Content marketing is a strategic approach to create and distribute valuable and relevant content that attracts and retains your audience, and that drives them to take action. To audit your content marketing, you should have a documented strategy that defines your goals, your audience, your value proposition, your content types, your distribution channels, and your metrics. Additionally, you should produce high-quality and original content that matches your audience's needs and interests. Furthermore, you should optimize your content for SEO with appropriate keywords, headings, meta tags, images, and links. You should also distribute your content on the right platforms and formats such as websites, blogs, social media, emails, podcasts, videos or ebooks. Lastly, you should measure and track your content marketing metrics such as traffic, leads, conversions, shares, comments and retention in order to align with your objectives.
