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.

Fresh page versus old page climbing up the rankings.
Hello, I have noticed that if publishe a webpage that google has never seen it ranks right away and usually in a descend position to start with (not great but descend). Usually top 30 to 50 and then over the months it slowly climbs up the rankings. However, if my page has been existing for let's say 3 years and I make changes to it, it takes much longer to climb up the rankings Has someone noticed that too ? and why is that ?

My landing pages don't show up in the SERPs, only my frontpage does.
I am having some trouble with getting the landing pages for a clients website to show up in the SERPs.
Intermediate & Advanced SEO | | InmediaDK
As far as I can see, the pages are optimized well, and they also get indexed by Google. The website is a danish webshop that sells wine, www.vindanmark.com Take for an instance this landing page, http://www.vindanmark.com/vinhandel/
It is optimzied for the keywords "Vinhandel Århus". Vinhandel means "Winestore" and "Århus" is a danish city. As you can see, I manage to get them at page 1 (#10), but it's the frontpage that ranks for the keyword. And this goes for alle the other landing pages as well. But I can't figure out, why the frontpage keep outranking the landingpages on every keyword.
What am I doing wrong here?1 -
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 -
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

Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks

Blocking Pages Via Robots, Can Images On Those Pages Be Included In Image Search
Hi! I have pages within my forum where visitors can upload photos. When they upload photos they provide a simple statement about the photo but no real information about the image,definitely not enough for the page to be deemed worthy of being indexed. The industry however is one that really leans on images and having the images in Google Image search is important to us. The url structure is like such: domain.com/community/photos/~username~/picture111111.aspx I wish to block the whole folder from Googlebot to prevent these low quality pages from being added to Google's main SERP results. This would be something like this: User-agent: googlebot Disallow: /community/photos/ Can I disallow Googlebot specifically rather than just using User-agent: * which would then allow googlebot-image to pick up the photos? I plan on configuring a way to add meaningful alt attributes and image names to assist in visibility, but the actual act of blocking the pages and getting the images picked up... Is this possible? Thanks! Leona

There's a website I'm working with that has a .php extension. All the pages do. What's the best practice to remove the .php extension across all pages?
Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.
