Home page ranking dropped below internal pages

[OptioPublishing]

The index page for a site I manage has dropped significantly - internal pages rank above it. It's a new site, 2 months old but was ranking at 1st. Any suggestions as to how I can debug this?

There are many factors involved. Too many to properly do so in a Q&A unless you can share the URLs involved.

How exactly did you determine your internal pages rank above the home page?

What quantity and quality of backlinks do you have for your internal pages and home page?

Agree are you talking about a specific keyword ? It could make sense that an internal page would be ranking higher than a homepage on a keyword due to on-page content of the page.
