Why comparison shopping engines?

A comparison shopping engine is a platform with high conversion, which users target when they intend to buy. Their conversion is therefore much higher than for example with standard PPC advertising. Moreover, with Mergado you can manage your advertising on comparison shopping engines without interventions in the store’s administration.
Advertising on comparison engines is convenient for most online stores and products. Only when selling unique products consider carefully if such advertising can pay off.

Make sure you fill out all the fields correctly. All the required information are important for Mergado to work properly and for you to receive invoices with correct billing details and in a correct mailbox.
Then choose the desired billing period (step 3). You can change this anytime in the future depending on your or your client’s needs.

Before submitting please don’t forget to read and agree to our Terms of use (step 4).

After submitting you will receive a confirmation email to complete your registration.

When you log in you can create your first export and start managing your product campaigns.

It is important to say that creating an account is free and can be canceled anytime. You pay only after creating one or more exports. This is also when the 30-day free trial starts. The actual tariff depends on the total number of items in all your exports combined (see pricing for more information).

To be able to start optimizing your advertising first you need to create an export. Log in to your account and click Create export on the top right (image 3).

On the next page provide a URL address of your source XML feed (image 4). Mergado will regularly (every 4-8 hours) access this file to check for any updates in the feed (new products, price changes etc.). Click Continue and wait until Mergado processes the file (time depends on the number of items in the feed, usually few seconds).

When finished click Continue again to get to additional settings (image 5). You can choose which export format you want to create (choose from the list on the right - output format). To finish click Continue.

Now you have created an export and you get to an export overview page. Here all your exports for different channels are listed. Note that from one source XML file you can create an unlimited number of output exports. Just repeat the above procedure.

You can now proceed to edit the export feed by clicking the export name. Once you have finished editing and optimizing your product data, you want to copy and paste the URL address of the optimized output feed into a respective channel (e.g. facebook, google shopping, glami etc.). To find the URL address of the output XML, go to the Summary page of export and scroll down to the bottom of the Summary page. There you can find both the source XML feed address as well as the output feed address (image 6). You can copy the link of the output feed and paste where needed.

XML Audit is a tool that loads a data XML file with product information from your online store and on this file runs a series of test. A link to audit results is then sent to your email so you can have a nice overview of the major errors of your product feed. You can use this report to optimize your product campaign on comparison shopping services.

Plus, it’s totally free. You can run the audit as many times as you want!

To run an audit, go to Main Menu on Mergado Homepage and click XML Audit (Image 6). Alternatively, you can go directly to

Mergado Homepage XML Audit Menu

This leads you to a new audit page (image 7), where you can provide a URL address of your XML file (step 1) and an email address, where a link to your audit results will be sent (step 2). Finally, check that you agree to the terms and conditions and click Run audit (step 3).

Once the audit is finished, you will receive an email with the above-mentioned link. The report will present you all found errors sorted by their significance (image 8). First are the most serious issues colored in red. These errors would prevent your feed from being accepted by the respective comparison shopping service. Less serious warnings are colored in yellow. These would not cause your feed to be declined, but they would significantly impact your advertising. And colored in green are just recommendations to improve your feed to get even better results from your campaign.

Products page

On the Products page, you can see two columns (image 9). On the left (nu.1) are data coming into Mergado (from your input feed), on the right (nu.2) are data coming out of Mergado (in an output feed).

By clicking a product title you get to the product details which you can manually edit. You can edit any element of the product - name, description, price… Just choose an element that you want to edit, uncheck the “no change” box and type the desired value in the middle field and click Save changes (a rule is automatically created). However for changes to be applied, you need to go to the Rules page and on the top right click Apply rules.

Creating filters

On the products page, you are also able to filter products based on different conditions and create queries. This is really useful when you want to edit a large number of products at once. So first you create a query of e.g. products cheaper than 10 EUR, save this query and then use rules to edit these products (see below for more information about Rules).


(image 12) Choose an element (step 1) and a condition (step 2) based on which you want to filter your products. Mergado will try to offer you suggestions of possible values based on the actual values of the element that you chose in step 1. Below you can select if you search in input or output data (step 3).

This is a basic and most common way to work with a large number of products in bulk. For the more advanced users, the “contains regular expression” condition allows to define a more specific query (image 13).

Advanced interface

Those of you that master regular expressions can switch to advanced interface to make a query (image 14). Here you can combine several conditions and elements together to really define a precise query.
Example: You want to filter products that cost more than 20 EUR, is listed in a category containing “sandals” and is made by Nike. This would be the regular expression:

Remember to always save your query to be able to edit the filtered products (e.g. hide them, overwrite the text in the elements, define availability etc.).
