Generate a meta-prompt designed to create SEO-optimized content.  This meta-prompt should instruct an AI to produce a 500-word article targeting a specific high-traffic keyword. The output should include a title, introduction, several subheadings with supporting content, a conclusion, and a call to action. The meta-prompt must specify the keyword, target audience persona, desired tone (e.g., informative, persuasive, conversational), and SEO parameters such as keyword density, readability score (e.g., Flesch-Kincaid), and inclusion of relevant internal and external links.  The meta-prompt should also guide the AI to analyze competitor content for the given keyword to identify opportunities for differentiation and to incorporate relevant long-tail keywords. The final output should be formatted for easy readability and SEO optimization, including appropriate headings (H1-H6), bullet points, and visuals (mentioning where images or videos would be beneficial).  The meta-prompt should include a validation section specifying metrics to ensure the generated content is effective.  Example Keyword: &#8220;best running shoes for women&#8221;. Example Persona: Female, 25-45, active lifestyle, interested in health and fitness.  Validation metrics should include: Google search result ranking after 30 days, organic traffic generated, and user engagement metrics (time on page, bounce rate).
