Unlinked pages in root directory not in sitemap

[agisthos]

I have a website with the root html directory containing many keyword landing pages. These pages are unlinked from the main website.

So when a sitemap bot crawls the website it misses these pages because there is no path from index.html to any of them.

I still want these pages to appear in the sitemap xml file. Will the paid version of sitemap generator index these unlinked  pages?

Hi, without links to these pages they won't be found or included with both the free online version and the paid version
