## Guides

- [How to track ChatGPT Ads conversions on Shopify: pixel and Conversions API, step by step](https://convrail.com/blog/track-chatgpt-ads-conversions-shopify/): Register the OAIQ pixel as a Shopify web pixel, send order_created from your server with the same event ID, hash emails and test with validate_only.
- [The OpenAI product feed specification, explained field by field (with rejection examples)](https://convrail.com/blog/openai-product-feed-spec-explained/): The OpenAI product feed has 9 required fields, strict money and boolean formats and legacy aliases. Every rule with a valid and a rejected example.
- [OAIQ pixel vs Conversions API: why ChatGPT Ads tracking needs both layers](https://convrail.com/blog/oaiq-pixel-vs-conversions-api/): The OAIQ pixel sees the click context, the Conversions API sees every paid order. Send both with one shared event ID and OpenAI keeps a single copy.
- [Why your products do not show up in ChatGPT shopping results: a 10-point checklist](https://convrail.com/blog/products-not-showing-chatgpt-shopping/): Products missing from ChatGPT shopping usually trace to a malformed feed row. Ten causes, from a bad price format to a stale snapshot, and how to fix each.
- [ChatGPT Ads conversion optimization: your conversion data now trains the bidding](https://convrail.com/blog/chatgpt-ads-ocpc/): oCPC campaigns optimize toward one tracked conversion event, so duplicates, missing orders and late events distort bids. How to keep the signal clean.
- [Shopify orders with ChatGPT as the source: how to read that label](https://convrail.com/blog/shopify-order-source-chatgpt/): Shopify derives an order's source from the visit's referrer and landing page. What that proves, why it goes missing by checkout, and how to reconcile it.
- [Parquet vs JSONL vs CSV for OpenAI product feeds: what actually matters](https://convrail.com/blog/parquet-vs-jsonl-vs-csv-openai-feed/): OpenAI accepts parquet (preferred, with zstd), jsonl.gz, csv.gz and tsv.gz. The format decides how booleans, identifiers and nested fields survive export.

- [ChatGPT organic vs ChatGPT Ads: measuring two channels in one](https://convrail.com/blog/chatgpt-organic-vs-ads-attribution/): ChatGPT sends shoppers via organic product results or paid ads. How to split the two with oppref, UTMs and referrers, and compute ROAS honestly.
- [Google Shopping feed vs OpenAI product feed: what transfers, what breaks](https://convrail.com/blog/google-shopping-feed-vs-openai-feed/): Most Google Shopping columns map to the OpenAI feed; seller_name, eligibility flags, target_countries and pre_order do not. Mapping table and fixes.
- [From prompt to purchase: what an AI-native buying journey looks like in your analytics](https://convrail.com/blog/prompt-to-purchase-ai-buying-journey/): A ChatGPT purchase writes a chain of records: feed row, click with oppref or referrer, pixel events mirrored by a server event, attributed order.
