Welcome to the Q&A Forum

Hi, I'm having a problem I cannot solve about duplicate article postings. As you will see from the attached images, I have a page with multiple variants of the same URL in google index and as well as duplicate title tag in the search console of webmasters tools. Its been several months I have been using canonical meta tags to resolve the issue, aka declare all variants to point to a single URL, however the problem remains. Its not just old articles that stay like that, even new articles show the same behaviour right when they are published even thought they are presented correctly with canonical links and sitemap as you will see from the example bellow. Example URLs of the attached Image All URLs belonging to the same article ID, have the same canonical link inside the html head. Also because I have a separate mobile site, I also include in every desktop URL an "alternate" link to the mobile site. At the Mobile Version of the Site, I have another canonical link, pointing back to the original Desktop URL. So the mobile site article version also has Now, when it comes to the xml sitemap, I pass only the canonical URL and none of the other possible variants (to avoid multiple indexing), and I also point to the mobile version of the article.

The main sitemap of the website: http://www.neakriti.gr/WebServices/sitemap-index.aspx Despite my efforts you see that webmasters tools reports three variants for the desktop URL, and google search reports 4 URLs (3 different desktop variant urls and the mobile url). I get this when I type the article code to see if what is indexed in google search: site:neakriti.gr 1300297 So far I believe I have done all I could in order to resolve the issue by addressing canonical links and alternate links, as well as correct sitemap.xml entry.  I don't know what else to do... This was done several months ago and there is absolutelly no improvement. Here is a more recent example of an article added 5 days ago (10-April-2016), just type
site:neakriti.gr 1300357
at google search and you will see the variants of the same article in google cache.  Open the google cached page, and you will see the cached pages contain canonical link, but google doesn't obey the direction given there. Please help! duplicate-articles.jpg duplicate-articles-in-index.jpg

Hi, I am trying to cleanse a news website.  When this website was first made, the people that set it up copied all kinds of articles they had as a newspaper, including tests, internal communication, and drafts.  This site has lots of junk, but this kind of junk was on the initial backup, aka before 1st-June-2012.  So, removing all mixed content prior to that date, we can have pure articles starting June 1st, 2012! Therefore My dynamic sitemap now contains only articles with release date between 1st-June-2012 and now Any article that has release date prior to 1st-June-2012 returns a custom 404 page with "noindex" metatag, instead of the actual content of the article. The question is how I can remove from the google index all this junk as fast as possible that is not on the site anymore, but still appears in google results? I know that for individual URLs I need to request removal from this link
https://www.google.com/webmasters/tools/removals The problem is doing this in bulk, as there are tens of thousands of URLs I want to remove.  Should I put the articles back to the sitemap so the search engines crawl the sitemap and see all the 404?  I believe this is very wrong.  As far as I know this will cause problems because search engines will try to access non existent content that is declared as existent by the sitemap, and return errors on the webmasters tools. Should I submit a DELETED ITEMS SITEMAP using the <expires>tag? I think this is for custom search engines only, and not for the generic google search engine.
https://developers.google.com/custom-search/docs/indexing#on-demand-indexing</expires> The site unfortunatelly doesn't use any kind of "folder" hierarchy in its URLs, but instead the ugly GET params, and a kind of folder based pattern is impossible since all articles (removed junk and actual articles) are of the form:
http://www.example.com/docid=123456 So, how can I bulk remove from the google index all the junk... relatively fast?
