Indexation Rate Calculator

Measure what share of submitted URLs are actually indexed.

About Indexation Rate Calculator

The indexation rate is the share of urls submitted in the sitemap that urls indexed represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

Formula

Indexation Rate

Indexation Rate = URLs indexed ÷ URLs submitted in the sitemap × 100

URLs indexed
The subset being measured
URLs submitted in the sitemap
The full population it is drawn from

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Indexation Rate calculated?

Indexation Rate = URLs indexed ÷ URLs submitted in the sitemap × 100 The indexation rate is the share of urls submitted in the sitemap that urls indexed represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small.

Why does Indexation Rate matter?

Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

What values do I need to enter?

This calculator takes 2 inputs: URLs indexed, URLs submitted in the sitemap. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
