Once you have a clear idea of your brand, you need to find platforms that are relevant, reputable, and reach your target audience. To do this, you can use Google search with keywords related to your niche, topic, and audience to find blogs and podcasts that cover similar or complementary subjects. Additionally, you can follow influencers, hashtags, and groups related to your niche on social media to find blogs and podcasts they share or appear on. You can also use online directories and databases such as Alltop, Feedspot, or Blogarama for blogs and Podcast Addict, Listen Notes, or Podchaser for podcasts. Moreover, analyzing what blogs and podcasts your competitors or peers are guest posting or podcasting on can be beneficial. To assess the quality of potential platforms, look for indicators such as domain authority (using tools like Moz or Ahrefs), social proof (number of followers, likes, shares, comments, and reviews on various social media platforms), and audience fit (demographics, interests, pain points, and goals). Make a list of potential platforms that match your brand and rank them according to these criteria.
