Listly by Ed Brancheau
Here's a list of steps that need to be taken to build an effective OMG-style PBN. Please feel free to add your own steps and vote up or down the others.
The main goal of this list is to create a list of steps that need to be taken when we build a PBN from buying domains to publishing new content on a regular basis.
Make sure that a site/page is already indexed before you link a PBN to it or the PBN might get deindexed
Make sure that a domain has at least:
Click on "Taxonomies" - Under the "Categories" AND "Tags" section click the boxes "Meta robots: no index, follow". Save. Click on the "Other" tab next to "Taxonomies" and do the same for "Author Archives" section - click box "Meta robots: no index, follow"
You can use grammarly.com to check your grammar score. If grammar score is low (like below 85 - the higher the better though), either manually review the article (with the help of something like microsoft word) or use grammarly.com (monthly subscription) to help you with it.
Build social properties, send social links (social explosion is good), build citations of a local site, do some DAS if an affiliate site - get the trust of the site going before sending PBNs directly to the site.
This will create a barrier where if you do mess up in research and get a "bad pbn" - it has a much less chance of hurting you (trust of site has been built AND you have a high DA property acting as a barrier).
