Full-service SEO agency with AI/GEO practice · Austin, TX (remote team)
Organic growth agency founded 2012 by Ross Hudgens, layering GEO onto an established content marketing, SEO, and digital PR practice.
Bootstrapped by founder Ross Hudgens; crossed $100M in lifetime revenue in October 2024, then closed a $30M Series A (Landbase, Thesis Gold) three months later, in January 2025 — institutional funding arriving well after the company was already established.
Best for: Content-marketing-led growth with a deep, verifiable track record.
Twelve years of case studies give Siege Media a more specific proof set than most agencies here — Zendesk (94% traffic increase, $730K+ in traffic value), The Zebra ($7.77M traffic value, 1,580+ organic links), and Zapier ($6.1M traffic value increase) are named, dollar-denominated results rather than vague visibility claims, backed by a 4.9 rating across 46 Clutch reviews. The one recurring critique, independent of those numbers: a third-party comparison flagged Siege Media's reporting as a client-facing "black box" — clients see monthly summaries rather than real-time, self-service access to the data behind their proprietary tools (DataFlywheel, BlueprintIQ).
