If you have struggled trying to create a decent squeeze page for WordPress, you are not alone! I tried for several months to develop my own with disastrous results.
At first I tried to create my own in html
Without a template, you have very little hope. With a template it is not terribly difficult, but it is still a pain to update each page (outside of WordPress) — particularly if you are not a fluent coder. Also, I am already using WordPress and would prefer to create a squeeze page from within it.
