I see that you have two domains, https://www.joomlacontenteditor.net/ and https://jce-editor.com/
I think you need to create a 301 redirect from one the other, with your most visited as a canonical domain.
This can solve some problems, like cookie issues if i have https://jce-editor.com/ in bookmark and i access to the site from Google SERP that show me https://www.joomlacontenteditor.net/. In this case mCan uniform your results in SERP and obtaining a more SEO compliant website.
I had problems with a renew of subscription some time ago, because i was inside jce-editor.com and not inside http://www.joomlacontenteditor.net. For some reasons Paypal doesn't let me to pay.
I hope this can be useful.
PS: edit you home page "meta title" too, now it show only "Home", that is not so good for SEO: add something like "JCE - Joomla Content Editor". Only in home page ;-) by the field in menu voice, not in Joomla Global Config. (meta title, meta desc and meta key in global config must be empty)
In "meta description" (in home page menu voice) add a "meta description" like "JCE makes creating and editing Joomla!® content easy: get the power to create the kind of content you want, without limitations, and without needing to know or learn HTML, XHTML, CSS."
