Best Amazon Marketing Agencies in Toronto for Sellers in 2026

Amazon’s 2026 algorithm update prioritizes profitability signals, conversion quality, and AI-aligned content over traditional keyword stuffing. Agencies that understand this shift will protect your margins while competitors burn cash chasing vanity metrics.

Selling on Amazon in 2026 isn’t what it used to be. The platform now runs on AI-first enforcement systems, smarter algorithms that prioritize engagement quality over keyword density, and automated systems that can suppress your listings without warning.

Add to that: higher ad costs, stricter compliance requirements, tariff unpredictability, and Amazon’s new AI shopping assistant Rufus reshaping how customers discover products. The A10 algorithm update now weighs conversion rate, retail readiness, and contribution margin signals more heavily than ever before.

Sadly, not all agencies understand the realities of Amazon today. Some focus only on PPC management. Others treat Amazon like social media, optimizing for impressions instead of profit. Very few combine data-driven advertising, conversion-focused creative, and margin protection strategy in a way that actually improves your bottom line.

In this guide, we’ll break down the best Amazon marketing agencies in Toronto for 2026, what makes them stand out in this new algorithmic environment, and how to choose the right partner based on your stage of growth.

Why Hire An Amazon Marketing Agency in 2026?

Marketing on Amazon today depends on how well your ads, listings, pricing, inventory, and backend data harmonize with Amazon’s AI-driven systems. A good agency understands that Amazon’s COSMO ranking engine and Rufus assistant now prioritize buyer intent and context over mechanical keyword matching.

First, they think beyond PPC. Advertising matters, but ads alone can’t fix poor conversion rates, weak creatives, or bad keyword indexing. Amazon’s 2026 algorithm update penalizes aggressive advertising that drives low-quality traffic. If your listing doesn’t convert, scaling ad spend only makes the losses bigger and triggers algorithmic suppression.

Second, they focus on contribution margin, not vanity metrics. It’s easy to celebrate higher sales. It’s harder to make sure you’re keeping profit after ad spend, Amazon fees, refunds, storage costs, and the hidden margin erosion that silently cuts 5-10% from your bottom line. The Buy Box algorithm now weighs price competitiveness more heavily, forcing sellers to choose between margin protection and visibility.

Third, they understand how Amazon’s AI systems work in 2026. Automated enforcement makes decisions before humans review your case. The platform now uses OCR (optical character recognition) to scan your images for context. Sponsored Brands, Sponsored Display, DSP retargeting, search term harvesting, creative testing, and backend keyword optimization are all part of a structured growth strategy that accounts for AI-aligned content requirements.

And finally, they work with real-time data and structured testing. They test, adjust, and optimize based on performance signals that matter to Amazon’s profitability algorithms, not opinions or outdated tactics from 2024.

When evaluating Amazon agencies in Toronto, ask yourself:

• Do they talk about profit and contribution margin, or just revenue and ACoS?
• Do they audit listings and fix conversion issues before scaling ads?
• Do they understand Amazon’s 2026 algorithm changes (A10, Rufus, COSMO, AI enforcement)?
• Do they have a structured launch and scaling framework that accounts for retail readiness?
• Can they show performance improvements with real case studies and client results?

And keep in mind that the right partner won’t promise overnight success. They’ll show you a clear roadmap built around sustainable growth, margin protection, and algorithmic alignment. They understand that Amazon’s automated systems can suppress listings within minutes if they detect inconsistencies, and they build strategies that prevent that from happening.

Now, let’s look at the Toronto agencies doing this well in 2026.

Top Amazon Marketing Agencies in Toronto for 2026

1. Pro Marketer

If you’re looking for an agency that understands both performance marketing and marketplace economics in the age of AI-driven algorithms, Pro Marketer is the best place to start.

They don’t treat Amazon as “just another ad platform.” They treat it as a profit engine that requires strategic alignment with Amazon’s 2026 algorithm priorities. What makes them different is their focus on contribution margin and retail readiness before scaling paid campaigns.

Before they touch your ad budget, they audit:

• Listing conversion rates and A+ content engagement signals
• Keyword indexing, backend structure, and semantic search optimization
• Creative quality (images optimized for OCR scanning, lifestyle context, infographics)
• Pricing strategy relative to competitors and Buy Box algorithm requirements
• Catalog health, variation structure, and attribute accuracy
• Inventory consistency and fulfillment reliability (critical ranking factors in 2026)

Only after that foundation is solid do they scale paid campaigns. Their Amazon services include:

• Sponsored Products, Sponsored Brands, and Sponsored Display management with AI-assisted bidding
• Amazon DSP (Demand-Side Platform) for retargeting and off-Amazon audience reach
• Structured keyword harvesting, search term optimization, and bid strategy testing
• Listing optimization and conversion-focused creative direction aligned with Rufus/COSMO requirements
• Launch strategy for new SKUs that accounts for Amazon’s updated “honeymoon period” mechanics
• Profit tracking and reporting built around real margins, not surface-level metrics
• Inventory-aware scaling strategies that prevent stockouts (which tank algorithmic momentum in 2026)
• External traffic integration to boost rankings, lower CPCs, and improve long-term discoverability

They’re particularly strong for:

• Canadian brands scaling from 6 to 7 figures who need structured, margin-aware growth
• Sellers tired of high ACoS with low profit who need efficiency optimization, not just more ad spend
• Brands launching new products that need AI-aligned listing structure and strategic traffic planning
• Founders who want clear reporting, accountability, and a partner who understands 2026’s algorithmic realities

Pro Marketer focuses on stable growth, better account structure, predictable scaling, and protection against Amazon’s automated enforcement systems. They understand that in 2026, operational excellence and retail readiness are ranking factors, not just nice-to-haves.

2. Stryve Marketing

Stryve works closely with B2B companies, tech firms, and professional service brands. While not exclusively Amazon-focused, here’s what they do well:

• Strategic marketing planning aligned with business objectives
• Brand positioning and messaging development
• Content marketing and storytelling (increasingly important for AI-driven discovery)
• Digital advertising and performance campaigns across multiple channels
• Website design and development focused on usability and conversion
• Ongoing WebOps and digital support for integrated growth strategies

Their team emphasizes integration. That means paid media, website performance, content, and branding are connected under one strategy, which aligns with Amazon’s 2026 focus on cross-channel signals and external traffic validation.

Stryve is based in the Waterloo-Kitchener region and serves clients across Ontario. Their approach is strategic, collaborative, and structured, especially for businesses that value planning, positioning, and long-term brand building alongside marketplace growth.

3. BrandLume

BrandLume is a Toronto-based digital marketing agency built specifically for ecommerce brands with a focus on Amazon, Walmart, and marketplace growth. Unlike generalist agencies, BrandLume centers its services around driving measurable sales and profitability on ecommerce platforms.

Their philosophy aligns with 2026 realities: Amazon’s success isn’t about spending more on ads, it’s about optimizing every aspect of your customer journey to align with AI-driven ranking systems.

Here’s what they do well:

• Marketplace listing optimization with focus on conversion rate and engagement quality
• Amazon PPC and DSP management with structured testing frameworks
• Data-driven strategy that accounts for profitability signals and contribution margin
• Brand Store and A+ content development optimized for OCR scanning and semantic search
• Reporting and insights focused on metrics that matter: conversion rate improvement, keyword rank movement, and profitability

BrandLume has built its reputation by focusing on the metrics Amazon’s algorithm actually rewards in 2026: conversion quality, retail readiness, and catalog health. They understand that poorly structured catalogs lose traction even with historical rank, and they fix that foundation before scaling spend.

4. Accrue Agency

The Accrue Agency positions itself as a full-service Amazon growth partner with a strategic approach that mirrors what Amazon’s 2026 algorithm prioritizes. Here’s what they do well:

• Sponsored Products, Sponsored Brands, and Amazon DSP management
• Retail operations support, including inventory management and account health monitoring (critical for avoiding automated enforcement)
• Listing optimization and branded storefront development
• Creative development focused on conversion and AI-aligned content structure
• Structured analytics and performance reporting that connects ad performance to profitability

They emphasize strategy before scaling. Which means they review performance data, identify inefficiencies, and align ad investment with business objectives rather than chasing surface-level growth that erodes margins.

The Accrue Agency focuses on full-funnel Amazon management rather than standalone PPC execution. They understand that in 2026, Amazon increasingly connects organic and paid signals, and they optimize accordingly.

5. Webtonic

Web Tonic is a performance-driven, 360-degree digital marketing agency. They’ve built a multi-disciplinary team designed to handle paid media, SEO, web design, and branding with an integrated approach.

Here’s what they do well:

• Multi-channel paid advertising (including Amazon, Google, Meta) with cross-platform attribution
• SEO and organic growth strategies that complement paid efforts
• Conversion-focused web design that supports DTC and marketplace integration
• Branding and creative support for cohesive brand storytelling
• Performance tracking and dashboards that connect Amazon performance to broader business goals

They are perfect for brands that want full-stack digital growth, ecommerce owners aiming for sustainable traffic and sales lift across channels, and businesses expanding visibility internationally. Their integrated approach aligns with Amazon’s 2026 emphasis on external traffic and cross-channel validation.

Understanding Amazon’s 2026 Algorithm Changes

Before choosing an agency, it’s critical to understand what changed in 2026 and why it matters for your agency selection.

Amazon’s A10 algorithm update and the introduction of AI systems like Rufus (shopping assistant) and COSMO (ranking engine) have fundamentally shifted how products get discovered and ranked:

AI-Driven Discovery: Rufus moves search away from keyword matching toward intent and outcomes. COSMO understands buyer intent, context, use case, and underlying needs. Success now depends on whether your listing clearly communicates what the product is, who it’s for, what problem it solves, and why it’s trustworthy.

OCR Image Scanning: Amazon’s AI agents use optical character recognition to read your images. Your infographic text, packaging claims, lifestyle scenes, and product use cases all get scanned and indexed. If you’re selling a beach umbrella, your images must clearly show a beach umbrella on a beach for proper classification and recommendation.

Engagement Quality Over Clicks: The algorithm now cares more about what happens after the click: add-to-cart rate, session length on listings, scroll and interaction with A+ content, and repeat purchase behavior. Click-through rate alone doesn’t cut it anymore.

Retail Readiness as Ranking Factor: In-stock consistency, competitive landed price, Prime eligibility, fulfillment reliability, and clean catalog structure now directly impact rankings. Operational gaps like frequent stockouts or erratic pricing tank momentum faster than ever.

Profitability Signals: Products that drive strong contribution margin, fewer returns, and high customer satisfaction gain more algorithmic support. This affects both organic visibility and how aggressively Amazon shows your ads.

External Traffic Validation: Traffic from social, email, and DTC that converts well on Amazon helps validate product relevance and momentum. Off-Amazon traffic now matters more than ever because AI discovery is increasing the scarcity and cost of on-platform ad placements.

Automated Enforcement: Amazon’s systems operate on an AI-first model. When something triggers a compliance flag, an automated system suppresses your listing, suspends your account, or blocks inventory within minutes, often without human review. Your first human interaction is usually your appeal, after you’ve already lost sales and ranking momentum.

The agencies that win in 2026 understand these shifts and build strategies around them. They don’t just manage PPC campaigns in isolation; they optimize for the entire ecosystem that Amazon’s algorithm rewards.

So, Which Agency Is Right for You?

Your stage determines the type of agency you need.

If you’re an early-stage Amazon seller launching your first SKUs, you need structure, clean listings optimized for AI discovery, proper keyword research that accounts for semantic search, and good budget control. You need an agency that will audit your foundation before spending a dollar on ads.

If you’re already generating consistent sales but your margins aren’t great, the problem isn’t traffic. It’s efficiency. You need an agency that understands TACoS (Total Advertising Cost of Sale), contribution margin, when NOT to increase ad spend, and how to optimize for profitability signals that Amazon’s algorithm rewards.

If you’re scaling past seven figures, you need layered campaigns, creative testing cycles, inventory-aware scaling strategies, DSP retargeting, external traffic integration, and reporting that goes beyond surface metrics. You need a partner who understands that in 2026, Amazon connects organic and paid signals, and optimization requires a holistic approach.

The right partner for you is the one that aligns with your stage and understands 2026’s algorithmic realities. Before signing, ask:

• How do you protect contribution margin while scaling, especially with the Buy Box algorithm weighing price more heavily?
• What happens if ad spend increases but profit drops due to algorithmic changes or enforcement actions?
• How do you approach listing optimization and retail readiness before expanding paid campaigns?
• How do you account for Amazon’s AI systems (Rufus, COSMO, OCR scanning, automated enforcement) in your strategy?
• Can you show case studies where you improved profitability, not just revenue?
• How do you integrate external traffic and cross-channel signals to support Amazon performance?
• What’s your approach to structured testing and AI-assisted bid optimization?

And if you’re looking for a Toronto-based team that prioritizes structured scaling, contribution margin discipline, algorithmic alignment, and performance accountability in the age of AI-driven Amazon, there are a few strong options like Pro Marketer that stand out.

Wrapping Up

Toronto has no shortage of marketing agencies. But Amazon in 2026 is not just another channel. It requires a partner who understands how AI-driven discovery, automated enforcement, profitability signals, retail readiness, and cross-channel integration work together.

The A10 algorithm, Rufus, COSMO, and automated compliance systems have raised the bar. Agencies that still treat Amazon like it’s 2023 will burn your budget chasing tactics that no longer work. The winners in 2026 are agencies that understand Amazon’s shift toward engagement quality, contribution margin, and AI-aligned content.

Before you hire anyone, be clear about your goal: Are you launching with proper foundation? Are you fixing profitability issues? Or are you scaling aggressively with margin protection?

Your stage determines the type of agency you need. And if you choose wisely, the agency will help you build an Amazon business that compounds over time, protected from algorithmic volatility and positioned for sustainable growth in an AI-first marketplace.

Frequently Asked Questions

What should I look for in an Amazon marketing agency in 2026?

Look for agencies that prioritize contribution margin over revenue growth, audit listings before scaling ads, understand Amazon’s A10 algorithm and AI systems (Rufus, COSMO, OCR scanning), have structured testing frameworks, and can show real profitability improvements in case studies. Avoid agencies that only manage PPC in isolation without addressing retail readiness, catalog health, or conversion optimization.

How much does an Amazon marketing agency cost in Toronto?

Most reputable Amazon agencies charge either a percentage of ad spend (typically 10-20%) or a flat monthly retainer ($2,000-$10,000+ depending on services and scale). Full-service agencies that handle listing optimization, creative, DSP, and strategic consulting typically charge higher fees but deliver better ROI by optimizing the entire funnel, not just ads. Expect to commit 3-6 months for meaningful results.

What’s the difference between Amazon PPC management and full-service Amazon marketing?

PPC management focuses solely on running Sponsored Products, Sponsored Brands, and Sponsored Display campaigns. Full-service Amazon marketing includes listing optimization, A+ content creation, brand store development, creative testing, inventory planning, retail readiness audits, external traffic integration, DSP retargeting, and strategic consulting. In 2026, full-service is critical because Amazon’s algorithm connects organic and paid signals – you can’t optimize ads in isolation.

How has Amazon’s 2026 algorithm update changed what agencies need to do?

The A10 algorithm update and AI systems like Rufus and COSMO prioritize engagement quality, retail readiness, and profitability signals over traditional keyword stuffing. Agencies now must optimize for conversion rate, add-to-cart behavior, session length, catalog health, in-stock consistency, contribution margin, and AI-aligned content structure. OCR image scanning means creative must clearly communicate product context. Automated enforcement means compliance and operational excellence are ranking factors, not afterthoughts.

Should I hire an agency if I’m just starting on Amazon?

If you’re generating under $25K/month, the ROI may not justify agency costs yet. Focus on fundamentals: proper listing structure optimized for AI discovery, clean keyword research, quality images that pass OCR scanning, competitive pricing, and inventory management. Once you’re consistently above $50K/month and struggling with profitability or scaling, that’s when an agency makes sense. They’ll audit your foundation, fix inefficiencies, and scale profitably rather than just spending more on ads.
