How SEOPlan measures your website

Methodology revision: September 21, 2026. These are implementation limits, not a promise of rankings, traffic, revenue, or Google indexing.

One fetched page, not a whole-site certificate

The page audit inspects the fetched HTML and available response evidence for the submitted URL. It does not establish that every page on your domain works. Content inserted only after JavaScript runs may not be represented. A high score does not mean your content meets every visitor’s need or that your site is legally compliant, secure, accessible, or indexed.

How the page score is calculated

Each included check has a weight. A pass earns its full weight, a warning earns half, and a failure earns zero. The score is the rounded percentage of earned weight divided by total included weight. It is not a percentile or an industry benchmark.

score = round(100 × sum(weight × result) / sum(weight))
result: pass = 1; warning = 0.5; failure = 0

For example, three illustrative checks weighted 10, 8, and 6 with pass, warning, and failure earn 14 of 24 points: 58/100. This miniature example is not an actual customer score.

Current HTML-check weights

Presence checks are not quality guarantees

• Title and description lengths are heuristics, not Google’s fixed limits. A warning can be reasonable for a particular page.
• A detected canonical does not confirm that its destination is suitable or that Google selected it.
• The HTML indexing check does not replace a full review of robots.txt, HTTP headers, access restrictions, and Google’s own indexing decision. Use the Indexability Checker for additional technical evidence.
• An internal-link count does not test every destination. An alt attribute can exist without describing an image well.
• Valid JSON is not the same as eligibility for a Google rich result. Word count is not a content-quality measure.
• Optional performance or enrichment results have their own source and scope; do not treat them as a live user-experience measurement of every visit.

Missing evidence is not zero

A measured zero is different from an unavailable metric, an unconnected property, a provider error, or an expired report. Do not infer zero demand or zero traffic from a blank result. Google data depends on the selected property, permissions, date range, and data availability. Keyword volumes, difficulty, and observed rankings are provider estimates, not guaranteed live rankings or forecasts.

Freshness and repeat checks

Use the date on each result. Saved audit reports expire after 30 days; a saved report is not a new scan. Matching market reports can be reused for seven days, and Google evidence is cached for up to six hours. A fresh request may use your allowance. Changes after the original scan require fresh evidence, not just a refreshed display of the old report.

What Fix Verification establishes

For supported selected findings, Fix Verification compares owned, unexpired audit evidence for the same submitted page and requires a newer completed audit after the task was marked done. Missing or mismatched evidence requires review. Passing those selected checks does not establish that all issues are resolved or that Google has recrawled, indexed, or ranked the page. Manual checks remain necessary where a guide says so.

AI recommendations need human review

AI suggestions interpret the supplied evidence and can be incomplete or incorrect. Review proposed wording, facts, schema, and technical changes before publishing. SEOPlan does not silently apply fixes to your website. Check original evidence and business relevance before prioritizing an AI recommendation.
