I wouldn't have a homepage post to each on the homepage of all 50 if you want to be super safe.
You could use inner pages on 10-15 to post to the second site as long as there's no connections and they both have plenty of other backlinks.
But, you CAN quite safely do it. It's only going to be caught algorithmically if both sites ONLY have those pbns as their backlinks.
You're only going to be in a problematic situation if you get a manual review, but those are pretty damn rare.
So if you have a LOT of budget and are more concerned with safety, build a custom pbn for each site, however, if you want to maximize the money you have, then use your custom pbn for both sites.
To make it undetectable to the algorithm, also add a couple of posts on each blog, linking to 2-3 random sites to confuse the algorithm.
And you don't specifically need to have just tech pbns for a tech site. That isn't natural. Tech sites have links from everywhere.
A health site could link to a tech site with an article about medical technology. A travel site could link to a tech site because it's got an article about the latest boeing, and it's linking to some engine tech. So get creative with your pbns.
BUT, what does matter with your pbn is to make sure the niche of the pbn matches the previous niche of the domain. If you slap a travel site on a domain that was health related, it won't be operating at maximum power.
Hi,
I currently own two ecommerce sites.
Both sites rank very well in google and bing serps.
I have always purchased PBN posts. However, I am looking at setting up my own PBN network.
Approximately 50 sites to start.
Site 1 is tech niche. Site 2 is home niche.
My questions is:
Can each PBN site link out to both sites?
Or should I create two networks - one network for each site?
Thanks!
