# Spot problems early.

Catch broken codes, tired ads and slow pages before they waste paid traffic.

## About this section

Most wasted ad spend is not a bad strategy. It is something that quietly broke: a discount code that fails at checkout, an ad that people have now seen too many times, a page that loads slowly on a phone. Each one sends paid traffic somewhere it cannot convert, while the ad platform carries on reporting as usual.

This section is for ecommerce owners and marketing managers who do not have time to check every campaign and page each day. The guides cover broken discount codes on Shopify, creative fatigue in Meta ads, checkout friction and site speed. For each one they explain how to recognise the problem, a simple test you can run yourself, and what to put in place so you hear about it before your customers do. The aim is a short routine rather than a bigger dashboard: know what normal looks like, notice when it changes, and fix the cause.
