I have 10 quality domain sites setup to build tier 1 links. At what point is it safe to stop publishing articles on these sites and move on? I was thinking of publishing 6 or 7 quality articles per site, not counting the featured article pointing to my main money site. Is it okay to have less than 10 articles on sites with 30-50 DA & PA, and stop pushing new content? All post dates are removed after 1 year in case anyone was wondering. I understand that it's beneficial to continually improve the overall link value of these sites, but there's only so much time in the day. I anticipate adding more sites to the PBN in the future as well.
