GEMINI + OPTIMLISTER

Write Shopify product listings from Gemini.

Connect once and Gemini writes the Shopify listing for real Google SEO: a title and description built around the terms shoppers actually search, because a standalone Shopify store's traffic is Google traffic, not marketplace-internal search.

CONNECT IN THREE STEPS

Get your key. Every Optimlister plan has an API key, Free included - it lives in your account.
Add the connector. Custom connectors are a Gemini Spark feature - it needs a personal Google Account (not Workspace or school), US residency, being 18+, and Keep Activity turned on, so not every account has it yet. If you do: Settings & help, then Connected Apps, then Custom apps for Spark, then Add a custom app. Use the URL https://optimlister.ai/api/mcp with your key as a Bearer token.
Ask. That is the whole setup. Your first successful connect adds 10 credits to your balance.

Key lives at your account · full setup details on the Connect your AI page.

WHY CONNECT IT

Google is the search engine that matters

Shopify has no internal marketplace search to game - the keywords come from real Google search volumes, the same data source Shopify SEO actually depends on.

SEO title and meta description, not just product copy

Both the on-page copy and the fields Google itself reads are written together, so the two never say different things.

The other supported marketplaces

Once the Shopify version is right, ask for the Amazon, Etsy or eBay version of the same product in one message.

PASTE THIS TO START

Write my Shopify product listing for this product: <describe it>. Pull real Google search demand for the category, then write an SEO title and description built around it.

Questions

Does it publish straight to my Shopify store?

Not from inside the chat today - it writes the listing content for you to paste in, or to publish through your Shopify connection once that path is live on your account.

Does this cost extra on top of Gemini?

The MCP server and API key come with every Optimlister plan, including Free. Tool calls price exactly like the site: listings use your monthly listings, photos and video use credits at the same rates, and free tools stay free.

Is this official MCP?

Yes - Optimlister runs a standard MCP (Model Context Protocol) server over HTTP, the same open standard Gemini uses for all its connectors. One URL, one key, no extension to install.

Why does a Shopify listing need marketplace-style keyword work at all?

Because a standalone Shopify store lives or dies on Google SEO - there is no marketplace-internal search sending it traffic the way Amazon or Etsy do, so the on-page copy has to work as an SEO page as much as a product listing.

See it work

Three steps, and what each one actually produces - words, pictures and video.

Give it what you have

A listing, a link, a photo, a product name, or the email a marketplace just sent you.

It writes, draws and checks, per marketplace

Six different listings and the images to go with them, each to that marketplace's limits and rules, with measured keywords behind the words.

You publish; it keeps watching

Files, exact fields or one-click fill; then daily rank, price and listing-health watch.

One product, six listingsExample · bamboo cutting board · pictures made by Optimlister

Why each version differs: every card is written fresh to the rule printed on it - Amazon now uses a 75-character Item name plus 125-character Item Highlights and benefit bullets, Etsy uses buyer-friendly titles and up to 13 tags, eBay uses item specifics, and Walmart uses structured attributes. The meter under each title shows how much of that marketplace's title limit the example uses. Every asset here is a real generator output with its exact cost - see the receipts.
