Is it worth doing a multi-brand online store?

Question

Search Engine Optimization

Firework! The company has 3 websites of an online store selling equipment. Each online store sells a specific brand. Everyone has one niche, but there is a certain categorization. Each online store complements each other.

Question: what is the best way to proceed?

Make one store of 3 brands, thereby trying to take positions not by brand names, but by category keys, such as: buy a refrigerator. And those 3 stores are easy to maintain.

Answer 1

Depends on user behavior. If it is possible to make up-sells, offer relative products, then it is better to combine everything in one store and promote by category keywords, allowing the client to choose among brands.
If, however, the user is not ready to buy additional goods, but comes only for a highly specialized product, then it is better to promote brands separately.

Answer 2

It is logical to ask your SEO specialist and what prevents him from getting into positions now according to these words?

Answer 3

Make one store of 3 brands, thereby trying to take positions not by brand names, but by category keys, such as: buy a refrigerator. And those 3 stores are easy to maintain.

It seems to me that it will be D&G (expensive and stupid).

Answer 4

Here it is necessary to evaluate how quickly the new IM will be able to reach the same indicators, what will be the costs and at least predict how much more efficient such IM will be.
But in general, the trend for marketplaces has been outlined for a long time, and you are unlikely to lose much if you make the 4th project.
It will be cool if the 4th project will carry not only the combined assortment, but also additional chips so that the user can increase the value of such a store compared to existing ones.
