Common questions
Frequently asked questions
Is Airygen SEO really free?
Yes. The plugin is free on WordPress.org, with no locked features, no account and no limit on the number of sites.
Do I need any technical knowledge?
No. Most features are configured from the plugin's settings screens, and the setup wizard covers the essentials.
Will it work with my theme and other plugins?
It works with standard WordPress themes and supports both Gutenberg and the Classic Editor. Avoid running a second SEO plugin at the same time — duplicate meta tags and schema can conflict.
