GEO / AEO philosophy

Grizzle’s view is that SaaS brands often lose AI citations because nobody is earning the off-site mentions models trust. On-page content alone is not enough; digital PR and mention generation have to sit in the same roadmap.

Offering

  • Builds SaaS content hubs and on-page SEO while running mention generation and digital PR for off-site authority.
  • Staffs strategy and execution in the same pod on multi-year organic retainers.
  • Reports citation and mention progress alongside classic organic metrics (often using partner measurement tools).

Innovation

Grizzle’s key innovation is pairing mention generation and digital PR with on-page SaaS SEO and GEO on multi-year retainers. Measurement on some accounts uses partner tools such as Profound rather than a Grizzle-owned product.

4 - Anecdotes“Grizzle’s digital PR pod earned the trade mentions that finally showed up in Perplexity answers. On-page hubs alone had not moved citations.” ◆ “Strategy and execution sat in the same pod for the full multi-year retainer. We were not bounced between a planning deck and a separate writing vendor.” ◆ “Mention generation targets lived next to the content calendar. When a competitor owned a comparison thread, PR and writers moved on it in the same sprint.”
