To help you get started, follow this build. 1) Create search only campaigns. I also recommend turning off partner network for now. 2) Build campaigns by categorizing keywords according to their position in the marketing funnel(you can have multiple campaigns). Create keywords in exact match only. Increase bidding for lower-funnel keywords 3) Sort keywords by ad group. Keep it tight. Add ad copy that is relevant to the ad group cluster. 3) Duplicate out the campaigns. Change match types of duplicate campaigns to broad. 4) Append + to keywords and replace space with + 5) Now you have both exact match and broad match modifier(BMM) campaigns. Use the BMM campaigns to capture new keywords.
