Siege Media is a content-led SEO agency that produces long-form articles and visual assets and runs link-earning campaigns around them. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, and the team ships technical SEO, content, schema, internal linking, and off-site citations while tracking visibility weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. Both produce content. The difference is that Geology ties every page it writes or fixes to measured rankings and AI citations, and it works on the pages you already have as well as new ones.

What Siege Media does
Siege Media is a content marketing and SEO agency founded by Ross Hudgens, focused on producing long-form articles, visual content, and the links that support them. The agency is known for case studies with Asana, Zillow, and Mailchimp, and for a team that combines writers, editors, and designers under one roof. The work includes original research, custom illustrations, and a process built around topic clusters. Reviews on Clutch and industry roundups highlight quality and consistency. The trade-off is what you would expect from a production agency: the cycle time is set by the editorial calendar, and the focus is on creating new pages rather than diagnosing how an existing site shows up in AI answers.
What Geology does differently
Geology measures how your site appears in Google and in AI answers, then ships the fixes and the new content in the same program. Page audits flag articles an AI is misreading. Prompt research captures the queries your buyers actually run. The team writes and publishes content against those gaps, AI agents apply common fixes (schema, FAQ structure, internal linking), and off-site citation work builds the sources AI engines trust. That means your existing library gets made legible to ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, and new pages are written to be cited from day one. For a mid-size B2B SaaS client, that approach drove 65% organic growth in six months.
Pricing
Siege Media runs a custom monthly retainer scoped to content volume, design, and link work, typically in the mid five figures per month. Geology starts at $3,000 a month and covers technical SEO, content, and GEO execution.
When Siege Media fits
If your priority is custom-illustrated content assets and digital PR campaigns built around original research for brand awareness, Siege Media's writer, designer, and outreach bench is set up for that kind of production. Geology does not sell PR campaigns. For the SEO and GEO work itself (technical fixes, search content, schema, off-site citations, and AI visibility), Geology covers it.
When Geology wins
If you want visibility in Google and in AI answers, Geology wins. The measurement tells you which pages and prompts are working, and the team ships the content and fixes that move the numbers this quarter, without waiting on a long editorial calendar.
