Joomla Core Pages Delisted

[Leadhub]

Hey Everyone,

This query may be more for a Joomla developer or someone that has had a similar issue. I'm not really looking for answers like, "check Google Search Console" or anything like that.

We have a client who recently had all of their core pages delisted in Google but the blog is still being displayed in search results. For example, if you search "company name" they have a blog post that ranks #13 or so organically. I tested Google Search Console and Google is saying that the site is temporarily unavailable.

We haven't made any changes or updates to Joomla's core structure so I'm unsure as to where this change is coming from. Here are some items we've checked:

1. Site searches within Google, resulted in seeing core pages are not indexed but blog pages are

2. Google Search Console - looked for manual actions (none found), looked at sitemap errors (nothing mentioned), looked at robots.txt (no issues here), attempted to fetch the site as Google (temporarily unavailable).

3. Called the hosting company (Rackspace) to discuss potential issues. They were extremely helpful but we were unable to find anything.

The blog is actually a Module that was added so I'm thinking something has changed to block Google bots from the core Joomla structure but it hasn't blocked them from the blog structure.

Without putting the company name or url on blast, has anyone heard of or experienced anything like this? Any help or insights would be much appreciated!
