Match both export scopes
Keep property, search type, country, device, filters, dimension, and date length consistent. Otherwise the comparison mixes scope changes with performance changes.
Search Console history · supplied export evidence
Compare query or page performance between two Search Console exports
Import matching baseline and current CSV or TSV files. OpenWebmaster accounts for every retained row, compares clicks, impressions, CTR, and average position, and exports the complete matrix without estimating search volume, traffic, rankings, or causes.

Ready for two real Search Console exports.
No sample decline, content-decay claim, rank trend, traffic estimate, or manufactured performance metric appears before you supply evidence.
Performance review workflow
Use the delta as a question, not a diagnosis
Check the surrounding evidence
Review seasonality, release notes, page edits, crawl/index state, SERP features, query intent, and analytics outcomes before describing a decline.
Record the intervention
Save the complete export and annotate what changed. Compare another equivalent period after enough observation time without claiming causation from adjacency alone.
