Internal pages no longer appear in Google search results?

I have a situation when a home page is showing up for specific keywords that used to give traffic to internal pages. Internal pages are optimized for these keywords, they are more relevant than the home page but no longer appear in Google search results as they used to. There is no a single internal page that gets traffic from Google, the home page does.

What are possible reasons? Is it penalty? lack of deep linking from external sources?

 

Hello,
Check out on Internet about Google Panda update, maybe you were affected.

its lack of deep linking, I think u must deep link your site as well

 

Definitely lacking the link juice flowing from your home page to the internal pages.

 

You probably don't have enough links pointing to your internal pages. Whoosh!

 

Improve your internal link structure and try to generate backlink for inner page as well.

 

Do proper internal linking and increase backlink of inner pages.

 

If your internal page are not showing result on SERP then you have to work for the internal page like the home page. Back link of the internal page help to improve SERP ranking

 

First, check the internal linking structure of your website…. Your every webpage must be linked to at-least one page of the website.
Second, go for deep linking…. It is very important to get relevant backlinks for your inner page. If you think they are more valuable to the user, you can use them in anchor text.
