How does Google treat chained 301 redirects?
-
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?
-
From other blog posts and my also from own experience, you are losing approx 15% linkjuice for each 301 hop. Too many hops and Google will give up ...Matt Cutts recommended not having more than 2 or at the most 3 redirect hops for googebot to crawl.

Hi Bull, actually I don't recommend you to make a 100% accurate math on how much juice is lost, what you have to maintain clear is that this will make you lose value.
So, if you really need to make those redirects, try to reduce them to only one step, but, for ease of management if you REALLY need to create two steps redirects consider that you'll be losing the same value you'll be losing from one page linking to another and to other one (further reading here).
For page rank (juice) purposes 301 are treathed as links. However what I recommend you is after having put in place the generic redirect rules, identify your best traffic delivering pages and create an ad-hoc 301 for those ones, so you'll be sure those urls will receive least impact in that sense.

301 redirecting a site that currently links to the target site
I have a personal blog that has a good amount of back links pointing at it from high quality relevant authoritative sites in my niche. I also run a company in the same niche. I link to a page on the company site from the personal blog article that has bunch of relevant links pointing at it (as it's highly relevant to the content on the personal blog). Overview: Relevant personal blog post has a bunch of relevant external links pointing at it (completely organic). Relevant personal blog post then links (externally) to relevant company site page and is helping that page rank. Question: If I do the work to 301 the personal blog to the company site, and then link internally from the blog page to the other relevant company page, will this kill that back link or will the internal link help as much as the current external link does currently? **For clarity: ** External sites => External blog => External link to company page VS External sites => External blog 301 => Blog page (now on company blog) => Internal link to target page I would love to hear from anyone that has performed this in the past 🙂

What is Google supposed to return when you submit an image URL into Fetch as Google? Is a few lines of readable text followed by lots of unreadable text normal?
I am seeing something like this (Is this normal?): HTTP/1.1 200 OK

To redirect or not to redirect, that is the question
I work for a software company that is redeveloping the website (same domain.) We have tons of content in the form of articles and documents for support, how to use the product better, case studies, and blog posts. I've downloaded a landing page report and many of these have low impressions and little or no clicks (some ranked high other very low.) Should I redirect all this content to the new site where some of it won't exist or forget about it because of the lack of juice? Is there a rule-of-thumb threshold for redirecting for content?

Should we 301 redirect old events pages on a website?
We have a client that has an events category section that is filled to the brim with past events webpages. Another issue is that these old events webpages all contain duplicate meta description tags, so we are concerned that Google might be penalizing our client's website for this issue. Our client does not want to create specialized meta description tags for these old events pages. Would it be a good idea to 301 redirect these old events landing pages to the main events category page to pass off link equity & remove the duplicate meta description tag issue? This seems drastic (we even noticed that searchmarketingexpo.com is keeping their old events pages). However it seems like these old events webpages offer little value to our website visitors. Any feedback would be much appreciated.

301 Redirecting from Static to Dynamic URLs. I think we messed up
I'm looking for some guidance on an issue I believe we created for ourselves and if we undo what we did. We recently added attributed search to our sites. This of course created a bunch of dynamically generated URLS. For various reasons, it was decided to take some of our existing static URLs and 301 redirect them to their dyanamic counterpart. Ex .../Empire-Paintball-Masks-0Y.aspx now redirects to .../Paintball-Masks-And-Goggles-0Y.aspx?Manufacturer=Empire Many of these stat URLS had top 3 rankings for their associated keywords. Now, we don't rank for anything. I realize that 301 redirecting is the way to go...if you NEED to. My guess is our drop in keyword ranking is directly tied to what we did. I'm looking for an solid argument to be made to my boss as to why we should not have done this and that it, more than likely has resulted in dropped keyword rankings and organic traffic. I welcome any input. Also, if we decided to revert back (remove all 301 redirects and de-index all dynamic URLS), what is the likely hood we can recapture some of this lost organic traffic? Can I disallow indexing in a robot.txt file to remove, say anything with a '?' in the URL? Would the above URL example (which was ranking in the top 3 in SERPs), have a good chance of finding its way back? thanks

301 Redirection problems
A couple of days ago we did a restructure of our e-commerce site (wordpress + woocomerce) where some product categories needed to change names. I used Yoast SEO plugin to do 301 redirects in the .htaccess file.Today I noticed that we had two hits in the SERP on the phrase "dildos med vibrator". See the attached screenshot (first two results).One goes to http://www.oliverocheva.se/kategori/sexleksaker/dildos/dildos-med-vibrator/ which is the right URL. One goes to http://www.oliverocheva.se/kategori/sexleksaker/dildosdildos-med-vibrator-dildos-for-honom/ which is a corrupt URL that has never been in use. The old one we did a redirect from was /kategori/for-honom/dildos-for-honom/dildos-med-vibrator-dildos-for-honom/The command in the .htaccess file was: Redirect 301 /kategori/for-honom/dildos-for-honom/dildos-med-vibrator-dildos-for-honom/ http://www.oliverocheva.se/kategori/sexleksaker/dildos/dildos-med-vibratorWhat has happened here? Why does the 301 create entirely new URL:s in the SERP?Tz0TULT.png

Google penalized site--307/302 redirect to new site-- Via intermediate link—New Site Ranking Gone..?
Hi, I have a site that google had placed a manual link penalty on, let’s call this our
Intermediate & Advanced SEO | | Robdob2013
company site. We tried and tried to get the penalty removed, and finally gave up and purchased another name. It was our understanding that we could safely use either a 302 or 307 temporary redirect in order to redirect people from our old domain to our new one.. We put this into place several months and everything seemed to be going along well. Several days ago I noticed that our root domain name had dropped for our selected keyword from position 9 to position 65. Upon looking into our GWT under “Links to Your site” , I have found many, many, many links which were pointed to our old google penalized domain name to our new root domain name each of this links had a sub heading “Via this intermediate link -> Our Old Domain Google Penalized Domain Name” In light of all of this going on, I have removed the 307/302 redirect, have brought the
old penalized site back which now consists of a basic “we’ve moved page” which is linked to our new site using a rel=’nofollow’ I am hoping that -1- Our new domain has probably not received a manual penalty and is most likely now
received some sort of algorithmic penalty, and that as these “intermediate links” will soon disappear because I’m no longer doing the 302/307 from the old sight to the new. Do you think this is the case now or that I now have a new manual penalty place on the new
domain name.. I would very much appreciate any comments and/or suggestions as to what I should or can do to get this fixed. I need to still keep the old domain name as this address has already been printed on business cards many, many years ago.. Also on a side note some of the sub pages of the new root domain are still ranking very
well, it’s only the root domain that is now racking awfully.. Thanks,0 -
How to 301 redirect ASP.net URLS
I have a situation where a site that was ASP.net has been replaced with a WordPress site. I've performed a Open Site Explorer analysis and found that most of the old pages, ie www.i3bus.com/ProductCategorySummary.aspx?ProductCategoryId=63 are returning a HTTP Status = NO DATA ... when followed ends up at the 404 catch-all page. Can I code the standard 301 Redirects in the .htaccess file for these ASP URLs? If not, I'm open to suggestions.... Thanks Bill
