# Common mapping mistakes

Mapping in a product index can be complex. This is a common occurrence in technology: the more robust and performative a product is, oftentimes means there are more ways to make mistakes. Here are a few common mapping mistakes and how you can avoid them:

- [Map multiple values into one](/v1/docs/mapping-multiple-values-into-one)
- [Map models as brands or missing brands](/v1/docs/mapping-models-as-brands-or-missing-brands)
- [Handle invalid products](/v1/docs/handling-invalid-products)
- [Handle invalid URLs](/v1/docs/handling-invalid-urls)
