How many keywords should I actually employ when utilizing AdWords to optimize the visibility of my advertisements? Is there an optimal number that balances efficacy with budgetary constraints? Considering the diverse array of products and services one might promote, wouldn’t the selection of keywords dictate not just the ad reach but also its overall performance? Moreover, should the emphasis lie solely on high-volume keywords, or is there merit in including long-tail variations that might yield a more targeted audience? As I delve deeper into the intricacies of keyword strategy, could it be possible that employing too many could dilute the focus of my campaign, leading to a less effective return on investment? Conversely, would restricting myself to a minimal set hinder my campaign’s potential reach? Therefore, what is the ideal approach to discerning the right quantity of keywords to harness for optimal results in AdWords?
