Description
Site Diagnostics and Redirects watches two things other plugins treat separately: your redirects and your crawl health. Everything in this package works out of the box – there are no locked features, no trial periods, and no required external accounts.
- Redirect governance: stores redirect rules, then analyzes them for conflicts (duplicate sources), loops (A->B->A), chains (3+ hops, with hop count and final target), and invalid rules (missing slash, self-redirect, bad status code). One click collapses every chain so each source points straight at its final target. Conflicted sources are excluded from analysis until you resolve them.
- Crawl diagnostics: on demand, loopback-crawls your published posts and pages, builds a status histogram, and lists broken URLs (4xx/5xx), orphan pages (no internal link points to them), and redirecting URLs.
- Redirects actually serve on the front end, after chain collapse, so a chain never costs your visitors extra hops.
- Regex redirects: mark any rule as a regular expression and use $1-style backreferences in the target, so one rule can move an entire section (e.g. /blog/(\d+) -> /posts/$1).
- Hit telemetry: every rule shows its hit count and last-hit date, so stale rules are easy to retire.
- 404 monitor: every miss is logged with referrer, count, and last-seen, and each row has a one-click “redirect it” action.
- 404 pattern suggestions: groups similar 404s into one regex rule you can apply with a click.
- Permalink guard: rename a published post or page and the plugin automatically adds a 301 from the old URL.
- Scheduled crawl: a weekly or daily WP-Cron crawl compares against the previous run and raises a dashboard notice (and optional email to a recipient you choose) when NEW broken URLs appear.
- External link checks: bounded, cached HEAD checks on the outbound links found in your latest crawl (up to 20 per run).
- Import/export: Redirection-compatible CSV plus JSON, both ways, with a diff preview before any import is written.

FAQ
-
Does it crawl external sites?
-
No. It loopback-crawls your own published content, which is the crawl you are responsible for. The external link check only HEAD-requests the outbound URLs already found on your own pages.
-
Is any feature locked behind an account or license?
-
No. Every feature in this package is fully unlocked.
-
What happens to a conflicted redirect?
-
Both copies are flagged and the pair is excluded from chain/loop analysis until you delete one.
