FAQ
What URL metadata does this tool need?
A CSV with columns: url, canonical, noindex (yes/no), robots_blocked (yes/no), status_code. The canonical column can be empty (counts as missing canonical). Header row is optional and auto-detected. Each row is parsed and validated independently — malformed rows are reported as errors.
How are URLs classified?
Six outcomes: (1) indexable — no noindex, not robots-blocked, status 200, self-canonical. (2) canonicalized — canonical points to a different URL (still indexed, but signals consolidate). (3) noindex — has noindex directive. (4) robots_blocked — blocked by robots.txt. (5) error_status — status code not 2xx. (6) duplicate_canonical — multiple URLs canonicalized to the same target.
Does this detect canonical chains and duplicates?
Yes. Canonical chains (A→B, B→C) are detected by walking canonical pointers. Duplicate canonicals surface when two or more URLs canonicalize to the same target — these can waste crawl budget and should be reviewed. Missing canonicals (empty canonical field) are also flagged.
What extra features does this tool have compared to others?
(1) CSV parser with header auto-detection and field validation. (2) Six-way URL classification. (3) Canonical chain detection (A→B→C). (4) Duplicate canonical finder (multiple URLs → same target). (5) Missing canonical detector. (6) Self-canonical vs non-self-canonical counter. (7) Indexable URL list. (8) Blocked URL list (noindex + robots). (9) Text report rendering. (10) CSV export (url, classification, canonical_target). (11) Copy + Download .txt + Download CSV. (12) History (localStorage, last 20). (13) Shareable URL (encodes records in hash). (14) Filter by classification. (15) Summary stats (% indexable, % blocked). (16) Recommendation generator (e.g. 'Add canonical to URL X').
Is my data sent anywhere?
No. CSV parsing and classification happen entirely in your browser. History is stored in localStorage on this device only. URL metadata never leaves the page.
