Generating Lanthome SEO Blogs

Overview

Create a complete Lanthome B2B skincare SEO package from one product page. Keep every claim traceable to the source page and deliver files that are ready for editorial review.

Content Direction Rotation (8-direction cycle)

To avoid repetitive content, each blog rotates through 8 content directions. Determine which direction to use by counting the number of articles already generated (from blog-generation-history.json used_product_urls length) and applying modulo 8:

Index	Direction	Title Formula	Core Content Focus
0	Selection Decision	Should You Launch [Product]? Market Size & Margin Analysis	Market size, profit margin, competition, entry barriers
1	Ingredient Science	[Ingredient] in Skincare: What Brands Need to Know	Ingredient mechanism, regulation limits, concentration, compatibility
2	Supplier Comparison	How to Evaluate [Product] Manufacturers: 7-Point Checklist	Evaluation dimensions (certs, MOQ, sampling, lead time, stability, comms, compliance)
3	Formulation Deep-Dive	[Product] Formulation Guide: Actives, pH & Stability	Active selection logic, pH range, preservative system, stability testing
4	Packaging & Compliance	[Product] Packaging & Labeling: EU/US/FDA Requirements	Label regulations, packaging materials, shipping restrictions, eco-packaging
5	Cost & Pricing	[Product] OEM Cost Breakdown: MOQ, Unit Price & Margin	Cost structure (ingredients + packaging + labor + certification + logistics), MOQ pricing tiers
6	Trend & Seasonal	2026 Skincare Trends: What to Source for [Product Category]	K-beauty trends, seasonal positioning, social media data
7	Launch Playbook	From Concept to Shelf: Launching a [Product] in 90 Days	Timeline: selection → sampling → revision → production → QC → logistics → launch

Each direction produces structurally distinct content — different H2 sections, different tables, different FAQ questions. Do NOT use the same H2 structure across directions.

Workflow

1. Validate that the source is a lanthomeskincare.com product URL and inspect the live page.
2. Extract supported product facts and existing online product image URLs.
3. Read blog-generation-history.json to count used_product_urls length. Calculate direction_index = length % 8. Use the matching direction from the rotation table above.
4. Choose a buyer-oriented OEM/private-label primary keyword matching the selected direction. Ensure the primary keyword does NOT overlap with other articles' primary keywords.
5. Read references/output-spec.md completely, then draft the metadata and English article following these rules:
   • SEO Title: 50–65 characters, follow the title formula from the selected direction.
   • Meta Description: 140–160 characters with benefit + CTA.
   • SEO Keywords: 3–5 phrases, no keyword overlap across articles.
   • Breadcrumb: Home > Blog > Article Topic (no repetition).
   • Introduction: 2–4 sentences stating reader's problem and key conclusion upfront.
   • Table of Contents after introduction with clickable anchor links to each H2.
   • Short paragraphs (2–4 sentences), lists, and tables.
   • At least 2–3 product-specific details (anti-template requirement).
   • Conservative efficacy language (no "cures", "heals", "clinically proven").
   • 2–5 authoritative sources cited for ingredient/regulation content.
   • At least 5 internal links with descriptive anchor text.
   • Author info block before CTA button.
   • H2 sections MUST match the selected direction's content focus, NOT the generic "Market → Formula → Packaging → QC → Launch" structure.
6. Build the editor-ready fragment from assets/blog-fragment-template.html — include TOC, author block, and CTA button.
7. Use the imagegen skill to create the landscape PNG cover. The cover must include the article headline text (SEO title or H1) overlaid on the image.
8. Run every completion check in the reference before reporting the files.

Inputs

• Require one Lanthome product URL.
• Accept an optional primary keyword, article angle, or additional internal links.
• If the page is inaccessible, request product-page content or an export instead of guessing.

Output Files

Create a unique slug-based directory containing:

• <slug>.md
• <slug>-blog-editor.html
• <slug>-cover.png

The article body must exceed 2,000 English words. Include the author lanthomes-elian, related links matching the product's category (product + relevant category + About Us + Contact Us), SEO metadata, custom URL, and breadcrumb.

Source and Safety Rules

Use only facts supported by the live product page. Use cosmetic, buyer-oriented language. Do not invent medical efficacy, certifications, regulatory status, test results, quantities, lead times, ingredients, or manufacturing capabilities.

Completion

Return the three file paths and a short validation summary. Generate files only: do not access UEESHOP, fill publishing forms, save drafts, or publish.

UEESHOP Blog Editor Injection (for automation tasks)

The UEESHOP blog editor uses TinyMCE in iframe mode (Content_ifr). Setting textarea.value does NOT persist — TinyMCE reads from its own internal model on save. The source code modal approach also fails because the modal's OK button click times out.

Correct injection method — use TinyMCE API + triggerSave:

js

(function(){
  var html = `...FULL HTML BODY...`;
  var ed = tinymce.get('Content');
  if (!ed) ed = tinymce.activeEditor;
  if (!ed) return 'No TinyMCE editor found';
  ed.setContent(html);
  ed.save();
  tinymce.triggerSave();
  var ta = document.getElementById('Content');
  return 'Content set. TinyMCE=' + ed.getContent().length + ' | Textarea=' + (ta ? ta.value.length : 'no ta');
})()

CRITICAL: ed.setContent() alone does NOT persist on form submit. TinyMCE keeps content in its own iframe model and does NOT auto-sync to the hidden textarea. MUST call ed.save() AND tinymce.triggerSave() after setContent.

MANDATORY verification — run a SECOND console call after injection:

js

(function(){
  var ed = tinymce.get('Content');
  var len = ed ? ed.getContent().length : 0;
  if (len < 500) return 'WARNING: Content length = ' + len + ' — retry injection!';
  return 'VERIFIED: Content length = ' + len;
})()

If content < 500 chars: retry injection. Do NOT save until verified.

Post-save verification — reopen the draft and confirm content persisted:

js

(function(){
  var ed = tinymce.get('Content');
  var len = ed ? ed.getContent().length : 0;
  return len > 500 ? 'PERSISTED: ' + len + ' chars' : 'EMPTY: body not saved!';
})()

If EMPTY after save: content was lost during save — re-inject and re-save.

Do NOT use: textarea.value alone, source code modal, or setContent without triggerSave.

TinyMCE editor IDs on this page: Content (main body), MobileDescription (mobile description). Always target Content for the article body.

SEO Keywords: Do NOT fill the SEO keywords field in the UEESHOP form. Keywords are generated for the .md metadata only.
