The fight between Google and SEOs is a 1984ish Perpetual War that will never end.
It’s undeniable that Google’s winning that war at the moment.
Google cracked the code with the HCU. They’re now able to identify/destroy SEO sites. The March Core Update was the double-tap that made sure dead sites stayed dead.
It’s safe to say that standard on-page SEO tactics are counterproductive at this point.
Off-page SEO hasn’t changed. If you built links then you sailed through these updates with minimal damage and possibly even saw your traffic increase.
But based on the extreme amount of whining on SEO X it seems like a lot of people decided to just spam content w/o building links. It is what it is. You can lead a horse to water but you can’t make it do anything. Everyone hates and fears hard work and ESPECIALLY hard work that comes with extreme levels of uncertainty/rejection. The path of least resistance is always going to be the road most traveled.
But that’s besides the point.
Standard on-page SEO is dead
The main thing that Google wants to destroy is hyper-optimized content.
As much as I hate to say it, that means that pretty much all SEO optimization tools are now toxic AF.
