Free Shopify Tools that catch real bugs

A small collection of free, no-signup browser tools I built while auditing Shopify stores for clients. Each one solves a specific bug I kept seeing repeatedly across 100+ engagements: the kind of bug that costs international conversion rate, blocks Markets currency conversion, or burns crawl budget for months before anyone notices.

Shopify Robots.txt + AI Crawler Checker

Check which crawlers, including AI bots like GPTBot and ClaudeBot, your robots.txt allows.

AI crawlers silently blocked from training and citation, costing you organic brand mentions in ChatGPT, Perplexity, and Gemini answers
Googlebot or Bingbot blocked from key paths like /products/ or /collections/, hiding your catalog from search index
Missing Sitemap directive in robots.txt, leaving crawlers without a map to your most important pages
/policies/ disallow that ships with some Shopify setups flagged so you know whether it is intentional

Shopify Product Schema Validator

Validate your Shopify product schema and find the FAQ and content gaps that block AI-search citations.

Missing GTIN, brand, or MPN that prevent AI agents from matching your SKU across competing storefronts
Duplicate Product blocks from your theme and review app fighting over the same SKU, which crawlers merge wrong or ignore
AggregateRating without ratingValue or a reviewCount, which Google rejects and review-weighted recommendations skip
A price emitted as a string with a currency symbol or thousands separator that breaks price-comparison parsing
Offer with malformed priceCurrency (not ISO 4217) or non-standard availability enum, dropping the product from price-comparison flows
BreadcrumbList missing integer position values or malformed itemListElement, isolating the product from category-level agent queries
No FAQPage schema even though the page asks buyer questions, so AI engines cannot lift your Q and A into their answers
Content gaps on the five questions AI search extracts: what the product is, who it is for, how it compares, what it solves, and what buyers ask
