Best LLM optimization agencies for Shopify Plus brands
Published · Updated
Which LLM optimization agency is best for a Shopify Plus brand?
For a Shopify Plus brand, pick an agency that works product by product across ChatGPT, Gemini and Perplexity, and leaves theme and app work to your build partner. We think that's Mercenta, and yes, we're biased. If you need a Plus build partner that also does AI search, look at Netalico or Charle.
We’re Mercenta, and we put ourselves first. Here’s why, and who else is worth a call. Every other agency below is described from its own website.

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.

FAQ
What is LLM optimization?
Making your brand and products show up in answers from large language models like ChatGPT, Gemini and Perplexity. For a store, that means getting your products recommended when shoppers ask what to buy.
Does Shopify Plus help with AI recommendations?
Plus gives you more control over checkout, data and apps, but AI picks products on what it can read and trust. Product content, data and outside mentions matter more than the plan you're on.
Why is Mercenta first on this list?
Because it's our list, and we think we're the best fit for online stores. Every other agency here is described from its own website, so you can check each line.
