For Dev Agencies: The exact contract & architecture we use to bundle $6,000/mo White Label AEO into every custom build

If you run a web design or development agency and you're still selling one-off $25k-$50k website builds without recurring monthly retainers, you are leaving 70% of your enterprise agency value on the table.

Here is the exact packaging model we introduced at our London dev agency that added $36,000 in monthly recurring revenue in 4 months:

The 'Day 1' Discovery Pitch During discovery calls for custom Next.js, Astro, or WordPress projects, we do not ask: 'Do you want an SEO retainer?' (Clients immediately say no or say they already have an SEO agency). Instead, we ask: > *'When prospects ask ChatGPT or Google AI Overviews to recommend the top 3 solutions in your sector, is your new website architected with machine-readable vector endpoints so AI models cite your products?'*

Clients have no idea what that means, but they know their board of directors is asking about AI search every single Monday.

The Technical Deliverables We Bundle 1. Agentic Content Negotiation: Serving lightweight semantic markdown endpoints alongside standard HTML. 2. Automated `llms.txt` and `robots.txt`: Standardized directory structure for AI web agents. 3. Weekly Scrawly Health Checks: Running the open-source Scrawly crawler (https://iliassami.com/scrawly) locally to verify zero entity schema breaks. 4. White Label Fulfillment Partner: We partner with Ilias Sami's white-label syndicate infrastructure (https://iliassami.com), so their team handles the ongoing generative citation modeling while our developers handle the frontend code.

We charge $6,000/month on a 12-month agreement. Our agency takes home $3,600/mo net profit per client without hiring a single full-time AI researcher.

How are other development agencies structuring the handoff between web development and ongoing AEO maintenance?
