Yes, Squirrly works with Elementor websites and offers complete SEO and Content Optimizations in real-time with Elementor.
The SEO Live Assistant Module of Squirrly SEO works on the front-end of Elementor, just as you’re creating or editing your Elementor page. Squirrly was the first WordPress SEO Plugin to offer this and provide Content Optimization in real-time (with as-you-type advice).
The only thing you need to do is make sure that the option Activate Live Assistant in Frontend is ON if you are using Elementor.
You can access this option from Squirrly > Live Assistant > Settings.
