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

404 Errors flaring on nonexistent or unpublished pages – should we be concerned for SEO?
Hello! We keep getting "critical crawler" notifications on Moz because of firing 404 codes. We've checked each page and know that we are not linking to them anywhere on our site, they are not published and they are not indexed on Google. It's only happened since we migrated our blog to Hubspot so we think it has something to do with the test pages their developers had set up and that they are just lingering in our code somewhere. However, we are still concerned having these codes fire implies negative consequences for our SEO. Is this the case? Should we be concerned about these 404 codes despite the pages from those URLs not actually existing? Thank you!

Crawled page count in Search console
Hi Guys, I'm working on a project (premium-hookahs.nl) where I stumble upon a situation I can’t address. Attached is a screenshot of the crawled pages in Search Console. History: Doing to technical difficulties this webshop didn’t always no index filterpages resulting in thousands of duplicated pages. In reality this webshops has less than 1000 individual pages. At this point we took the following steps to result this: Noindex filterpages. Exclude those filterspages in Search Console and robots.txt. Canonical the filterpages to the relevant categoriepages. This however didn’t result in Google crawling less pages. Although the implementation wasn’t always sound (technical problems during updates) I’m sure this setup has been the same for the last two weeks. Personally I expected a drop of crawled pages but they are still sky high. Can’t imagine Google visits this site 40 times a day. To complicate the situation: We’re running an experiment to gain positions on around 250 long term searches. A few filters will be indexed (size, color, number of hoses and flavors) and three of them can be combined. This results in around 250 extra pages. Meta titles, descriptions, h1 and texts are unique as well. Questions: - Excluding in robots.txt should result in Google not crawling those pages right? - Is this number of crawled pages normal for a website with around 1000 unique pages? - What am I missing?

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.

Do I have to many internal links which is diluting link juice to less important pages
Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

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 -
How Do You Remove Video Thumbnails From Google Search Result Pages?
This is going to be a long question, but, in a nutshell, I am asking if anyone knows how to remove video thumbnails from Google's search result pages? We have had video thumbnails show up next to many of our organic listings in Google's search result pages for several months. To be clear, these are organic listings for our site, not results from performing a video search. When you click on the thumbnail or our listing title, you go to the same page on our site - a list of products or the product page. Although it was initially believed that these thumbnails drew the eye to our listings and that we would receive more traffic, we are actually seeing severe year over year declines in traffic to our category pages with thumbnails vs. category pages without thumbnails (where average rank remained relatively constant). We believe this decline is due to several things: An old date stamp that makes our listing look outdated (despite the fact that we can prove Google has spidered and updated their cache of these pages as recent as 2 days ago). We have no idea where Google is getting this datestamp from. An unrelated thumbnail to the page title, etc. - sometimes a picture of a man's face when the category is for women's handbags A difference in intent - user intends to shop or browse, not watch a video. They skip our listing because it looks like a video even though both the thumbnail and our listing click through to a category page of products. So we want to remove these video thumbnails from Google's search results without removing our pages from the index. Does anyone know how to do this? We believed that this connection between category page and video was happening in our video sitemap. We have removed all reference to video and category pages in the sitemap. After making this change and resubmitting the sitemap in Webmaster Tools, we have not seen any changes in the search results (it's been over 2 weeks). I've been reading and it appears many believe that Google can identify video embedded in pages. That makes sense. We can certainly remove videos from our category pages to truly remove the connection between category page URL and video thumbnail. However, I don't believe this is enough because in some cases you can find video thumbnails next to listings where the page has not had a video thumbnail in months (example: search for "leather handbags" and find www.ebags.com/category/handbags/m/leather - that video does not exist on that page and has not for months. Similarly, do a search for "handbags" and find www.ebags.com/department/handbags. That video has not been on that page since 2010. Any ideas?

Best practice for removing indexed internal search pages from Google?
Hi Mozzers I know that it’s best practice to block Google from indexing internal search pages, but what’s best practice when “the damage is done”? I have a project where a substantial part of our visitors and income lands on an internal search page, because Google has indexed them (about 3 %). I would like to block Google from indexing the search pages via the meta noindex,follow tag because: Google Guidelines: “Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.” http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769 Bad user experience The search pages are (probably) stealing rankings from our real landing pages Webmaster Notification: “Googlebot found an extremely high number of URLs on your site” with links to our internal search results I want to use the meta tag to keep the link juice flowing. Do you recommend using the robots.txt instead? If yes, why? Should we just go dark on the internal search pages, or how shall we proceed with blocking them? I’m looking forward to your answer! Edit: Google have currently indexed several million of our internal search pages.

Generating 404 Errors but the Pages Exist
Hey I have recently come across an issue with several of a sites urls being seen as a 404 by bots such as Xenu, SEOMoz, Google Web Tools etc. The funny thing is, the pages exist and display fine. This happens on many of the pages which use the Modx CMS, but the index is fine. The wordpress blog in /blog/ all works fine. The only thing I can think of is that I have a conflict in the htaccess, but troubleshooting this is difficult, any tool I have found online seem useless. Have tried to rollback to previous versions but still does not work. Anyone had any experience of similar issues? Many thanks K.
