SEO Tools

Free SEO utilities: stem and count keywords, analyze XML sitemaps, encode and decode URLs in bulk, and build UTM codes and URL parameters at scale.

Percent-encode or decode a whole list of URLs at once — paste, pick a direction, done.

Open a whole list of URLs at once, right from your browser — no extension required.

Add or overwrite any query parameter across a whole URL list in one pass — existing query strings are preserved.

Tag dozens of URLs with consistent UTM parameters in one pass — existing query strings are preserved.

Skip hand-writing BigQuery SQL for GSC bulk-export data — paste the report URL you're already looking at and get a query that matches it.

Cluster and match keywords by their word stem in one paste — no server round-trip.

See word frequency and keyword density at a glance — nothing leaves your browser.

Get a fast structural read on any XML sitemap — URL counts, path breakdown, and freshness — without downloading and parsing it yourself.
