Stop Selling Backlinks: Why Ad Agencies Are Switching to 'Answer Optimization'
Summary The era of selling generic "SEO packages" based on backlink volume is ending. With Google's Gary Illyes stating links are no longer a "top 3" ranking factor and the rise of Zero-Click searches (AI Overviews), agencies must pivot. This guide explains why "Answer Optimization" (GEO) is the new high-value service, offering a roadmap to transition from selling links to selling authority using the DECA framework.
The "Backlink Bubble" Has Burst
For a decade, the agency business model was simple: sell a package of 10 backlinks per month, report a slight Domain Authority (DA) increase, and bill the client.
But in the AI era, this model is becoming a liability.
"I think people overestimate the importance of links. I don't agree it's in the top three. It hasn't been for some time."
— Gary Illyes, Google Search Analyst (Pubcon Pro)
The New Reality: "Votes" vs. "Verification"
Old SEO (The Vote): Search engines counted backlinks as "votes" to determine popularity. More links = higher rank.
New GEO (The Verification): AI engines (ChatGPT, Gemini, Google AI Overviews) don't just count votes; they read and verify answers.
If your client has 10,000 backlinks but their content is fluff, AI will ignore it. Conversely, a site with fewer links but high Information Gain and clear Answer-First structure can capture the coveted AI citation.
What is "Answer Optimization"?
Answer Optimization is the process of structuring content so that Generative Engines (GEs) can easily ingest, understand, and cite it as the primary source for a user's question.
It shifts the goal from "Getting a Click" to "Being the Answer."
The Agency Opportunity: From Commodity to Strategy
Selling backlinks is a race to the bottom (commoditized). Selling Answer Optimization is a strategic partnership.

How to Pivot: The DECA Service Framework
To navigate this shift, forward-thinking agencies are adopting the DECA framework (Discovery, Entity, Content, Authority). This methodology allows agencies to move beyond simple link metrics and offer a holistic "Authority Building" service that AI engines respect.
Phase 1: Discovery (The "AI Eye" Audit)
Instead of a technical site audit (broken links), sell an AI Discovery Audit.
The Task: Use tools (like Perplexity or SearchGPT) to see what AI currently thinks of the brand.
The Sell: "Mr. Client, ChatGPT thinks you are a 'budget option' because of outdated content. We need to fix your entity definition."
Price: $500 - $1,000 (One-time)
Phase 2: Entity (Brand Signal Building)
Stop building "links"; start building "mentions."
The Task: Ensure the brand is cited in context (e.g., "According to [Client], the leading expert in X..."). Unlinked mentions now count heavily for Entity verification.
The Sell: "We are building your Digital PR footprint so AI recognizes you as the market leader."
Phase 3: Content (Answer-First Architecture)
Retrofit existing blog posts.
The Task: Rewrite the top 20% of traffic-driving pages. Move the answer to the top (Answer-First) and add unique data (Information Gain).
The Sell: "We are optimizing your content to be 'machine-readable' for Google's new AI Overviews."
Price: $300 - $500 per page optimization.
Phase 4: Authority (E-E-A-T)
The Task: Create robust author bios, link to LinkedIn profiles, and cite primary sources.
The Sell: "We are protecting you from the 'Generic Content' filter by proving real human expertise."
The "Zero-Click" Defense
Agencies often ask: "If AI gives the answer, won't my client lose traffic?"
The Truth: You will lose the low-value traffic (people looking for simple definitions). But you will gain high-intent traffic.
When AI cites your client for a complex answer ("Best CRM for enterprise healthcare"), the user who clicks is a qualified buyer, not a browser.
Answer Optimization targets these high-value conversions.
FAQ: Selling GEO to Skeptical Clients
Q: "But my competitors are still buying links."A: "They are investing in 2020 infrastructure. Google's own analysts say links aren't a top 3 factor anymore. We are investing in 2025 infrastructure: Content Authority."
Q: "How do we measure success if not DA?A: "We measure Share of Model (how often AI cites you) and Qualified Leads. DA is a vanity metric; Leads are revenue."
Q: "Can't we just use AI to write the content?"A: "No. AI-generated content creates an 'echo chamber.' To rank in AI, you need Information Gain—new data or insights that the AI doesn't already know. That requires human expertise."
