Accidentally blocked Googlebot for 14 days
-
Today after I noticed a huge drop in organic traffic to inner pages of my sites, I looked into the code and realized a bug in last commit cause the server to showing captcha pages to all Googlebot requests from Apr 24.
My site has more than 4,000,000 in the index. Before last code change, Googlebot are exempt from being shown the captcha requests so each inner pages are crawled and indexed perfectly with no problem.
The bug broke the whitelisting mechanism and treat requests from Google's ip addresses the same as regular users. It leads to the captcha page being crawled when Googlebot visits thousands of my site's inner pages. This makes Google thinks all my inner pages are identical to each other. Google remove all the inner pages from SERP starting from May 5th before when many of those inner pages have good rankings.
I formerly thought this was a manual or algorithm penalty but
1. I did not receive a warning message in GWT
2. The ranking for main url is good.I tried with "Fetch as Google" in GWT and realize all Googlebot saw in the past 14 days are the same captcha page for all my inner pages.
Now, I have fixed the bug and updated the production site. I just wanted to ask:
1. How long will it take for Google to remove the "duplicated content" flag on my inner pages and show them in SERP again? From my experience, Googlebot revisits urls quite often. But once a url is flagged as "contains similar content", it could be difficult to recover, is it correct?
2. Besides waiting for Google to update its index, what else can I do right now?
Thanks in advance for your answers.

Thanks for the info. My site has current crawl rate at 350,00 pages per day so will take 10-20 days to crawl the entire sites.
Most of organic traffic comes to 10,000 urls while others are pagination urls etc. Now all the traffic 1st inner page of each term disappeared in the results of inurl: command.

One of my competitors made this type of error and we figured it out right away when their site dropped from the SERPs. It took them a couple weeks to figure it out and make the change. We were hoping that they never figured it out so we could rake in lots of dough. When they fixed it they were back in the SERPs at full strength within a couple of days.... . but they had 40 indexed pages instead of 4,000,000.
I think you will recover well, but might take a while if you don't have a lot of deep links.
Good luck.

Pretty much all you can do is wait for Google to recrawl your entire site. You can try re-submitting your site in Webmaster Tools (Health -> Fetch As Google). Getting links from other sites will help speed up the crawling as well. Links from social sites like Twitter/Google+ can help with crawling also.

Does CAPTCHA Block Crawlbots?
Hi, My client's website occasionally asks users to verify their usage by checking the CAPTCHA box. This is only done once per session and is done randomly. Does having CAPTCHA before content loads block crawl bots from properly indexing pages? Does it have any negative impact on SEO? Thanks, Kevin

Google Webmaster Tools is saying "Sitemap contains urls which are blocked by robots.txt" after Https move...
Hi Everyone, I really don't see anything wrong with our robots.txt file after our https move that just happened, but Google says all URLs are blocked. The only change I know we need to make is changing the sitemap url to https. Anything you all see wrong with this robots.txt file? robots.txt This file is to prevent the crawling and indexing of certain parts of your site by web crawlers and spiders run by sites like Yahoo! and Google. By telling these "robots" where not to go on your site, you save bandwidth and server resources. This file will be ignored unless it is at the root of your host: Used: http://example.com/robots.txt Ignored: http://example.com/site/robots.txt For more information about the robots.txt standard, see: http://www.robotstxt.org/wc/robots.html For syntax checking, see: http://www.sxw.org.uk/computing/robots/check.html Website Sitemap Sitemap: http://www.bestpricenutrition.com/sitemap.xml Crawlers Setup User-agent: * Allowable Index Allow: /*?p=

Googlebots and cache
Our site checks whether visitors are resident in the same country or live abroad. If it recognises that the visitor comes from abroad, the content is made more appropriate for them. Basically, instead of encouraging the visitor to come and visit a showroom, it tells them that we export worldwide. It does this by IP checking. So far so good! But I noticed that if I look at cached pages in Google's results, that the cached pages are all export pages. I've also used Google Webmaster Tools (Search Console) and rendered pages as Google - and they also render export pages. Does anybody have a solution to this?

Recovering from Blocked Pages Debaucle
Hi, per this thread: http://www.seomoz.org/q/800-000-pages-blocked-by-robots We had a huge number of pages blocked by robots.txt by some dynamic file that must have integrated with our CMS somehow. In just a few weeks hundreds of thousands of pages were "blocked." This number is now going down, but instead of by the hundreds of thousands, it is going down by the hundreds and very sloooooowwwwllly. So, we really need to speed up this process. We have our sitemap we will re-submit, but I have a few questions related to it: Previously the sitemap had the <lastmod>tag set to the original date of the page. So, all of these pages have been changed since then. Any harm in doing a mass change of the <lastmod>field? It would be an accurate reflection, but I don't want it to be caught by some spam catcher. The easy thing to do would be to just set that date to now, but then they would all have the same date. Any other tips on how to get these pages "unblocked" faster? Thanks! Craig</lastmod></lastmod>

Site blocked by robots.txt and 301 redirected still in SERPs
I have a vanity URL domain that 301 redirects to my main site. That domain does have a robots.txt to disallow the entire site as well. However, for a branded enough search that vanity domain still shows up in SERPs and has the new Google message of: A description for this result is not available because of this site's robots.txt I get why the message is there - that's not my , my question is shouldn't a 301 redirect trump this domain showing in SERPs, ever? Client isn't happy about it showing at all. How can I get the vanity domain out of the SERPs? THANKS in advance!

Google: site gone from SERPs, back in 1 day, then gone again?
Last December we fumbled our 404 error page with a misconfigured server and broken links on the page. Needless to say, our site dropped into an abyss - for 4 months. Yesterday we appeared again in our regular placement (actually stronger placement). Our site has been around since 09-Jan-1999 and has been a highly regarded site with good link structure and solid content for engineers. Then today we're gone again. Yesterday morning we had 125,000 pages indexed with Google which grew to 187,000 by late afternoon. Then this morning we're nowhere to be found and only 21,800 pages are now indexed. We've been working with Bruce Clay Inc through an SEO site audit doing several updates to improve through good seo practices. We haven't made any changes to the site since last Friday, April 13th (maybe the unlucky number has something to do with it....) Any ideas, insight, suggestions???? Thanks!

Does Google take user site blockings from Chrome as a spam signal?
When you perform a search in Chrome, click through to a result, then hit "back", you get a nice little option to "Block all example.com results" listed next to the result from which you backed out. I am assuming Google collects this information from Chrome users whose settings allow them to? I am assuming this is a spam signal (in aggregate)? Anyone know? Thanks!
