A product title tag is an HTML element that specifies the product title of the product. Product title tags are displayed on search engine results pages (SERPs) as the clickable headline for a given result and are important for usability, SEO, and social sharing. The product title tag of a product is meant to be an accurate and concise description of product content.
The recommendation for meta product title length is around 55 to 60 characters.
Why product meta-title is important?
Meta title tags in general are a major factor in helping search engines understand what your product is about, and they are the first impression many people have of your product. Title tags are used in three key places: (1) search engine results pages (SERPs), (2) web browsers, and (3) social networks. So it is very important to set a product meta title when creating a product listing.
