To begin - I do not like the idea of headshots / banners - can be viewed as "age discriminatory". However, LI claims the those with headshots get 14x more views than those that do not. Also, those that do not include headshots are often thought of as scammers using a fake profile and / or hiding something else.
These are the reality and we must all deal with the way LI does business - like it or not. (Don't shoot to messenger - just providing perspective and data about the LI algorithm.)
With all that stated, please refresh your LinkedIn profile with a new headshot and banner. If you don’t have either, add them. Job searching in 2026 is all about being visible and, more importantly, trustworthy. Therefore, go with as conservative a headshot and banner as possible.
