Will the same phone affect search promotion?

Question

Search Engine Optimization

There are two sites. They are different, but they sell the same product. They also have the same contact numbers. Will the phone number somehow affect search engine promotion?
Does it make sense to make a new phone for one site?

Answer 1

Yes, it can have an effect.

Answer 2

Sites can be recognized as affiliates, then only one of them will be ranked by queries.
