What is not an effective PPC strategy?

Avoiding users who are just clicking on ads is not an effective PPC strategy because PPC campaigns are designed to attract clicks. The goal is to get relevant users to click on your ads and then convert them on your landing page. While click fraud or accidental clicks can occur, a blanket strategy of "avoiding users who are just clicking" misunderstands the fundamental mechanism of PPC. Effective strategies focus on attracting qualified clicks, not avoiding clicks altogether. The other options describe essential components of a successful PPC campaign: compelling ads drive clicks, effective landing pages convert visitors, targeted plans reach the right audience, and defined milestones track user progress towards purchase.
