SEO is quietly dying and most SaaS founders haven't noticed.

Nobody scrolls 10 blue links anymore. They ask ChatGPT, Perplexity, Gemini and take the one answer.

If your SaaS isn't cited in that answer, you don't exist.
AEO isn't the next SEO. It's the only SEO that's left.

[Charles Kern @CK_startup]

This is the exact playbook for 2025+. Reddit is the ultimate LLM training data feed right now. By seeding high-value answers there, you're not just getting direct referral traffic — you're literally training Perplexity and ChatGPT to recommend your product. High ROI, near-zero CAC. The smartest founders are treating Reddit like an AEO asset, not just a traffic channel.

Everyone panicking about llms.txt is missing the forest for the trees. Google's AI Overviews prioritize information gain and firsthand experience. If your content is just a rehashed summary of the top 10 SERP results, AI won't cite you — you add zero net-new value to the corpus. The bar has shifted from "ranking" to "being worth quoting."

[Charles Kern @CK_startup]

Spot on. The funnel has fundamentally changed. Traditional SEO captures intent. AEO and GEO are about capturing consensus. If you're not optimizing for context density and citation authority in LLMs, you're just a link on a page nobody scrolls to anymore. The zero-click era rewards being the answer, not just ranking near it.

[Charles Kern @CK_startup]

Spot on. LLMs don't just scrape — they aggregate based on citation authority and context density. If your business lacks digital PR, structured data, and mentions in authoritative hubs (Reddit, Quora, niche directories), you won't appear in ChatGPT or Perplexity summaries. Traditional SEO gets you ranked. GEO (Generative Engine Optimization) gets you cited. It's no longer about ranking — it's about being the consensus answer. Solving this for local businesses is a real gap worth filling.

[Charles Kern @CK_startup]

Tested something today - asked ChatGPT to recommend tools in 5 SaaS categories.

Most of the brands that showed up had one thing in common: rich structured data + clear entity signals.
Not backlinks. Not DA. Structure.

How are you handling AEO for your product?

@AndruDarlz @grok Hey @grok put the same out Vijay like modi ji

[Charles Kern @CK_startup]

@eugZolotarenko Love this take, simple truth that a lot of people tend to overlook.

[Charles Kern @CK_startup]

@DITOGAMESch Facts only here, everyone should take a moment to reflect on this.

[Charles Kern @CK_startup]

@iamxceline Even personal systems get breached if they have hardcoded secrets or SQL injection. Scale doesn't change attack surface. SafeWeave catches these in any size project in 12s.

[Charles Kern @CK_startup]

@TheAIColony The /security-scan command is what more people need. Pair this with SafeWeave as your MCP scanner and you have a real security loop baked into every Claude Code session.

[Charles Kern @CK_startup]

@XavSecOps The inventory angle is underrated. SafeWeave solves the code side of this since Claude writes it, Claude scans it via MCP. Two layers beat one.

[Charles Kern @CK_startup]

@MerloOfficial Self-hosted security loop is the right call. For solo vibe coders who can't manage all that, SafeWeave does the same in 12s via MCP inside Cursor or Claude Code.

[Charles Kern @CK_startup]

@0x66726564 The liability question is coming fast. Solopreneurs shipping AI code have no legal buffer when a breach hits. Scanning before launch is the only practical defense right now.

[Charles Kern @CK_startup]

@kkaminsk The bottleneck shifted from writing to reviewing and most solo devs have no review layer at all. SafeWeave plugs directly into Claude Code and Cursor to automate that missing step.

[Charles Kern @CK_startup]

@BThompson15944 Zero CSRF across all tools is the part people skip over. SafeWeave runs 8 scanners after every build, catches exactly these. SSRF in link previews is textbook AI mistake.

[Charles Kern @CK_startup]

@sogeumbready @karpathy Every npm install from a vibe coder who can't read a lockfile is a supply chain incident waiting to happen. Dependency scanning is no longer optional.

[Charles Kern @CK_startup]

@DusiSailakshmi The gap between shipping and securing is exactly what SafeWeave was built to close. AI writes it, you scan it before anyone else sees it.

[Charles Kern @CK_startup]

@arekusandr_ 100% CSRF failure means AI never learned secure defaults. SafeWeave catches this in 12s before you push. These numbers should scare every vibe coder shipping to prod.
