## How to choose

- You want to follow a few direct competitors closely (store, ads, emails): **TrendTrack**, whose Starter plan tracks 2 brands and Pro 10.
- You're mainly looking for Meta ads and products to test: **Minea** or **TrendTrack**.
- You just want to look at a store from time to time, for free: **Koala Inspector**.

Whatever the tool, traffic and sales figures are estimates. Use them to compare stores with each other, not as real revenue.

## FAQ

**Is it legal to spy on a Shopify store?**

These tools analyze public information: ads that are running, store pages, emails received after signing up. Copying protected visuals or copy, however, is still prohibited.

**Are sales and traffic estimates reliable?**

They are estimates, and vendors present them as such. Use them to compare stores with each other, not to know exact revenue.

**Which free tool can analyze a Shopify store?**

Koala Inspector has a free plan that never expires and shows a store's theme, apps and products. TrendTrack also offers a free Chrome extension.
