I want to give best suggestion or idea according to SEO point. Now a days SEO is more important for all website. In Strikingly there is no 404 page means when a user search wrong it will redirect to home page. but its not a solution.
In another CMS Like Wordpress, Joomla etc.when a user search wrong information it will show 404 page and show move to home page
Kindly add this page asap. coz its important for you and customers
