meta.title-lengthThe title is too long or too short
Why it matters
Google sets no limit on a title's length, but it cuts the title link "as needed, typically to fit the device width", which in practice is around 60 characters on a desktop result. Whatever comes after that, often your brand name or the town you work in, is replaced by "…". A very short title ("Home") wastes the most-read line you have and tells nobody what the page offers.
Source: Influencing your title links in search results, which asks for titles that are "descriptive and concise". The 30 and 60 character marks are a widely used rule of thumb, not Google's numbers: the real cut is by pixel width.
How to fix it
Aim for 30 to 60 characters, with what the page is about first and the brand last, so that a cut loses the least important part:
