Audit Comparison

Audit Comparison lets you view two audits for the same URL side-by-side to see exactly what changed — scores, metrics, recommendations, and content signals — between two points in time.

Opening Comparison

There are two ways to open Audit Comparison:

From the Trends chart: Click the comparison icon (two overlapping squares) in the chart toolbar, then click two data points on the chart to select the audits to compare.

From the Audits list: Check two audits in the list view and click Compare Selected in the toolbar that appears at the bottom of the page.

The comparison view

The comparison view shows the two selected audits side-by-side. The left panel is the baseline (earlier audit) and the right panel is the comparison (later audit).

Score summary strip

At the top, the overall score and six category scores are shown for both audits with a delta badge:

• Green delta (↑ N) — score improved
• Red delta (↓ N) — score declined
• Gray delta (= 0) — no change

Click any category score to jump to that category's detailed comparison.

Metric-level diff

Each category section shows a table of metrics with:

Column	Baseline audit	Comparison audit
Metric	Value	Value
Rating	Good/Needs improvement/Poor	Good/Needs improvement/Poor
Delta	—	↑/↓/=

Metrics that changed rating (e.g. from Good to Needs improvement) are highlighted with an amber border.

Recommendation diff

The Recommendations section shows:

• Resolved — recommendations that existed in the baseline but are gone in the comparison (score improved in that area)
• New — recommendations that are new in the comparison (something regressed)
• Unchanged — recommendations present in both

Content diff

For title, meta_description, heading_h1, and structured_data fields, the comparison shows an inline diff of the raw values — what the page contained in the baseline vs. what it contains now.

Selecting which audits to compare

You can compare any two audits for the same URL, not just consecutive ones. For example, compare a baseline from 90 days ago with today's audit to measure the total impact of an optimization sprint.

If the two audits are for different URLs, the comparison is disabled. Use a project with consistent URL auditing (or Sitemap audits) to build a history of the same URL over time.

Exporting the comparison

Click Export to download the comparison as a PDF report. The PDF includes the score summary, metric diff table, and any new or resolved recommendations. This is useful for client reporting or post-deployment reviews.
