Content is the core of your social media optimization. You need to create content that is valuable, relevant, engaging, and shareable for your audience and your platforms. You also need to optimize your content for keywords, hashtags, images, videos, captions, headlines, and calls to action. Additionally, you need to optimize your profiles and pages to make them attractive, informative, and consistent with your brand identity and voice. You can use tools like Canva, Buffer, or Hootsuite to help you create and optimize your content and profiles.
