Try googling "root M89 tablet".

The first three result lead you to fake android blog telling you how you can easily root every chinese android device and specifically the M89 tablet...

The real authoritative result (xda-developers) only appears in the fourth position, under sight. It will tell you if you follow the instruction given in the fake blog post from the 2 or 3 first results, you will brick your tablet.

In a similar way the word "cbd" (for cannabidiol) has been hijacked by dubious commercial compagnies through fake blog posts filling pages after pages of google results telling you how great cbd is for the treatment of every disease on earth... But there is no trace of an actual study in these results. You will have to go with the less popular word "cannabidiol" to start to see some serious articles about it.

Google results can be hijacked and Google do little about it. May be because the ads shown in these fake blog posts are from google ads network ? I don't know...

But google result have clearly deteriorated these last years and the authoritative figure of the companie is not anymore what it was in the past.
