Which of the following is not a use case of portfolios:

Ahrefs Portfolios are designed to help users organize and monitor groups of websites efficiently. They allow you to group competitor websites for industry analysis, run SEO experiments by comparing performance across sites, and monitor keyword rankings at scale for multiple domains. Optimizing content with AI is not a direct feature of Ahrefs Portfolios. While Ahrefs provides tools for content analysis and keyword research that can inform AI-driven content optimization, the portfolio feature itself is for grouping and monitoring websites, not for AI content generation or optimization.
