Why is my Crawl Report Showing Thousands of Pages that Do Not Exist?
-
Hi,
I just downloaded a Crawl Summary Report for a client's website. I am seeing THOUSANDS of duplicate page content errors. The overwhelming majority of them look something like this:
This page doesn't exist and results in a 404 page. Why are these pages showing up? How do I get rid of them? Are they endangering the health of my site as a whole?
Thank you,
Jenna

Hi Jenna,
It's not so much the fact you have 404 pages that is the problem for SEO, but rather the fact your site is creating a problem for the search engines to crawl the site correctly and efficiently since they are getting caught in an endless loop. This can be a problem because the crawlers may get caught in the endless loop and just give up on your site and leave, which means the search engines may not be able to access the rest of the pages on your site and may have a negative impact on your rankings as a whole. One of the most important parts of SEO is to make your website as "friendly" to the search engines as possible so if they caught in endless loops then that is definitely not ideal. Hope that helps!

Hi Streamline -
Thanks for your help thus far. Could you elaborate on some of the SEO challenges this presents? After a bit of research, I'm seeing people say that having hundreds or thousands of 404s are okay, if they are in fact non-existant pages. I'm not that well educated on this, so just looking for a bit of clarification.
I will look into the relative URL issue. I just recently took over the work on this site, and I'm still digging in to what the original web developer created.

It looks like the crawler is being caught in an endless loop, most likely a result of using relative URLs somewhere on your site. Yes, this is a problem for the site as a whole so I highly recommend implementing absolute URLs throughout the entire site.
Edit - I just looked at your site and this is exactly what it is. The links in your navigation are relative, such as "<a <="" span="">href="</a>../development/default.aspx"" so just change it to absolute URLs such as http://www.yoursite.com/development/default.aspx and it should fix the problem.

Should I apply Canonical Links from my Landing Pages to Core Website Pages?
I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

If a page ranks in the wrong country and is redirected, does that problem pass to the new page?
Hi guys, I'm having a weird problem: A new multilingual site was launched about 2 months ago. It has correct hreflang tags and Geo targetting in GSC for every language version. We redirected some relevant pages (with good PA) from another website of our client's. It turned out that the pages were not ranking in the correct country markets (for example, the en-gb page ranking in the USA). The pages from our site seem to have the same problem. Do you think they inherited it due to the redirects? Is it possible that Google will sort things out over some time, given the fact that the new pages have correct hreflangs? Is there stuff we could do to help ranking in the correct country markets?

What are best page titles for sub-domain pages?
Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

Redirecting homepage to internal page (2nd Tier page)
We are planning to experiment redirecting our homepage to one of the 2nd tier page. I mean....example.com to example.com/page. We need this page to rank well, but it doesn't have much internal links or external back-links, so we opt for this redirect. Advantage with this page is, it has "keyword" we want to rank for in URL. "page" in example.com/page. Will this help or hurt us in SEO? I think we are missing keyword in our root domain, so interested to highlight this page. Thanks, Satish

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

Why does Google rank a product page rather than a category page?
Hi, everybody In the Moz ranking tool for one of our client's (the client sells sport equipment) account, there is a trend where more and more of their landing pages are product pages instead of category pages. The optimal landing page for the term "sleeping bag" is of course the sleeping bag category page, but Google is sending them to a product page for a specific sleeping bag.. What could be the critical factors that makes the product page more relevant than the category page as the landing page?

Would you rate-control Googlebot? How much crawling is too much crawling?
One of our sites is very large - over 500M pages. Google has indexed 1/8th of the site - and they tend to crawl between 800k and 1M pages per day. A few times a year, Google will significantly increase their crawl rate - overnight hitting 2M pages per day or more. This creates big problems for us, because at 1M pages per day Google is consuming 70% of our API capacity, and the API overall is at 90% capacity. At 2M pages per day, 20% of our page requests are 500 errors. I've lobbied for an investment / overhaul of the API configuration to allow for more Google bandwidth without compromising user experience. My tech team counters that it's a wasted investment - as Google will crawl to our capacity whatever that capacity is. Questions to Enterprise SEOs: *Is there any validity to the tech team's claim? I thought Google's crawl rate was based on a combination of PageRank and the frequency of page updates. This indicates there is some upper limit - which we perhaps haven't reached - but which would stabilize once reached. *We've asked Google to rate-limit our crawl rate in the past. Is that harmful? I've always looked at a robust crawl rate as a good problem to have. Is 1.5M Googlebot API calls a day desirable, or something any reasonable Enterprise SEO would seek to throttle back? *What about setting a longer refresh rate in the sitemaps? Would that reduce the daily crawl demand? We could set increase it to a month, but at 500M pages Google could still have a ball at the 2M pages/day rate. Thanks

Hreflang and paginated page
Hi, I can not seem to find good documentation about the use of hreflang and paginated page when using rel=next , rel=prev
Intermediate & Advanced SEO | | TjeerdvZ
Does any know where to find decent documentatio?, I could only find documentation about pagination and hreflang when using canonicals on the paginated page. I have doubts on what is the best option: The way tripadvisor does it:
http://www.tripadvisor.nl/Hotels-g187139-oa390-Corsica-Hotels.html
Each paginated page is referring to it's hreflang paginated page, for example: So should the hreflang refer to the pagined specific page or should it refer to the "1st" page? in this case:
http://www.tripadvisor.nl/Hotels-g187139-Corsica-Hotels.html Looking foward to your suggestions.0
