You can also statistically click on the Anchor Text for each keyword in the internal Link.

These are user conversion tracking activities, depending on the purpose of the SEO or promotion campaign so that we can track the appropriate conversions. With SEODO, the type of conversion we use most often is click on position (Hotline, Button), page scroll index.

SEODO regularly measures Hotline or Button clicks to get detailed statistics on the effectiveness of Digital Marketing campaigns.
