Turning off a subdomain

[Blink-SEO]

Hi! I'm currently working with http://www.muchbetteradventures.com/. They have a previous version of the site, http://v1.muchbetteradventures.com, as sub domain on their site. I've noticed a whole bunch of indexing issues which I think are caused by this. The v1 site has several thousand pages and ranks organically for a number of terms, but the pages are not relevant for the business at this time. The main site has just over 100 pages. More than 28,400 urls are currently indexed.

We are considering turning off the v1 site and noindexing it. There are no real backlinks to it. The only worry is that by removing it, it will be seen as a massive drop in content. Rankings for the main site are currently quite poor, despite good content, a decent link profile and high domain authority.

Any thoughts would be much appreciated!

Sounds like the indexing issues are causing some drops in ranking, even though good based content and domain authority are present.

Also, the .v1 site looks to be a testing platform?Could that be possible? I recently had an issue with an enterprise client site with very similar issues - with multiple testing versions of the domain up and indexable, causing massive amounts of duplicate content, indexed content and indexing issues.

I would plan to assess any content that could me migrated over to the main site from the .v1, and 301 redirect (and rel-canonical) the old .v1 site pages. Keep those in place for a few months to ensure that all the value of the 301 take effect.

By migrating some of this valuable content over (or all of it), just make sure you use both properly executed 301 redirects, and to take it a step further, apply the canonical tag on the .v1 pages with redirects to the exisiting and correct pages on the main domain. This way, we know for sure all any value is being passed.

SIDE NOTE: Having that many pages, indexed content doesn't mean the site will do well. In fact with this poor setup, the site's massive amount of page URL's might be causing more damage. Too many pages will bad page quality scores can and will bring a site down. Plan to migrate the pages or sections of the site to the main domain (that hold the most value), 301 and rel-canonical the other's, and remove the bad pages with little to no value that may be causing site wide damage in search indexing.

In dumping lots of content from the site - redirect those URL's (being dumped) to a helpful 404 page, which will try to salvage any user hitting the page, and redirecting them to back into sections of pages of the site. Also - make sure that page has a useful 'search' option that is clear to allow them to search for something they might have tried to land on through organic indexed content.

Finally, once you see indexing improve and redirect those pages automatically in the SERP's through reporting in weeks or months to come, then you can shut down the old .v1 pages without fear of losing any value you had.

It's a lengthy process and a big project, but the client (and site) should see huge value in the time you are taking to manage it. It will maintain value for the site in the long run and help build a better platform going forward.

Cheers!
