# BRIEF v2 — Home page advmfr.com — RESTART, full SEO discipline You are a senior B2B SEO content strategist + technical writer. The previous draft (v1) failed to respect the Lumenia brief, n-gram densities and word-count target. This is v2: write the COMPLETE markdown for the new home page of advmfr.com. This page must rank #1 in UK on `jewellery manufacturing` (KD 8, vol 2 600/mo) AND beat the current SERP competitors on E-E-A-T, depth, and structure. **Output: ONLY the final markdown file content. Start with `---` (frontmatter), end with the last JSON-LD closing fence. No preamble, no explanation, no commentary, no "Here is..." preface.** --- ## 1. NON-NEGOTIABLE TARGETS | Target | Value | Why | |---|---|---| | Body word count (excl. frontmatter + schema) | **1 950 – 2 100 words** | SERP average is 2 000–3 500. Going under = Google judges page thin. | | H1 count | exactly 1 | One topic per page | | H2 count | **8 to 10** | Matches competitor depth (Whiteflash = 8 H2) | | H3 count | **12 to 18** | Drives scannability + featured snippet eligibility | | Primary keyword `jewellery manufacturing` density | **8–12 occurrences** in body (~0.5%) | Strong signal without stuffing | | 2-grams from Lumenia | **at least 8 out of top 10** used naturally | Cluster coverage | | 3-grams from Lumenia | **at least 4 out of top 10** used naturally | Long-tail capture | | Top 50 Lumenia terms | **at least 35 out of 50** appear in body | Topical coverage | | Internal links | **9 mandatory anchors (see §6)** + 2 optional | Architecture pass-through | | Schema blocks at end | **4** (Organization, LocalBusiness, FAQPage, BreadcrumbList) | Maximise SERP surface | | Image placeholders | **minimum 8** as `IMAGE_PLACEHOLDER_.jpg` with descriptive alt | Match competitor visual density | --- ## 2. COMPANY FACTS (immutable — use only these — never invent) - **Brand**: Advance Manufacturers (ADVMFR) — `advmfr.com` - **Type**: B2B fine jewellery manufacturer (services: OEM, ODM, private label, wholesale) — but DO NOT use the words OEM/ODM/private label in H1, title or meta - **Founded**: 1989, originally a joint venture with **Friedrich Zettl GmbH** (Pforzheim, Germany). Keep this German-Thai heritage mention — it's a real EEAT signal. - **Family-run** business, 30+ years - **400+ employees**, many with 20–30 years tenure - **3 000 000+ pieces** per year production capacity - **Factory**: Bangkok, Thailand (geo 13.778318, 100.787995) - **Metals worked**: 8k, 9k, 10k, 14k, 18k gold; 925 sterling silver; brass - **Stones used**: precious and semi-precious gemstones, natural diamonds, lab-grown diamonds, cubic zirconia, crystals, mother of pearl, pearl, enamel - **Sustainability claims permitted**: recycled metals, conflict-free gemstones, biodegradable packaging - **Certification**: RJC certified - **Categories produced**: earrings, pendants, necklaces, bracelets, rings, chains, hoops, sets - **In-house capabilities**: design, CAD/CAM, 3D printing of master models, wax injection, lost-wax casting, assembly, stone setting, soldering, laser welding, plating (rhodium, gold), polishing, enamelling, QC, custom packaging **For unknown specifics (exact MOQ, lead time, payment terms): use literal `[CONFIRM WITH ADVMFR]` — do NOT invent numbers.** --- ## 3. KEYWORD STRATEGY (strict vocabulary boundary) ### 3.1 Primary keyword - `jewellery manufacturing` — KD 8, vol 2 600/mo. Must appear in: TITLE, META, H1, AT LEAST 8 times in body. ### 3.2 Secondary keywords (this page also captures naturally) - `jewellery manufacturer` (KD 22, vol 2 600) — natural human phrasing; H1, H2, body - `jewellery manufacturing process` (informational long-tail) — H2 of process section - `fine jewellery manufacturer` — body - `bangkok jewellery manufacturer` / `jewellery manufacturer in thailand` — body (geographic capture) ### 3.3 FORBIDDEN in H1 / Title / Meta (cannibalisation rule — these belong to OTHER pages) - `wholesale supplier`, `wholesale jewellery supplier` → /wholesale-suppliers/ — REMOVE from current title; may appear once in body with link - `OEM`, `ODM`, `private label`, `white label`, `contract manufacturer` → /oem-jewellery-manufacturer/ — body OK once with link, NEVER in H1/Title/Meta - `custom jewellery design`, `jewellery design service`, `CAD design service` → /design-development/ — body OK once with link - `RJC certified jewellery manufacturer` (as exact phrase) → /sustainability/ — body may say "RJC certified" only - `jewellery manufacturer thailand` (as exact-match H1) → /about-us/ — body mention OK - `jewellery findings`, `bulk jewellery`, `MOQ jewellery` → /wholesale-suppliers/ — avoid ### 3.4 NEVER on this page (regulatory / blog territory) - `Fairmined gold` — ADVMFR not certified Fairmined - `Fairtrade gold` — ADVMFR not certified Fairtrade - `Kimberley Process` — blog topic only - `Responsible Jewellery Council` (expanded phrase) — say "RJC certified" only on this page ### 3.5 Language - UK English systematic in H1, title, meta, URL, headings, body - Permitted UK→US natural variants in body (1–2× max): `jewelry`, `jeweler` - Spelling rules: `jewellery`, `colour`, `centre`, `customise`, `programme`, `analyse`, `optimise`, `specialise` --- ## 4.

You MAY use these technical/generic terms: Rhodium Plating, Computer Aided Manufacture, Vulcanizing, Computer Aided Designing, Japan, China (only as geographic comparison if needed, otherwise skip). --- ## 5. COMPETITOR SERP ANALYSIS — what we must match + beat We scraped the top 5 ranking pages for `jewellery manufacturing`. Synthesis of their structure: ### 5.1 Whiteflash (whiteflash.com) — gold-standard educational page, ~3 220 words, 8 H2 H1: Jewelry Manufacturing Byline: By Bryan Boyne (g.g.) ← Graduate Gemologist (EEAT signal — we'll do the equivalent) Intro: history (thousands of years) → modern focus Topics index (8 anchor links) H2: CAD/CAM H2: Lost Wax Casting H2: Fabrication H2: Hand Forged Jewelry H2: Laser Welding H2: Stone Setting H2: Ring Sizing H2: Finishing **Lesson:** they win because they cover modern techniques (laser welding, CAD/CAM) AND ancient ones (lost wax, hand forging) — full topical breadth. ### 5.2 Kosh (koshjewellery.com) — process page, ~2 045 words, 12 Steps 12 Steps as styled H2: 1 Designing, 2 CAD/CAM, 3 Model Making, 4 Rubber Mould, 5 Waxing/Wax Tree, 6 Casting, 7 Grinding, 8 Filing/Assembly/Pre-polishing, 9 Metal Setting, 10 Polishing, 11 Rhodium Plating, 12 Quality Control **Lesson:** numbered step structure works for procedural intent. We'll use a similar (but shorter, 8-step) numbered process H2 with H3 per step. ### 5.3 Jewelry Touch (jewelrytouch.com) — process page, ~3 532 words, 11 numbered steps Steps include lost wax casting + tree wax + assembly + pre-polish + setting + stone cutting + final polishing. **Lesson:** confirms numbered step format dominates. ### 5.4 Empire Casting House — step-by-step, ~1 165 words, 13 H3 steps H3 steps: Idea Generation, CAD Design, Printing, Casting, Tumbling, Jeweler's Touch, Pre-Polishing, Provide Diamond, Setting, Polishing, Quality Control, Photo and Render, Ready Pickup. **Lesson:** shorter but very granular H3 — boosts featured snippet eligibility. ### 5.5 Riva Precision (rivaprecision.com) — B2B chains manufacturer homepage, ~2 729 words E-commerce style with hero + product category cards + USP strip (Brooklyn Based, Free Shipping, Chat With Us). Includes "Fairmined Gold" in product names — we cannot copy this. **Lesson:** the B2B angle wins with USP strip + product categories + trust signals. Our advantage: vertical integration + 30+ years + 3M pieces/year (Riva is smaller). ### 5.6 Our differentiation strategy vs SERP | Competitor | What they do | What we do better | |---|---|---| | Whiteflash | Educational depth but they are a retailer with an article | We are a real manufacturer — process page = our actual factory operations | | Kosh | Process steps with images, but no scale credibility | We add 3M pieces/year + 400 craftspeople + RJC | | Jewelry Touch | Long process explainer | We add B2B CTAs + internal links to other commercial pages | | Empire Casting | Granular steps | We add EEAT (1989, German JV, named heritage) | | Riva Precision | B2B + e-commerce | We add educational depth that Riva lacks | **Our unique angle:** a homepage that ranks #1 informational AND converts B2B leads because it combines factual process depth (Whiteflash-grade) + real manufacturer authority (we ARE the factory). --- ## 6. MANDATORY INTERNAL LINKS (exact anchor text required) | Anchor text (EXACT) | Target URL | |---|---| | OEM, ODM & private label service | /oem-jewellery-manufacturer/ | | wholesale jewellery supplier | /wholesale-suppliers/ | | in-house design & development team | /design-development/ | | see our full production process | /production-process/ | | RJC certified ethical manufacturing | /sustainability/ | | learn more about us | /about-us/ | | discuss your project | /contact-us/ | | browse our jewellery categories | /categories/ | | trade fairs & industry events | /news-events/ | Optional secondary anchors (add if natural): - `lost wax casting` → /production-process/lost-wax-casting/ - `jewellery plating` → /production-process/jewellery-plating/ - `jewellery polishing` → /production-process/jewellery-polishing/ --- ## 7.
