But I disagree.
Let's say your landing page has a conversion rate of 40%. So 60% of your clicks aren't even gonna see the sales page? Even if you were able to get your landing page conversion rate up really high (like 70-80%), you're still leaving 20-30% of customers on the table.
Yeah, yeah, you could argue that you'll make up for it later when you email them with promotions, but what I've experienced with PPC advertising is that the emails typically don't get opened much because the people visiting your landing page are just interested in what you're offering. But if you send them directly to the sales page, they'll probably be more interested in what the sales page is offering.
That's my theory anyway. I've tried both methods and I'm actually having more success with sending the traffic directly to the sales page. What's your opinion?
