Benchmark
A benchmark is a reference point used to compare performance.
It helps give a measurement context beyond its standalone value.
Common Types of Benchmarks
A website might compare results against:
- Its own previous performance
- A defined target
- A previous period
- Similar page types
- Industry data
- Comparable organizations
- A control group
- A baseline measured before a change
Not all benchmarks are equally useful.
Internal vs. External Benchmarks
An internal benchmark compares performance against the same organization's historical or parallel data.
For example:
This year's enquiry rate compared with last year's.
An external benchmark compares performance against outside organizations or industry datasets.
Internal comparisons are often easier to interpret because more of the context is known.
Why It Matters
A number without comparison can be difficult to evaluate.
For example:
Conversion rate is 3.8%.
Is that good?
The answer depends on:
- What counts as a conversion
- The audience
- The type of website
- The traffic source
- The period being measured
- The organization
- What the previous result was
Benchmarks provide some of that context.
Common Problems
Common benchmarking problems include:
- Comparing unlike businesses
- Using industry averages with unclear methodology
- Ignoring sample size
- Treating averages as targets
- Comparing differently defined metrics
- Failing to account for seasonality
- Using a previous period that was itself unusual
- Chasing competitor numbers without understanding their goals
How to Improve
Prefer benchmarks that are relevant and explainable.
For many organizations, comparing against their own historical baseline is more useful than comparing against a broad industry average.
Document the comparison period and metric definition so the benchmark remains meaningful over time.
Benchmarks can also help interpret Website Performance and Core Web Vitals when comparing templates or changes over time.
