Search Console comparison tool
Compare two Search Console periods
Upload your Search Console exports for both periods, set the period lengths, then run the analysis. Everything happens in your browser — nothing is uploaded to a server.
How it works
RankingDiff's workflow is a straight line: you upload before data, you upload after data, RankingDiff runs the analysis, and you get back the observed patterns. Specifically, you export the Queries and Pages tabs from Search Console's Performance report for each period — four CSV files in total — plus how many days each period covers:
- 01 · Before — Queries
- Search Console → Performance → Queries tab, exported as CSV, for the earlier period.
- 02 · Before — Pages
- Search Console → Performance → Pages tab, exported as CSV, for the same earlier period.
- 03 · After — Queries
- The same Queries export for the later period you're comparing against.
- 04 · After — Pages
- The same Pages export for the later period you're comparing against.
Period lengths don't need to match — RankingDiff normalizes clicks and impressions to daily rates automatically, so a 7-day period can be compared against a 28-day period without distorting the result.
Fix the following before running the analysis:
Upload the earlier export
Performance → Queries tab → Export → CSV
No file selected
Performance → Pages tab → Export → CSV
No file selected
Upload the later export
Same Queries export for the later period
No file selected
Same Pages export for the later period
No file selected
How many days does each export cover? They don't need to match — RankingDiff normalizes clicks and impressions to daily rates automatically.
Runs entirely in your browser. No data is uploaded.
Your uploaded files are parsed and analyzed in this browser tab only. They are not uploaded to a server, stored in a database, or sent to any third party — there is no account and no Search Console API connection.
What this tool does
RankingDiff is a Google Search Console comparison tool: it takes two periods of your own Search Console export and shows you exactly what changed between them. It's not a rank tracker and not a general SEO audit tool — it only compares the data you give it.
What it analyzes
- Clicks, impressions, CTR, and impression-weighted position for both periods
- Which queries and pages are new, lost, or retained across the two periods
- How the retained cohort of queries and pages moved specifically
- How concentrated any loss is across pages and queries
- Whether gross gains and gross losses are offsetting each other
- Whether aggregate metrics and entity-level metrics agree or contradict
What makes it different
- Deterministic — the same input always produces the same output; no model is making a judgment call
- Evidence-based — every pattern it reports comes with the specific numbers behind it
- Client-side — your CSV files are parsed and analyzed in your browser; nothing is uploaded to a server
- Honest about its limits — it identifies measurable patterns in your data; it does not claim to know why Google's traffic changed
