Substack is an all-in-one publishing platform designed for writers, creators, and startups to host newsletters, blogs, podcasts, and videos directly to subscribers' inboxes. It's ideal for founders in Content & Blogging who want a simple, free tool (no cost unless monetizing) to build an audience, share updates, and embed rich media like links to their products. With features like customizable designs, analytics, community comments, and Notes for quick updates, it combines blogging and email marketing seamlessly.

For SEO value, Substack offers backlinks from its Domain Rating 23 domain when you include product links in posts. Analysis shows about 75% of backlinks are dofollow, often on established newsletters with more posts and followers—newer ones may start as nofollow. Its discovery tools (recommendations, directory, referrals) drive organic traffic and subscriber growth, amplifying link visibility without extra marketing effort.

Tips for startups: Sign up for free, publish consistent posts with natural product links, and grow followers via recommendations and Substack Notes to increase dofollow chances. Enable community features for engagement, use the rich editor for embeds, and leverage analytics to refine content—aim for long-term presence over quick wins.
