Clarify Scope</h3>\n<p>Identify which goals apply (formatting, SEO, growth, monetization) and confirm the topic. If the request is ambiguous, default to producing SEO metadata and a formatted structure outline simultaneously.</p>\n<h3>2. Visual Formatting</h3>\n<ul>\n<li>Structure content with <code>Heading 1</code>, <code>Heading 2</code>, and <code>Heading 3</code> to improve readability and facilitate search-engine crawling.</li>\n<li>Apply the centering and styling techniques described in <code>references/formatting-best-practices.md</code>.</li>\n<li>Insert native engagement tools (Subscribe button, polls, Leave a comment) at natural breakpoints in the post.</li>\n</ul>\n<h3>3. SEO and Metadata</h3>\n<p>Produce the following fields for every post:</p>\n<ul>\n<li><strong>Title</strong>: 40–60 characters. Use clear modifiers, keywords, and authority signals (e.g., \"Tested\", \"Complete Guide\"). Avoid vague or clickbait phrasing.</li>\n<li><strong>URL Slug</strong>: 3–5 main keywords only, no auto-generated numbers, no dates (keeps the post evergreen). Example: <code>/substack-seo-strategy</code>.</li>\n<li><strong>Meta Description</strong>: 155–160 characters, includes the primary keyword and an implicit call to action.</li>\n<li><strong>Image Alt Text</strong>: Describe the image for accessibility; incorporate article keywords organically.</li>\n</ul>\n<p>Consult <code>references/seo-output-example.md</code> for a worked example.</p>\n<h3>4. Growth Strategies</h3>\n<ul>\n<li><strong>Substack Notes</strong>: Publish short snippets derived from the post to Notes immediately after publishing. Leave authentic comments on related publications to build name recognition.</li>\n<li><strong>Recommendations rotation</strong>: Review Analytics monthly to identify which partner newsletters drive inbound traffic. Rotate recommended partners every 30–60 days to maintain reciprocal growth.</li>\n</ul>\n<h3>5. Monetization (Free → Paid Conversion)</h3>\n<ul>\n<li><strong>Tease &amp; Convert</strong>: Publish the core article freely, but gate a utility bonus (template, spreadsheet, prompt set, audio) behind the paywall. Prove value before asking for payment.</li>\n<li><strong>VIP outreach</strong>: In the Dashboard, filter subscribers by engagement score (4–5 stars), then send a targeted direct message offering a special rate or exclusive invite to the paid tier.</li>\n<li><strong>Welcome email</strong>: Customize the automated welcome email to introduce the author, set publishing cadence expectations, and link to the three best existing articles. Never leave the platform default.</li>\n<li><strong>Homepage taxonomy</strong>: Group posts into Tags (equivalent to newspaper sections) and add them to the navigation bar via <em>Website Themes</em> for advanced content discovery.</li>\n</ul>\n<h2>Quality Checklist</h2>\n<p>Before delivering output, verify:</p>\n<ul>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Title is 40–60 characters and contains the primary keyword.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> URL slug has 3–5 words, no numbers, no dates.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Meta description is 155–160 characters with a keyword and implicit CTA.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> All images have alt text.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Subject line (if applicable) is under 50 characters and free of spam triggers.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> At least one native engagement element (button, poll, or comment prompt) is included.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Paywall placement follows the Tease &amp; Convert model (not a mid-sentence cut).</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Welcome email customization is recommended if the post is the first in a new publication.</li>\n</ul>\n","files":[{"path":"references/formatting-best-practices.md","sizeBytes":1801,"isText":true},{"path":"references/seo-output-example.md","sizeBytes":1403,"isText":true},{"path":"SKILL.md","sizeBytes":4196,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
