Marktplaats Pro has different minimum CPC values for their categories. For example, the minimum CPC value for E-readers could be €0.02 and the minimum CPC for cars could be €0.04. When the CPC value for an ad is set below the minimum CPC, you will get the following error in Channable:
If you click on the error, you will get an overview of the ads for which the CPC value does not reach Marktplaats Pro's minimum CPC value. In this overview you can also see the category ID number, the CPC value that's currently set and the minimum CPC value for products in this category.
To solve these errors you can follow the steps below.
Step 1 - Write down the categories & minimum CPC
From the overview write down the category ID numbers (category column) and the minimum CPC value (error column). The minimum CPC of the examples shown above are €0.03. The part "range([3,250])" means that the minimum CPC is €0.03 ("range ([4,250])" indicates a minimum CPC of €0.04, and so on)
Step 2 - Create a new field for CPC
If you don't have a field in which you can set your CPC values yet, you will have to add one now. To do so, you can follow the steps in this Help Center article. Add a field called "cpc" or something similar. You have now created an empty field for every product to set the CPC value for every Marktplaats Pro add. If you already have a field for this you can simply use that field in the next steps.
To set the CPC for your products follow the next steps:
- Go to APIs-> Marktplaats Pro -> Rules
- Click "Create new" and choose a name (e.g. "set cpc")
- Create a rule like the example below, using the category numbers that you have written down
Step 3 - Add CPC in Build & Run marketplace
You have now changed the CPC value for these items. The next step is to add the CPC field used above to the Build step of the marketplace. To do so, go to Build > Price Information, click on the plus and choose the cpc field.
The last thing you need to do is to send these changes to Marktplaats Pro. To do so, go to "APIs -> Marktpaats Pro" and click "Run now" The errors should now disappear in the Preview step of your Marktplaats Pro API. You have probably missed some categories if you still see CPC errors after this, repeat the steps above for those categories to fix these last errors!
