Ahrefs’ Traffic Value (TV) shows:

Ahrefs' Traffic Value (TV) estimates the cost of acquiring the same amount of organic search traffic through paid ads (PPC). It calculates this by multiplying the estimated organic traffic to a page or website by the average CPC (Cost Per Click) of the keywords driving that traffic. This metric helps users understand the monetary worth of their organic search performance. The option "The value of searches if they were to be acquired via PPC ads" is incorrect because TV specifically measures the value of traffic (visitors), not just the searches themselves. "The value of organic traffic as estimated by Google Keyword Planner" is incorrect because Ahrefs uses its own data and algorithms, not directly Google Keyword Planner's estimations, for this calculation.
