Comparison Engines: How to avoid the most common mistakes when setting up campaigns

Advertising on comparison engines is pivotal for online stores, both rookies and those looking for new customers. When setting up advertising, you have to avoid frequently recurring errors. We have prepared several tips tailored for Google Shopping, GLAMI, or Heureka.

Get items higher in Google search

Have you targeted your advertising to the Google platform? One of its criteria is the correct identification of products. In the Google Merchant feed, you can use the BRAND, GTIN, and MPN identifiers for this purpose. Google requires using at least two of these three identifiers for each product. If your products have only one or no identifier, you must add the g:identifier_exists element to each product and fill it with a false value.

In Mergado, you may use the handy Rewrite rule for this type of feed editing, which you will apply to the selected query. For a simple step-by-step guide, see article 7 common Google Shopping feed flaws and how to fix them in Mergado.

How Pavel Novák, Besteto PPC specialist, perceives the Google Shopping channel

"I would recommend advertising on Google to every online store, especially now in the upcoming Christmas season. Google is the most used search engine in Europe. The Google Ads advertising system allows precise targeting of the right users, whether remarketing or targeting by interest. I would recommend the Google Shopping campaigns. They work well and bring a lot of new orders."

Improve advertising on GLAMI

Do you sell fashion products? Use the potential of the GLAMI engine to reach customers who buy clothes, shoes, and accessories. You will be ahead of the competition by running your ads efficiently. The most common problems are actions that you can manage in Mergado with a few clicks - for example, removing the size from the name and hiding products that are not in stock.

Remove size from the product name

When advertising on GLAMI, pay attention to the product name. According to their requirements, it cannot contain the size of the goods. You must specify this information only in the parameters. If you have such products in your feed, we recommend using Mergado.

The solution is simple - you create a Find and replace rule to remove sizes and other parametric data from PRODUCTNAME. Find the desired expression in the element and replace it with an empty field (do not write anything in the Replace field).

Among other things, GLAMI has several rules for product images (without additional texts, logos, etc.). You can get your image ad to a flawless state with the Feed Image Editor app, in which you can bulk edit everything you need.

Tips for GLAMI by Marek Daňko, a specialist from Feed Image Editor

"GLAMI is the ideal comparison engine for a range of fashion and accessories. It accents high-quality images, so be careful to meet all conditions. Due to image errors, 18 % of products on average do not get to GLAMI. The problem is watermarks, insufficient minimum dimensions, unsupported backgrounds, and missing images. However, you can check their quality in the free Image Validator."

Pair products on Heureka like a pro

The key to efficient advertising, not only on Heureka, is the flawless pairing of products. To classify the goods into the appropriate categories, you have to assign the online store to the created product card.

It often happens that the product name or category is not in the required form. You edit it with the CATEGORYTEXT and PRODUCTNAME elements. Using the Rename categories in bulk rule, you can correct them according to Heureka requirements. Mergado streamlines setting the categories via the implemented insinuator.

What Mergado consultant Luděk Volejník recommends for advertising on Heureka

Most Czech and Slovak online stores use advertising on Heureka, and I would recommend it to all new brands. Perhaps only to those who sell a unique assortment, it may not bring desired results. I describe it as the first step to start advertising on comparison engines. In Mergado, we have several functions and additional apps that can be used to manage Heureka advertising. That technically means it is possible to fine-tune a perfect feed for Heureka in Mergado.

Learn how to pair products with apps from the Mergado Store. They will improve the quality of advertising on Heureka and make your assortment more visible.

For a flawless start on each comparison engine, you need a data file in the required format. Not sure if it meets the requirements of the chosen platform? Check its status with the free Feed audit. You will get a technical analysis and recommendations on how to fix it with Mergado.
