does 404 page is indexed by google?

according to my research its not.
other opinions?

 

If it returns a 404 header it won't be indexed. Otherwise it will.

 

If it returns a 404 header response it won't be indexed. If it doesn't have that, then it will be indexed.

Hope i helped,

Google cannot index such a page, because it's "not found".

 

Almost verbatim the post above you by mad.

 

Agree with that.

 

if a page is giving 404 error (not found error), there is no reason google to index that page

 

I would suggest adding a custom 404 page so that Google will take that page in.

perhaps redirecting any 404's to a site map or any other page with some value.

 

my 404 page is indexed...I think that's because I created a custom one /404.html I can't remember if I put a link to it somewhere on the site

 

Why google indexed the page that cannot be found?

 

I do not think Google will indexed this page,it have no value anyway.Google own indexed those it think is valueable.
