Lennon Tree Index

Generate up-to-date XML sitemaps in minutes.

Get a Free Account Now

Index is a free XML sitemap generator. Add a domain and it crawls your site and builds your sitemap in minutes, covering your pages, images and videos in one pass. Download it in the format you need, or submit it straight to the search engines, and run it again whenever you want a fresh one.

The problem it solves

A sitemap is only useful while it's accurate. You add pages, move pages, retire pages, and the sitemap you generated months ago drifts out of date. Index lets you build a fresh, current one in minutes, whenever you need it. And if you'd rather it looked after itself, Connect Pro keeps it updating automatically.

How it works

Add your domain

Point Index at a site you've claimed. It crawls the site and finds your pages, images and videos.

Index builds your sitemap

You get a full XML sitemap with the detail search engines want: last modified date, priority and change frequency for every URL.

Download or submit

Take your sitemap as XML, GZ, CSV or HTML, grab the RSS feed and image sitemap alongside it, then submit it to the search engines. When your site changes, run it again and you have a current sitemap in minutes.

What you get

  • A complete XML sitemap, built in minutes and updated whenever you run it.
  • Coverage for pages, images and videos in a single crawl.
  • Multiple outputs: XML, GZ, CSV and HTML, plus an RSS feed and a dedicated image sitemap.
  • Per-URL detail: last modified date, priority and change frequency.
  • Coverage diagnostics: what was discovered, what redirected, and what was skipped, so nothing important goes missing.

Want your sitemap to refresh itself on a schedule, without you lifting a finger? That comes with Connect Pro.

Pricing

Index is free. The free generator updates manually: you run it whenever you want a current sitemap, and it builds in minutes. If you want it to update automatically on a schedule, that comes with Connect Pro.

Where Index came from

Index was built in-house, the same way as the rest of the suite: a job that needed doing properly, done by the people who needed it doing. The full story is in Field Notes.

Common Questions

What is an XML sitemap?
An XML sitemap is a file that lists the important URLs on your site, along with detail like when each page last changed and how often it updates. It helps search engines find and understand your pages.
What does Lennon Tree Index do?
You give it a domain, and it crawls the site and builds a complete XML sitemap covering your pages, images and videos. You run it again whenever you want to refresh it.
Is Index free?
Yes. The free generator updates manually. Automatic, scheduled updating comes with Connect Pro.
What formats does Index give me?
Your sitemap comes as XML, GZ, CSV and HTML, with an RSS feed and a separate image sitemap alongside it.
Does Lennon Tree Index cover images and videos?
Yes. A single crawl covers pages, images and videos, with reference counts and coverage detail for each.
How do I get my sitemap to Google?
Download it from Index, or submit it to the search engines yourself. When your site changes, regenerate it and resubmit, or let Connect Pro keep it updating automatically.
Does my sitemap stay up to date?
The free generator updates manually, so you refresh it yourself whenever your site changes, and it rebuilds in minutes. If you want it kept current automatically on a schedule, that is part of Connect Pro.
