Google folded broad match modifier into phrase match in 2021, but plenty of keyword lists, templates and even tools still carry the plus signs. Paste one in and the tool strips them and gives you clean phrase and exact versions.
How we structure keywords
For a local service business we usually run exact and phrase match in one campaign for control, with broad match in a separate campaign on target CPA bidding once the account has 30 or more conversions a month. Negatives are shared across all of them through a negative keyword list, starting with the sector list above and growing from the search terms report every week.
