      I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl.

      Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

          Hi Brad

          Sorry I have only just come back to you - it was late night here in the UK, but it looks like Alan has already answered your question 🙂

          Have you tested your 404 page with fetch as Google in webmaster tools - you should see that it can see the links on your 404 page and as such will continue crawling them as Alan has said.

          So what is a benefit to a user will also be a benefit to Google crawling your site in my opinion 🙂

            Sorry, yes, it should crawl the links - they used to do that.

            But you can prove it to yourself, by doing what I said - and then report back.

              Yes it will continue crawling or yes it will stop the crawl?

                Yes and you can test it by creating a page that is linked from nowhere else and then check your logs or analytics

                  Hey Matt,

                  Thanks for the reply. I'm aware of all the best practice stuff but thanks for sending through. It didn't quite answer my question so let me rephrase...

                  Will a bot follow a hyperlink (like the example below) on a 404 page or will it stop the crawl on that page (not on the whole site) because the header response code is a 404?

                  Recent Post Title

                    Hi Brad

                    Firstly it is great from a usability point of view to have a custom 404 page and I would link it to your most popular content and maybe add a search feature on the page for your site to help find the content that is missing. I have come across some nice 404s that actually have very concise sitemap in order to help the visitor navigate the site.In order to prevent Google from indexing your 404 page you need to make sure it returns an actuall 404 HTTP status code.

                    In order to understand how Goolgebot crawls your site I would look at the following post from Google themselves - https://support.google.com/webmasters/answer/182072?hl=en

                    Rather than being concerned about a 404 page having links on to keep the crawl going make sure you have an XML sitemap that you have submitted to Google via Webmaster Tools as this will help your crawl process.

                    Googlebot alots a set amount of time to crawling your site and it doesn't just stop crawling because it encounters a 404 error. However make sure that you monitor Google Webmaster Tools and take care of any reported 404s with 301 redirects for instance if the page has changed location. You will notice that Googlebot reports 404 erros on the days it finds them and these can often be multiple 404 errors encountered in one visit to your site by Googlebot. Keeing an eye on this and making sure you keep it updated will make your site as crawl efficient as possible which is clearly what you are after - as we all are 😄

                    I thought this would also be interesting reading in relation to this - http://googlewebmastercentral.blogspot.co.uk/2011/05/do-404s-hurt-my-site.html

                    Hope this helps

                      Top hierarchy pages vs footer links vs header links

                      Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

                      Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?

                      We are building URLs dynamically with apache rewrite.
                      When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).

                      Links from non-indexed pages

                      Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed. These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

                      Whats the best way to remove search indexed pages on magento?

                      A new client ( aqmp.com.br/ )call me yestarday and she told me since they moved on magento they droped down more than US$ 20.000 in sales revenue ( monthly)... I´ve just checked the webmaster tool and I´ve just discovered the number of crawled pages went from 3.260 to 75.000 since magento started... magento is creating lots of pages with queries like search and filters. Example: http://aqmp.com.br/acessorios/lencos.html http://aqmp.com.br/acessorios/lencos.html?mode=grid http://aqmp.com.br/acessorios/lencos.html?dir=desc&order=name Add a instruction on robots.txt is the best way to remove unnecessary pages of the search engine?

                      Outbound link to PDF vs outbound link to page

                      If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

                      Do 404 pages pass link juice? And best practices...

                      Last year Google said bad links to 404 pages wouldn't hurt your site. Could that still be the case in light of recent Google updates to try and combat spammy links and negative SEO? Can links to 404 pages benefit a website and pass link juice? I'd assume at the very least that any link juice will pass through links FROM the 404 page? Many websites have great 404 pages that get linked to: http://www.opensiteexplorer.org/links?site=http%3A%2F%2Fretardzone.com%2F404 - that was the first of four I checked from the "60 Really Cool...404 Pages" that actually returned the 404 HTTP Status! So apologies if you find the word 'retard' offensive. According to Open Site Explorer it has a decent Page Authority and number of backlinks - but it doesn't show in Google's SERPs. I'd never do it, but if you have a particularly well-linked to 404 page, is there an argument for giving it 200 OK Status? Finally, what are the best practices regarding 404s and address bar links? For example, if
                      www.examplesite.com/3rwdfs returns a 404 error, should I make that redirect to
                      www.examplesite.com/404 or leave it as is? Redirecting to www.examplesite.com/404 might not be user-friendly as people won't be able to correct the URL in the address bar. But if I have a great  404 page that people link to, I don't want links going to loads of random pages do I? Is either way considered best practice? If I did a 301 redirect I guess it would send the wrong signal to the crawlers? Should I use a 302 redirect, or even a 304 Not Modified redirect?

                      Do search engines understand special/foreign characters?

                      We carry a few brands that have special foreign characters, e.g., Kühl, Lolë, but do search engines recognize special unicode characters? Obviously we would want to spend more energy optimizing keywords that potential customers can type with a keyboard, but is it worthwhile to throw in some encoded keywords and anchor text for people that copy-paste these words into a search? Do search engines typically equate special characters to their closest English equivalent, or are "Kuhl", "Kühl" and "Kühl" three entirely different terms?
