What KPIs Should You Track to Identify Conversion Drops?

KPIs to Check First

Conversion rate is the headline metric, but it should not be read alone. A drop in orders can come from fewer clicks, weaker click quality, or a listing page issue. Tracking the following indicators together helps narrow the cause before you make changes.

• Conversion rate: Orders divided by clicks. A sustained decline usually means traffic is less relevant or the listing is underperforming.
• Ad CTR: Clicks divided by impressions. A falling CTR often points to ad creative, placement, or keyword relevance issues.
• ACOS: Ad spend divided by ad revenue. Rising ACOS can show that spend is growing faster than returns.
• ROAS: Ad revenue divided by ad spend. Lower ROAS signals weaker return from the same or higher spend.
• Wasted spend: Clicks that do not convert. Monitoring this helps you spot terms that consistently eat budget without orders.

How to Read the Patterns

Isolated daily changes can be noise, especially during short promotions or stock changes. What usually matters is a pattern across several days or weeks. Compare the current period with the same length of time before the drop, and look for outliers that repeat.

An Amazon Ads Dashboard by Todoza is built for this type of trend review. It consolidates ad reports and tracks core metrics including spend, sales, ROAS, and wasted spend, so sellers can spot declining campaigns without manually stitching together spreadsheets.

When This Matters

This type of KPI review is most useful when a campaign has been running long enough to have a reliable baseline. It matters even more for sellers managing multiple campaigns, marketplaces, or accounts, where a single underperforming keyword can quietly raise overall ACOS. If you suspect wasted spend is part of the problem, a tool like Amazon Negative Keyword Tool by Todoza can help classify search terms into negative keyword candidates, bid-reduction opportunities, or terms that need more data.
