How long should someone spend on your website?
Build your website with this in mind:
You want visitors to stay long enough to get their needs met, for example getting information about your industry, your offerings, or your pricing.
But you don't want your website to be so long and confusing that people leave overwhelmed and frustrated.
Even if you have tons of helpful information on your website, you don't want to distract from the main purpose of your website: whether that's to sell something, answer questions, or give your contact info.
Unless you run a social media platform where you're selling ads, you want your user to spend just the right amount of time on your site. No more or less.
