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.

Few pages without SSL
Hi, A website is not fully secured with a SSL certificate.
Intermediate & Advanced SEO | | AdenaSEO
Approx 97% of the pages on the website are secured. A few pages are unfortunately not secured with a SSL certificate, because otherwise some functions on those pages do not work. It's a website where you can play online games. These games do not work with an SSL connection. Is there anything we have to consider or optimize?
Because, for example when we click on the secure lock icon in the browser, the following notice.
Your connection to this site is not fully secured Can this harm the Google ranking? Regards,

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

Merging Pages and SEO
Hi, We are redesigning our website the following way: Before: Page A with Content A, Page B with Content B, Page C with Content C, etc
Intermediate & Advanced SEO | | viatrading1
e.g. one page for each Customer Returns, Overstocks, Master Case, etc
Now: Page D with content A + B + C etc.
e.g. one long page containing all Product Conditions, one after the other So we are merging multiples pages into one.
What is the best way to do so, so we don't lose traffic? (or we lose the minimum possible) e.g. should we 301 Redirect A/B/C to D...?
Is it likely that we lose significant traffic with this change? Thank you,0 -
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 -
Different Header on Home Page vs Sub pages
Hello, I am an SEO/PPC manager for a company that does a medical detox. You can see the site in question here: http://opiates.com. My question is, I've never heard of it specifically being a problem to have a different header on the home page of the site than on the subpages, but I rarely see it either. Most sites, if i'm not mistaken, use a consistent header across most of the site. However, a person i'm working for now said that she has had other SEO's look at the site (above) and they always say that it is a big SEO problem to have a different header on the homepage than on the subpages. Any thoughts on this subject? I've never heard of this before. Thanks, Jesse

How long takes to a page show up in Google results after removing noindex from a page?
Hi folks, A client of mine created a new page and used meta robots noindex to not show the page while they are not ready to launch it. The problem is that somehow Google "crawled" the page and now, after removing the meta robots noindex, the page does not show up in the results. We've tried to crawl it using Fetch as Googlebot, and then submit it using the button that appears. We've included the page in sitemap.xml and also used the old Google submit new page URL https://www.google.com/webmasters/tools/submit-url Does anyone know how long will it take for Google to show the page AFTER removing meta robots noindex from the page? Any reliable references of the statement? I did not find any Google video/post about this. I know that in some days it will appear but I'd like to have a good reference for the future. Thanks.

Can too many "noindex" pages compared to "index" pages be a problem?
Hello, I have a question for you: our website virtualsheetmusic.com includes thousands of product pages, and due to Panda penalties in the past, we have no-indexed most of the product pages hoping in a sort of recovery (not yet seen though!). So, currently we have about 4,000 "index" page compared to about 80,000 "noindex" pages. Now, we plan to add additional 100,000 new product pages from a new publisher to offer our customers more music choice, and these new pages will still be marked as "noindex, follow". At the end of the integration process, we will end up having something like 180,000 "noindex, follow" pages compared to about 4,000 "index, follow" pages. Here is my question: can this huge discrepancy between 180,000 "noindex" pages and 4,000 "index" pages be a problem? Can this kind of scenario have or cause any negative effect on our current natural SEs profile? or is this something that doesn't actually matter? Any thoughts on this issue are very welcome. Thank you! Fabrizio

301 - should I redirect entire domain or page for page?
Hi, We recently enabled a 301 on our domain from our old website to our new website. On the advice of fellow mozzer's we copied the old site exactly to the new domain, then did the 301 so that the sites are identical. Question is, should we be doing the 301 as a whole domain redirect, i.e. www.oldsite.com is now > www.newsite.com, or individually setting each page, i.e. www.oldsite.com/page1 is now www.newsite.com/page1 etc for each page in our site? Remembering that both old and new sites (for now) are identical copies. Also we set the 301 about 5 days ago and have verified its working but haven't seen a single change in rank either from the old site or new - is this because Google hasn't likely re-indexed yet? Thanks, Anthony
