How to pick
- Ecommerce only, or ecommerce as one of many? Each product has its own rivals and buying questions. An agency that only does stores knows that.
- Products, or just your brand? The sale is lost one product at a time, so the work should be done one product at a time.
- All the AIs, every week? ChatGPT, Gemini and Perplexity pick differently, and their answers change.
- No guarantees. Nobody controls AI. Walk away from anyone promising #1.
