I do SEO in an agency and have many clients. I always get the question, "Will that hurt my SEO?". When it comes to Meta Title and even Meta Description Length, I understand Google will truncate it which may result in a lower CTR, but does it actually hurt your ranking? I see in many cases Google will find keywords within a long meta description and display those and then in other cases it will simply truncate it. Is Google doing whatever they want willy-nilly or is there data behind this?
Thank you!
