Well, I got it now. Honestly, it's hard to explain because my post will be posted on other Dapps (like peakD, Hive blog, Ecency, etc.) at the same time. And I never experienced anything like this in the digital marketing world. Because everyone just posts on their blog/website at first, then on the other blog.
My explanation -
The search engine looks for duplicate content and usually takes the first one (where you posted first) to rank and completely ignores other sites. Sometimes Google picks the site with the best ranking; it's rare, though.
And Google is not going to penalize other websites for duplicate contents unless it's copyrighted. It won't affect the SEO of other websites - they won't just get any organic traffic from the search engine for that content.
Here's is an example for you. This is the same content that you'll find on Ecency and other Dapps as well. But it ranked Hive Blog on Google (4th number at this moment) with the keyword "earn cryptocurrency by writing." It didn't rank Ecency or other Dapps as I focused on rank the Hive Blog with this keyword.
But it won't affect Ecency or other Dapps. They won't just get any traffic from search engines. That's it!
I hope I've answered your question. I believe there are some SEO experts in the chain, who can explain better. Thanks a lot. :)
Thank you for your answer. Yes, that's what I was wondering too, I didn't go into it looking at the same posts on the rankings but apparently, it's not a problem. It's interesting though, it occurs in systems where websites pull content from the same database. In our case, the Hive blockchain database.
