I want to know why website pages are deindexed, not all but most of them are deindexed, previously their page rank of each page was 6 but after deindex they are now 0. What is happened with them, if you know then what is the procedure to getting them indexed again. I have submitted xml sitemap again in Google via webmaster tool.
Hi Daniel, I suggest you send Google a message for the reconsideration of your website. This can be done via your Google Webmaster's Tool account. They often reply if there's indeed some issues found with regards your website. Hope this helps.
It is maybe because your backlinks is spammy or your content is not quality at all. This two are some of the reasons to deindexed a website.
i see people are quickly offering their suggestion on submitting reconsideration request without even knowing why the pages were deindexed in the first place. if you don't fix the problem, then filing a reconsideration request will not help you. usually pages get deindexed for a reason. one of the main reason is copied content. if your content is not unique, then google will remove your site or pages with copied content from indexing. you first need to see if there is any page on your site with duplicate content. if there are pages like that, you will need to removed the duplicate content and replace them with unique content. once you have unique content on your site, google bot will visit your site and get those pages indexed again. there is no reason to file a reconsideration request unless your site was manually penalized by google.
Thanks for your worthy replies! I would like to tell you that in this site cannonical tag option is not used and site is running on www, www1 and www2. Can using cannonical tag will help?
