Conversion Rate (CVR)

What is CVR?

Conversion rate, commonly abbreviated CVR, measures the share of clicks (or another input action) that turn into the outcome a campaign is actually built around, a purchase, a lead, a sign-up, whichever action matters for that objective. Meta does not ship a single column named Conversion Rate inside Ads Manager the way it ships Impressions or CPM. Instead, Meta's own Business Help Center documents Custom Metrics, a feature that lets an advertiser formulate and save their own custom metrics from the Ads Manager table and Ads Reporting. Meta's help article does not name conversion rate directly, but the same mechanism covers it: divide a result, such as purchases or leads, by link clicks or landing page views, then format it as a percentage and save it for reuse. Meta's Marketing API reflects a similar gap. The public Ads Insights field reference does not expose one generic conversion_rate field; the closest named fields are conversion_lead_rate, scoped specifically to lead generation, and result_rate and objective_result_rate, which generalize a results-based rate across whichever objective a campaign is optimizing toward. A related but different Meta metric, conversion rate ranking, shows up as one of the three ad relevance diagnostics: it compares your ad's expected conversion rate to other ads chasing the same optimization goal and audience, reported as a percentile band like above average rather than a raw percentage, so it answers a different question than your own CVR does. Outside Meta, conversion rate is one of the most universal ad metrics across every platform, and third-party industry reports remain the most common source of a benchmark figure, since Meta itself does not publish one.

1. 1

   Build conversion rate as a Custom Metric in Ads Manager instead of hunting for a built-in column. Meta's own Custom Metrics feature lets you divide any result, purchases, leads, registrations, by clicks or landing page views and save the formula for every future report.

2. 2

   Match the denominator to what you are actually measuring. Dividing by link clicks answers how well the landing page converted people who clicked, while dividing by landing page views filters out clicks that never finished loading a page, and the two will not produce the same percentage.

3. 3

   Do not confuse your conversion rate with Meta's conversion rate ranking. Ranking is a relative ad relevance diagnostic that compares your ad against others competing for the same audience and optimization goal, while your own CVR is a plain ratio of results to clicks and can be high even when your ranking sits at average.

4. 4

   Segment conversion rate by placement and device before optimizing creative. A campaign-level CVR can hide a landing page that converts well on desktop and poorly on mobile, and Meta's breakdown view exposes that split without needing a new campaign.

5. 5

   Treat third-party conversion rate benchmarks as a rough compass, not a target. WordStream's own report is scoped to leads-objective campaigns and swings from under 4% to over 18% by industry, so compare your CVR against your own history and objective, not a single industry average.
