Five GEO performance metricsCalculation rules and SUMMITFEED audit results

By SUMMITFEEDPublished 2026-06-23Updated 2026-08-23

This guide explains what AI Visibility, Citation Rate, Share of Voice, Mention Volume, and Platform Coverage count and which conditions must accompany each result.

QUICK ANSWER

Read all five metrics together

The five metrics measure appearance, evidence, competitive share, absolute volume, and platform range. Even identically named metrics produce different figures when valid-response rules or units of analysis differ. The goal is to overlap metrics and find the bottleneck—not react to one metric in isolation.

These figures are technical validation results for public URLs, canonical tags, and JSON-LD—not AI Visibility. They are kept separate from AI response metrics and indicate whether the site's measurable foundation is healthy.

5 METRICS

The five metrics at a glance

01 · Appearance

AI Visibility

Visibility rate

Appearance

Valid responses mentioning the brand ÷ all valid responses × 100

Does our brand appear in the answer?

Check: Separate branded and non-branded questions.

02 · Evidence

Citation Rate

Official-source citation rate

Evidence

Valid responses linking an official URL ÷ all valid responses × 100

Is our document used as evidence?

Check: Verify both the citation URL and whether the link resolves.

03 · Share

Share of Voice

Mention share

Share

Brand mentions ÷ mentions of all comparison brands × 100

How much share do we hold against competitors?

Check: Fix the comparison-brand list and duplicate-mention rule.

04 · Volume

Mention Volume

Absolute mention volume

Volume

Total brand mentions observed during the measurement period

How often did the brand appear within the measurement scope?

Check: Record question count, platform count, and repeat count.

05 · Range

Platform Coverage

Platform coverage

Range

Platforms where the brand appeared ÷ all measured platforms × 100

Is visibility distributed across platforms?

Check: Read it together with AI Visibility for each platform.

Overlapping metrics explain the cause

One value only shows movement. Two metrics together reveal which layer is blocked and which task to check first.

Observed combinationWhat it suggestsCheck first
High Visibility · low CitationThe name is known, but official documents are not used as evidenceIndexed pages with definitions, figures, procedures, and comparison tables
High Citation · low VisibilityDocuments are used, but the brand connection is weakPublisher, author, and company-name presentation

What belongs in a monthly report?

A report should support the same measurement next month. Record calculation conditions and supporting data beside each value.

REPORT RULE

Do not collapse the metrics into one score

The five metrics use different measurement rules. Put changed and unchanged metrics side by side to reveal the next task.

  • Question-set version and change history
  • Platform list and model versions
  • Country, language, and login state
  • Repeat count and measurement cycle
  • Valid-response rules and unit of analysis
  • Brand-name variants and comparison-brand list
  • Storage location for full responses, citation URLs, and collection time

Frequently asked questions

What are the five GEO performance metrics?

AI Visibility, Citation Rate, Share of Voice, Mention Volume, and Platform Coverage. They measure appearance, evidence, competitive share, absolute volume, and platform range.

How do AI Visibility and Citation Rate differ?

AI Visibility counts whether the brand name appears. Citation Rate counts whether an official URL is connected as a source. A named brand and an official document used as evidence are different outcomes.

How many questions should a GEO measurement use?

Start by checking how many percentage points one response can move the total. Repeat the same questions under the same conditions to measure run-to-run variance, then expand the question and platform set.

Can Share of Voice be used directly as a KPI?

First inspect the calculation. Period comparisons require the comparison-brand list, duplicate-mention rule, and whether the number is observed or modeled.

What should I check if metrics rise but inquiries do not?

Start with the cited URLs and the next-action path on those pages. An old article or a page with no inquiry path can be cited repeatedly without creating business action.

Are SUMMITFEED's published figures AI Visibility results?

No. The 82/82 and 166/166 figures on this page are technical website-audit results. They are separated from AI response metrics and show whether the site's measurable technical foundation is operating correctly.

CONCLUSION

Read the calculation rules before the number

Define valid responses and the unit of analysis first, then overlap appearance, evidence, and competitive share. SUMMITFEED separates technical audit results from AI response metrics and stores questions, platforms, timestamps, and full responses to decide the next reinforcement task.
