One help tool for agencies / web developers to QC and proofread websites is https://www.triplechecker.com. It’s basically like the Grammarly for proofreading and spell checking an entire website.
Curious what other tools do you use to spell check websites?
Don’t you check your copy BEFORE going to the trouble of formatting it onto a website?
(What am I saying? No one checks their copy until the printer proof comes in, why should web be any different… 
)
It’s a fair point. Main difference is if a site is public, any errors you make are public as well.
If you have errors in your public site, yer not doin it right. 
Over the years, I’ve been hired several times to redesign, clean up, and improve the content on already-built websites. This checker would have come in handy for those projects. However, I would have only done this once per website, so the subscription payment model would have made no sense.
Appreciate the comment. Reasonable point. Depends somewhat on how often new content is added/edited, how many different users have access to making changes.
Yes, that’s true; not every website is ideally managed. However, when someone on the team is needed to constantly clean up for others’ inability to spell and construct well-structured information before adding it to the website, there’s a larger problem to address.
As @PrintDriver said, those people’s work should be copyedited before it’s added to the website—not afterward. Then again, dysfunctional work flows do exist, and I run across my share of them.
