Welcome to the Q&A Forum

Suppose the following scenarios after a 301 redirects from source URL to targent URL is removed.

1. If source URL raises a 404 error, will target URL retained the link juice previously passed from source URL?

2. If source URL starts to show different content than what is showing on target URL, will the previously passed link juice be credited back to the source URL?

If I 301 redirects all urls from

http://domain.com/folder/keyword

to

http://domain.com/folder/keyword.htm

Are new urls likely to keep most of link juicy from source url and maintain the rankings in SERP?

I did the following two chained 301 redirects (A->B->C)

Plural to Singular to New Domain

A. http://domain1.com/filenames

B. http://domain1.com/filename

C. http://domain2.com/filename

To new domain without www and then back to origining domain

A. http://www.domain1.com/filename

B. http://domain2.com/filename

C. http://domain1.com/fifilename

How much link juicy will be rediectetoto URL C in above two scenarios?

Thanks for your answer. If you looked into mafiashare's link report by ahrefs.com, you will not see any natural links. I am sure if they have made any white hat efforts, it's pretty much under Ahrefs's radar.

The sudden traffic surge of mafiashare.net is unnatural by any means. The most surprising is it has maintained its traffic for half year.

Obvious spammy sites with sudden traffic surge are likely to be filtered in 3 months.

It's widely known that links from theme sponsorshare do not work well as it was a few years ago. And footer links are kind of useless or even risky.

But take a look roofline link profile and traffic chart of mafiashare.net, you will find different worth more research.

1. Most back links to mafiashare.net are from crappy Wordpress themes with various anchor text and even embedded in mis-used "scroll to top" button.

2. OSE shows linking root domains in 1,000+, ahrefs shows ratio of sitewide links is not too high.

Does mafiashare.net survive but using above two tactics combined? It has been in alexa top 10,000 for nearly half year. Maybe keep black/gray hat in a small scale is good to avoid the radar while benefit the rankings?

Any thoughts are welcome. If you happened to know other websites being successful by sponsoring theme links, please share here.

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.

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.

Hi,

I have an old domain which accidentally was set as PENDINGDELETE by the registry. It's now not resolving to any ip address any more.

Actually I was relocating from the old domain to a new domain. Just one month before it become PENDINGDELETE, I have submitted a "Chang of Address" in Google Webmasters Tools as well as setup the web server to 301 redirect all urls on old domain to the new domain.

I have some sub-questions for this case:

1. What will happen to the effectiveness of the "Change of Address" in Google Webmasters Tool after old domain is dropped. As a domain is deleted, I have no way to maintain the verified ownership of the it in case Google asks me to reverify.

2. Suppose during last month before it's deleted, Googlebot had crawled 50% of urls on old domains, detected the 301 redirects and save them to its index. When Googlebot crawls those 50% urls again after the old domain is deleted, as those urls are not resolving to any web server, will Googlebot retain the last 301 redirects or drop the 301 redirects as well?

3. After a domain is deleted, how soon will Google purge urls on old domain from its index?

Thank you.

Best regards
