Completeness
Search engines are constantly improving and setting new product data requirements.
Comprehensive product data empowers you to reach more users by improving your rankings in search results.
Not only that, but when users are searching for a specific product on your website having all the important product information,
e.g. model number, upc, brand name, allows them to easily find exactly what they are looking for.
Let's say a user tries to find a product at your online store by searching for a brand name and model number combo.
You do have that product but not the complete information too, that is, you do not have its model number.
So it may happen that the user gets displayed all products that are from said brand.
What it also may happen is that the search doesn't retrieve any product at all.
At the same time, there are other online stores carrying the same product, but they do have rich product data, thus users
will be able to easily find the specific product.
Comprehensive product data is the most effective way of ensuring that your users find exactly what
they need at your online store. For you this means higher conversion rates and higher revenue.
