The length of landing pages
What’s more effective: long or short landing pages?
Here is an interesting analysis on the pros and cons of long and short landing pages. Some people have a perception that homepages must always fit in “above the fold”, but this is usually not the case.
Longer landing pages are better for generating more trust and credibility to motivate a Web visitor to convert since they have more room for information about your company and more opportunity to convince a visitor to perform an action.
The bigger the ask, the longer the page should be says KISSmetrics and Crazy Egg cofunder Neil Patel, which is a good rule of thumb to follow.
The advantage of this is that the user who scrolls through to the bottom where the sign-up form is located and views all the aspects of the page is typically a higher quality lead. Not to mention, the more quality text and properly optimized visuals on your landing pages the better they’ll do in the search engines in the long-term.
