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.

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

Would You Redirect a Page if the Parent Page was Redirected?
Hi everyone! Let's use this as an example URL: https://www.example.com/marvel/avengers/hulk/ We have done a 301 redirect for the "Avengers" page to another page on the site. Sibling pages of the "Hulk" page live off "marvel" now (ex: /marvel/thor/ and /marvel/iron-man/). Is there any benefit in doing a 301 for the "Hulk" page to live at /marvel/hulk/ like it's sibling pages? Is there any harm long-term in leaving the "Hulk" page under a permanently redirected page? Thank you! Matt

Page rank and menus
Hi, My client has a large website and has a navigation with main categories. However, they also have a hamburger type navigation in the top right. If you click it it opens to a massive menu with every category and page visible. Do you know if having a navigation like this bleeds page rank? So if all deep pages are visible from the hamburger navigation this means that page rank is not being conserved to the main categories. If you click a main category in the main navigation (not the hamburger) you can see the sub pages. I think this is the right structure but the client has installed this huge menu to make it easier for people to see what there is. From a technical SEO is this not bad?

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

Mobile Googlebot vs Desktop Googlebot - GWT reports - Crawl errors
Hi Everyone, I have a very specific SEO question. I am doing a site audit and one of the crawl reports is showing tons of 404's for the "smartphone" bot and with very recent crawl dates. If our website is responsive, and we do not have a mobile version of the website I do not understand why the desktop report version has tons of 404's and yet the smartphone does not. I think I am not understanding something conceptually. I think it has something to do with this little message in the Mobile crawl report. "Errors that occurred only when your site was crawled by Googlebot (errors didn't appear for desktop)." If I understand correctly, the "smartphone" report will only show URL's that are not on the desktop report. Is this correct?

Putting "noindex" on a page that's in an iframe... what will that mean for the parent page?
If I've got a page that is being called in an iframe, on my homepage, and I don't want that called page to be indexed.... so I put a noindex tag on the called page (but not on the homepage) what might that mean for the homepage? Nothing? Will Google, Bing, Yahoo, or anyone else, potentially see that as a noindex tag on my homepage?
