Using a hyphen in title tags and the impact of spaces

[lina_digital]

Hi

I am trying to arrive at a best practice template for a title tag for my organization so does the following template still holds

Primary Keyword - Secondary Keyword | Brand Name

will anything be impacted  if I eliminate the spaces between the hyphen, will search bots be still able to treat the first one as a priority and the second as the secondary?

Primary Keyword-Secondary Keyword | Brand Name

thank you

Providing you've got a separator (like a hyphen) it shouldn't make any difference. I will be more concerned about the grammar and how it looks to the searcher.
If it was me and I was using it to separate two different phrases I would make sure it had spaces either side. However, if it's a hyphenated word it wouldn't make sense to use spaces.
