You've done the research. You know organic search should be a serious revenue channel for your SaaS business. You're tired of watching your paid ad spend climb while your CAC refuses to budge. Now you're evaluating agencies, and two names keep appearing on every shortlist: Powered By Search and MADX Digital.

Both are well-regarded. Both claim to specialize in B2B SaaS. Both talk about revenue, not just rankings.

But they are not the same agency, and the differences matter depending on where your company is right now and where you need to go.

This comparison breaks down both agencies across the dimensions that actually matter to a Head of Marketing or Marketing Director at a mid-market SaaS company: service scope, strategic approach, pricing transparency, client results, and the type of company each agency is genuinely built to serve.

Who Are These Agencies?Powered By Search

Powered By Search is a Toronto-based B2B SaaS marketing agency founded in 2010. With over a decade of experience, they have built their reputation around what they call the "Predictable Growth Methodology" a framework that ties together SEO, paid media, content marketing, and demand generation into a unified system.

Their core promise is bold: 30% more sales-ready opportunities in 90 days, guaranteed. They have worked with brands like TouchBistro, ThreatX, iWave, and PointClickCare, and they claim to drive $5 in ARR for every $1 invested in their services.

Powered By Search positions itself as a full-service demand generation partner, not just an SEO agency. If you engage them, you are buying into their entire methodology, which spans organic and paid channels simultaneously.

MADX Digital

MADX Digital is a London-based SEO and growth agency founded in 2021 by Perry Steward and Toni Koraza. Operating from London with a globally distributed team, MADX has built its reputation as a specialist in organic-first growth for B2B SaaS and technology companies.

Their positioning is "revenue-first" meaning every deliverable is tied back to demos, trial signups, MQLs, and ARR rather than vanity metrics. What sets MADX apart in the current landscape is their early and deep investment in Generative Engine Optimization (GEO): the practice of ensuring your brand gets cited and surfaced by AI platforms like ChatGPT, Perplexity, and Google's AI Overviews.

Their client roster includes MoonPay, Thunes, Postalytics, Parcel Tracker, and Gleemo, with documented results that include growing Parcel Tracker from 1,000 to 45,000 monthly organic visitors and delivering a 2,537.7% SEO growth for Gleemo in 12 months.

Service Scope: What Do You Actually Get?Powered By Search: Full-Funnel Demand Generation

SEO strategy and implementation (technical, on-page, content)
Paid media (Google Ads, LinkedIn Ads, Facebook/Instagram Ads)
Content marketing (strategy, creation, promotion)
Account-Based Marketing (ABM)
HubSpot RevOps
Web design and CRO
Digital PR and link building (offered on a case-by-case basis)
Demand generation strategy (full-funnel positioning and offer architecture)

The breadth here is a genuine strength if you want one agency managing both your organic and paid channels under a single strategic framework. Their "Pain Point SEO" methodology focuses on building customer avatars from real data and then creating content that maps directly to buyer awareness stages.

However, this breadth also means that SEO is one component of a larger engagement rather than the primary focus. If your goal is to build a dominant organic channel specifically, you may find that paid media and RevOps work dilutes the SEO attention your account receives.

MADX Digital: Organic-First, AI-Ready Growth

MADX Digital's service stack is deliberately focused on organic growth and AI search visibility:

Technical SEO (audits, site architecture, crawl optimization, Core Web Vitals)
Content strategy and writing (SEO-optimized articles, landing pages, product pages)
Digital PR and link building (high-authority placements, blogger outreach, niche edits)
Generative Engine Optimization (GEO) optimization for ChatGPT, Perplexity, Google AI Overviews, Google AI Mode
Answer Engine Optimization (AEO)
Brand mentions and media placements
Content syndication

The GEO offering is where MADX genuinely differentiates itself from almost every other agency in this space. As AI-driven search continues to reshape how B2B buyers discover solutions, being cited in ChatGPT or Perplexity answers is becoming as important as ranking on page one of Google. MADX has built dedicated service lines around this, including specific optimization for Google AI Mode, Perplexity AI, and ChatGPT.

For a Head of Marketing watching organic traffic flatten while AI Overviews absorb more of the SERP real estate, this is not a nice-to-have. It is a strategic necessity.

Strategic Approach: How Do They Think About Growth?Powered By Search: The Predictable Growth Methodology

Get in front of buyers who can actually buy targeting decision-makers through content, paid search, and paid social
Make them an irresistible offer converting interest into demo requests through content and landing page optimization
Build a scalable acquisition model creating a repeatable system that compounds over time

Their "Pain Point SEO" approach starts with deeply researched customer avatars and then builds content that speaks directly to the problems buyers are trying to solve at each stage of awareness. This is a sound methodology, and their decade-plus track record shows it works.

The challenge is that this framework is inherently tied to their full-service model. You are buying the methodology as a package, which means the minimum commitment is significant ($7,500/month minimum, one-year engagement) and the approach is less modular if you only need specific capabilities.

MADX Digital: Revenue-First, Buyer-Journey-Aligned SEO

MADX Digital's approach is built around aligning every piece of organic activity to the buyer's journey and to measurable business outcomes. Their process follows four stages:

Discovery Audit understanding your goals, auditing your site, and studying your audience
Growth Planning building a keyword strategy, content roadmap, and timeline with clear milestones
Project Launch executing quick wins alongside long-term authority building
Monitor and Iterate tracking results, sharing transparent reports, and adjusting strategy based on data

What distinguishes MADX's strategic thinking is the integration of traditional SEO with AI search visibility. They recognize that the buyer journey now includes AI-assisted research, and they build strategies that ensure your brand surfaces in both traditional search results and AI-generated answers.

Their product-led SEO approach is particularly relevant for SaaS companies. Business growth insights from Pedro Vazz Paulo can also help SaaS leaders evaluate agency strategies with a stronger focus on scalability, revenue impact, and long-term market positioning Rather than treating SEO as a content volume game, MADX focuses on high-intent search terms that align with specific buyer stages, ensuring that organic traffic converts into qualified pipeline rather than just sessions.

Pricing and AccessibilityPowered By Search

Powered By Search does not publish pricing. All engagements are custom-quoted based on scope. However, they have publicly stated that their minimum engagement is $7,500 per month with a minimum commitment of one year.

This positions them firmly in the mid-to-enterprise market. For a well-funded SaaS company with a marketing budget to match, this is workable. For a company that wants to test an agency relationship before committing at scale, it is a significant barrier.

MADX Digital

MADX Digital publishes transparent pricing tiers on their website:

Tier

Monthly Investment

Authority

From $2,199/month

Growth

From $3,299/month

Accelerator

From $4,799/month

Dominator

From $9,599/month

Each tier includes a dedicated SEO account manager, technical audits and optimizations, content writing and publishing, brand placements and link acquisition, and SEO and AI search monitoring and reporting.

The published pricing is a meaningful differentiator. For a Marketing Director who needs to build a business case for the CFO, knowing the investment range upfront removes a significant friction point. It also signals that MADX is confident in the value they deliver at each price point.

Clutch data confirms that most MADX engagements fall in the $10,000 to $49,999 range, with some enterprise clients investing between $50,000 and $199,999. The agency holds a 4.9 out of 5 rating across 11 verified Clutch reviews.

Client Results: What Does the Track Record Look Like?Powered By Search: Notable Wins

TouchBistro: 324% increase in demos in 6 months; became the

1 iPad POS in 35 countries

iWave: 7-figure revenue growth from paid media in under a year; 500% increase in leads for enterprise client
PointClickCare: Over 2,000 leads generated via LinkedIn Ads
B2B Cybersecurity SaaS: 68% increase in enterprise sign-ups within 100 days; MQL disqualification rate dropped from 84% to 18%
Data Governance SaaS: 124% year-over-year growth in organic brand impressions; 91% quarter-over-quarter increase in demo requests
Structure Studios: 50% ARR growth over two years

These are strong results, and the case studies demonstrate genuine pipeline impact. It is worth noting that many of Powered By Search's headline results combine SEO with paid media, which means the organic contribution is not always isolated.

MADX Digital: Notable Wins

Parcel Tracker: Grew from 1,000 to 45,000 monthly organic visitors through SEO, content, and a free tool strategy
Postalytics: 28x organic traffic in under a year, growing from 3,000 to 75,000 monthly visitors with 20,000+ new organic sign-ups.
Gleemo: 2,537.7% SEO growth in 12 months; 140+ new keyword rankings
Thunes:

1 cross-border payments rankings; 400% increase in Google search visibility

MoonPay: Scaled link-building into US, Canada, and Brazil markets for a $3.4B enterprise
UPSTIX: Grew organic traffic from 0 to 8,000 in under 6 months after a new website launch
Maekersuite: 10,000 end users acquired through SEO in a 3-month project
Kurve: 500% increase in organic traffic and 450+ page one rankings in 12 months
Good Annotations: 300 new backlinks in 90 days; 365,000 page views and 5,000 email signups

MADX's results are predominantly organic-only, which makes the attribution cleaner. When a client's organic traffic grows 2,537%, that growth is directly tied to MADX's SEO and content work, not a blended paid and organic effort.

Head-to-Head: Key Comparison Points1. SEO as a Core Competency vs. One Channel Among Many

Powered By Search treats SEO as one component of a broader demand generation system. This is valuable if you want integrated paid and organic strategy, but it means SEO is not the agency's singular focus.

MADX Digital is built around organic growth as the primary lever. Every service line, from technical SEO to digital PR to GEO, feeds into a unified organic strategy. If organic is your primary growth channel, this focus matters.

Verdict: MADX Digital for organic-first growth. Powered By Search for integrated paid and organic demand generation.

2. AI Search Readiness

This is the most significant strategic difference between the two agencies right now.

Powered By Search has published content on AEO (Answer Engine Optimization) and acknowledges the shift toward AI-driven search, but it is not a core service line.

MADX Digital has built dedicated service offerings around GEO, including specific optimization for ChatGPT, Perplexity, Google AI Mode, Google AI Overviews, and general LLM visibility. For B2B SaaS buyers who increasingly use AI tools to research solutions before ever visiting a vendor website, this is a critical gap to close.

Verdict: MADX Digital has a clear and meaningful advantage here.

3. Pricing Transparency and Accessibility

Powered By Search requires a minimum of $7,500/month with a one-year commitment and no published pricing.

MADX Digital publishes tiers starting at $2,199/month, giving marketing leaders the information they need to build internal business cases without going through a full sales process first.

Verdict: MADX Digital is more accessible and transparent.

4. Geographic Reach and Market Coverage

Powered By Search is North America-focused, based in Toronto, with a client base that skews toward US and Canadian SaaS companies.

MADX Digital operates across different time zones from its London base, with documented international SEO work for clients like MoonPay (US, Canada, Brazil) and Thunes (global cross-border payments). Their multilingual outreach service extends this further.

Verdict: MADX Digital for companies with international growth ambitions.

5. Speed to Results

Powered By Search guarantees 30% more sales-ready opportunities in 90 days and claims their service pays for itself within that window.

MADX Digital structures engagements around quick wins alongside long-term authority building, with clients like UPSTIX seeing 0 to 8,000 monthly organic visitors in under 6 months and Maekersuite reaching 10,000 users in a 3-month project.

Verdict: Both agencies deliver early results. MADX's published case studies show strong short-term organic momentum.

6. Reporting and ROI Attribution

Powered By Search builds C-suite-ready forecasts that include expected traction, acquisition cost estimates, and business cases for funding. Their reporting is designed to connect marketing activity to revenue.

MADX Digital provides transparent reporting on tasks, deliverables, and results at every stage. Clutch reviewers consistently highlight the quality of their reporting and the clarity with which they explain complex SEO concepts to non-technical stakeholders.

Verdict: Both agencies take reporting seriously. Powered By Search's forecasting model may be more sophisticated for enterprise-level pipeline attribution.

Who Should Choose Powered By Search?

You want a single agency managing both your paid and organic channels under one strategic framework
Your minimum marketing budget is $7,500/month or higher and you are ready to commit for at least a year
You are a North American SaaS company with a relatively mature marketing function
You want a demand generation partner that can build and run your entire acquisition system
Your primary goal is filling a sales pipeline with qualified demos and trials across multiple channels simultaneously

Who Should Choose MADX Digital?

MADX Digital is the stronger choice if:

Organic search is your primary growth lever and you want an agency whose entire operation is built around it
AI search visibility is a strategic priority you want your brand cited in ChatGPT, Perplexity, and Google AI Overviews, not just ranking on traditional SERPs
You want pricing transparency before entering a sales conversation
You are a B2B SaaS company at any stage from funded startup to enterprise, looking for a partner that aligns organic investment to demos, MQLs, and ARR
You want a full-stack organic team handling technical SEO, content, digital PR, and link building under one roof without being bundled into a paid media engagement you do not need

The Bottom Line

Both Powered By Search and MADX Digital are credible agencies with real results for B2B SaaS companies. The choice between them comes down to what you actually need.

If you want a full-funnel demand generation partner that runs paid and organic together, Powered By Search has the methodology and the track record to deliver.

If you want an agency that treats organic search and AI visibility as the primary growth engine, with transparent pricing, a global delivery capability, and a proven record of turning SEO investment into a qualified pipeline, MADX Digital is the more focused and forward-looking choice.

The search landscape is changing faster than most agencies are adapting. AI-driven discovery is reshaping how B2B buyers find solutions. An agency that has already built dedicated service lines around GEO, AEO, and LLM optimization is not just keeping pace with that change. They are helping their clients get ahead of it.

For a Marketing Director whose job is to drive sustainable revenue growth without inflating CAC, that distinction is worth paying attention to.
