Our system trains itself to recognize good content - blog text, images, videos, etc. - and negate other spaces on a website - ads, other article promotion, bios, etc. Sometimes, the system gets it wrong, but no worries we can fix it!
Keep in mind, you can always manually add and edit your content in Dashboard.
If you haven't done so already, email firstname.lastname@example.org with specifics on the articles that appear incorrect in the app, and what content is being added or missed. As always, screenshots provided are much appreciated!
