Rule: Mergado Pilot#

Mergado Pilot is a set of AI rules that improve the content of your feed in bulk. It currently offers three types:

• Title and description improvement — rewrites or enriches the product title (Title) or product description (Description).
• Q&A (question and answer) — generates question/answer pairs for Google Shopping and ChatGPT (OpenAI Shopping).
• Product highlight — generates key product features for Google Shopping.

Mergado Pilot is only available in Canvas (the new interface) — you will not find it in the classic interface.

Available rules by output format#

The availability of each type depends on the output format of your project. An unsupported type will appear in the list but cannot be selected.

Activation and access#

When adding a new rule, select Mergado Pilot as the rule type. A list of available Pilot rule types will appear — select the one you want to use and continue through the setup wizard.

Important: AI processing takes longer#

AI text processing runs asynchronously — in the background, outside the regular feed regeneration process. This means that changes may not be available after the first feed regeneration. The AI is still finishing processing the products.

Wait for Mergado to regenerate the feed again (or regenerate it manually) — only then will the AI results appear in the output. For large catalogues, you may need to regenerate the feed multiple times.

Important: Mergado Pilot modifies data only in the feed. Products in your online store remain unchanged.

Rule: Title and description improvement#

Typical use cases:

• Optimising product titles for Google Shopping, Heureka, or Meta
• Rewriting descriptions for a specific market or language
• Adding missing information to descriptions based on feed data
• Unifying the tone of communication across your product catalogue

How the rule works#

The rule iterates through products from the selected queries and sends each product’s feed data along with your instruction to the AI. The AI returns the modified text, which Mergado writes to the target element (Title or Description) — just like any other rule.

Results depend on the quality of the data in your feed and how precise your instruction is.

Creating the rule#

The rule is created using a 4-step wizard.

Step 1 – Queries#

Choose which products the rule should apply to:

• All products — the rule updates the element (title or description) for all products in the project.
• Custom query — the rule applies only to products from the selected product query. You can select an existing query or create a new one directly in this step.

Step 2 – Element#

Select whether you want to update the product title or product description:

• Product title — a short title optimised for advertising. Mergado Pilot will update the element containing the product title (e.g. PRODUCTNAME or g:title).
• Product description — a longer text describing the product. Mergado Pilot will update the element containing the product description (e.g. DESCRIPTION or g:description).

A single rule run updates only one element at a time. To update both the title and description, create two separate rules.

Step 3 – Prompt#

Enter the instruction that tells the AI how to modify the text. There are two approaches:

a. Preset style:

Choose one of three styles — Mergado Pilot uses a prepared system prompt optimised for that tone:

• Factual and informative — precise, structured texts. Suitable for technical products.
• Friendly and clear — natural language for everyday customers. Suitable for fashion, food, gifts.
• Energetic and compelling — emotional, sales-driven tone. Suitable for promotions, new arrivals, premium goods.

System prompts are also tailored to the target output format of your project (Google Shopping, Heureka, Meta, and others). For example, if you are working on a Google Shopping output, the AI automatically takes into account Google Merchant Center recommendations and guidelines — without you having to specify them explicitly.

b. Custom prompt:

Write any instruction for the AI. For example:

• “Rewrite the product title in the format: Brand + Name + Colour + Material. Maximum 150 characters. Use only product data.”
• “Add key product features suitable for Google Shopping to the description. Use only data from the feed.”

Strict mode:

This step also lets you enable strict mode. When enabled, the AI does not add information that is not directly present in the feed data. Outputs are more accurate but may be shorter. When disabled, the AI can naturally expand and enrich the text.

When to use strict mode: Enable it when you want to make sure the AI does not invent parameters, colours, or attributes that are not in the feed. Especially useful for technical products or any catalogue where data accuracy matters.

Step 4 – Name#

Enter the rule name that identifies it in the project’s rule list.

Tip: Before applying the rule to your entire catalogue, test it on a smaller product query first. Review the results in the product preview, then expand the query to the full catalogue.

Examples#

Example 1 — Optimising titles for Google Shopping#

A clothing online store wants to add brand, colour, and material to product titles to meet Google Merchant Center recommendations.

1. Create a new rule → type Mergado Pilot → Title and description improvement.
2. Queries: All products (or a query for a specific category).
3. Element: Product title.
4. Prompt: Custom — “Rewrite the product title in the format: Brand + Name + Colour + Material. Maximum 150 characters. Use only product data.”
5. Strict mode: On.
6. Save the rule and apply it. Results will appear in the feed after regeneration.

Example 2 — Friendly description for Heureka#

An online store wants product descriptions on Heureka to be readable and easy to understand for everyday customers — not just a technical list of specifications.

1. Create a new rule → type Mergado Pilot → Title and description improvement.
2. Queries: All products (or a query for a specific category).
3. Element: Product description.
4. Prompt: Preset style — Friendly and clear.
5. Strict mode: Off — the AI can naturally enrich the text.
6. Save the rule and apply it. Results will appear in the feed after regeneration.

Rule: Q&A (question and answer)#

The rule automatically generates the content of the g:question_and_answer element for Google Shopping (or the corresponding element for ChatGPT/OpenAI Shopping). The element contains question/answer pairs that can help customers make a purchase decision.

The data source is currently the product feed only, primarily the product description. Processing runs using an LLM on Mergado’s servers — data does not leave its infrastructure.

💡 Integration with reviews from Mergado Depots (Heureka, Zboží.cz) as an additional data source is in preparation and is not yet part of this rule.

Creating the rule#

The Q&A rule has a simple setup with just two steps:

1. Queries — choose which products the rule should apply to (all products, or a custom query).
2. Name — give the rule a name.

The number of generated question/answer pairs is determined automatically by the rule — it cannot be set manually.

Example#

An electronics online store wants to answer common customer questions directly in Google Shopping or ChatGPT before purchase (e.g. “Does the headset have wireless volume control?”). Simply create a Q&A rule for a selected product category — Pilot will automatically generate the corresponding question/answer pairs from the product description.

Rule: Product highlight#

The rule automatically generates the content of the g:product_highlight element for Google Shopping — the element records key product features and can appear multiple times for a single product.

The data source is the product description. Processing runs using an LLM on Mergado’s servers — data does not leave its infrastructure.

⚠️ This rule is currently only available for the Google Shopping format — for ChatGPT (OpenAI Shopping), the corresponding element does not yet exist.

Creating the rule#

Like Q&A, the Product highlight rule has just two steps:

1. Queries — choose which products the rule should apply to.
2. Name — give the rule a name.

Example#

A fashion online store wants to highlight key product features in Google Shopping (e.g. “Waterproof material”, “Handmade”) without having to write them manually for each product. The Product highlight rule generates them automatically from the product description.

FAQ#

What is the difference between Mergado Pilot and the Rewrite rule?#

The Rewrite rule writes exactly the text or variable you specify — the result is always the same for all products. Mergado Pilot sends each product’s data to the AI, which generates unique content for each product based on your instruction (or automatically for Q&A and Product highlight). Use it when you need content tailored to individual products.

How many products does the rule process at once?#

The rule processes all products from the selected query sequentially. Processing a large catalogue takes longer. The AI generates content for each product individually, and results are written to the feed asynchronously once complete. You may therefore need to regenerate the feed several times.

Can I create a separate rule for the title and the description in one project?#

Yes. Create two separate Title and description improvement rules, each for a different element. One will update the product title, the other the product description.

What if the AI output does not meet my expectations?#

For the Title and description improvement rule, edit the prompt or toggle strict mode and run the rule application again. For Q&A and Product highlight rules, custom settings cannot yet be adjusted. We recommend testing on a smaller product query first.

Does Mergado Pilot affect the order of other rules?#

Yes. AI rules behave like standard rules, and their position in the rule order affects what data the AI receives as input and how subsequent rules can modify it. If you want the AI to work with values already modified by other rules, place Mergado Pilot after them.

How can I check what the AI rule changed for a specific product?#

Use the Rule trace feature — it shows how the element value changes after each rule is applied, including the AI rule.

Can I enable and disable the rule without deleting it?#

Yes. The rule can be paused just like any other rule type. Products will remain unchanged until you activate the rule again.

What is strict mode and which rule has it?#

Strict mode is available for the Title and description improvement rule. It tells the AI to rely only on the product data in the feed and not to add information that is not there. Enable it when accuracy matters — for example, for technical products where you do not want the AI to invent a colour or specification.

Why does Q&A or Product highlight not appear for my project?#

These rules are only available for certain output formats — Q&A for Google Shopping and ChatGPT, Product highlight for Google Shopping only. For an unsupported format, the rule will appear in the list as unavailable.

Can I set a custom prompt or style for Q&A or Product highlight?#

Not yet. Unlike the Title and description improvement rule, these generate content automatically, without the option to set a custom prompt or choose a style.

Where do the Q&A and Product highlight rules get their data from?#

Currently exclusively from the product feed, primarily from the product description. Integration with reviews from Mergado Depots (Heureka, Zboží.cz) is being prepared for a future version.

Is the content sent to the AI protected?#

Product data (title, description, and any parameters) is sent to an AI model for the purpose of generating content. The data is not stored for model training. For Q&A and Product highlight rules, processing runs on Mergado’s servers, so data does not leave its infrastructure. The system prompt that governs the AI’s basic behaviour is managed by Mergado and cannot be edited directly by the user.
