The Dirty Secret of "200+ Directory" Services

Most directory submission services brag about submitting to 200+ directories. But Gartner Peer Insights, G2, Capterra, Software Advice, and TrustRadius account for 88% of all review platform citations in AI Overviews.

Meanwhile, Product Hunt, SiteJabber, and PeerSpot are nearly invisible in AI Overviews. And AlternativeTo, SaaSHub, and FinancesOnline? Not cited at all.

The Question Every Marketer Is Asking

"Do backlinks help with LLM visibility?"

Yes — but the mechanism has changed.

📊

Authority Signals

Backlinks from high-DA sites signal trustworthiness to LLMs during RAG retrieval.

🔗

Co-occurrence Patterns

When your brand appears alongside trusted sources, LLMs learn to associate them.

🔍

RAG Retrieval

AI systems pull from indexed sources. Being on cited platforms = getting retrieved.

Research: How Teams Track AI Visibility

Insights from r/AISearchOptimizers on what actually works

⚠️ The Problem

Most companies have zero visibility into what AI says about them. Traditional SEO tools don't work — AI answers are non-deterministic.

Rand Fishkin's SparkToro study: Only 1% repeatability when running the same prompt.

✅ What Serious Teams Do

1.

Define buyer-intent prompts

"best X", "X vs Y", "is X good for ___" — not random queries

2.

Run across multiple models

ChatGPT, Gemini, Perplexity, Copilot — behavior varies by platform

3.

Track deltas over time

Are you recommended or just listed? Which competitors appear? What sources get cited?

📊 Server Logs Matter

"If GPTBot ignores your pricing page, you're not getting cited." Check your server logs for AI crawler activity.

🧩 Data Structure Wins

"The bot recommends whoever is easiest to parse." Clean structured data = more citations. This is why llms.txt matters.

💡 Bottom Line

The real risk isn't that AI replaces SEO tomorrow. It's that competitors quietly gain recommendation share while you're not even measuring it.
