Basically the takeaway here is to not make the user think any more than they have to which distracts them from their overarching task.
Preventing cognitive overload is actually quite simple. Keep your design simple.
Remove redundancies – combine pages or menu items
Get rid of everything that’s not essential
Minimize the number of steps users must take or the amount of effort they must expend
If you have too much content, you must learn how to organize it.
Chunking – breaking text and multimedia content into smaller chunks to help users process, understand, and remember it better.
Keep a consistent format throughout the website.
Stick to ONE ACTION COLOR on your website design and digital branding - and these are your best options by far.
