What it is.
You point the SEO Spider at your domain and let it crawl. When it finishes, the Response Codes tab filtered to Client Error shows every URL that returned a 404 not found.
The part that makes it actionable is the inlinks panel. Select a broken URL and it lists the pages linking to it, so you know which page to edit instead of knowing only that something is broken.
You can use it free for up to 500 URLs, which covers a large share of B2B sites completely.
What you get.
- A list of every URL returning a 404, found by crawling the site yourself.
- The source pages linking to each broken URL, so every repair has an address.
- Broken links in your own pages and in your outbound links to other sites.
- An export you can hand to whoever edits the pages.
- A crawl of up to 500 URLs at no cost.
How to set it up.
Download the SEO Spider, enter your domain in the bar, and start the crawl.
Watch the 500 URL free limit; if your site is larger, crawl one directory at a time.
When the crawl finishes, open Response Codes and filter to Client Error to see the 404s.
Select each broken URL and read the inlinks panel to find the pages pointing at it.
Export the list with the inlinks column, since a 404 with no source page gives you nowhere to go.
Decide per URL whether to correct the link, redirect the old address, or restore the page.
Use cases
Find the 404s yourself
Crawl the site and list every URL returning a not-found response.
Name the source page
Take the page doing the linking, so the correction happens once.
Audit inside the free limit
Cover a small site in one crawl without buying a license.
Best for
After a site migration
A migration breaks internal links quietly, and a crawl is the only way to find them all.
Older content libraries
Outbound links rot on their own as other people reorganize their sites.
Before a link building push
Pointing new authority at a 404 wastes the link.
