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

Too many on page links
Hi I know previously it was recommended to stick to under 100 links on the page, but I've run a crawl and mine are over this now with 130+ How important is this now? I've read a few articles to say it's not as crucial as before. Thanks!

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.

Effect of Removing Footer Links In all Pages Except Home Page
Dear MOZ Community: In an effort to improve the user interface of our business website (a New York CIty commercial real estate agency) my designer eliminated a standardized footer containing links to about 20 pages. The new design maintains this footer on the home page, but all other pages (about 600 eliminate the footer). The new design does a very good job eliminating non essential items. Most of the changes remove or reduce the size of unnecessary design elements. The footer removal is the only change really effect the link structure. The new design is not launched yet. Hoping to receive some good advice from the MOZ community before proceeding My concern is that removing these links could have an adverse or unpredictable effect on ranking. Last Summer we launched a completely redesigned version of the site and our ranking collapsed for 3 months. However unlike the previous upgrade this modifications does not URL names, tags, text or any major element. Only major change is the footer removal. Some of the footer pages provide good (not critical) info for visitors. Note the footer will still appear on the home page but will be removed on the interior pages. Are we risking any detrimental ranking effect by removing this footer? Can we compensate by adding text links to these pages if the links from the footer are removed? Seems irregular to have a home page footer but no footer on the other pages. Are we inviting any downgrade, penalty, adverse SEO effect by implementing this? I very much like the new design but do not want to risk a fall in rank and traffic. Thanks for your input!!!

Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

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!
