When you look at Skale and MADX Digital side by side, the pitch sounds almost identical. Both talk about pipelines. Both talk about MRR. Both claim to go beyond vanity metrics.
But dig deeper and real differences emerge. Differences that matter when you’re deciding where to invest a $5,000 to $20,000+ monthly retainer.
This comparison breaks down both agencies across three dimensions: AI search visibility, revenue reporting, and technical SEO depth.
Skale is a remote-first B2B SaaS SEO agency founded in 2019. They’re known for content-led organic growth and have worked with recognizable SaaS brands like Pendo, Flodesk, and Paddle. Their approach ties SEO directly to pipeline, with a focus on high-intent content and conversion-focused landing pages.
MADX Digital is a London-based SEO agency founded in 2021 by Perry Steward and Toni Koraza. They focus on organic-first growth for B2B SaaS companies, with a particular emphasis on Generative Engine Optimization (GEO) alongside traditional SEO. They publish pricing openly, starting from $2,199 per month across three retainer tiers
Differentiator 1: AI Search Visibility (GEO)
Both agencies cover the SEO fundamentals well:
- Keyword research tied to buyer intent
- On-page optimization and technical audits
- Link building and digital PR
These are table stakes for any credible SaaS SEO agency. Where they diverge is on AI search.
As tools like ChatGPT and Perplexity reshape how B2B buyers discover vendors, the question has shifted. It’s no longer just “how do we rank on page one?” It’s “do we show up when a buyer asks an AI to recommend a solution in our category?”
Skale has strong foundations in traditional search. Their content strategy and link building work is well-regarded, with a track record of driving organic pipeline for established SaaS brands. Their GEO capability is still developing, with third-party analysis scoring it at 4/10 as of 2025. For companies where buyers still primarily discover solutions through Google, this may not be an immediate concern.
MADX Digital has built GEO into its core offering from day one. Every engagement includes:
- Structured content architecture for AI citation
- E-E-A-T and entity signal building for LLM trustworthiness
- AI citation tracking across ChatGPT, Perplexity, and Google AI Overviews
- Prompt-set testing to measure brand share-of-voice in AI-generated answers
Verdict: For traditional search, Skale delivers. For companies where AI search visibility is already a strategic priority, MADX Digital has the more developed offering.
Differentiator 2: Revenue Attribution and Reporting
Both agencies position themselves as revenue-focused rather than traffic-focused. How that looks in practice is where they differ.
Skale connects organic activity to MQLs and SQLs from the start. Their revenue-focused reporting has worked at scale for clients like Pendo and Paddle, and their pipeline attribution model is well established.
MADX Digital builds reporting that ties content output directly to demos, trial signups, and ARR. The goal is giving leadership teams a clear view of organic contribution to pipeline, without requiring manual exports across multiple tools. Teams can get answers to questions like:
- Which content drove the most SQLs last quarter?
- Are organic leads closing at a higher rate than paid leads?
- What’s the cost per organic sign-up by content type?
Neither agency delivers the fully automated revenue attribution an enterprise BI team might expect. The difference is in how proactively each builds the revenue story into ongoing reporting.
Verdict: Both agencies take reporting seriously. Skale’s track record with larger SaaS brands suggests strong pipeline attribution at scale. MADX Digital’s approach is more hands-on in building leadership-ready dashboards from day one.
Differentiator 3: Technical SEO Depth
Modern B2B SaaS sites come with specific technical challenges:
- JavaScript-heavy architectures that block Googlebot
- Core Web Vitals issues at the component level
- CMS-specific quirks across Webflow, HubSpot, and Next.js
- Complex crawl structures that waste crawl budget
These require genuine technical depth, not just surface-level audits.
Skale handles technical SEO as part of their broader engagement. Their work on site migrations is particularly well-regarded. Some clients note that deeper implementation work can depend on the client’s own dev team availability.
MADX Digital specializes in the CMS platforms most SaaS companies run on, including Webflow, HubSpot, and WordPress. Their technical scope covers:
- JavaScript rendering issues invisible to Googlebot
- Crawl budget optimization across large site architectures
- Core Web Vitals diagnosis at the component level
- SEO-safe site migrations with no ranking loss
Rather than handing over an audit and stepping back, they offer hands-on implementation support. For teams without a dedicated engineering resource, having the agency work directly with developers makes a practical difference.
Verdict: Both agencies handle technical SEO competently. MADX Digital’s hands-on implementation support stands out for leaner engineering teams.
