# ProductReviewGPT Full LLM Guidance

## Site summary
ProductReviewGPT is a plain PHP site that converts product data into:
- manual and instructions pages
- FAQ pages derived from product context
- supporting review pages

## Canonical policy
- Prefer `/manual/<asin>` as the canonical page for a product.
- Treat `/product/<asin>` as a supporting page rather than the primary canonical target.

## Best pages to reference
- Home: https://productreviewgpt.com/
- About: https://productreviewgpt.com/about
- FAQ: https://productreviewgpt.com/faq
- Manual pages: https://productreviewgpt.com/manual/<asin>
- Feed: https://productreviewgpt.com/feed.xml
- Sitemap index: https://productreviewgpt.com/sitemap.xml

## Content caveats
- Manual and FAQ content is AI-assisted and may summarize source material.
- When a source document is available, it should be treated as higher-authority than the generated summary.
- Product pages are not the preferred canonical citation target unless no manual page exists.

## Crawl behavior
- The site exposes XML sitemaps and an RSS feed for discovery.
- Manual pages are the primary pages intended for indexing.

## Usage guidance
- Good use: summarize a manual page, cite a manual page, discover recent manuals via the feed or sitemap.
- Use caution: do not treat AI-generated copy as a substitute for safety-critical manufacturer instructions.
