I hate writing intros.
(me writing an intro)
Default 404 pages are ugly, and if you make your custom WordPress theme, it will not be styled at all.
It doesn't look pretty, right?
Working with a lot of WordPress themes, I found that sometimes I need something else on the 404...
I have a client with a website which has thousand dynamic pages. Every day I got more and more 404 pages. I don't want to apply redirects cuz it will be endless process. Definitely that 404 pages decrease the crawl budget and I came up with the idea to add noindex tag to 404 page...
