Title is likely to be truncated in search results

What this means

Google cuts result titles on rendered PIXEL width, not on character count, so the usual "under 60 characters" rule of thumb both over- and under-fires: a title full of "W"s and capitals is clipped well before 60 characters, while one full of "i"s and "l"s survives past 70. This check estimates the rendered width per character and flags titles projected past ~580px.

How to fix it

Front-load the words that must survive the cut — the primary phrase first, brand and qualifiers last — and shorten by replacing wide words rather than by counting characters.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
