SEO agency pricing for ecommerce optimization: what to expect and how to evaluate

How ecommerce SEO agency pricing is structured

When evaluating SEO agency pricing for ecommerce optimization, US founders and growth teams should focus on outcomes - revenue, average order value (AOV), and customer acquisition cost (CAC) - not just rankings. Typical pricing models are monthly retainers, project-based fees, and performance-linked scopes. Each model is built to cover a combination of strategy, technical work, content, and measurement.

Common pricing models

• Monthly retainers: $2,000-$15,000+/month depending on scope and store size.
• Project-based: $5,000-$50,000 for site migrations, audits, or large technical builds.
• Hybrid or performance-linked: lower base retainer plus bonus tied to revenue or organic revenue growth (note: ranges vary by client).

Price varies by platform complexity (Shopify vs WooCommerce), SKU count, integrations (e.g., Stripe, Klaviyo), and required analytics work such as GA4, server-side tracking, or custom attribution. Agencies with deep analytics and server-side skills typically charge more but reduce wasted ad spend through cleaner attribution and better funnel optimization.

What’s included in an ecommerce SEO retainer

• Strategy: keyword prioritization mapped to TOF → MOF → BOF funnels and revenue impact modelling.
• Technical SEO: crawlability, site speed, structured data, canonicalization, and migration plans.
• On-page & content: category landing pages, product content, and conversion-oriented copy.
• Measurement & reporting: GA4, GTM, server-side tracking, and clean attribution for organic revenue.
• Ongoing testing: CRO tests at product and cart funnels to protect conversion rate while traffic scales.

Pricing drivers and what increases cost

• Large SKU catalogs and faceted navigation that require crawling strategy.
• Significant technical debt or migrations off legacy platforms.
• Advanced analytics needs: server-side tracking, custom ETL, or multi-domain setups.
• High-frequency content production or complex link-building campaigns.

Smaller stores often start at the lower end of the retainer range ($2k-$4k/month) focused on core technical fixes and priority content. Mid-market and enterprise ecommerce sites commonly engage at $6k-$15k+/month with dedicated cross-functional teams handling strategy, content, development, and analytics.

How to evaluate pricing against revenue impact

Rather than treating pricing as a cost center, model expected organic revenue lift and margin. Example: a $8,000/month retainer that improves organic revenue by $30,000/month at a 40% gross margin contributes an estimated $12,000/month gross profit - which may justify the investment. Always ask agencies for sample case studies and the assumptions behind projected revenue. Prebo Digital focuses on attribution clarity and MER to show how SEO contributes to profitable growth; learn about our approach on the about page at About Prebo Digital.

Scope alignment: Strategy → Build → Test → Scale → Report

• Strategy: prioritize revenue-driving pages and keyword funnels (TOF → MOF → BOF).
• Build: technical fixes, template updates, and content deployment.
• Test: CRO and content experiments to protect conversion while traffic changes.
• Scale: broaden content coverage and technical improvements guided by data.
• Report: clean GA4 and server-side attribution to measure organic revenue accurately.

If you want clarity on pricing for a specific store, agencies often provide scoped proposals after an initial audit. For direct next steps or to request a scoped estimate, visit the contact page at Contact Prebo Digital.
