Short Question: What's the best way to get Google to re-index duplicate URLs?
Long Story:
We have a long ago (1997) established website with a proprietary CMS. Never paid much attention to SEO (other than creating a sitemap) until four months ago. After learning some we started modifying the engine to provide better site to google (proper HTTP codes, consistent URLs to eliminate duplicates - we had something like 15,000 duplicates - etc...)
Things went great for three and half months and we reached the first page on google for our main keyword (very, very competitive keyword). Before the SEO we were getting around 25,000 impressions and 3000 clicks on google. After our SEO efforts, we reached 70,000 daily impressions and more than 7000 daily clicks.
On Aug 30th, 2014, one of our programmers committed a change to the live server by mistake. This small change effectively changed every article's URL by adding either a dash at its end or a dash and a keyword '-test-keyword' (literally).
Nobody noticed anything until two days later as the site worked perfectly for humans. The result of this small code change is that within five days our site practically disappeared from Google's results pages except when one searched for our site's name. Our rank dropped from 8 and 10 to 80 and 100 for our main keywords.
We reverted the change as soon as we noticed the problem, but during those two days, Google's bots went on a binge crawling five times the usual number of page crawled per day.
We've been trying to recover and nothing seems to be working so far. Google's bots aren't crawling the repaired URLs to get the 301 headers back to the original URL and now we still have over 2300 duplicates as reported by the webmaster tools.
Our Google impressions and clicks dropped to way below what we had before we did any SEO, down to 5000 impressions and 1200 clicks (inclusive of our direct domain name search).
During the last 15 days (after we fixed the problem), our duplicate count went from a maximum of 3200, down to 1200, then back up to 2300 without any changes on our end.
we've redone our sitemap and resubmitted it on day 3.
So, what do we do? Do we go through the URLs with 'fetch as Google' function? (that's a bit tedious for 2300 URLs) or we wait for the bots to come around whenever they feel like it? if we do this, should we submit the bad URL, have google fetch it, get the redirect, follow it and then submit the followed URL to the index?
Or is there a better solution that I'm unaware of?
Second question: Is this something to be expected when something like this happens knowing that our inbound link rarely link to the actual articles?
-
Well, after submitting multiple temporary sitemaps and having Google index them, our duplicate counts dropped back to pre-event levels.
However, our rankings haven't improved at all. Actually, if anything, they dropped even further.
At this point it's really starting to look like this is a hit from Panda 4.1 and that we had our URLs change was merely a coincidence. From the looks of it, Google is now marking our site as a low quality site. Now that we know about such a thing, we definitely experienced a 'sinister surge' prior to disaster striking.
Since we've never engaged in any bad behavior on the site and we've always followed google's best practice advice, we're currently at a loss of what could be the reason that we're hit that way. Our content is fresh and high quality (arguably the highest quality in our domain), we have a very decent link profile according to MajesticSEO, so for now, no clue about what's going on really.
Attached is the site's impressions and clicks graph from Webmaster Tools.

["knowing that our inbound link rarely link to the actual articles" --> not sure I follow.]
I asked whether it's normal for all ranking to drop even for unaffected pages when pages with no inbound link have issues. For example, our top ranked page for our main keyword didn't change in anyway, not its URL, its description nor its title, yet it's rank tanked after this event.
I like the temporary sitemap idea. Thanks.

Once you have all the 301 redirects set up, create a sitemap with all of the old urls and submit that. Google will crawl them and see that they are now 301 redirects and process the data faster. then delete the sitemap.
You should also have a canonical tag on the article pages with the new/current link that should be indexed.
"knowing that our inbound link rarely link to the actual articles" --> not sure I follow.
In general, your rankings should bounce back once google picks up on all of the fixes.

Site went down and traffic hasn't recovered
Very curious situation. We have a network of sites. Sunday night one (only one) of our sites goes down, and since then we've seen a loss in traffic across all our sites!! Not only have we seen a loss of traffic, we also saw a loss of indexed pages. A complete drop off from 1.8 million to 1.3 million pages indexed. Does anyone know why one site outtage would affect the rest of them? And the indexed pages? Very confused. Thanks,

Home Page Deindexed Only at Google after Recovering from Hack Attack
Hello, Facing a Strange issue, wordpress blog hghscience[dot]com was hacked by someone, when checked, I found index.php file was changed & it was showing some page with a hacked message, & also index.html file was added to the cpanel account.All pages were showing same message, when I found it, I replaced index.php to default wordpress index.php file & deleted index.htmlI could not find any other file which was looking suspicious. Site started working fine & it was also indexed but cached version was that hacked page. I used webmaster tool to fetch & render it as google bot & submitted for indexing. After that I noticed home page get deindexed by google. Rest all pages are indexing like before. Site was hacked around 30th July & I fixed it on 1st Aug. Since then home page is not getting indexed, I tried to fetch & index multiple time via google webmasters tool but no luck as of now. 1 More thing I Noticed, When I used info:mysite.com on google, its showing some other hacked site ( www.whatsmyreferer.com/ ) When Searching from India But when same info:mysite.com is searched from US a different hacked site is showing ( sigaretamogilev.by )However when I search "mysite.com" my site home page is appearing on google search but when I check cached URL its showing hacked sites mentioned above.As per my knowledge I checked all SEO Plugins, Codes of homepage, can't find anything which is not letting the homepage indexed.PS: webmaster tool has received no warning etc for penalty or malware. I also noticed I disallowed index.php file via robots.txt earlier but now I even removed that. 7Dj1Q0w.png 3krfp9K.png

Redesiging website and how to prevent a SEO disaster?
Hey guys, I'm in the process of re designing my company website. This website runs in Kentico CMS and now I'm moving to drupal CMS. The main reason for the move is that I need a more flexible design with responsiveness and integrate better social aspects. Currently I'm having to deal with a developer whom can't be bothered to update the site. I also find kentico extremely difficult to deal with. The site has good Google rankings and I was thinking about setting up some 301 redirects when the move is completed. Now the question is this site is been live for over 2 years and I have tons of blog posts sitting in here. How can I get these moved? When this is done will they lose their 'age' ? What if I re create the blog posts as it is and then setup 301 re-directs on this? I have G+ authorship and will they be affected by this? Last question is having a responsive site will affect my SEO rankings once moved? I heard the 301 is not considered as a 'safe' thing with Google so what are my options? If anyone can share a link(s) to site upgrades/moving to new design tutorials/best practices articles based on SEO ill be grateful. Thank you very much.

Traffic stats disaster
Hi, We have recently moved a few old websites to an existing one and redesigned the existing website too. The visits in Analytics have fallen though the roof in the last few days. I would expect the traffic to have gone up because visitors from the old websites should now be on the redesigned one. Not sure what the problem is entirely. GA code is on the site but not before the closing head where I asked for it to be put. It's just before closing body tag. Does it make a difference? (It's a CMS site). GA code must be working because visits are being recorded (tens rather than the expected hundreds). Redirects have not been done properly - not sure what IT have done there. Would the lack of proper redirects be the sole reason for the drop? I am still hassling for 301's to be sorted. Thanks all

How to recover from duplicate subdomain penalty?
Two and half a weeks ago, my site was slapped with a penalty -- 60% of organic traffic disappeared over 2-3 days. After investigating we discovered that our site was serving the same content for all subdomains, and Google somehow had two additional subdomains it was crawling and indexing. We solved the issue with 301 redirects to our main site (www) a couple of days after the drop -- about two weeks ago. Our rankings have not recovered, and the subdomains are still indexed per Webmaster Tools. Yesterday we submitted a Reconsideration Request. Will that help? Is there any other way to speed up the process of lifting the penalty? This is the site: http://goo.gl/3DCbl Thank you!

Strategy for recovering from Penguin
I have a web site that has been hit hard by the penguin update. I believe that main cause our problem has been links from low quality blogs and article sites with overly optimized keyword anchor text. Some questions I have are: I have noticed that we still have good ranking on long tail search terms on pages that did not have unnatural links. This leads me to believe that the penalty is URL specific, i.e. only URL with unnatural linking patterns have been penalized. Is that correct? Are URLs that have been penalized permanently tainted to the point that it is not worth adding content to them and continuing to get quality links to them? Should new contact go on new pages that have no history thus no penalty, or is the age of a previously highly ranked page still of great benefit in ranking? Is it likely that the penalty will go away over time if there are no more unnatural links coming in?

How do I clean up this 301 disaster?
I launched my site, InternetCE.com, and blog, www.continuingeducationjournal.com, a few years ago. I then learned I should probably merge the content, and foolishly created a subdomain, http://blog.internetce.com, and 301 redirected the blog to it. As an aside, my site is on a microsoft server, thus cannot host my wordpress blog on it. After a bit more study, I realized that my blog wasn't helping me nearly as much as it could be, so I 301'd it again to http://internetce.com/blog. In just becoming a pro member (long overdue) I realize that my entire site needs to be 301'd to merge non-www and www versions. I read somewhere that mr. cutts says not to 301 more than twice for fear of mistakenly being construed as something a bit to spammy. So, here I sit..not sure what to do. Does anyone have any advice on how to most efficiently correct this spaghetti bowl? Many thanks!
