NO ES POSIBLE comparar más de tres dominios con ayuda de Brecha de palabras clave.

The statement is false because Semrush's Keyword Gap tool allows users to compare up to five domains simultaneously. This feature is crucial for competitive analysis, enabling you to identify keyword opportunities by seeing where your competitors rank but you don't. Comparing only three domains would limit the scope of competitive intelligence, making it harder to get a comprehensive view of the market. Therefore, the ability to compare five domains provides a more robust analysis for identifying content gaps and SEO strategies.
