- ●Cyrus Shepard's recent AI citation ranking factors study highlights the distinction between correlation and causation in SEO, particularly regarding direct traffic as a ranking signal.
- ●Direct traffic should be viewed as an indicator of brand strength rather than a primary driver for rankings, as high direct traffic does not guarantee good SEO performance.
