Product titles are used to provide all the required information about your products.
In order to help your users perceive the specifics of each product better and find exactly what they are looking for, descriptive product titles are a must.
A study in 2018 found that descriptive quality product titles increased conversion rates and vice-versa. Scientists were also able to find stores with product descriptions of higher quality based on conversion rates.
BONUS TIP: Keep the title under 65 characters so it is easy to read and fully appears in Google search results.
