Common errors specific to SaaS B2B

  • Treating GEO as “more SEO”. Different ranking signals, different content formats (comparison/listicle), different update cadence.
  • No founder/exec presence on Reddit, X, LinkedIn long-form. Personal brand cited heavily for thought leadership prompts (“who are the experts on X”).
  • Pricing page hidden behind “contact sales”. AI engines can’t recommend you if pricing isn’t public + parseable.
  • Marketing site walled off from indexing for sales reasons. Robots.txt over-restrictions = invisible to AI crawlers (GPTBot, PerplexityBot, ClaudeBot).
  • Skipping G2/Capterra because of bias concerns. Buyers + AI engines treat these as authoritative. Absence = penalty.

Setup: $8-25k. Monthly tracking + content updates: $2-6k. ROI break-even typically 60-90 days post-setup at mid-market.
