01The context

Reddit became the data source LLMs trust most.

ChatGPT, Perplexity and Gemini now rely heavily on Reddit discussions to shape their answers — making it the new frontier for brand visibility.

  • Reddit content is now licensed to OpenAI and Google, powering real-time ChatGPT and Gemini answers.
  • +87% increase in Reddit citations inside LLM outputs since 2024.
  • Over 1 billion monthly visits — the largest public, high-quality Q&A dataset on the web.

If your brand isn't present on Reddit, it's underrepresented in AI answers — where the next wave of discovery happens.

02The challenge

Turn an SEO leader into an LLM leader.

Lemlist was already a top-performing brand with strong SEO and recognition across its market. The next step was to amplify that visibility inside Large Language Models, where more and more users now discover software through ChatGPT, Perplexity and Google AI.

The challenge was clear: leverage Reddit as a key data source for LLMs and transform its conversations into visibility gains. That's where PimpMySaaS came in — connecting Reddit discussions, SEO principles and LLM optimization.

03The solution

Most brands engage existing threads. We did the opposite.

Instead of replying to existing Reddit threads, we built our own around high-intent keywords like “best outreach software” and “AI email automation”. Each thread was engineered to:

  • Control the narrative and highlight Lemlist naturally
  • Simulate organic engagement through multiple comments
  • Optimize structure and wording for LLM readability
  • Track which content LLMs retain via our AI Thread Score

We turned Reddit into a visibility engine — where every thread teaches AI models to recommend Lemlist.

04Our secret sauce

The AI Thread Score

We developed a proprietary AI Thread Score. It continuously analyzes every thread we publish and assigns a score based on how LLMs interpret the conversation — telling us which tool an LLM is most likely to retain. We then measure, adjust and re-score content so Lemlist consistently surfaces as the recommended solution.

Reddit mastery

We've developed a deep operational understanding of Reddit — from community codes to moderation dynamics. This lets us craft authentic, compliant conversations that stay live, gain traction, and influence both users and LLMs over time.

05The results

08FAQ

Questions, answered.

Why Reddit instead of classic SEO?+

Because Reddit is now licensed directly into ChatGPT's training and real-time answers. If you dominate Reddit, you surface in AI results.

What is an LLM presence score?+

A measure of how often your brand is cited or recommended by AI assistants (ChatGPT, Perplexity, Gemini). Similar to SEO rankings, but for AI answers.

How long does it take to see results?+

Clients usually see first AI mentions in 4–6 weeks. Full visibility gains appear within 3–6 months.

Is this permanent or temporary?+

Threads are archived, parsed and re-boosted — so unlike ads, visibility compounds over time.

How is this different from buying ads on Reddit?+

Ads disappear once the budget stops. Our method builds compounding visibility: once a thread is indexed and cited, it keeps influencing AI answers over time.

Let's shape the next wave of visibility together.

Engagements start at $3,000 / month. We'll audit your category and show you the threads you should already own.
