Checklist
Content
Make sure all content is double-checked. All textual content is clean and proof-read. All images are compressed and corresponding to text.
Responsiveness
Test how components look on different sizes. Try to stretch the breakpoint in preview mode, to see if any of the component breaks. When creating new components, some desktop versions might not work well on mobile, meaning: you will need to create a separate mobile version (example: navigation bar).
Navigation menu
Each landing page has sections: Features, Testimonials, How it works, Pricing. If you create every landing page in this file, then a separate navigation bar will need to be created - pointing to the right sections in each landing page. Otherwise, they will all point to one page (Activity LP for example).
Page settings
Make sure to check page settings before launching the landing page. You can define description and Social preview image for each page.
