you and @seckorama mentioned SEO and multiple frontends. I know there is a term for claiming the content (where it was originally posted) and only frontend that managed to "keep" it under them is Travelfeed. No idea how they did it.
I have 2-3 posts that are top 10 SEO written on Travelfeed and google always shows TravelFeed link. "Cats Corfu" search is in top 5 results for 5 years now and when ever i check it is Travelfeed front end.
I got decent ranking on Plitvice post. I wrote it in Peakd, but google showed it in Hive.blog for few weeks. Now i did the search and "Plitvice Lakes Photography Tips" was at second page as peakd post. And i tried adding rain "Plitvice Lakes Photography Tips Rain" and it was top 4 result but in ecency 🤷♂ and for some reason non of them have photo preview.
