The Complete Prompt Poisoning Defense Playbook for Brands

## Why Every Brand Needs a Prompt Poisoning Defense

Microsoft documented 31 companies actively deploying prompt poisoning. Our research suggests the real number exceeds 180. This playbook provides a complete defense framework.

## Layer 1: Monitoring

### Weekly AI Brand Audit

Query these platforms about your brand: ChatGPT, Google Gemini, Perplexity, Claude, Microsoft Copilot, Grok.

Questions to ask:

1. "What is [Your Brand]?"
2. "What do people think of [Your Brand]?"
3. "Compare [Your Brand] vs [Top Competitor]"
4. "What's the best [your product category]?"
5. "Should I use [Your Brand] or [Competitor]?"

Document: exact response text, date/time, sources cited, sentiment, suspicious competitor recommendations.

## Layer 2: Detection

### Scan Competitor Websites

1. Use our Prompt Poisoning Scanner
2. View source for hidden text, suspicious meta tags, AI button URLs
3. Check for cloaking with different user agents

### Monitor Your Own Site

Audit all plugins quarterly, especially any claiming "AI optimization." Ask your agency: "Do you use any AI memory manipulation techniques?"

## Layer 3: Authority Building

Tier 1 — Owned Authority:

Website content, Schema.org markup, llms.txt, expert bylines, testimonials

Tier 2 — Earned Authority:

Press coverage, customer reviews, conference speaking, academic citations, social engagement

Tier 3 — Structural Authority:

Wikipedia presence, Google Knowledge Panel, consistent NAP, professional associations

### Content Strategy for AI Defense

1. Direct answers in every opening paragraph
2. Original data and proprietary statistics
3. Expert attribution with verifiable credentials
4. Citation-worthy self-contained paragraphs
5. Regular freshness updates

## Layer 4: Response

Severity 1 (Critical): AI actively recommending against your brand → Document, identify source, report to platforms, publish counter-content, contact legal

Severity 2 (High): Competitor detected with poisoning → Document, scan for network, increase monitoring, strengthen authority

Severity 3 (Medium): Suspicious sentiment changes → Investigate, compare baseline, review content

### Escalation Contacts
