Jagelon Guard – Technical SEO & Site Monitoring

Jagelon Guard gives every site owner a free, one-click SEO Health Check. It reads the public home page, robots.txt and XML sitemap, then explains what is correct, what needs attention and what could not be checked. The audit is read-only, works without an account or key and does not send site data to Jagelon. The plugin also keeps the technical foundations of SEO in order locally inside WordPress. An optional monitoring service checks the public site every 15 minutes and warns you when a quiet change could cost visibility or traffic. Free technical SEO — no account required

• a one-click, read-only SEO Health Check for the home page, robots.txt, XML sitemap, HTTPS, metadata, Open Graph, JSON-LD and the main H1 heading
• an SEO panel in the editor of every page and post: title and description in Google with a live preview and character counter, and a "hide from Google" switch
• home page title and description, with the same preview
• canonical links, with WordPress core's own tag replaced by one you control
• the native WordPress sitemap, without author pages
• robots.txt rules
• Open Graph tags
• Organization and WebSite schema (JSON-LD)
• an optional "business card site" mode for sites without a blog: category, tag and author archives and RSS feeds are hidden

These features run on your own site, do not expire and need no connection key. Optional monitoring every 15 minutes Sites rarely break loudly. An update quietly sets noindex, someone edits a page title that used to rank, a redirect behind a paid ad starts returning 404. The site still looks fine in a browser, so nobody notices for weeks. The optional Jagelon Guard service checks your public site every 15 minutes and tells you what changed, where it happened, how long it has lasted and what to check next:

• an event log in your WordPress dashboard
• a weekly email report, including the quiet weeks
• recommendations ranked by importance, each listing the affected addresses

Jagelon Guard observes and advises. It never changes your content, settings or files. Jagelon Guard reports, the event log and recommendations are currently written in Polish. The free features above are fully available in English. Privacy and resilience Connecting is optional. Without a connection every local feature listed above keeps working. What the plugin sends to the service, and only after you paste a connection key:

• your site address
• WordPress, PHP and plugin versions
• the results of the service's own checks of your public pages
• a timestamp for each connection

It does not send post content, user data, database contents or anything from inside wp-admin. If the service is unavailable, the local SEO features keep working. Only monitoring and reports pause.

0.10.0

• Adds the free, manual SEO Health Check. It works without an account, changes no site settings and clearly separates correct, warning, error and unavailable results.
• The check remains available alongside Yoast SEO, Rank Math and All in One SEO, without producing duplicate metadata.
• Adds same-site request restrictions, nonce and capability checks, a short per-user rate limit, responsive results and deterministic regression tests.

0.9.30

• The plugin is now Jagelon Guard. The previous name could be confused with an unrelated trademark, so the plugin, its text domain and its admin screen were renamed.
• The character counter label is JSON-encoded with escaped angle brackets, so a translation cannot break out of the inline script.

0.9.29

• Admin styles and scripts are loaded through the WordPress enqueue API.
• Structured data (JSON-LD) escapes HTML tags, so no site value can close the script element.
• Translations are delivered through translate.wordpress.org; the package no longer bundles language files.

0.9.28

• Build fix: the paid package is buildable again. The update channel was dropped from the whole source tree instead of only from the directory build, so paid sites shipped since 0.9.18 could no longer update themselves. The directory package is unchanged: it carries no update channel and no Fix module.

0.9.27

• Ready for the Jagelon Guard trial: the expiry reminder counts down 3 days and 1 day for a trial (30 and 7 days for a yearly plan), and the event log stays visible after monitoring stops.

0.9.26

• Screenshots and listing graphics for the plugin directory.

0.9.25

• The settings screen is now fully translatable. The indexing section mixed an English heading with Polish labels, and the event log and recommendations headings stayed Polish on every site, connected or not.

0.9.23

• "Tested up to" is declared only in the readme, where the directory expects it, so the two cannot drift apart.

0.9.22

• Plugin URI now points at the plugin's own page, separate from the author URI, as the directory requires.

0.9.21

• The request URI is unslashed and sanitised before use, as recommended by Plugin Check.

0.9.20

• The SEO panel keeps a readable width after being moved out of the editor sidebar with the "move up" arrow.

0.9.19

• A site set to "Discourage search engines" no longer serves a working XML sitemap, and robots.txt no longer advertises one. Staging copies could be found and indexed despite the setting.

0.9.18

• Jetpack no longer adds a second set of Open Graph tags next to ours.

0.9.17

• SEO panel in the page and post editor: title, description, live Google preview and a "hide from Google" switch.
• Steps back automatically when another SEO plugin is active.
• Hiding category, tag and author archives and RSS feeds is now an opt-in "business card site" setting, and blog posts stay in the sitemap. Sites updated from an earlier version keep their previous behaviour.
• Home page metadata fields explain their defaults, with a Google preview and a character counter.
• The monitoring service is now consistently called Jagelon Guard.
• The settings screen now starts with what already works, a next step and what Jagelon Guard adds, instead of unavailable modules.
• A fresh install no longer reports a lost connection it never had.
• Removed the plugin author's product and e-mail address from the structured data (schema) added to every site.

0.9.16

• Comments and pingbacks are no longer switched off without asking. The setting is off by default.
• English is now the source language; Polish ships as a translation.
• The paid Fix module is no longer part of this package.

0.9.15

• Event log shows the previous and current value of what changed.

0.9.14

• Recommendations list the affected addresses instead of only counting them, with a link straight to the editor.
