Google's cache is not updated for months and doesn't match "fetch as Google"

Question

I used webmaster's Fetch as Google tool to see how my website looks on Google. The snapshot of rendered page returned by Google is exactly same as my website so I submitted it for indexing.

Logically Google's cached copy of this URL should have been updated by Google but it didn't change and now it's been almost 6 months since the last change. Here is URL for cached copy of this above Page: http://webcache.googleusercontent.com/search?q=cache:http://paintcollar.com

It is not happening with all pages. A few pages are being cached properly. Just to give you an idea, this URL is cached properly: http://webcache.googleusercontent.com/search?q=cache:paintcollar.com/aneel

What is the cause of the problem and how to solve it?

Answer 1

You can use the Remove Outdated Content tool in Search Console. Submit the URL and click through the dialogue box:

1. Has the page been removed or updated? Yes.
2. Click "Next", and select "The snippet and cache are outdated."

Sometimes this issue can be traced to a specific cause, but often it's simply a glitch on Google's part. I suspect the latter's the case here.
