FORKOFF Perplexity SEO is a citation-engineering service that earns AI and Web3 founders the named source inside the Perplexity Sources panel. Wikipedia presence, niche-pub corpus, original-data drop, Pages canon, Spaces graph, and agent-crawler signal decide which brand sonar, Pro, and Labs cite. Cluster pillar at AEO.
Traditional SEO competes for a Google rank that buyers increasingly skip. Generic GEO agencies ship cross-engine averages that flatten Perplexity's specific retrieval bias toward Wikipedia, niche pubs, original data, and freshness. FORKOFF engineers the authority ladder, the freshness cadence, the Pages canon, and the Spaces graph sonar, Pro, and Labs actually cite. Sister spokes live at ChatGPT SEO and LLM SEO.
Five patterns we see when a brand tries to land inside the Perplexity Sources panel and the work stalls inside the first quarter. Each row is the FORKOFF fix. Read it before you book the audit call.
Perplexity weights freshness more aggressively than ChatGPT, Claude, or Gemini. The Sources panel under each answer surfaces 4 to 8 citations; pages older than 90 days without a freshness signal drop off the panel even when they still rank on Google. The brand becomes a Sources-panel ghost: occasionally cited but rarely positioned above competitor sources.
Quarterly canonical refresh on commercial pages with explicit dateModified schema. Original-data drops every 60 days (Perplexity prioritizes primary sources in Sources panel). Hacker News + Substack syndication of fresh content because Perplexity weights niche-pub freshness heavier than other engines.
Perplexity Spaces is the platform-native curated knowledge base. Competitor brands curate their own Space; users searching the category see competitor-framed Spaces in the suggestion list. Brand answers paraphrase competitor-controlled framing because the Space curation defines the category narrative inside Perplexity. Most agencies do not even know Spaces exist as an SEO surface.
Brand-curated Perplexity Space shipped in week 3 with category-defining sources, founder commentary, and primary-data exhibits. Space optimization for Perplexity discovery (title, description, source curation). Quarterly Space refresh with new sources. Competitor Space monitoring; counter-curate when narrative drifts.
Perplexity Sonar API is the developer-facing retrieval path. Agents, copilots, and integrations querying via Sonar use a different retrieval algorithm than the consumer Perplexity surface; same query can return different sources. Brands optimized for the consumer surface stay invisible to developer-stage buyers because Sonar weights different signals (machine-readable schema, JSON-LD validity, robots.txt agent-friendliness).
Sonar-specific retrieval audit: schema validity for Sonar parsing, robots.txt agent rules tuned for Perplexity user-agents, llms.txt with curated answer units indexed for Sonar. Per-agent retrieval test on the 20 to 40 priority query bench: do Sonar API responses return brand sources at parity with the consumer surface?
Perplexity Pro retrieval surfaces 4 to 5 times more sources per query than free Perplexity, and weights deeper authority signals (academic citations, primary research, longer-form sources). Brands optimized for free-mode citation never compound on the high-intent Pro buyers. Pro users include researchers, B2B buyers in evaluation phase, and AI builders running Perplexity-powered workflows.
Pro-mode bench locked separately: 20 to 40 priority queries scanned in Pro mode every Monday, citation depth and source authority logged. Original-data feeds tuned for Pro retrieval (longer methodology sections, academic-grade citations, peer-citable methodology). Authority-graph signals: founder citations on academic pubs, dataset cross-links to arxiv.
Perplexity Discover is the platform content feed. Brand articles that earn Discover placement get organic distribution beyond direct search. Most agencies treat Perplexity as search-only and ignore Discover entirely. Discover-eligible content has different signals: trend-relevance, original commentary on category news, founder-byline credibility, social co-signal from Perplexity power users.
Discover-eligible content cadence: 2 to 4 founder-byline pieces per quarter on category trends, original commentary, primary research summaries. Format tuned for Discover (clear thesis, primary-source citations, founder voice). Track Discover impressions and click-through separately from Sources-panel citations. Compounds organic Perplexity distribution beyond search.
The FORKOFF Perplexity SEO retainer runs on a single 90-day operating system. Sources-panel baseline captured in the first two weeks across sonar default, Pro, and Labs. Wikipedia, niche-pub, original-data, and Pages plays shipped by week six. Weekly Monday citation receipt in the founder inbox every Tuesday from week four.
4-mode Perplexity baseline locked: Sources, Spaces, Sonar, Pro.
Brand Space live, Sonar API tuned, Pro-mode authority seeded.
Founder-byline Discover-eligible content shipping every quarter.
Weekly 4-mode Perplexity receipt with per-surface delta math.
A citation is only counted when four signals hold every week. Sources-panel inclusion, freshness validity, authority of the host domain, and a receipt logged across all three Perplexity surfaces. Vanity owned-blog mentions without Sources-panel inclusion never land on the ledger.
01 SOURCES PANEL
Brand position in Perplexity Sources panel above competitor citations.
Sources panel under each Perplexity answer surfaces 4 to 8 citations. Position in the panel determines authority signal. Pages with explicit dateModified schema, primary-source data, and Hacker News + Substack syndication hold above competitor citations on freshness-weighted queries.
rule · Brand position in Perplexity Sources panel above competitor citations.
Brand Space shipped with category-defining sources, founder commentary, quarterly refresh. Spaces optimization for Perplexity discovery: title, description, source curation. Competitor Space monitoring; counter-curate when narrative drifts. Most agencies ignore Spaces entirely.
rule · Brand-curated Perplexity Space ranked in category suggestions.
Sonar API uses different retrieval algorithm than consumer Perplexity. Schema validity, robots.txt agent rules, llms.txt curated for Sonar parsing. Pro mode surfaces 4 to 5x more sources per query and weights deeper authority: arxiv cross-links, academic citations, longer-form primary research.
rule · Sonar API parity vs consumer surface, Pro-mode authority signals seeded.
Discover-eligible cadence: 2 to 4 founder-byline pieces per quarter on category trends, original commentary, primary research summaries. Format tuned for Discover: clear thesis, primary-source citations, founder voice. Discover impressions and click-through tracked separately from Sources-panel citations.
