I've been rejected by Google Adsense!
The Yola team isn't able to answer questions about Google AdSense program or their policies.
If you have any questions about the AdSense program, consult the AdSense support center at Google Adsense Help. They have a help center with FAQs and a forum that you can post to with AdSense-specific questions.
Using a tool like Yola to create and host your website won't help or hurt you getting into AdSense - all websites are held to a set of eligibility requirements by the AdSense team.
