HOW TO TEST BROAD MATCH KEYWORDS WITHOUT WASTING SPEND

Summary from the TLDR Marketing newsletter

To avoid wasting ad spend, start a new campaign with select top-performing keywords. Avoid switching all match types to broad match at once to prevent inefficiencies. Monitor performance long-term, as broad match keywords take time to optimize. Conduct daily search term checks to refine targeting and add negative keywords as needed. Use automated bidding strategies like Target CPA or ROAS, and include thematically similar keywords to enhance learning while avoiding Single Keyword Ad Groups.
