PBN not indexed articles

Hello I have a problem, I have a small network of 5-10 domains and I publish articles about a certain niche about every 3-4 days.
I buy domains with expired or auctioned domains that are already 2-3 years old.
The posts are generated using a plugin in gpt chat, all articles have about the same content but all are unique.
Landings on wordpress are pretty simple
I index my links through Google Search Console
I use one hosting with different ip addresses, also to each site I bind a separate cloudflare to dns records were different.

I need that the articles on a particular keyword were always in the index, ranking is important to me.
The problem is that after a while the articles disappear from the index on the key, although the GSC says that they are still in the index, but it is not so.

I think that Google just bans my site because judging by the metrics, traffic stops coming.
I need someone to help me solve this problem so that my articles do not disappear from the index anymore

This issue likely seems to be Google detecting Low quality or Duplicate content across your network.

Improving content uniqueness and authority signals and diversifying your link building strategy might help prevent De - indexing.

It sounds like Google might be picking up on your PBN setup. For content, you might want to add more depth and variety to make them stand out to prevent low quality or similar patterns.

Be cautious with expired domains, some could have a negative history with Google, so it’s worth running a thorough audit before using them.

If you use any AI articles you can make them unique but not quality ones, so do some rewrites after you publish it

because even there are lot of AI people are doing some tricks to make it as quality so try to some techniques

Make sure higher content uniqueness, vary hosting setups and avoid patterns to maintain indexation.

Check the content quality and improvise the articles richness. And you can re-submit the link again for index after the updates which might be workout.

Ensure that your articles provide real value. Even if they are unique, if they don't offer in-depth insights or engaging information. Try to vary the Content not just the wording but also the structure and the topics covered. Promote your articles on social media platform.

Build backlinks from reputable websites. This will improve your domain authority and rankings.

As many said, check your content and diversify the backlink profile.

How many results does a site:domain search give for your expired PBN domains? If it's around 4 results only, then Google has likely recognised your domains are being repurposed for SEO use and has discounted them.

so AI content is of shitty quality
try to put crowd links and index them
additionally try to index these pages through indexing services

I would offer not to create content on the same topics - AIs usually don't write well under such conditions. So create better content and try to reindex it. Good backlinks to this content should also work well, they don't have to be expensive: I use Medium or Twitter posts, it usually helps.

With the number of domains in the network being too small <10, I don't think Google will penalize you like a PBN network.

The indexed keywords are jumping, and can't rank, usually because your PBN is weak, or the SEO keywords you choose are too competitive.
