If I was a member of Google Algorithm design devision I would opt for changing wegihts of different seo signal factors.
1. The most important seo signal should be content quality and quatity. Period.
2. The second should be content readabiltiy and availability.
3. The Third one should be Uesr Expirence
4. The 4-th one should be site’s look and feel
5. The last category should be links and social signals. There are to easy to manipulate. Really.
To have a really good content to have to be an expert or hire an expert. Event if you are an expert it takes time to write something.
