CatalogAudit is a free tool that checks Shopify catalogs for feed, structured data, and AI-agent readiness issues. Its founder's 698-audit test shows gaps in most stores, which creates a clear opening for a catalog-cleanup service.

Why a Free Shopify Catalog Audit Tool Is Worth Your Attention
Most Shopify stores have messy product data, and now there is public evidence of how widespread the problem is. The founder of CatalogAudit, a free tool that checks Shopify catalogs for product feed, structured data, and AI shopping agent issues, ran 698 audits across 680 real stores and shared the results on Reddit. By the end of this article, you’ll know exactly what the tool checks, where the money is, and a step-by-step plan to turn free audits into paid catalog-cleanup work.
The timing matters. AI shopping agents are starting to browse, compare, and even add products to carts on behalf of shoppers. Stores whose catalogs are hard for machines to read risk being skipped. Most store owners haven’t caught up, and that gap is where a service provider can step in.
What CatalogAudit Actually Does
According to the founder, CatalogAudit inspects a Shopify store’s catalog in three areas:
- Product feeds: whether product data is complete enough for shopping channels
- Structured data: whether product markup includes attributes, offers, and policy details
- AI agent interaction: how automated shopping agents handle the store, including an automated add-to-cart check
Each audit produces two headline numbers on the tool’s own scoring system: a product feed score and an AI agent-readiness score, both out of 100. Each audit samples up to 25 products rather than scanning the full catalog.
The founder describes the tool as completely free. Check the official site for current features and any future pricing changes.
What 698 Audits Revealed
This is the part that makes the tool commercially interesting. Across 680 unique stores with a combined 359,890 products, the audits inspected 14,901 sampled products. Here’s what the founder reported:
| Issue found | Stores affected | Share of sample |
|---|---|---|
| Missing structured attributes (color, size, material) | 613 | 90% |
| Missing return or shipping policy in offer markup | 566 | 83% |
| Products without GTIN/barcode data | 542 | 80% |
| Missing image alt text | 516 | 76% |
| At least one failed agent add-to-cart check | 223 | 33% |
The average product feed score was 65/100, and the average AI agent-readiness score was 50/100.
The honest caveat
The founder is upfront about limitations, and you should be too when you pitch clients. Stores weren’t randomly selected, each audit samples a maximum of 25 products, and some things can’t be verified without access to Shopify’s backend. These are findings from a sample, not claims about the entire Shopify ecosystem. Still, when most audited stores share the same gaps, you have a strong starting hypothesis for any store you approach.
Where the Money Comes From
The tool itself is free, so you won’t earn by reselling it. You earn by doing the work the audit reveals. Here are three realistic models.
1. Catalog cleanup as a done-for-you service
Who sells: freelancers, VAs, or ecommerce generalists. To whom: small and mid-size Shopify merchants. How you get paid: per-project fee or per-product pricing.
The top issues in the table are fixable, repetitive tasks: adding color/size/material attributes, filling in GTINs the merchant already has, writing alt text, and making sure shipping and return policies appear in product markup. AI writing tools can speed up alt text and attribute extraction from existing descriptions, but you still need to review output for accuracy.
2. Audit-first outreach (the free report as a lead magnet)
Who sells: agencies and consultants. To whom: merchants who don’t know they have a problem. How you get paid: the audit opens the conversation; the cleanup or retainer is the paid offer.
Run the audit on a prospect’s store, then send a short, specific note: “Your AI agent-readiness score came back low, and your products are missing material and size attributes.” Specific findings convert far better than generic “I can help your SEO” pitches. Always frame scores as the tool’s own scoring, not an official Shopify rating.
3. Ongoing catalog maintenance retainers
Who sells: anyone who completed a first cleanup. To whom: stores that add products regularly. How you get paid: monthly retainer.
New products bring new gaps. Re-running the audit periodically gives you a simple before-and-after report to justify a recurring fee. Set your pricing based on your market and catalog size; there’s no benchmark in the source data.
Why the Difficulty Is “Medium”
The audit is free and quick, which makes getting started easy. The harder parts are:
- Sales: you still have to find merchants and earn trust. A free report helps, but outreach takes consistent effort.
- Technical knowledge: structured data and product feeds aren’t beginner topics. You’ll need to understand how Shopify themes output product markup, or partner with someone who does.
- Access limits: as the founder notes, some issues can’t be confirmed without backend access. You’ll need the merchant’s permission to verify and fix them.
- Sampling: a 25-product sample won’t catch everything in a large catalog. Scope paid work around a full review, not just the audit output.
Results depend entirely on your execution, niche, and outreach volume. There’s no guaranteed income here, just a clear, evidence-backed problem to solve.
Practice on Your Own Store First
Before pitching clients, it helps to have a store you control so you can see how fixes change the scores. If you don’t have one, you can spin up a Shopify test store, add sample products, run CatalogAudit, fix the gaps, and audit again. That before-and-after becomes your first case study.
How to Do It: Your Step-by-Step Checklist
- Set up a practice environment. Use an existing store or create one with Shopify. Add 20-25 products with deliberately incomplete data.
- Run your first audit. Note the product feed score and AI agent-readiness score, plus which issues appear.
- Fix the top four issues. Add structured attributes (color, size, material), GTINs where available, image alt text, and shipping/return policy details in offer markup.
- Re-audit and document. Screenshot both reports. This is your proof of skill.
- Pick a niche. Choose a product category where attributes matter a lot, such as apparel or home goods, so the value of cleanup is obvious.
- Build a prospect list. Collect 20-30 Shopify stores in that niche.
- Audit each prospect. Pull out two or three specific findings per store.
- Send personalized outreach. Lead with their findings, explain the caveat that scores come from the tool’s own system and a sample of products, and offer a clear fix.
- Scope the paid project. Request access, review the full catalog beyond the sample, and quote based on product count and complexity.
- Offer a maintenance plan. After delivery, propose periodic re-audits and fixes for new products.
