Some thoughts.
Potential reasons for deindexing:
- OBL count
- OBLs/articles count
- dublicate content (in my eyes nr. 1 reason)
- changing websitecontent after buying an expired domain
- link footprints
- manual reviews from client sites
- hosting issues (dublicate nameservers, too many linking sites on the same a/b-class Ip
No i have various models in my mind to counter these factors:
1.) OBL count
Of course we can lower the OBLs on the mainsite. Also we could just preview articles, so they aren´t homepagebacklinks anymore.
2.) OBLs/articles count
1 Link each article, submitting articles without links
3.) dublicate content
This one is tough. If we write unique content our costs double and it´s way more administrating work. Actually this is only an option for me for permanent blogposts.
Another thing: We can use hyperspun articles with mixed paragraphs. That would lower our costs, make perhaps even a better grammar, but we are damned if we get manual reviews. If we get penalties anyways for manual reviews we don´t have to care. If we are using the links as tier2 links, we don´t have to care neither. Please give me your opinion about that!
4.) changing website content:
The only practical method could be to buy expired domains, rebuild the content through archive.org and just add your links. If You get suied, we won´t cry...not an option for people living in the wrong countries (thoughts on that please)
5.) link footprints:
The only way is to create bigger networks and work more together. So we need better teamwork.
6.) manual reviews for clients
The only thing is building buffersites with good unique content. Of course we won´t building link pyramides if domains become deindexed, so web2.0 plattforms
7.) hosting issues
Paying more, split through more seo hosts, use small hosting packages. There are lots of offers for 4$/month/IP from regular hosting companys.
We need to interact more and share our hosting accounts. The problem is if there are more sites on the same IP, that could also higher the risks that all from the same IP become deindexed.
