A: Hi. Thank you for reaching out.

We don't support Gutenberg at this point. But is is, of course, on our to do list.
But, SEO Generator is built to work together with your WordPress Theme. This will give you the freedom to use your own the design, instead of ours. The landing pages you create, will share the styling with the rest your website

Furthermore, we did add Elementor compatibility in SEO Generator version 2.2.0 (and newer). In short, this means that you can use Elementor to design the landing pages that you generate with the SEO Generator plugin.

We've also created a manual on our website about using SEO Generator with Elementor:

Feel free to follow-up if you have any further questions!

Kind regards,
Tim & Jeroen
