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

My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages.
Hello, My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages. I have contacted my theme company but not sure what could have done this. Any ideas? The original posts/pages are still correct and working it just looks like it did duplicates and added void(0 to the end of each post/page. Questions: There is no way to undo this correct? Do I have to do a redirect on each of these? Will this hurt my rankings and domain authority? Any suggestions would be appreciated. Thanks, Wade

What's the best possible URL structure for a local search engine?
Hi Mozzers, I'm working at AskMe.com which is a local search engine in India i.e if you're standing somewhere & looking for the pizza joints nearby, we pick your current location and share the list of pizza outlets nearby along with ratings, reviews etc. about these outlets. Right now, our URL structure looks like www.askme.com/delhi/pizza-outlets for the city specific category pages (here, "Delhi" is the city name and "Pizza Outlets" is the category) and www.askme.com/delhi/pizza-outlets/in/saket for a category page in a particular area (here "Saket") in a city. The URL looks a little different if you're searching for something which is not a category (or not mapped to a category, in which case we 301 redirect you to the category page), it looks like www.askme.com/delhi/search/pizza-huts/in/saket if you're searching for pizza huts in Saket, Delhi as "pizza huts" is neither a category nor its mapped to any category. We're also dealing in ads & deals along with our very own e-commerce brand AskMeBazaar.com to make the better user experience and one stop shop for our customers. Now, we're working on URL restructure project and my question to you all SEO rockstars is, what can be the best possible URL structure we can have? Assume, we have kick-ass developers who can manage any given URL structure at backend.

How can I make sure Google is crawling a link from an iframe (video)?
Do they crawl backlinks from an iframe example from a Youtube video embedded in a blog post? TIA!

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.
Intermediate & Advanced SEO | | lcourse
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).0 -
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?

Is it better "nofollow" or "follow" links to external social pages?
Hello, I have four outbound links from my site home page taking users to join us on our social Network pages (Twitter, FB, YT and Google+). if you look at my site home page, you can find those 4 links as 4 large buttons on the right column of the page: http://www.virtualsheetmusic.com/ Here is my question: do you think it is better for me to add the rel="nofollow" directive to those 4 links or allow Google to follow? From a PR prospective, I am sure that would be better to apply the nofollow tag, but I would like Google to understand that we have a presence on those 4 social channels and to make clearly a correlation between our official website and our official social channels (and then to let Google understand that our social channels are legitimate and related to us), but I am afraid the nofollow directive could prevent that. What's the best move in this case? What do you suggest to do? Maybe the nofollow is irrelevant to allow Google to correlate our website to our legitimate social channels, but I am not sure about that. Any suggestions are very welcome. Thank you in advance!

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
