Indexed pages and current pages - Big difference?
-
Our website shows ~22k pages in the sitemap but ~56k are showing indexed on Google through the "site:" command. Firstly, how much attention should we paying to the discrepancy? If we should be worried what's the best way to find the cause of the difference?
The domain canonical is set so can't really figure out if we've got a problem or not?

Hi Nathan,
The delta between the number of pages returned by the site: operator and the number of pages in your sitemap could be down to a number of issues:
- Your XML sitemap may represent only a percentage of the total number of valid content URLs that your site is capable of generating.
a) Often sites will only generate XML sitemaps for URLs that someone has decided are "important", when the total number of URLs is much larger.
- Your XML sitemap contains ALL the valid content URLs that your site is capable of generating, but search engines are somehow finding more URLs.
a) Look in Google Webmaster Tools under Optimization >> HTML improvements >> Duplicate title tags
i) Do the pages with duplicate titles have duplicate page content? If so, your publishing platform is allowing multiple URLs to render the same content, which is a bug that needs to be fixed
b) Run a crawler like Xenu Link Sleuth or Screaming Frog against your site, and see how many URLs they discover. Export the results to Excel and look for weird URLs
i) Usually culprits for duplicate content include incorrect canonicalization (www vs non-www, URLs ending in /index.html vs just /, etc)
ii) Look for URLs ending with strange query strings (affiliate tracking, session IDs, etc)
c) Use the site: operator in other engines (Bing, blekko, etc) and compare the numbers they return. Especially if this number is larger than the number Google is returning, starting looking for weird URL patterns
Also, I'm not sure what you mean by "the domain canonical has been set correctly". If you're referring to use of the canonical link element for every URL, there are plenty of ways that can go wrong. E.g., if your CMS requires that each published URL have rel="canonical", but allows URLs to be published with and without the trailing /index.html, you can end up with a canonical link element on the non-canonical version of the URL, further confusing engines. Something to look into.

You might have a duplicate content issue. You will want to check if you have the proper 301 redirect and a canonical command in the head of your code. If you don't have this set properly then the search engines will see the www and non-www versions of your site as duplicate. Also remember that the search engines also by default place this at the end of the url /
Here are two links that can help if this is the issue.

Hope this helps. Good Luck

Yes this is a potentially significant problem. The easiest way to troubleshoot is to do the 'site:' command again, and go to the last page of results. You should be seeing pages that aren't in your sitemap. Very likely duplicated content.
If you are having a rough time troubleshooting, post a link and I'll be glad to take a peek.

Purpose of static index.html pages?
Hi All, I am fairly new to the technical side of SEO and was hoping y'all could help me better understand the purpose of dynamic rendering with index.html pages and any implications they might hold for SEO. I work to support an eComm site that includes a subdomain for its product pages: products.examplesite.com. I recently learned from one of our developers that there are actually two sets of product pages - a set of pages that he terms "reactive," that are present on our site, that only display content when a user clicks through to them and are not retrievable by search engines. And then a second set of static pages that were created just for search engines and end in .index.html. So, for example: https://products.examplesite.com/product-1/ AND https://products.examplesite.com/product-1/index.html I am confused as to what specifically the index.html pages are doing to support indexation, as they do not show up in Google Site searches, but the regular pages do. Is there something obvious I am missing here?

Over 500 thin URLs indexed from dynamically created pages (for lightboxes)
I have a client who has a resources section. This section is primarily devoted to definitions of terms in the industry. These definitions appear in colored boxes that, when you click on them, turn into a lightbox with their own unique URL. Example URL: /resources/?resource=dlna The information for these lightboxes is pulled from a standard page: /resources/dlna. Both are indexed, resulting in over 500 indexed pages that are either a simple lightbox or a full page with very minimal content. My question is this: Should they be de-indexed? Another option I'm knocking around is working with the client to create Skyscraper pages, but this is obviously a massive undertaking given how many they have. Would appreciate your thoughts. Thanks.

'duplicate content' on several different pages
Hi, I've a website with 6 pages identified as 'duplicate content' because they are very similar. This pages looks similar because are the same but it show some pictures, a few, about the product category that's why every page look alike each to each other but they are not 'exactly' the same. So, it's any way to indicate to Google that the content is not duplicated? I guess it's been marked as duplicate because the code is 90% or more the same on 6 pages. I've been reviewing the 'canonical' method but I think is not appropriated here as the content is not the same. Any advice (that is not add more content)?

How to know how much pages are indexed on Google?
I have a big site, there are a way to know what page are not indexed? I know that you can use site: but with a big site is a mess to check page by page. This is a tool or a system to check a entire site and automatically find non-indexed pages?

Https indexed...how?
Hello Moz, Since a while i am struggling with a SEO case: At the moment a https version of a homepage of a client of us is indexed in Google. Thats really strange because the url is redirected to an other website url for three weeks now. And we did everything to make clear to google that he has to index the other url.
Technical SEO | | Searchresult
So we have a few homepage urls A https://www.website.nl
B https://www.websites.nl/category
C http://www.websites.nl/category What we did: Redirected A with a 301 to B, a redirect from A or B to C is difficult because of the security issue with the ssl certificate. We put the right canonical url (VERSION C) on every version of the homepage(A,B) We only put the canonical urls in the sitemap.xml, only version C and uploaded it to Google Webmastertools We changed all important internal links to Version C We also get some valuable external backlinks to Version C Is there something i missed or i forget to say to Google hey look you've got the wrong url indexed, you have to index version C? How is it possible Google still prefers Version A after doing al those changes three weeks a go? I'am really looking forward to your answer. Thanks a lot in advanced! Greetz Djacko0 -
What is the best practice to re-index the de-indexed pages due to a bad migration
Dear Mozers, We have a Drupal site with more than 200K indexed URLs. Before 6 months a bad website migration happened without proper SEO guidelines. All the high authority URLs got rewritten by the client. Most of them are kept 404 and 302, for last 6 months. Due to this site traffic dropped more than 80%. I found today that around 40K old URLs with good PR and authority are de-indexed from Google (Most of them are 404 and 302). I need to pass all the value from old URLs to new URLs. Example URL Structure

(Page Authority: 65, HTTP Status:404, De-indexed from Google) After Migration (Current)
http://www.domain.com/new-indexed-and-live-url-version Does creating mass 301 redirects helps here without re-indexing the old URLS? Please share your thoughts. Riyas0 -
Duplicate pages in Google index despite canonical tag and URL Parameter in GWMT
Good morning Moz... This is a weird one. It seems to be a "bug" with Google, honest... We migrated our site www.three-clearance.co.uk to a Drupal platform over the new year. The old site used URL-based tracking for heat map purposes, so for instance www.three-clearance.co.uk/apple-phones.html ..could be reached via www.three-clearance.co.uk/apple-phones.html?ref=menu or www.three-clearance.co.uk/apple-phones.html?ref=sidebar and so on. GWMT was told of the ref parameter and the canonical meta tag used to indicate our preference. As expected we encountered no duplicate content issues and everything was good. This is the chain of events: Site migrated to new platform following best practice, as far as I can attest to. Only known issue was that the verification for both google analytics (meta tag) and GWMT (HTML file) didn't transfer as expected so between relaunch on the 22nd Dec and the fix on 2nd Jan we have no GA data, and presumably there was a period where GWMT became unverified. URL structure and URIs were maintained 100% (which may be a problem, now) Yesterday I discovered 200-ish 'duplicate meta titles' and 'duplicate meta descriptions' in GWMT. Uh oh, thought I. Expand the report out and the duplicates are in fact ?ref= versions of the same root URL. Double uh oh, thought I. Run, not walk, to google and do some Fu: http://is.gd/yJ3U24 (9 versions of the same page, in the index, the only variation being the ?ref= URI) Checked BING and it has indexed each root URL once, as it should. Situation now: Site no longer uses ?ref= parameter, although of course there still exists some external backlinks that use it. This was intentional and happened when we migrated. I 'reset' the URL parameter in GWMT yesterday, given that there's no "delete" option. The "URLs monitored" count went from 900 to 0, but today is at over 1,000 (another wtf moment) I also resubmitted the XML sitemap and fetched 5 'hub' pages as Google, including the homepage and HTML site-map page. The ?ref= URls in the index have the disadvantage of actually working, given that we transferred the URL structure and of course the webserver just ignores the nonsense arguments and serves the page. So I assume Google assumes the pages still exist, and won't drop them from the index but will instead apply a dupe content penalty. Or maybe call us a spam farm. Who knows. Options that occurred to me (other than maybe making our canonical tags bold or locating a Google bug submission form 😄 ) include A) robots.txt-ing .?ref=. but to me this says "you can't see these pages", not "these pages don't exist", so isn't correct B) Hand-removing the URLs from the index through a page removal request per indexed URL C) Apply 301 to each indexed URL (hello BING dirty sitemap penalty) D) Post on SEOMoz because I genuinely can't understand this. Even if the gap in verification caused GWMT to forget that we had set ?ref= as a URL parameter, the parameter was no longer in use because the verification only went missing when we relaunched the site without this tracking. Google is seemingly 100% ignoring our canonical tags as well as the GWMT URL setting - I have no idea why and can't think of the best way to correct the situation. Do you? 🙂 Edited To Add: As of this morning the "edit/reset" buttons have disappeared from GWMT URL Parameters page, along with the option to add a new one. There's no messages explaining why and of course the Google help page doesn't mention disappearing buttons (it doesn't even explain what 'reset' does, or why there's no 'remove' option).
