Here is the Ultimate 2023 Landing page Checklist

The Offer

• A clear,"tightly-written" headline, and
sub-headline that answers'What is it?' and
'What does it do for me?'
• The offer is something the target
audience wants/needs.
• The offer articulation is personalized for
the specific target market.


Form/CTA

• The form is immediately visible.
• The number of form fields is appropriate
for the offer, e.g., high commitment offers
have longer forms & lower commitment
offers have shorter form fields.

Trust
• Layout is smooth and revolves around a
single idea.
• Fonts are consistent
•Images are authentic
• The page flow is intuitive to the user.
Your testimonials are not anonymous.
• You testimonials include a name, photo,
job title, and place of business.


Design

• The page and design guide the eye to
high priority sections.

• The fonts, colors, imagery, and copy
compliment each other.
• The supporting imagery,e.g., features,
product use, etc. .. does not compete with
your CTA.
• The supporting imagery, e.g., features,
product use, etc. .. does not break the page
theme.
• Headline needs to be "tightened" or only
answers one of the key questions.
• Headline isn't as compelling as it could
be or is somewhat hypey or misleading.
• The copy and promises of the ad (or
referring source) are somewhat articulated
on the page.
• The design of the landing page is
somewhat consistent with the ad (or
referring source).
