Factors that Make a Perfume a Best Perfume
Here are some factors that make a perfume the best.

Branding
Branding is probably the most important factor that contributes a lot in making a perfume the best. There are two types of brands i.e. traditional branding and newer branding or celebrity endorsed perfumes. These days, people have become more conscious about branding. Therefore, brand identity of a perfume should be well reputed, strong and established to make it a good perfume.

Cost
Cost is another major factor that can make a perfume best. Most of the people have a misconception that a costly perfume is of good quality but the fact is that less costly perfumes are more liked by the people. Because it is not always necessary that cheap things are of lower quantity. A reasonable price is a factor that let a perfume stand in the list of best perfumes.

Fragrance
When trying to make a best perfume, a manufacturer must also consider scent, as it is an obvious factor. Fragrance is the main factor that urges a person to buy a particular perfume. It is impossible to make a perfume that is liked by everyone because another may not like a smell that is liked by one person but manufactures know about a number of scents that can appeal to different demographics. Manufactures should try to make such perfumes that can be liked by most of the people.

Long-Lasting Scent
Perfume manufacturers should also consider the permanence of a perfume. People like those perfumes whose scent lasts for longer period of time. Therefore longevity of a perfume scent becomes a factor that can make a perfume a best perfume.
There is not a single factor that contributes to the success of a perfume. Manufacturers consider a lot of other aspects as well but those mentioned above are the most important according to my opinion.
