Conversion-first marketplace optimization for Los Angeles sellers. Listing audits, CRO testing, PPC alignment, and reconciled revenue reporting - designed to lower CAC and lift profitable growth.
Optimizations focused on conversion and profit, not vanity metrics.
Server-side tracking and reconciled reports that show real channel contribution.
Scoped plans and testing roadmaps designed for Los Angeles sellers.
If you sell on Amazon, eBay, Etsy, or other marketplaces and search for affordable online marketplace optimization in Los Angeles, you need a structured approach that prioritizes profit, not just impressions. Prebo Digital builds listing systems that improve discoverability, increase conversion rates, and tighten attribution so you can measure true revenue impact.
Our approach is strategy → build → test → scale → report. That means an initial audit of listings and analytics, prioritized optimizations that move the needle on profit per acquisition, iterative testing of titles, images, and bullets, and clear monthly reporting that ties activity back to revenue. For an overview of our service set and tracking capabilities, see our Services Overview.
Optimizations are mapped to each funnel stage so every change has a measurable goal:
Example US scenario: a mid-market Shopify brand that lists on Amazon and eBay can expect listing setup and baseline optimization to cost roughly $1,500-$4,000 (estimate). Ongoing monthly optimization and CRO testing are typically $1,200-$4,500 per month depending on catalog size and test velocity (estimates). These ranges are illustrative and will vary by product complexity and advertising spend.
We also connect marketplace outcomes to your broader revenue picture with server-side tracking and clean attribution. If you want to understand how marketplace sales interact with on-site retention and email flows, review how Prebo Digital structures tracking and data pipelines on our homepage.
For Los Angeles-based sellers seeking efficient, revenue-focused work, our retainers are built around measurable outcomes. Typical inclusions:
What we do not include in a standard optimization retainer: manufacturing, product photography on-site, or third-party logistics handling. Those can be scoped separately. Our focus is on the listing and funnel mechanics that increase measurable margin and lifetime value.
Marketplace signals are noisy. We combine marketplace analytics with server-side tracking and ETL to produce reconciled monthly revenue reports and channel-attributed ROAS that reflect real profit. For technical capabilities and tracking services, see our services page and read about our agency approach on the About Us page.
Practical example: a Los Angeles seller spending $8,000/month in marketplace ads who reduces CAC by 15% through listing and bidding optimizations can reallocate that budget to scale profitable SKUs. Savings and reallocations are shown in reconciled reports so teams can make data-driven buy/sell decisions.
Pricing is designed to be accessible to growing sellers while remaining test-driven. Ask for a scoped plan if you manage large catalogs or need Amazon-exclusive services.
