ClickFunnels has more SEO options than one might expect from a landing page builder. Since I am using this for paid advertising campaigns, I did not expect much in the way of SEO features. I was surprised to find that I could at least edit SEO metadata. But, it is still limiting compared to what I could achieve on WordPress. The Yoast SEO plug-in provides a more comprehensive toolset, and with some SEO know-how, you can achieve a lot of best practices using Yoast.
A good landing page should naturally lead a user to the conclusion that converting is in their best interest. To do that, however, you need to know exactly what you want them to do and why they might not want to do it. Then, throughout your landing page, you address their concerns and sell them on the value of what they get in exchange for converting.
Now your marketing automation funnel is giving you a boost at every stage: It responded within five minutes of their first contact, and that helped get you the chance to make your pitch. Now, after the pitch, you're ready to stay in contact and respond to objections in a friendly, targeted way. (And if they love the pitch, automation can help you stay in close touch until closing.)
