What Is a Product in Mergado#

A product in Mergado is the basic data unit representing an item from your online store. Each product contains various elements that describe its properties – such as the name, price, or EAN. Mergado works with these products, modifies them, and optimizes them before exporting to advertising channels.

Products are made up of elements that define their properties (e.g., PRODUCTNAME, PRICE, EAN).
A feed is a file that contains all products and their elements.

Input and Output Data#

The entire process of working with products in Mergado is based on the transformation between two basic data sets – the input and output feed.

Elements in Mergado#

1. What are elements#

Definition#

An element is the basic building block of a feed that carries data. Each element represents a specific piece of information – for example, a product name, price, code, or image. In both XML and CSV, an element serves as a label for where a given value is located.

In simple terms:

element = “name of the information”,
value = “content of that information”.

I. Variables in Mergado Editor#

1. What are variables in Mergado#

Variables in Mergado Editor represent placeholders for specific values from elements. They are “holders” for data that differs from product to product and that you want to further process or use in rules.

A variable can have a different value for each product.
A typical example is the element PRICE_VAT, whose value changes across products.
You can create a variable manually – for example, if you need to extract part of the text from a name or description.
In addition to user variables, there are also special system variables, such as @MERGADO_ID.

Mergado works directly with elements as the source of values. Variables are a supplementary tool for situations where you need to extract only a specific part of a text or further process values.

Inverse queries in Mergado#

How to work with inverse queries in Mergado#

This article explains what inverse queries are and how to use them effectively in Mergado. We will show the difference between a simple inverse query (where you just change the operator, e.g. from “=” to “!=”) and a more advanced query using MQL and the NOT operator. By the end of this article, you will be able to:

Operators for Mergado Query Language#

List of operators in MQL#

This overview explains all operators you can use in Mergado Query Language (MQL) – a language for creating conditions in product queries. It will help you better understand how MQL works and how to formulate rules for selecting data precisely. With the correct use of operators, you will be able to create accurate, efficient, and well-organized queries.

`CONTAINS`	contains text

How does data regeneration and updating work in Mergado?

How does data regeneration and updating work in Mergado?#

Why it is important to regenerate data#

When you modify rules, filters, or queries in Mergado, or when the input data from your online store changes, it is important for these changes to actually make it into the output feed that you send to advertising channels. Data regeneration is the mechanism that ensures changes from the data source reach Mergado Editor and that edits in the editor are reflected in the output data flowing to the target platforms. Thanks to this mechanism, you gain control over what actually appears in your advertising.
