Frequently Asked Questions

Will this plugin automatically correct link URLs on my website?

No, but it will automatically find any broken URLs in a post and list them for you, so you can review and correct them.

Will it find broken image URLs, too?

Yes, the plugin will ping every URL in your post’s content, no matter if it’s in a link, an image or even in a shortcode.

Will the plugin prevent a post with broken links in it from being published?

No, it will just list any broken URLs for you, but it will do so already when you save a draft. Most people save a draft multiple times before they publish it, so there’s a fair chance you’ll notice any broken links before actually publishing.

If you want to to avoid accidental publishing, try the free Publish Confirm plugin. It will add an extra confirmation dialogue for the publish button.

What about any relative URLs?

Relative URLs will not be checked.

Does it matter whether a URL is http or https?

By default the plugin will try to ping both, http and https URLs. If needed, you can change accepted protocols via hook. For example, in order to check only URLs with SSL:

add_filter( 'spcl_acceptable_protocols', 'set_spcl_acceptable_protocols' ); function set_spcl_acceptable_protocols( $schemes ) { return array( 'https' ); }

Will this plugin optimize my site for search engines (aka SEO)?

While the term “optimize” would surely be an overstatement, this plugin can surely add a fair share to the link sanity on your site. Link sanity is a pretty important SEO factor.

Where’s the settings page?

There is none, no configuration necessary.
