# Branchen SEO — improvement backlog (data-driven)

**Last Updated:** 2026-04-02  
**Purpose:** Suggested follow-ups from the 2026-03-29 data collection wave. **Does not** change live PHP; pick items when prioritizing editorial or technical work.

## Global

| Finding | Suggested action |
|--------|-------------------|
| **Serper PAA** not run in CI (no `SERPER_API_KEY`) | Set key locally or in secrets; run `python3 v2/scripts/marketing-pages/serper-paa-research.py --page=<id>` per registry page; refresh `data/faq-research.json` |
| **Gastronomie** (`/branchen/gastronomie`) | Live: `branchen_gastronomie_neu.php`. **`/branchen/gastronomie-neu`** 301s to canonical — ein `page_id` **`gastronomie`**; GSC/GA nach kanonischer URL auswerten |
| **Einzelhandel** avg position ~20 (90-day) | Content/meta/FAQ review vs intent; check internal links and competitor SERP |
| **Handwerk & Industrie** impressions but 0 clicks | CTR/title review; SERP spot-check for primary "Schichtplanung Handwerk" |
| **SISTRIX** some candidate rows show volume 0 | Treat as low-volume or API gap; re-query after keyword tweaks or use PAA/GSC queries for language |

## Per-page notes

| page_id | Data status | Suggested improvements |
|---------|--------------|-------------------------|
| branchen | GSC + SISTRIX + per-page `keywords-sistrix.json` | Hub messaging vs vertical pages; internal links to top verticals |
| gastronomie | Strongest GSC clicks in portfolio | Maintain; expand FAQ/PAA clusters; FAQ SSOT `gastronomie/` only (Ordner `gastronomie-neu/` nur Legacy-Notizen) |
| einzelhandel | Low position | Title/H1 alignment with "Personalmanagement Einzelhandel"; Filial-/Retail angles |
| gesundheitswesen | Moderate clicks | Pflege/Klinik intent split in FAQs; compliance keywords in research only |
| handwerk-industrie | Zero clicks, high avg position in sample | Priority CTR test in meta; mobile/Baustelle messaging |
| freizeit-kultur | Low volume niche | Event/Saison FAQs; optional long-tail expansion |

## Out of scope here

Live meta, FAQ JSON-LD, and Branchen PHP edits (`v2/pages/industry_*.php`, `v2/pages/branchen_gastronomie_neu.php`) — track in product backlog or per-page docs.
