Every website leaves a trail of URLs in the Wayback Machine — every page ever published, every blog post ever written, every product page ever created. Even pages that have since been deleted still exist in the archive, along with their full URL paths. Knowing how to extract and use this URL data is one of the most powerful techniques available to SEO professionals. This guide covers exactly how to extract all URLs from any website using the Wayback Machine, and what to do with that data once you have it.

Why Extract URLs from the Wayback Machine?

There are four main scenarios where a complete URL extraction is invaluable:

  • Site recovery — you need a full inventory of every page that existed before a crash or migration
  • Competitor research — you want to see every page a competitor has ever published, including deleted ones
  • Link building — you are looking for deleted pages with existing backlinks to target for link reclamation
  • Content audits — you want to understand the full scope of a site's content history before taking on an SEO project

The Manual Method (and Why It Is Slow)

The Wayback Machine's web interface at archive.org allows you to browse a site's history page by page. You can click through snapshots and see individual pages, but there is no built-in way to export a complete list of all URLs. To do this manually, you would need to crawl through the site's sitemap in each archived snapshot, click through every page, and record each URL — a process that could take hours or days for a large site.

The Fast Method — Using the CDX API

The Internet Archive provides a CDX (Capture Index) API that lets you programmatically query their database for all URLs ever crawled for a specific domain. A properly formatted API call returns a plain text list of every URL, along with the date it was first and last captured, the HTTP status code, and the MIME type. This is the same data source that powers dedicated URL extraction tools.

The Fastest Method — Our Wayback URL Extractor

Our free Wayback URL Extractor handles all the API complexity for you. Simply enter a domain name and within seconds you get a complete, deduplicated list of every URL ever archived for that domain. You can filter by file type, date range, and HTTP status, then download the full list as a CSV for use in Excel, Google Sheets, or any SEO tool.

For large sites with thousands of archived URLs, the tool handles pagination automatically — no need to make multiple API calls or stitch together partial results.

What to Do with Your URL List

Once you have a complete URL inventory, here is how to put it to work:

1. Cross-Reference Against Live Site

Export your archived URL list and compare it against your current sitemap or a fresh crawl of your live site. Any URL that appears in the archive but not in the current crawl is either deleted, redirected, or returning an error. Categorise these into:

  • Pages that should be redirected but are not
  • Pages with existing backlinks that should be recovered
  • Pages that were correctly removed and need no action

2. Find Your Missing Redirects

After a site migration, redirect chains and missing redirects are the most common cause of ranking loss. Your archived URL list tells you exactly which old URLs existed — run each through a redirect checker to confirm they are properly redirecting to the correct new URLs. Any that return a 404 should be redirected immediately. Use our Broken Link Checker to identify which of these broken URLs still have external links pointing to them — those are your highest priority redirects.

3. Build Your Link Reclamation List

Filter your URL list for pages that are now deleted (404) and check each one for backlinks using your preferred backlink tool. Any deleted page with one or more backlinks is a link reclamation opportunity. Create new content on the same topic and either redirect the old URL to the new page, or reach out to the linking sites with your replacement content.

4. Analyse URL Structure Patterns

A complete URL inventory reveals the full architecture of a site — how content was categorised, how deep the navigation went, which sections were most heavily developed. For competitor research, this tells you exactly where they invested content effort. For your own site, it helps you spot structural inconsistencies and orphaned page clusters that are not receiving enough internal link support.

5. Identify Niche Topic Clusters

Look at URL paths and slugs to identify topic clusters. If a competitor has 40 URLs containing the word backlinks in the path, that is a significant content investment in that topic. Compare this against current rankings to assess whether the investment paid off — if they rank well for backlink-related queries, that cluster strategy is worth studying and potentially replicating.

Filtering Your URL List

Raw URL lists from large sites can contain tens of thousands of entries, many of which are irrelevant — paginated archive pages, tag pages, filter URLs, and duplicate parameter variants. Our Wayback URL Extractor includes filtering options to exclude common URL patterns, helping you focus on the content pages that matter for your research.

Summary

Extracting all URLs from a website's Wayback Machine history is one of the highest-leverage SEO research techniques available. It gives you a complete picture of any site's content history — including pages that no longer exist — and opens up opportunities for link reclamation, competitor analysis, migration auditing, and content gap discovery. Use our free Wayback URL Extractor to get started, and combine your URL inventory with our Broken Link Checker to identify which archived pages are most urgently in need of attention.
