How Long Should a Title Tag Be?
Title tags are technically measured in pixels. It’s recommended that title tags must be of fifty to about seventy characters long. The character limits are based on how the titles display on desktop and mobile devices. Title tags that are longer than what Google displays in the search engine results pages (SERPs) will be shown cut off, which means that nobody will be able to read the full title tag in the SERPs if it’s longer than approximately 70 characters. Google claims that nobody at Google has ever said that the 40 to 70 character limits are what Google’s ranking algorithms are limited to indexing for ranking purposes.
So it does not make sense to accept the advice for limiting the title tag to 70 characters for ranking purposes when that recommendation is based on what is displayed. The typical title tag length recommendation is 50 to 60 characters, and Moz correctly notes that there is no actual limit to how many characters can be used. Understanding tokenization will help understand Does Not Recommend Title Tag Length because It’s a way to edit a document into chunks that make it easier to understand what sentences and words mean. Some chunks are sentences, and some chunks are single words. Given a character sequence and a defined document unit, tokenization is the task of chopping it up into pieces, called tokens, perhaps at the same time throwing away certain characters, such as punctuation.
