If you save a website from which no information gets extracted even if there is information to extract, or if not all information gets extracted you can do one of two things:

• Inform us. This can be done by clicking on the exclamation mark in the top right corner of the entry. We will then try to add support/fix the issue asap.
• Add support by yourself. That can be done with our “Data Selector” on the top of the page. “Plugins -> Data Selector”.
