Hi, I am looking to add our brand name to the ends of our meta titles to improve SEO. so it will be in this typical format:

'product title & details | Brand'

Currently we are keeping our titles under 60 characters, but I'm reading conflicting stuff that this only ensures google displays it correctly. Does having titles longer that 60 negatively affect ranking?

I don't want to have to cut out important keywords to be able to fit in the '|brand'
