A marketing landing page isn't a blog post. Your reader gives you about 8 seconds before bouncing. Your readability targets should be aggressive.
Page-level targets
Section by section
Hero headline. Aim for 8 words, 14 syllables. "The free home affordability calculator" is better than "A comprehensive real-estate-affordability-estimation solution."
Subheadline. One sentence. 15 words max. Plain nouns and strong verbs.
Feature bullets. Parallel structure. Lead each bullet with a verb. "Compare 20 lenders," "Track monthly payment," "See 30-year total cost."
CTA. Two to four words. "Try it free" > "Start your free trial today."
FAQ. Questions in the voice of the reader. Answers in 2–3 sentences each. Our data shows FAQ with Flesch 75+ gets featured snippets 3x more than FAQ with Flesch 60.
Run the whole page through the grader. Paste just the visible-above-fold text first — that's what determines whether visitors stay.
