## Free tools for Shopify merchants

- [CRO Audit for Shopify stores](https://ninety9.dev/cro-audit/): Free product-page CRO audit. Paste a store domain or product URL (https:// optional); homepages resolve to a best-selling product. Reads the product page and cart like a shopper, no admin login, scores against a product-page rubric, ranks what stops the sale and what keeps the basket small, and returns a shareable report, badge and PDF. Password-protected stores work. Not a conversion-rate prediction.
- [ChatGPT SEO check for Shopify stores](https://ninety9.dev/chatgpt-seo/): Free check of whether ChatGPT and other AI assistants can read a Shopify page. Reads public JSON-LD structured data, indexability, robots.txt rules for AI crawlers and llms.txt. Not a citation rank. Buttons open ChatGPT, Claude, Gemini or Perplexity with a short prompt about the page.

## Quick answers

- **How do I increase average order value on a Shopify store?** Add one offer at each high-intent moment: a bundle or quantity break on the product page, an upsell and a free-shipping goal in the cart, a single targeted popup at add-to-cart or exit, and a post-purchase offer after payment. Start with the moment where your funnel leaks most, measure for two weeks, then add the next.
- **Which Ninety9 app should I install first?** If shoppers buy one item at a time, start with Addly for bundles and quantity breaks on the product page. If carts are abandoned or small, start with Addy (AI cart drawer) and Goalify (free shipping progress bar). If you want one well-timed offer without touching the theme, start with Monet. If support is drowning in order changes, start with Reviso.
- **Do the Ninety9 apps work together?** Yes. Each app owns a different moment in the buying journey — product page, cart, checkout intent and post-purchase — so they stack without showing duplicate offers. You can install one and get the full benefit, then add another later.
- **Are Ninety9 Shopify apps free?** Every app has a free plan or is free to install. Where paid tiers exist they are billed through Shopify, start from a few dollars a month, and step up with your store’s monthly order volume.
- **Will these apps slow down my Shopify store?** No. Each app is a Shopify theme app extension: it loads asynchronously, stays out of the Largest Contentful Paint path, makes no edits to theme.liquid and uninstalls cleanly. You enable it from Online Store → Themes → Customize → App embeds.
- **Do I need a developer to set up upsells or a cart drawer on Shopify?** No. Install from the Shopify App Store, switch the app embed on in the theme editor and configure offers in the app. Most merchants are live in under ten minutes, and support replies from a developer, not a script.
- **How do I find out what is wrong with my Shopify product page?** Run the free CRO Audit for Shopify stores (https://ninety9.dev/cro-audit/). Paste your store or product URL and it checks the product page and cart the way a shopper sees them, ranks what stops the sale, and names the fix. No login and no card required.
