directly.

Ownership is the foundation of every other decision on this list. If the client doesn't own the domain, they don't really own the site.

Set the A / AAAA / CNAME records to the host, add a CAA record to lock down which CAs can issue certificates, and use TTLs you can actually live with - low while you're testing, longer once stable. Document every record with a purpose comment.

Reserve www and root as a matched pair, force one canonical version with a 301 at the edge, and confirm HTTPS is live on both before you announce the launch.

Google Workspace or Microsoft 365 for the inbox. Then the three records that decide whether your email lands in inbox or spam: SPF (authorise senders), DKIM (sign messages) and DMARC (tell receivers what to do with failures). Start DMARC on p=none, monitor reports, tighten to quarantine, then reject.

Add a sensible MX configuration, an autodiscover CNAME if needed, and remove any default mail records the host added during setup. Email reputation is built slowly and burned in a single misconfiguration.

Verify both the domain property (DNS TXT) and the URL prefix property. Submit the sitemap. Set the preferred country if relevant. Watch the Pages report weekly for the first month - this is where indexation problems surface long before anyone notices in traffic.

Install GTM as the only script in the head. Fire GA4 through GTM, not directly. Add consent mode v2 and a cookie banner that actually blocks tags until consent is given - this is not optional in the UK or EU.

Build server-side events for the things that matter: form submits, key clicks, scroll depth on long pages, outbound link clicks. Vanity pageviews are the floor, not the ceiling.

Unique title and meta description per page. One H1 per page. Clean semantic HTML. Image alt text. Open Graph and Twitter card metadata. A real sitemap.xml and robots.txt. Canonical tags. Structured data - Organization, WebSite, Article, FAQPage, Service - wherever they apply.

Performance is part of SEO now: ship modern formats, lazy-load below the fold, keep the LCP element on the critical path. AI-generated sites often pass Lighthouse on day one and regress fast - so monitor it.

Domain in the client's account. DNS documented. Email working with SPF / DKIM / DMARC. Search Console verified, sitemap submitted. GA4 + GTM live with consent. SEO basics in place. Backups configured. A one-page runbook so anyone can pick the site up later.

An AI website that ships without this list is a demo. With it, it's a business asset.
