Your campaign will be successful if it attracts the right audience from the right source. Here are some things to consider befre driving traffic to your landing pages:

Create and maintain a consistent scent. Your ad copy, post, or tweet should match your landing page.
Know your audience. Find out where your audience likes to hang out online. What keywords they use to search when they want to solve a problem. Which social media channel they use. What's their age range. Try to create an ideal profile of your customer.
Test everything. Make sure your landing page works correctly. Try all the links, payment integrations, analytics, and message delivery.
