Redirect Doctor

You have been redirecting URLs for years. Every rename, every restructure added one more rule — and nobody ever went back to check whether they still make sense together. Redirect Doctor reads the redirects you already have and tells you what is wrong with them.

The nine tabs, one by one, on a real site.

The diagnosis

Nine screens, nine ways your redirects are costing you

Everything is measured against your own site. No external service is contacted, no data leaves your server, and nothing is written unless you tick a box.

Chained redirects

Address A sends to B, which sends to C. Your visitor travels from page to page before arriving, and Google reads that cascade as an SEO flaw. On an old site, cascades of eight steps are common.

Loops

A sends to B, and B sends back to A. The browser gives up and the page never opens. This is the only fault that truly breaks something for a visitor.

Conflicts

The same address with two different destinations. Only one can win, and it is not always the one you meant.

Duplicates

The same rule written several times over the years, by several people, without anyone noticing.

404 errors, grouped

Not a raw log, but the pages people actually keep asking for, grouped and sorted by how often they are hit — with a suggested destination for each.

Sent to the home page

These rules do not send the visitor to a replacement page. They send them to the home page, and Google reads that as a soft 404. Your home page slowly takes on the reputation of every dead address pointed at it. The honest answer is 410 Gone.

Doubtful destinations

Redirects that work, but whose destination shares no word at all with the address being redirected. The visitor asked for one thing and receives another. Google treats it the same way, and the redirect passes on nothing.

Safe to delete

Rules that have not sent a single visitor in years. The plugin shows the date each one was last used: after three years without a visit, the risk is close to zero.

Links to fix in your content

The posts, pages, courses and products that still link to an address which now redirects. Fixing the link removes the hop at the source, where it was born.

What Redirect Doctor does

It reads, it sorts, it leaves the decision to you.

Redirect Doctor does not create redirects behind your back and it does not replace your redirection plugin. It examines the ones that already exist, cross-checks them against each other, and shows you what no plain list ever shows: what contradicts itself, what goes round in circles, what no longer serves any purpose.

Nothing is written without you. Every fix takes a ticked box and a click, and the last batch stays recoverable — an undo button appears at the top of the page.

The analysis re-runs by itself once a week, and immediately after any change you make.

Redirect Doctor inside the WordPress admin: the tiles count 25 linked redirects, 3 loops, 1 conflict, 13 duplicates and 1,605 404 errors, and the screen lists the rules that have been unused for years

The printable health check

A document you can hand to your client

One button, and everything found on the site fits into a self-contained document: the quantities, and the risk each one represents. It names no address — which is exactly what makes it shareable. It goes out as it is, in a quote, in a project report, or in an email to a manager.

Pricing

The diagnosis is free. What you pay for is the repair.

An AI can read a list of redirects in ten seconds. It cannot open your WordPress database and rewrite eight hundred rules. That, and only that, is where the work is.

The diagnosis

Know exactly what is wrong.

All nine screens, the filters, the search, the CSV export and the printable health check. The counters are the real ones: if your site has 1,609 unresolved 404s, it says 1,609 — never rounded, never capped.

The first five rows of each table, and how many more there are
The printable health check, shareable as it is
No fixing: every action button stays visible, but switched off
