Do search engines crawl links on 404 pages?
-
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?

Okay, thanks Alan!

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?

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

Internal links to landing pages
Hi, we are in the process of building a new website and we have 12 different locations and for theses 12 locations we have landing pages with unique copy on the following: 1. Marketing...2 SEO....3. PPC....4. Web Design Therefor there are 48 landing pages. The marketing pages are the most important ones to us in terms of traffic and priority. My question is: 1. Should we put a dropdown of the are pages in the main header under locations that link to the area marketing pages? 2. What is the best way to link all the sub pages such as London Web Design? Should these links just be coming off the London marketing page? or should we have a sitemap in the footer that lists every page? Thanks

Should I noindex the site search page? It is generating 4% of my organic traffic.
I read about some recommendations to noindex the URL of the site search.
Intermediate & Advanced SEO | | lcourse
Checked in analytics that site search URL generated about 4% of my total organic search traffic (<2% of sales). My reasoning is that site search may generate duplicated content issues and may prevent the more relevant product or category pages from showing up instead. Would you noindex this page or not? Any thoughts?0 -
Links from new sites with no link juice
Hi Guys, Do backlinks from a bunch of new sites pass any value to our site? I've heard a lot from some "SEO experts" say that it is an effective link building strategy to build a bunch of new sites and link them to our main site. I highly doubt that... To me, a new site is a new site, which means it won't have any backlinks in the beginning (most likely), so a backlink from this site won't pass too much link juice. Right? In my humble opinion this is not a good strategy any more...if you build new sites for the sake of getting links. This is just wrong. But, if you do have some unique content and you want to share with others on that particular topic, then you can definitely create a blog and write content and start getting links. And over time, the domain authority will increase, then a backlink from this site will become more valuable? I am not a SEO expert myself, so I am eager to hear your thoughts. Thanks.

Best way to block a search engine from crawling a link?
If we have one page on our site that is is only linked to by one other page, what is the best way to block crawler access to that page? I know we could set the link to "nofollow" and that would prevent the crawler from passing any authority, and we can set the page to "noindex" to prevent it from appearing in search results, but what is the best way to prevent the crawler from accessing that one link?
