Too many companies send their advertising, email, or social media traffic to their homepage. This is a huge missed opportunity. When you know a stream of targeted traffic will be coming to your website, you can increase the likelihood of converting that traffic into leads by using a targeted landing page.
For example, imagine you have a Google AdWords PPC ad running for one of your best keywords. Even if you advertise how great your company is (a boring offer for any company) and someone (amazingly) clicks through on that ad, do you want to send them to your homepage? When they land on your homepage, what are they supposed to do? What do you want them to do? Once you figure out what you want the visitor to do, make it easier for them to do just that. Send them to a landing page that prompts them to complete that action. You’ll see the effectiveness of your online marketing improve dramatically.
