# Diff notes — standard-window-sizes-in-canada-a-complete-guide-for-homeowners

## why_better

- Stops competing with winning sibling `standard-window-sizes.html` (+364 clicks) for broad “standard window sizes” / room-by-room charts.
- Retargets to **measuring + notation + standard vs custom** (primary KW: how to measure windows for replacement, CA vol 880).
- Removes invented dollar pricing table (SOP: no invented prices).
- Removes year from SEO title; sentence-case headings; no em dashes.
- Cross-links sibling twice for room charts; one soft link to `windows.html`.
- Keeps useful live S3 images (hero, install, custom, egress); drops type-gallery images tied to trimmed size charts.

## Cannibalisation / uniqueness

| Asset | Role after refresh |
|-------|--------------------|
| This URL | Measuring, notation, RO vs unit, when custom is needed |
| Sibling `standard-window-sizes.html` | Room-by-room + broad standard sizes (unchanged winner) |
| `windows.html` | Commercial hub — one soft contextual link only |

## Structure

**Major intent reframe (justified):** live competed for the same head as the sibling. Fractional keep of charts would continue cannibalisation.

| Live section | Action |
|--------------|--------|
| H1 / SEO title “Standard Window Sizes… 2026” | Replace with measuring-led title/H1 |
| Type size table + type-by-type galleries | **Cut** (sibling owns charts) |
| Room ideal-size table + bathroom/basement size FAQs | **Cut** / redirect to sibling |
| Cost / pricing spectrum table | **Cut** (unverified prices) |
| Metric vs imperial; custom when; Helen/Tony quotes; egress principles | **Keep / expand** |
| Rough opening FAQ seed | **Promote** to full section + measuring steps |
| Halifax windows link | **Remove** |

New spine:

1. Key takeaways  
2. How window sizes are written (notation + metric/imperial)  
3. Rough opening vs window size  
4. Replacement vs new construction  
5. How to measure (steps)  
6. When standard vs custom  
7. Code / egress (principles only)  
8. Mistakes  
9. FAQ (measure/custom focused)  
10. Soft CTA  

## Length

- Live ≈ **3,324** (charts + pricing inflate)  
- Refreshed ≈ **1,764** words (H1 → end of FAQ)  
- Target band **1,700–2,200** — PASS  

## Meta

- Title/H1/meta all changed (see `meta.yaml`).  
- Slug unchanged.

## Quotes

- Helen Sin + Tony Wong quotes retained from live (already published). Attribution formatting cleaned (no em dash). No new quote text invented.

## Fractional validation (CCW-adapted)

- Rewrite budget: **full intent reframe** documented above (not a patch) — required to clear cannibal fence.  
- Live in-body links: Helen/Tony about URLs preserved; types-of-windows → not required; Halifax removed; `windows.html` soft link kept; appointment CTA kept; **added** sibling links (fence).  
- Annotated review: real add/del clusters in `review-for-docs.html`.  
- Brand/SOP QA: see `qa-checklist.md`.
