LLM SEO Services
LLM SEO services optimize a brand to be cited inside answers from large language models — ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. OnyxRank combines answer-first content, schema-rich entity architecture, and disciplined off-site mentions so AI models recognize the brand as the authoritative source on its target topics.
What is LLM SEO?
AI search engines are replacing traditional search for millions of queries every day. ChatGPT, Claude, Perplexity, and Google AI Overviews now synthesize answers from across the web. If your brand is not being cited in these responses, you are invisible to the segment of buyers Gartner forecasts will route 25 percent of search-equivalent queries through AI assistants by 2026. LLM SEO is the discipline of engineering your digital presence so AI models reference your brand as a trusted source.
Reddit Authority Architecture
Reddit is one of the highest weighted sources for AI training data and real time retrieval. We build and manage authentic Reddit presence through strategic thread creation, genuine community engagement, and brand positioning in high visibility subreddits. This is not spam. It is systematic authority building on the platform AI models trust most.
Quora Knowledge Building
Quora answers are indexed by every major search engine and regularly cited by AI models. We create authoritative, detailed answers to high intent questions in your niche, building a persistent knowledge layer that trains AI systems to associate your brand with expertise.
Brand Mention Campaigns
AI models learn from brand co citations across the web. We strategically place your brand alongside recognized authorities and industry leaders across high authority publications, forums, and content platforms. Every mention strengthens the signal that AI models use to determine who to cite.
LLM Visibility Tracking
We run monthly audits querying ChatGPT, Claude, Perplexity, and Gemini with your target keywords and tracking whether your brand appears in the responses. You get a clear visibility score, competitor comparison, and progress tracking over time.

Anonymized Engagement
B2B agency, ChatGPT-driven leads tripled inside one quarter
Client profile, a B2B agency serving series-A through series-C startups, 28-person team.
Problem
Sales reps kept hearing prospects say 'ChatGPT recommended a different agency,' but the brand had no measurable presence inside LLM answers and no way to track citation movement.
Approach
Five-engine baseline (ChatGPT, Claude, Perplexity, Gemini, AI Overviews). Reddit authority threads launched across four target subreddits with a strict two-month no-promotion cadence. Comparison-site listings updated for accuracy and entity consistency. Author entity reinforced through Person schema and named-byline cluster pages.
Outcome
ChatGPT-attributed inbound leads moved from 4 per quarter to 13 per quarter inside 90 days. Perplexity surfaced the brand on 41% of tracked prompts by month four. Internal benchmark across comparable agency engagements.

The five-step engagement model
-
1
Five-engine baseline
We track citations across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews from Day 0. Every monthly report breaks out per-engine win rate; we never report a blended number that hides engine-specific gaps.

2
Reddit authority architecture
We map four to six target subreddits, plan a thread cadence, and have senior strategists do the actual posting under genuine accounts. No spam, no automation, no fake personas. The goal is to become a recognized contributor in the communities that LLMs index most heavily.

Quora knowledge layer
We build a persistent answer base on Quora for high-intent buyer questions. Each answer is engineered for both direct human reading and AI citation, with named author, schema markup on the linked landing page, and supporting context that survives Quora's quality scoring.

Co-citation campaigns
We pitch your brand into comparison roundups, alternative-to lists, and podcast guest spots alongside recognized industry authorities. LLMs learn from co-occurrence; this is the lever that moves citation rate fastest on competitive prompts.

Frequently Asked
Questions buyers ask before they sign
Is Reddit authority work just spam by another name?
No. Our strategists post under real accounts they have built and contributed to for months before any client work touches the platform. We refuse engagements that require fake persona work; Reddit's quality detection is aggressive and any spam-shaped pattern destroys both the account and the brand. Authority is a multi-month investment, not a posting blast.
