Sorry for the pretentious title.
But this is what I truly started to believe many years ago.
Each time I open Google and search for something, I’m overwhelmed with dozens of articles written not by professionals, but by content makes and SEO gurus.
The initial goal of such articles is not to help, but to sell a service. The quality of content is much lower than if an answer is given by a passionate professional.
Another lame thing is that content writes will always provide texts with a number of characters recommend by SEO gurus. So even if you ask Google a simple yes-no question, you will still have to read 300-2500 words.
This makes my search experience worse. More often I search directly in communities and forums (e.g. Stackoverflow), not in Google.
This is actually a signal for the “not evil” corporation. If it gives bad search results, people will not use it.
This is why I believe we will meet huge changes in the ranking algorithms. To save money Google needs to save the quality and therefore learn how to detect content made by real experts.
Therefore I think the best SEO strategy today is investing in yourself.
Invest in your skills and experience, get yourself to know valuable rare stuff. Become a professional. Get a certain point of view on a subject.
Google will value this much more than the number of backlinks you asked from another bloggers.
