Compare two Search Console Pages CSV exports, find declining-page candidates and export a content review list. No Google login or upload required.

Your input stays in this tab

Files and pasted content are processed locally, never uploaded or saved. Closing or refreshing clears them. Usage events contain the tool name and action only.

How to use this tool

1.In Search Console, select the Pages table for a defined date range and export it as CSV. Repeat for a later, nonoverlapping period using the same filters.
2.Enter both inclusive date ranges and confirm filter consistency. Use equal-length periods or enable per-day normalization.
3.Review declining pages, missing export rows and directory changes. Add your investigation notes before exporting; the report does not diagnose the cause of a decline.

Prior Pages CSV

Required English headings: Page (or Top pages), Clicks, Impressions, Position. One row per page; dot decimals and comma thousands supported.

Or choose a local file

Current Pages CSV

Use a separate Pages export with the same property and filters. Missing rows will remain unknown, not zero.

Or choose a local file

Prior period start

Prior period end

Current period start

Current period end

Minimum impressions in either export

Normalize click counts per day (allows unequal windows)

Both exports have the same property, country, device, search type and query/page filters

Comparison context (optional)

Record seasonal differences, site changes or limitations. This stays local and appears in the report.

This compares supplied rows, which may be incomplete. CTR is recomputed; position is an average. Seasonality, changing query mix and SERP changes need human review. Maximum 2 MB and 20,000 rows per export.

Keep the evidence with your decisions

The result tables preserve the observations behind each finding. Filter rows to focus your review, add notes to the main table and export a CSV. Use the text report to keep the method and limitations alongside the data.

A local diagnostic answers a bounded question about the input you provide. It does not prove how a search engine crawled, indexed or ranked your site. Follow up with a live check or the relevant first-party report when the decision depends on that evidence.

FAQ

Does RankCrab upload or store my files?+

No. The tool processes the input in this browser tab. It does not upload, save or fetch the supplied URLs. Closing or refreshing clears your input. Basic tool-name/action events never include file contents, filenames, URLs or queries.

Can I try it without preparing a file?+

Yes. Load the worked example and run the check to see a clearly fictional input and its output. Replace the sample with your own data before making decisions.

What are the limits of this check?+

Can I export the result without signing up?+

Yes. Download every result table as CSV or save a text report with method notes. Reviewer notes appear in the corresponding table CSV. Exports escape formula-like cell values for safer spreadsheet use.
