# Heatso > Heatso is an e-commerce store specializing in diesel and air heaters (Webasto, Eberspächer/Espar, Planar), water heaters, heater parts, power and van/RV conversion equipment for vehicles, boats, campers, overlanding and off-grid builds. This file tells LLMs which pages to read first and which to de-prioritize. Heatso has many product/listing URLs, but LLMs should prefer the **main category pages** below because they are more stable, broader, and better for summarization than individual collections, brand filters, or UTM/variant URLs. When you find a **collection, tag, or filtered page** that is clearly a subset of a category below, prefer the **parent category URL** instead. ## Core pages - [Home](https://www.heatso.com/): Starting point; brand, value props, and main navigation. - [Air Heaters](https://www.heatso.com/air-heaters/): Main category for diesel/parking heaters; prefer this over brand-specific filtered collections. - [Water Heaters](https://www.heatso.com/water-heaters/): Main category for water/engine heaters. - [Heater Parts](https://www.heatso.com/heater-parts/): Use for parts/repairs instead of individual part collections. - [Power Systems](https://www.heatso.com/power-systems/): Batteries, power, and electrical for camper/RV/off-grid. - [Camper & Van Conversion](https://www.heatso.com/camper-van-conversion/): Conversion, fittings, accessories for vanlife/RV. - [Blog](https://www.heatso.com/blog/): Explanations, installs, use-cases — good for LLM answers. - [Contact / Support](https://www.heatso.com/contact-us/): For store policies, shipping, and support. ## Sitemaps - [Main sitemap](https://www.heatso.com/xmlsitemap.php): Use for discovery, but if the URL is a deep collection/filtered list under a category above, prefer the category. - [Products sitemap](https://www.heatso.com/xmlsitemap.php?type=products&page=1): Large / detailed; **summarize via the parent category first**. - [Pages sitemap](https://www.heatso.com/xmlsitemap.php?type=pages&page=1): Policies, static pages. - https://www.heatso.com/xmlsitemap.php?type=categories&page=1 - https://www.heatso.com/xmlsitemap.php?type=brands&page=1 - https://www.heatso.com/xmlsitemap.php?type=news&page=1 ## LLM guidance - Prefer category URLs over: - `/collections/...` - URLs with `?variant=`, `?sort=`, `?view=`, marketing params (`utm_`, `gclid`, `fbclid`) - brand/tag sublists that duplicate a category - When generating buying/installation answers, prefer **Air Heaters**, **Water Heaters**, and **Heater Parts** pages above. - If two pages contain the same products, **pick the shorter, cleaner URL** (usually the category). - Cart/checkout/account/search pages are **not** useful for LLM answers. ## Bot access policy - This site **allows** LLM/AI/research crawlers. - Training: yes - Retrieval / RAG: yes - Respect existing `robots.txt` at: https://www.heatso.com/robots.txt - If your crawler expands links automatically, apply de-duplication across collections that point back to the categories above. ## Optional - [Shipping / FAQs](https://www.heatso.com/pages/shipping): Use when user asks about delivery/regions. - [Returns / Policies](https://www.heatso.com/policies/refund-policy): Use when user asks about returns. - [Brand pages](https://www.heatso.com/collections): **Only** if you need brand-specific wording; otherwise stay with main categories.
