While acquiring leads is one of the top goals behind every marketing campaign, it is important to remember that not every lead converts.

  • Identify lead source and quality.
  • Monitor campaign performance and track real-time data of all of your leads. Use it to qualify leads and nurture them on every step of the buyer journey.
  • Prioritize your top leads and high-value accounts. Run personalized, highly targeted campaigns to engage them on and off your website to turn them into customers.



To get a grip on all of these strategies, you would need to use a lead generation tool or a group of tools.


Using marketing automation can not only help you generate more leads, but also increase your chances of driving conversions, as 80% of marketers agree. Many of them generated as much as 451% more leads with automation.
