What can I put on a 404 page?

[JoeyGedgaud]

When it comes to SEO what can I put on a 404 page? I want to add content that actually makes the page useful so visitors will more likely stay on the website. Most pages just have a big image of 404 and a couple sentences saying what happened. I am wondering if Google would like if there was blog suggestions or navigational functions?

However, once you have a good 404 page, it is really worthwhile to use the Moz tools to find and correct any 404 errors you have. Every redirected URL has the chance to enhance your domain authority.

Nope. You're in no way required or expected to tell someone why they've hit a 404. As long as you have a page with content, you're doing OK. Any effort beyond that will only benefit you.

Could there be any negative impact from Google? Are they looking for that 404 error information?

Your 404 page is a great way to serve visitors links to the pages that would be most relevant in general to them. It's also a great opportunity to show your brand and personality - and yes, as you mention - blog articles are a great next step for these pages. However, make sure that it makes sense for them to be there. If a visitor is within your blog domain / subdomain, then go for it. If they're not, consider a combination of things.

And yes, you can have more than one 404 page. Whether having multiple versions makes sense is up to you.
