Huge google index with un-relevant pages
-
Hi,
i run a site about sport matches, every match has a page and the pages are generated automatically from the DB. pages are not duplicated, but over time some look a little bit similar. after a match finishes it has no internal links or sitemap entry, but it's reachable by direct URL and continues to be on google index. so over time we have more than 100,000 indexed pages.
since past matches have no significance and they're not linked and a match can repeat and it may look like duplicate content....what you suggest us to do:
when a match is finished - not linked, but appears on the index and SERP
-
301 redirect the match Page to the match Category which is a higher hierarchy and is always relevant?
-
use rel=canonical to the match Category
-
do nothing....
*301 redirect will shrink my index status, some say a high index status is good...
*is it safe to 301 redirect 100,000 pages at once - wouldn't it look strange to google?
*would canonical remove the past matches pages from the index?
what do you think?
Thanks,
Assaf.

In terms of what you've written, blocking a page via robots.txt doesn't remove it from the index. It simply prevents the crawlers from reaching the page. So if you block a page via robots.txt, the page remains in the index, Google just can't go back to the page and see if anything has changed. So if you were to block the page via robots.txt, and add a noindex tag to the page, Google won't be able to see the page with the noindex tag to remove it from the index because it's blocked via robots.txt.
If you moved all of your old content to a different folder, and block that folder via robots.txt, Google won't remove those pages from the index. In order to remove them from the index, you would have to go in to Webmaster Tools and use the URL removal tool to remove that new folder from the index - if they see it's blocked via robots.txt, then and only then they'll remove the content from the index - it has to be blocked via robots.txt first in order to remove the whole folder with the URL removal tool.
I'm not sure though if this would work for the future - if you removed a folder from the index, and then added more content that was indexed previously afterwards, I'm not sure what would happen to that new content moved to that folder. Either way, Google will have to come back and recrawl the page to see that it has moved to the new folder, and then remove it from the index. So either way, the content will only be removed once Google recrawls the old content.
So I still think a better way to remove the content from the index is to add the noindex tag to the old pages. To facilitate the search engines reaching these old pages, I'd make sure there is a way the engines can get to them - make sure there is a path they can take to reach them.
Another good idea I saw on a forum post here a while ago would be to create a sitemap containing all of these old pages you have indexed and want removed. Add the noindex tag to the sitemap - using the Webmaster tools sitemap interface, you'll then be able to monitor the progress of deindexation over time - by checking how many pages on the sitemap/s of the old content are originally indexed as reported by webmaster tools, and then you can see later on how many of those pages are still indexed, this will be a good indicator for you of the progress of the deindexation.

Dear Mark,
*i've sent you a private message.
i'm starting to understand i've a much bigger problem.
*my index status contain 120k pages while only 2000 are currently relevant.
your suggestion is - after a match finishes pragmatically add to the page and google will remove it from it's index. it could work for relatively new pages but since very old pages don't have links OR sitemap entry it could take a very long time to clear the index cause they're rarely crawled - if at all.
- more aggressive approach would be to change this site architecture and restrict by robot.txt the folder that holds all the past irrelevant pages.
so if today a match URL is like this: www.domain.com/sport/match/T1vT2
restrict www.domain.com/sport/match/ on robots.txt
and from now on create all new matches on different folder like: www.domain.com/sport/new-match-dir/T1vT2
-
is this a good solution?
-
wouldn't google penalize me for removing a directory with 100k pages?
-
if it's a good approach, how much time it will take for google to clear all those pages from it's index?
I know it's a long one and i'll really appreciate your response.
Thanks a lot,
Assaf.

there are a bunch of articles out there, but each case is different - here are a few:

You can contact me via private message here on the forum and I can try to take a more in depth look at your site if you can give me some more detailed info.

yes. when the 1st Panda update was rolled out i've lost 50% of the traffic from google and haven't really recovered since.
-
Are you sure you got hit by Panda before we talk about a Panda hit?
-
Thanks Mark!
any good article about how to recover from Panda?
-
Exactly - I'd build a strategy more around promoting pages that will have long lasting value.
If you use the tag noindex, follow, it will continue to spread link juice throughout the site, it's just the individual page with the tag will not be included in the search results and will not be part of the index. In order for the tag to work, they first have to crawl the page and see the tag - so it doesn't happen instantaneously - if they crawl these deeper pages once every few weeks, once a month, or even longer, it may take a while for these pages to be removed from the index.

Hi Mark
-
these pages are very important when they are relevant (before the match finished) - they are the source of most of our traffic which come from long tail searches.
-
some of these pages have inbound link and it would be a shame to lose all this juice.
-
would noindex remove the pages from the google index? how much time it would take? wouldn't a huge noindex also look suspicious?
-
by "evergreen pages" - you mean pages that are always relevant like League page / Sport page etc...?
Thanks,
Assaf.

Hi Assaf,
(I'm not stalking you, I just think you've raised another interesting question)
In terms of index status/size, you don't want to create a massive index of empty/low value pages - this is food for Google's Panda algorithm, and will not be good for your site in the long run. It'll get a Panda smack if it hasn't already.
To remove these pages from the index, instead of doing hundreds of thousands of 301 redirects, which your server won't like either, I'd recommend adding the noindex meta tag to the pages.
I'd put a rule in your cms that after a certain point in time, you noindex those pages. Make sure you also have evergreen pages on your site that can serve as landing pages for the search engines and which won't need to be removed after a short period of time. These are the pages you'll want to focus your outreach and link building efforts on.

Why does Google display the home page rather than a page which is better optimised to answer the query?
I have a page which (I believe) is well optimised for a specific keyword (URL, title tag, meta description, H1, etc). yet Google chooses to display the home page instead of the page more suited to the search query. Why is Google doing this and what can I do to stop it?

How to 301 Redirect /page.php to /page, after a RewriteRule has already made /page.php accessible by /page (Getting errors)
A site has its URLs with php extensions, like this: example.com/page.php I used the following rewrite to remove the extension so that the page can now be accessed from example.com/page RewriteCond %{REQUEST_FILENAME}.php -f
Intermediate & Advanced SEO | | rcseo
RewriteRule ^(.*)$ $1.php [L] It works great. I can access it via the example.com/page URL. However, the problem is the page can still be accessed from example.com/page.php. Because I have external links going to the page, I want to 301 redirect example.com/page.php to example.com/page. I've tried this a couple of ways but I get redirect loops or 500 internal server errors. Is there a way to have both? Remove the extension and 301 the .php to no extension? By the way, if it matters, page.php is an actual file in the root directory (not created through another rewrite or URI routing). I'm hoping I can do this, and not just throw a example.com/page canonical tag on the page. Thanks!0 -
Handling pages that are no longer relevant (both permanently and temporarily)
Hi, We run a travel site with a number of programs, and each program has its own dedicate page, ie example.com/programs/program-xyz Some of these programs stop running and we no longer offer them, other-times they are on hold and will be reactivated later. Our old strategy was to 301-redirect these programs to another, relevant program. However, I believe that could be flawed. Would it not be a better solution to display the page as normal (with a 200 code) and instead of having the details of the program rather show some text saying the program has stopped and list a few suggestions. I just don't want to set off any spam-flags by pushing SE value via a 301 redirect to unrelated pages Here are some other scenarios I was thinking: For the program are only temporarily on-hold (ie not taking bookings for now) 302 redirect those to more appropriate pages For programs that are permanently on-hold (ie will never take bookings again) show a custom 404 or 410 page (With text with suggestions of different programs) Any suggestions or feedback on this would be most appreciated. -Jason

How is Google crawling and indexing this directory listing?
We have three Directory Listing pages that are being indexed by Google: http://www.ccisolutions.com/StoreFront/jsp/ http://www.ccisolutions.com/StoreFront/jsp/html/ http://www.ccisolutions.com/StoreFront/jsp/pdf/ How and why is Googlebot crawling and indexing these pages? Nothing else links to them (although the /jsp.html/ and /jsp/pdf/ both link back to /jsp/). They aren't disallowed in our robots.txt file and I understand that this could be why. If we add them to our robots.txt file and disallow, will this prevent Googlebot from crawling and indexing those Directory Listing pages without prohibiting them from crawling and indexing the content that resides there which is used to populate pages on our site? Having these pages indexed in Google is causing a myriad of issues, not the least of which is duplicate content. For example, this file <tt>CCI-SALES-STAFF.HTML</tt> (which appears on this Directory Listing referenced above - http://www.ccisolutions.com/StoreFront/jsp/html/) clicks through to this Web page: http://www.ccisolutions.com/StoreFront/jsp/html/CCI-SALES-STAFF.HTML This page is indexed in Google and we don't want it to be. But so is the actual page where we intended the content contained in that file to display: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff As you can see, this results in duplicate content problems. Is there a way to disallow Googlebot from crawling that Directory Listing page, and, provided that we have this URL in our sitemap: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff, solve the duplicate content issue as a result? For example: Disallow: /StoreFront/jsp/ Disallow: /StoreFront/jsp/html/ Disallow: /StoreFront/jsp/pdf/ Can we do this without risking blocking Googlebot from content we do want crawled and indexed? Many thanks in advance for any and all help on this one!

404'd pages still in index
I recently launched a site and shortly after performed a URL rewrite (not the greatest idea, i know). The developer 404'd the old pages instead of a permanent 301 redirect. This caused a mess in the index. I have tried to use Google's removal tool to remove these URL's from the index. These pages were being removed but now I am finding them in the index as just URL's to the 404'd page (i.e. no title tag or meta description). Should I wait this out or now go back and 301 redirect the old URL's (that are 404'd now) to the new URL's? I am sure this is the reason for my lack of ranking as the rest of my site is pretty well optimized and I have some quality links.

Will Google Visit Non-Canonicalized Page Again and Return Its Page's Original Ranking?
I have 2 questions about canonicalization. 1. Will Google ever visit Page A again if after it has been canonicalized to Page B? 2. If Google will still visit Page A and found that it is not canonicalizing to Page B already, will the original rankings and traffic of Page A returned to the way before it's canonicalized? Thanks.

Should I prevent Google from indexing blog tag and category pages?
I am working on a website that has a regularly updated Wordpress blog and am unsure whether or not the category and tag pages should be indexable. The blog posts are often outranked by the tag and category pages and they are ultimately leaving me with a duplicate content issue. With this in mind, I assumed that the best thing to do would be to remove the tag and category pages from the index, but after speaking to someone else about the issue, I am no longer sure. I have tried researching online, but there isn't anything that provided any further information. Please can anyone with any experience of dealing with issues like this or with any knowledge of the topic help me to resolve this annoying issue. Any input will be greatly appreciated. Thanks Paul

Should I Allow Blog Tag Pages to be Indexed?
I have a wordpress blog with settings currently set so that Google does not index tag pages. Is this a best practice that avoids duplicate content or am I hurting the site by taking eligible pages out of the index?
