4. **Drafting Content – Word Count & Constraints Check:**
* Need 1800+ words. This requires expanding significantly on the source text. I need to elaborate on mechanisms, study details, product specifics, and personal anecdotes.
* Need personal experience phrases: “I tested”, “In my experience”, “After comparing”, “During our review”.
* Need internal links (3-5): I will create plausible anchor text linking to other hypothetical pages on healthyprotricks.com (e.g., metabolism boosters, supplement reviews, protein guides).
* Need external citations (2+): NIH, Journal of Drugs in Dermatology, Nutrients Journal.
* Banned phrases check: Must avoid “comprehensive guide”, “delve into”, etc.
* H2 Check: Must be full questions. No truncation.
* H2 Content Check: At least 2 paragraphs per H2 section.
5. **Drafting – Section by Section (Mental or Scratchpad):**

6. **Word Count Strategy:**
* To hit 1800 words, I need to be verbose but valuable. I will expand on the scientific mechanisms, describe the sensory experience of the products (taste, texture), and elaborate on the safety warnings. I will ensure each paragraph is substantial (4-6 sentences).
7. **Reviewing Constraints:**
* NO markdown.
* NO code fences.
* RAW HTML only.
* Start with `
8. **Final Polish:**
* Ensure internal links look natural.
* Ensure external links point to real authorities (NIH, etc.).
* Verify personal experience phrases are included naturally.
* Verify word count estimation (I will write generously to ensure I meet the 1800 minimum).
*Self-Correction on Word Count:* Writing 1800 words in a single pass requires careful expansion. I will focus on detailing the *why* and *how* in every section. I will expand the product reviews to include more specific details about packaging, sourcing, and mixability based on the “I tested” perspective.
*Self-Correction on H2s:* Ensure no H2 is cut off. Ensure no “…” in headings.
*Self-Correction on Schema:* Must match the FAQ content exactly.
*Self-Correction on Banned Phrases:* I will scan for “comprehensive guide”, “delve into”, “moreover”, “furthermore”.
*Let’s start writing.*
*Wait, one more check:* The prompt says “Output ONLY raw HTML”. I must not include any text outside the HTML tags.
*Internal Links:* I need 3-5. I’ll place them in the intro, product section, and comparison section.
*External Links:* I need 2+. I’ll place them in the science sections.
*Let’s calculate rough word count per section:*
Intro: 200 words
H2_1: 250 words
H2_2: 250 words
H2_3: 250 words
H2_4: 400 words (5 products)
H2_5: 200 words
H2_6: 150 words
H2_7: 200 words
FAQ: 200 words
