Key KPIs for monitoring campaign success

Tracking organic traffic shows how well your site attracts visitors without paid ads, reflecting your brand’s pull in search results. Dive deeper with Lenny’s newsletter on content-driven growth.

Click-through rate (CTR) and cost-per-click (CPC) measure how well your ads capture attention and if your budget is effective. A high CTR means your message resonates; a low CPC means you’re spending wisely. Both metrics are vital for understanding your reach and efficiency.

Conversion rate indicates if visitors are taking action—whether signing up, buying, or subscribing. Pair this with return on ad spend (ROAS) to see if your investment is worthwhile. For more on selecting impactful metrics, see experimenting with KPIs and metrics.
