## 2. How to Allocate a Sub-$100/Month AEO Budget (Observation vs. Remediation)
1. **Fix Physical Bot Ingestion First ($0 to $79–$99/mo):** Paying for a prompt tracker while your Shopify, WordPress, or Next.js site truncates pricing at 25,000 tokens or lacks a root `/llms.txt` only confirms that bots cannot read your site. Start with the **$0 AnswerRail Free Grader** (`npx test-ai-ready <url>`), then activate **AnswerRail Starter ($79/mo annual / $99/mo monthly)** to serve Byte-0 Markdown tables and log real `PerplexityBot` / `OAI-SearchBot` hits across 3 domains.
2. **Layer Low-Cost Prompt Polling Second ($29–$95/mo):** Once your edge rail is active, pair it with **Otterly.AI ($29/mo)** or **Peec AI (€89/mo)** to track synthetic prompt positions without paying $499–$2,500/mo for Profound AI.
