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

Crawl Stats Decline After Site Launch (Pages Crawled Per Day, KB Downloaded Per Day)
Hi all, I have been looking into this for about a month and haven't been able to figure out what is going on with this situation. We recently did a website re-design and moved from a separate mobile site to responsive. After the launch, I immediately noticed a decline in pages crawled per day and KB downloaded per day in the crawl stats. I expected the opposite to happen as I figured Google would be crawling more pages for a while to figure out the new site. There was also an increase in time spent downloading a page. This has went back down but the pages crawled has never went back up. Some notes about the re-design: URLs did not change Mobile URLs were redirected Images were moved from a subdomain (images.sitename.com) to Amazon S3 Had an immediate decline in both organic and paid traffic (roughly 20-30% for each channel) I have not been able to find any glaring issues in search console as indexation looks good, no spike in 404s, or mobile usability issues. Just wondering if anyone has an idea or insight into what caused the drop in pages crawled? Here is the robots.txt and attaching a photo of the crawl stats. User-agent: ShopWiki Disallow: / User-agent: deepcrawl Disallow: / User-agent: Speedy Disallow: / User-agent: SLI_Systems_Indexer Disallow: / User-agent: Yandex Disallow: / User-agent: MJ12bot Disallow: / User-agent: BrightEdge Crawler/1.0 (crawler@brightedge.com) Disallow: / User-agent: * Crawl-delay: 5 Disallow: /cart/ Disallow: /compare/ ```[fSAOL0](https://ibb.co/fSAOL0)

Google Adsbot crawling order confirmation pages?
Hi, We have had roughly 1000+ requests per 24 hours from Google-adsbot to our confirmation pages. This generates an error as the confirmation page cannot be viewed after closing or by anyone who didn't complete the order. How is google-adsbot finding pages to crawl that are not linked to anywhere on the site, in the sitemap or linked to anywhere else? Is there any harm in a google crawler receiving a higher percentage of errors - even though the pages are not supposed to be requested. Is there anything we can do to prevent the errors for the benefit of our network team and what are the possible risks of any measures we can take? This bot seems to be for evaluating the quality of landing pages used in for Adwords so why is it trying to access confirmation pages when they have not been set for any of our adverts? We included "Disallow: /confirmation" in the robots.txt but it has continued to request these pages, generating a 403 page and an error in the log files so it seems Adsbot doesn't follow robots.txt. Thanks in advance for any help, Sam

Is their value in linking to PPC landing pages and using rel="canonical"
I have ppc landing pages that are similar to my seo page. The pages are shorter with less text with a focus on converting visitors further along in the purchase cycle. My questions are: 1. Is there a benefit for having the orphan ppc pages indexed or should I no index them? 2. If indexing does provide benefits, should I create links from my site to the ppc pages or should I just submit them in a sitemap? 3. If indexed, should I use rel="canonical" and point the ppc versions to the appropriate organic page? Thanks,

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.

NOINDEX listing pages: Page 2, Page 3... etc?
Would it be beneficial to NOINDEX category listing pages except for the first page. For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages? Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.

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?
