Wondering: should you use AdWords? If you’re paying big bucks for the most expensive Google AdWords keywords in an industry, be sure to implement pay-per-click marketing best practices. Here are some things to keep in mind:

  • Quality Score: A high AdWords Quality Score can lower your CPC and help you pay less for your most successful keywords. Find the right keyword niches and break up large keyword lists into smaller, more targeted lists that you can easily write targeted ad copy for, resulting in better Quality Scores and better keyword rankings.
  • Be specific: Target specific 35-word keywords. You can use a Google AdWords keyword tool to generate specific keyword ideas, both broad and long keywords.
  • Use negative keywords: Irrelevant keywords generate costly clicks that never convert. If you’re bidding on the most expensive keywords at $ 50 per click, negative keywords are essential.
    Focus on Relevance
  • Landing Page Optimization – While most AdWords conversion rates stay around 2%, we often find that landing pages convert by 20% or even 30%. The key to landing page optimization is constantly testing different types of offers and seeing how people react.
  • Expand on Display: Especially if you want to increase brand awareness, the Display Network is a great way to drive affordable clicks. And with tools like our Smart Ads Creator, you can set up displays faster and more efficiently than ever.
