how we're engineering KILLER google ads funnels with fable 5

fable 5 is Anthropic's most capable model ever released to the public.

it's Mythos-class. same underlying architecture as the restricted model that governments use for cybersecurity. $10 per million input tokens, $50 output. 1M context window. 128k max output. and it handles long-horizon reasoning at a level that makes every previous model feel like it was working with half the information.

we've been using it to build google ads funnels for ecom brands, and the output quality is a step change from what sonnet or opus produced. not incrementally better. categorically better.

the funnels it builds hold together structurally. the copy converts. the backend automations flow. and the speed is borderline unfair: what used to take a week of back-and-forth with a copywriter and a developer now happens in a single session.

here's the full workflow.

if you want us to build this entire funnel system for your brand using fable 5, DM me "FABLE" and i'll show you what it looks like for your account.

why fable 5 is different for funnel work

fable 5 excels at long-horizon reasoning. a google ads funnel isn't one page. it's a system of pages, each connected to the next, each doing a specific psychological job at a specific point in the buyer's journey, with backend automations that continue the relationship after the initial touchpoint.

previous models could build individual pages well. fable 5 builds the system. it holds the full funnel map in context and generates each page knowing exactly where it sits in the sequence and what it needs to accomplish before handing the buyer to the next step.

this is the difference between generating a good advertorial and generating an advertorial that feeds into a comparison page that feeds into a PDP that triggers an email sequence that recovers the buyers who didn't convert on the first pass.

the funnel types and when to use each

advertorial funnels: best for supplements, skincare, health products, anything requiring education before purchase. cold TOF traffic from problem-oriented search queries. an editorial-style page that reads like a health magazine article. hook matched to the search query. agitation. mechanism. solution. CTA to the PDP.

comparison pages: best for categories with known alternatives. conquest campaigns bidding on competitor brand names. MOF traffic from "best X" or "X vs Y" queries.

quiz funnels: best for high-consideration purchases where personalisation increases confidence. supplements (routines), skincare (skin type matching), apparel (fit), pet care (breed-specific needs).

listicles: "top 5" and "best of" format. works in any category where the buyer is browsing options. MOF traffic from ranking queries.

application funnels: best for high-ticket products where purchase friction signals value. limited-edition products. premium brands where exclusivity is part of the value proposition.

VSL funnels: best for complex products that need demonstration. fitness equipment, tech gadgets, anything where seeing the product in action is the conversion event.

PDP: best for branded search and shopping traffic only. buyers who already know and trust the brand. never for cold traffic.

the fable 5 funnel engineering skill

what the backend email automations actually do

the backend automation is where the funnel recovers the 70-90% of buyers who engaged with the content but didn't purchase on the first visit.

the 5-email sequence converts at 15-25% of opt-ins in our accounts. most brands running a generic newsletter are seeing 2-5%.

fable 5 vs sonnet 5 for this work

sonnet 5 can generate good individual pages. for a single advertorial or a single comparison page, sonnet 5's output quality is strong and the cost is significantly lower ($2/$10 vs $10/$50).

fable 5 is worth the cost difference when you're building the full system. the moment the task requires holding the entire funnel architecture in context, generating pages that connect to each other, and building backend automations that reference the content on the landing pages, fable 5 produces a coherent system where sonnet 5 produces disconnected pieces that need manual stitching.

the recommendation: use fable 5 for the initial funnel architecture and the first complete generation pass. use sonnet 5 for iterations, A/B variants, and individual page rewrites after the system is built.

if you want us to build your entire google ads funnel system using fable 5, including the advertorials, comparison pages, quiz funnels, email automations, and the full campaign architecture underneath it, DM me "FABLE" and we'll make it happen.

description: uses fable 5's long-horizon reasoning to design and generate a complete google ads funnel system for an ecom brand, including page copy, page flow logic, and backend email automations.
 
instructions:
1. INPUTS REQUIRED:
   - product description and category
   - price point and AOV
   - primary ICP (age, gender, income, pain points, purchase motivations)
   - secondary ICP if applicable
   - the brand's existing traffic sources
   - the brand's main objections heard from buyers
   - the brand's strongest proof points
   - the brand's tone of voice
   - the brand's website URL
 
2. FUNNEL TYPE SELECTION:
   recommend the primary funnel type for TOF cold traffic, the primary funnel type for MOF evaluation traffic, the secondary funnel type to test after the primary, and flag any funnel type that would hurt performance for this product.
 
3. FUNNEL MAP:
   output a text-based funnel map showing: traffic source > ad type > landing page > next conversion step > backend automation for each of TOF, MOF, and BOF. include the keyword clusters that feed each entry point and the email automation trigger points.
 
4. PAGE GENERATION:
   for each page in the funnel: state which stage it serves, state the conversion goal, generate the full page copy at 800-1500 words, include structural notes on headline hierarchy, CTA placement, social proof placement.
 
5. BACKEND EMAIL AUTOMATIONS:
   for each opt-in point, generate a 5-email post-opt-in sequence:
   - email 1 (immediate): delivery of promised resource + one soft sell line
   - email 2 (24h): deepens the mechanism introduced on the landing page
   - email 3 (48h): social proof heavy, specific testimonials with details
   - email 4 (72h): objection handling, addresses top 3 objections
   - email 5 (96h): scarcity or urgency close
   each email: subject line + preview text + body (200-400 words)
 
6. QUALITY CHECK:
   verify that copy on each page connects to the previous and next, no claim contradicts another, proof points are not repeated verbatim, tone is consistent, and conversion goal is clear on each page.
 
context_requirements: fable 5 (claude-fable-5) required for best results. sonnet 5 can generate individual pages but loses coherence across the full system.
