Hi Austin, My team and I are concerned about broad match type keywords because they are draining our clients' budgets with a low conversion rate. We are considering some quality criteria to choose among the broad match keywords recommended by Google when campaigns are limited by search volume. The main criterion we’ve identified is the search volume of the keyword. Indeed, if keywords have high traffic, the chance of attracting junk traffic is higher. Thanks for letting us know if you have any other suggestions for criteria we could use.
