Who This Is For

Built for:

  • Developers building affiliate sites
  • Startups shipping MVPs that need to rank

Sample Items (Preview)

Here's a taste of what's in each category.

AI Crawler Management

21 items
- [ ] GPTBot allowed or blocked intentionally
- [ ] PerplexityBot configured for AI search
- [ ] CCBot managed based on training preference
- [ ] ChatGPT-User vs GPTBot distinction
- [ ] AI training vs search bots separated
- [ ] anthropic-ai bot rules configured
- [ ] Google-Extended for Gemini training
...

Why it matters: AI search is growing fast. If you're not configuring these crawlers per Google's robots.txt spec, you're either invisible to AI search or training models for free.

Core Web Vitals

16 items
- [ ] LCP under 2.5s on mobile
- [ ] CLS under 0.1 (explicit dimensions)
- [ ] INP under 200ms (interaction delay)
- [ ] Hero image uses fetchpriority="high"
- [ ] Critical CSS inlined or preloaded
- [ ] Third-party scripts deferred
- [ ] Font display: swap configured
...

Why it matters:Core Web Vitals are a ranking factor. More importantly, slow sites lose visitors before they convert.

Answer Engine Optimization

23 items
- [ ] TL;DR or "Quick Answer" at top
- [ ] Definition paragraphs use "X is..."
- [ ] Lists and tables for scannable data
- [ ] Statistics as quotable snippets
- [ ] FAQ section with clear Q&A structure
- [ ] "How to" steps numbered explicitly
- [ ] Brand name for attribution
...

Why it matters: When ChatGPT or Perplexity answers a question, they cite sources. Google's AI Overviews work the same way. These optimizations increase your chances of being that source.

Starter Kit FAQ

Most checklists were written 2020-2023 and don't address AI search. This checklist includes 100+ items specifically for AI crawlers, citation optimization, and answer engine visibility — plus robots.txt templates for 15+ AI bots.

AI crawlers read your HTML. If your content renders client-side only (CSR), it literally doesn't exist to ChatGPT, Perplexity, or Google. Google's own JavaScript SEO documentation confirms that SSR for money pages is non-negotiable in 2026.

It depends. The checklist includes 3 strategies: (1) Citation-focused: allow AI search, block training (2) Full openness: maximum visibility (3) Restrictive: protect premium content. Most sites should start with citation-focused. Google's crawler documentation explains how Google-Extended differs from Googlebot.

When ChatGPT answers a question, users may never visit any website. Google's AI Overviews work the same way. Zero-click optimization ensures your brand still gets mentioned. The checklist covers citation-friendly formatting and brand mention placement.

Basic familiarity with HTML, robots.txt, and Git helps. The checklist works in any text editor, and the robots.txt template is copy-paste ready. For SSR and Schema.org, you'll need developer skills.

Quarterly, or after major AI search platform updates. The AI search landscape changes fast — last update was February 2026.
