An anchor text CTA is the term that is given to a specific kind of text-based call-to-action. In every single post we tracked, the anchor text CTA was responsible for the largest percentage of that post's leads (by far). Between 83% and 93% of each post's leads came from anchor text CTAs and internal link CTAs. The fact that these anchor text CTAs blend in more with the rest of the post may be one of the reasons they perform well. In other words, the anchor text CTA works really well in this case because it satisfies the visitor's need right away -- within the first few paragraphs of the blog post. So while conversion rate optimization experts warn against relying on "best practices," taking direction from them isn't a bad approach when you're just getting started with a new tactic.
