Frequently Asked Questions

Does this plugin work with page builders?

Yes, the plugin processes links in content regardless of how they were added, including page builders like Elementor, Beaver Builder, etc.

Will this slow down my site?

No, the plugin uses efficient server-side processing and only runs on content that's being displayed. Performance impact is minimal.

Can I exclude specific links?

Yes, you can exclude links by adding the no-external CSS class or by adding domains to the exclusion list.

Does it work with caching plugins?

Yes! The plugin offers two processing modes:

• Server-Side (PHP): Processes links before content is cached (recommended for SEO)
• Client-Side (JavaScript): Processes links after page load, perfect for heavily cached sites

You can choose the mode that works best for your setup.
