Nothing about your site is sent to us or to any third-party service. * **No limits.** Check 50 links or 500,000. There is no paid tier holding back features. * **Light on your database and server.** One row per unique URL (a link used in 300 posts is checked once), small background batches that stop after 20 seconds, and nothing at all runs for your visitors. * **Fewer false alarms.** A timeout or server error is re-tested before it is called broken. Sites that block automated checks (LinkedIn, some shops and social networks) are listed separately as « Blocked » instead of cluttering your broken-link list. * **Smart internal checks.** Links to your own posts are checked directly in your database — no web request — so it also catches links to drafts, private posts and posts in the trash. #### What it checks * Links (``) in posts, pages and any public custom post type. * Images (``) — including image files missing from your uploads folder. * Links within your own site — always. * Links to other websites — once you switch this on (it is off until you agree; see the FAQ). * Redirects — see where old links now point and update them to the final URL. #### Fix links in one click From the **Broken Links** screen you can, for any link: * **Edit URL** — type the new address once and it is updated in every post that uses it. * **Unlink** — remove the link but keep the text. * **Update to new URL** — replace a redirecting link with the address it now ends up at. * **Not broken** — dismiss a false alarm; it stays dismissed. * **Recheck** — test again right now. Every fix is saved as a normal post update, so a revision is created and you can always undo it. Bulk actions let you fix many links at once. #### Everything else you need * Filter by Broken, Needs confirmation, Redirects and Blocked, and search by URL or link text. * See the link text and every post that contains each link. * Count of broken links in the admin menu and a Dashboard widget. * Optional daily email when new broken links are found. * Optional: add `rel="nofollow"` to broken links until you fix them. * Optional: strike through broken links on the front end — visible only to logged- in editors. * Exclude URLs or whole domains (wildcards supported). * Export any list to CSV. * WP-CLI: `wp link-checker scan` and `wp link-checker report`. * Uninstalling removes every table, option and scheduled task the plugin created.

Install the plugin from **Plugins Add New** (search for « IntellectSight Broken Link Checker »), or upload the `intellectsight-broken-link-checker` folder to `/ wp-content/plugins/`. 2. Activate it. 3. Open **Link Checker Broken Links**. Links within your site are checked straight away; keep the page open to see results within a minute or two, or leave it and checks continue in the background. 4. To also check links to other websites, click **Also check links to other websites** on that screen (or enable it in Settings). 5. Optional: open **Link Checker Settings** to choose content types, excluded URLs and email notifications. ## FAQ ### Do I need an account or an API key? No. The plugin works entirely on your own server and never contacts any service of ours. ### Does the plugin send data anywhere? No. The plugin never contacts IntellectSight or any other service, and it collects no usage data. To find out whether a link to another website still works, your server has to request that link. This is off by default: the plugin only checks links within your own site until an administrator turns on « Check links to other websites ». When it is on, your server requests only the addresses that appear in your own content, using a generic user agent that does not include your site’s address. You can exclude any domain or URL in Settings. ### Is there a limit on how many links it checks? No. ### Will it slow down my site? No. Nothing runs when visitors view your pages (unless you turn on the optional nofollow or strike-through features). Checking happens in the background in small batches every five minutes, each limited to 20 seconds, and the plugin never sends more than a few requests to the same website at a time. ### Why is a link listed as « Blocked » instead of « Broken »? Some websites (for example LinkedIn, Amazon and many social networks) refuse requests that do not come from a normal browser, answering with codes like 403, 429 or 999 even when the page works fine. Rather than wrongly report these as broken, the plugin lists them under « Blocked » so you can check them in your browser. ### What does « Needs confirmation » mean? The link failed once with a timeout or a server error. Websites have bad moments, so the plugin tests it again a few hours later before reporting it as broken. You can also click « Recheck » to test it now. ### Can I undo a fix? Yes. Every change is saved as a normal post update, so you can restore the previous version from the post’s Revisions screen. ### Which content does it check? Published posts and pages by default. You can add any public custom post type in Settings. ### Does it work on large sites? Yes. Links are stored once per unique URL in two small indexed tables, and all work is done in time-limited batches. On very large sites you can also run a full scan from the command line with `wp link-checker scan`. ### Where is my data stored? In two database tables on your site (`wp_isblc_links` and `wp_isblc_instances`). They are removed when you delete the plugin. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “IntellectSight Broken Link Checker” is open source software.
