Started working on a site and learned that the person before me had done a fairly sketchy maneuver and am wondering if it's a net gain to fix it.
The site has pages that it wanted to get third party links linking to. Thing is, the pages are not easy to naturally link to boost them in search.
So, the woman before me started a new blog site in the same general topic area as the first/main site. The idea was to build up even the smallest bit of authority for the new blog, without tipping Google off to shared ownership. So, the new blog has a different owner/address/registrar/host and no Google Analytics or Webmaster Tools account to share access to.
Then, as one method of adding links to the new blog, she took some links that originally pointed to the main site and re-directed them to the blog site.
And voila! ...Totally controllable blog site with a bit of authority linking to select pages on the main site!
At this point, I could un-redirect those links that give the blog site some of its authority. I could delete the links to the main site on the blog pages.
However, on some level it may have actually helped the pages linked to on the main site.
The whole thing is so sketchy I wonder if I should reverse it.
I could also just leave it alone and not risk hurting the pages that the blog currently links to.
What do you think? Is there a serious risk to the main site in this existing set up? The main site has hundreds of other links pointing to it, a Moz domain authority of 43, thousands of pages of content, 8 years old and Open Site Explorer Spam Score of 1. So, not a trainwreck of sketchiness besides this issue.
To me, the weird connection for Google is that third party sites have links that (on-page-code-wise) still point to the main site, but that resolve via the main site's redirects to the blog site. BTW, the blog site points to other established sites besides the main site. So, it's not the exclusive slave to the main site.
Please let me know what you think. Thanks!
