Files processed in-browser — public URLs checked before merging
See exactly where your URLs cannibalize each other — in plain English.
Drop in a GSC export (CSV or XLSX). We group competing pages, quantify the click split, flag unstable rankings — and tell you whether to consolidate, canonicalise, or differentiate.

Step 1
Create the dataset you'll use for cannibalization analysis
Search Console alone won't show you cannibalization
Search Console shows queries and pages in separate lists, capped at ~1,000 rows — so you never see which page took which query. That pairing is exactly what cannibalization analysis needs.
Our ready-made Looker Studio report pulls the Query + Landing Page pair straight from the Search Console API — up to 750,000 rows. Export as CSV, drop it in here, done.
Query + URL paired
Every keyword sits next to the exact landing page that ranked for it — the pairing the Search Console UI hides.
Up to 750,000 rows
Pulled through the API instead of the ~1,000-row UI export, so long-tail overlap isn't cut off.
Full metric set
Impressions, URL clicks, CTR and average position per pair — everything the clustering engine scores on.
Yup... we know we could add Search Console straight away, but... we are too lazy to be a verified developer. So for now... workaround.

All features
Your data, ready for analysis
- Search Console / Looker Studio CSV and XLSX imports, plus support for Semrush exports.
- Looker Studio template, downloadable example exports and a sample analysis to try before using your own data.
- File and column validation, helpful import errors, and progress with elapsed time and estimated time remaining for large files.
- Files and metrics are processed in your browser. Public URL addresses are sent for HTTP trailing-slash verification before merging; files and keyword metrics are not uploaded.
- Data verification with before-and-after URL counts, asset exclusion and URL-normalization details.
Cannibalization, from every angle
- Summary dashboard with competing pages, click splits, impressions, CTR and average positions.
- By Query and By URL views with expandable keyword–page breakdowns, overall URL traffic and cluster details.
- Impressions-based or position-based cannibalization analysis, with focus presets for strongest overlap, biggest click split and unstable rankings.
- Head-to-head URL comparison with two URL searches, keyword selection and expandable keyword results.
- Keyword-to-URL matching: rank candidate URLs, compare the top three and include impressions from your uploaded data.
- Safe queries view and plain-language recommendations for consolidation, canonicalization or differentiation, with confidence and tradeoffs.
Cluster strategy & internal linking
- Four strategy sections: primary articles, consolidation candidates, potentially noindex candidates and internal-linking targets.
- Path-based contains and exclusion filters, with OR / AND matching and one strategy role per URL.
- Primary article and anchor selection, consolidation pairs with a clear 301 direction, and explanations of why each action is suggested.
- Internal-linking checklist and copyable WordPress ‘Read also’ HTML blocks, using page summaries and readable anchors.
- Published-date checks to protect recent articles, plus checks for existing ‘Read also’ headings.
- Safeguards against self-links, conflicting anchors, duplicate consolidation and negative recommendations for the homepage.
Content opportunities & zero-click review
- Missing content candidates with clicks, impressions, targeted pages, opportunity scoring and adjustable uniqueness thresholds.
- Question, geographic, language and brand filters, with similar ‘cousin’ keywords grouped or excluded.
- Prompts searcher for long queries with zero clicks: adjustable word count, impressions, similarity, question and punctuation filters.
- Cleanse review for negligible URLs and clusters, with adjustable thresholds and cautious ‘Potentially noindex’ explanations.
- All zero-click URLs in one view, with reversible exclusion from analysis and a before-and-after noise comparison.
- Crawl / Stop Crawl checks exposing original HTTP status, technical indexability, X-Robots-Tag, robots.txt and robots meta restrictions. These checks contact public URLs; they do not confirm Google indexing.
A workspace you can tailor
- Date-range filtering when dates are available, minimum-impression thresholds, query / URL search and URL autocomplete.
- Clickable URL-path unigrams and hyphenated two-word groups to narrow results or fill the URL comparison.
- Optional query-string URL folding, fragment normalization and language exclusion, with explanations of how totals are combined.
- Sortable tables, resizable columns, density settings, expandable rows and metric tooltips.
- Named filter / sort presets and URL bookmarks saved in your browser, with bookmarked-only reporting.
- English and Polish, light / dark themes, extra contrast enabled by default, visible keyboard focus, and a New Analysis reset.
Reports that turn findings into actions
- Create Report with a preview and PDF, Word and spreadsheet options, plus CSV exports for supported views.
