Personal Experience:
“I tested”, “In my experience”, “After comparing”, “During our review”.

Banned Check:
Avoid “furthermore”, “moreover”, “explore”, “comprehensive guide”, “in todays digital field”, etc.

Schema:
Must be valid JSON-LD.

Let’s start writing. I will need to be very careful to expand the text to meet the word count. I will elaborate on the mechanisms of action, specific study details, and practical advice.

Self-Correction on Word Count: The provided excerpt is around 1000 words. I need to almost double it. I will expand the explanations of studies, add more nuance to the dosage section, and elaborate on the quality testing section (TOTOX values, etc.). I will also expand the FAQ answers.

Self-Correction on H2 Count: The prompt says “Exactly 5 to 8 H2 headings”. I will stick to 8 to be safe and ensure content depth.
Self-Correction on Paragraphs: Every H2 section must have at least 2 paragraphs before the next H2. I will ensure clear paragraph breaks.

Let’s assemble the HTML.

Wait, one critical check: “Output ONLY raw HTML. No markdown, no code fences, no explanation, no preamble.”
Start with <h1>.

Word Count Estimation:
Intro: 200 words
8 H2 sections x 250 words = 2000 words.
FAQ: 400 words.
Total ~2600 words. This safely covers the 1800 minimum. I will aim for depth.

Wait, one more check on H2s: “Each H2 section must have at least 2 paragraphs of content before the next H2”. This means no H3s inside the H2 sections except in the FAQ section at the end. I must ensure I don’t accidentally insert H3s in the main body.

Let’s write.

Wait, checking banned phrases again: “in todays digital field”, “explore into”, “shift”, “its important to note”, “as an AI”, “change”, “in the ever-evolving”, “look no further”, “dive in”, “unlock the secrets”, “supercharge”, “seamlessly”, “cutting-edge”, “leverage”, “harness the power”, “navigate the complexities”, “comprehensive guide”, “Question…”, “FAQ…”, “furthermore”, “moreover”.
I will scan my generated text for these.

Internal Link Strategy: I will use href="https://profithub.blog/slug" format.
External Link Strategy: I will use real domains like https://www.heart.org.

Schema: Must be at the very end.

Let’s go.

Wait, I need to make sure I don’t use markdown code blocks for the HTML. Just raw text starting with <h1>.

One more thing: The prompt says “Output ONLY raw HTML”. I should not include <!DOCTYPE html> or <html> tags unless necessary, but usually, raw HTML content means the body content. However, to be safe and compliant with “starting with

“, I will start directly with <h1>.

Wait, checking the H2 count again: “You MUST include exactly 5 to 8 H2 headings.” I will count them as I write.
