Is it safe to 301 redirect old domain to new domain after a manual unnatural links penalty?
- 
					
					
					
					
 I have recently taken on a client that has been manually penalised for spammy link building by two previous SEOs. Having just read this excellent discussion, http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience I am weighing up the odds of whether it's better to cut losses and recommend moving domains. I had thought under these circumstances it was important not to 301 the old domain to the new domain but the author (Lewis Sellers) comments on 3/4/13 that he is aware of forwards having been implemented without transferring the penalty to the new domain. http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience#jtc216689 Is it safe to 301? What's the latest thinking?

 Thanks Karl.

 Thanks Francis, that example is useful.

 Ok, you'll probably be able to get the good links for your new domain then. Good luck with it all.

 My skepticism is based on what I have tested myself by redirecting a single page with too many spammy links (I would say, an infected page) to a new page tanked the traffic of the website. If you scale that, redirecting a penalised old domain to a new domain may give you the same bad result. Simple logic on my part. I would rather work on reviving that established same old domain. Keep going. Do what you are supposed to do - clean it, brand build it further, etc.

 Hi Carson, Thanks for your considered reply. I was very interested to hear your opinion about unnatural links warnings via GWT and whether they can be necessarily interpreted as manual penalties. As usual there are conflicting opinions and the particular wording in the warning I saw is different from the wording I have seen quoted in other examples on the web. It has a feel of being slightly more tailored ... although algorithms can do tailoring! It seems logical that Google would use an algorithmic approach wherever possible in the interests of economy and consistency but there have to be sanity checks by real people so maybe GWT emails can be triggered by algorithm or human override. The first sentence in both your "manual penalties" and also your "refreshing adjustments" suggest to me that it might not be possible to outmanoeuvre penalties by side-stepping (domain switching). Maybe there's also an argument here that what's best for the user should be what's best for SEO? What's best for the user must surely be not to confuse them or change domains so maybe that's the best approach also from an SEO POV. Oh boy. I love SEO but I think I'll do some gardening tomorrow.

 Hi Karl, Thanks. The situation is I reckon > 90% low quality or spammy links. I estimate I might be able to get between 10% and 30% deleted with several days work but which still produces no certainty of a successful re-consideration request. There are only a handful of good links which I know I could get re-coded to a new domain. This is a small business so flogging a dead horse is precious money down the drain . The domain is businessnamemainkeyword.com and I could host on businessname-mainkeyword.com i.e. only difference is the dash.

 Hi Scott, Thanks for your answer. Undoubtedly the safest decision is to take no risk at all i.e. use no redirects. That might not be the decision with the most profitable expected outcome. What if you knew, with hindsight, that you could have used redirects with only a 2% probability of a minor adverse impact on the new domain? That could have been a big opportunity lost by taking the safest option.. Again, I'm trying to get away from hunches and better understand the size and nature of the risks (probably by reference to empirical data i.e. specific cases) to give the best chance of making the best decision.

 Hi Francis, Thanks for your answer. From what you say, you have seen cases where redirects have been fine but you're skeptical which is a slightly mixed message. I am aware that there might be a risk of 'infecting' the new domain. I'm just trying to get some kind of handle on the level of that risk (if that is possible). Would you say: 1. Don't touch a 301 with a barge pole under any circumstances or 2. You should be OK under 'these circumstances' or 3. It's pot luck or 4. No need to worry about the consequences of 301s because Google will give you a fresh start. They know your motive for ditching the old domain and will filter the bad links from impacting the new domain, recognising you're a business that's been established for 1,000 years (from your business name, address, telephone number, company number etc.). Yeah, I know that last bit is probably my idealism getting the better of me. How to quantify the risk to make the best decision?

 Hi Ewan, This is a question that probably deserves a blog post at some point, along with a number of related questions about link-based penalties. I've been gathering info for some time, and have seem many instances of redirecting sites that have been penalized. I wish I could collect data on penalized sites more scientifically, but we work with what's available. Manual Penalties Manual penalties appear to carry through to new domains almost instantly when redirected to pages housing the same content. Google appears to use a number of signals to make sure that the redirect is to the same site and not to a competitor. Some Googlers have claimed that if you received an "unnatural link" warning in WMT, it's manual. I'm not entirely convinced of this, but it's now harder than ever to differentiate between manual link-based penalties and Penguin algorithmic adjustment. That brings us to... Refreshing Adjustments (Penalties) Panda, Penguin, and a few other updates are a little different. We've seen instances where a user makes a big change (a complete redesign for Panda, or redirecting the entire site); the trend seems to be a brief recovery followed by a drop once the algorithm refreshes. The obvious up-side here is that if you were going to recover from the penalty anyway, you may start to recover a bit sooner and don't have to wait for the next refresh. The downside is that it's a lot of work to do correctly, and it might be a very short-lived change. -- Generally, I'd say it's best to clean up the site and keep going on the same domain. If you have a lot of bad links pointing to a specific page, you may want to 410 that page and start a new one, then mention this in your reconsideration request. Otherwise, it's the old process of removal (keeping notes) and using disavow if reconsideration and clean up prove insufficient.

 The best thing would be to clean up the bad links, file a reconsideration request and then 301 the old domain to the new one...that is if you have some good links to the old domain. If you only have spammy links then starting afresh would probably be easier. 
- 
					
					
					
					
 We were in a similar situation and opted not top take the chance. We started from scratch and did not 301. Better safe than sorry. 
- 
					
					
					
					
 I have seen a certain case I analysed who did 301 redirects. They were fine but I am still skeptical doing such move. Personally, to 301 redirect a penalised site to a new domain may mean acquiring the spammy links from the old domain. I will not recommend it. If you think the old domain is no longer worth reviving then simply start a new website. This is a matter of calculating your resource spend vs benefits.

		Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
 We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this. Blog subdomain URL is https://blog.example.com/ and destination sub-directory URL is https://www.example.com/blog/ Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website. Following is our Technical Setup Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/ Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop. Change all absolute URLs to relative URLs on blog Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap. SEO Risk Evaluation We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are. Keeping this in mind, I am evaluating SEO Risks factors Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain? Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap? Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property? Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO? Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92% Intermediate & Advanced SEO | | joshibhargav_200

		Is domain authority lost if you create a 301 redirect but mark it as noindex, nofollow?
 Hi everyone, Our company sells products in various divisions. While we've been selling Product A and Product B under our original brand, we've recently created a new division with a new domain to focus on a Product B. The new domain has virtually no domain authority (3) while the original domain has some (37). We want customers to arrive on the new domain when they search for key search terms related to Product B instead of the pages that previously existed on our main website. If we create 301 redirects for the pages and content on the main site and add noindex, nofollow tags, will we lose the domain authority that we have from our original domain because the pages now have the noindex, nofollow tags? I read a few blog posts from Moz that said there isn't any domain authority lost with 301 redirects but I'm not sure if that is true if the pages are noindex, nonofollow. Do you follow? 🙂 Apologies for the lengthy post. Love this community and the great Moz team. Thanks, Joe Intermediate & Advanced SEO | | jgoehring-troy0

		Is there any benefit to changing 303 redirects to 301?
 A year ago I moved my marketplace website from http to https. I implemented some design changes at the same time, and saw a huge drop in traffic that we have not recovered from. I've been searching for reasons for the organic traffic decline and have noticed that the redirects from http to https URLs are 303 redirects. There's little information available about 303 redirects but most articles say they don't pass link juice. Is it worth changing them to 301 redirects now? Are there risks in making such a change a year later, and is it likely to have any benefits for rankings? Intermediate & Advanced SEO | | MAdeit0

		301 Redirect - Rank Recovery Examples?
 Hi All, I recently did a 301 redirect. Page to Page and the notified google via its console. Its been 6 days since. The home page and one other high traffic page swopped out with the new domain on google search index with 3-4 drops in ranking for each. The rest of the sites pages have been indexed but still reflect the old domain when searched. Recently today my home page dropped even further to the second page of google index for the specific keyword. Can you share similar experiences and how long it took you to recover rank fully? and how long for all pages to swop out on google search's index?

		How to avoid Google penalties being inherited when moving on with a new domain?
 Looking for SEOs who have experience with resetting projects by migrating on to a new domain to shed either a manual or algorithmic penalty. My questions are: For algorithmic penalties, what is the best migration strategy to avoid inheriting any kind of baggage? 301, 302, establish no connection between the two sites? For manual penalties, what is the best migration strategy to avoid inheriting any kind of baggage? 301, 302, establish no connection between the two sites? Any other input on these kind of reset projects is appreciated. Intermediate & Advanced SEO | | spanish_socapro0

		What are the effects of having Multiple Redirects for pages under the same domain
 Dear Mozers, First of all let me wish you all a Very Happy, Prosperous, Healthy, Joyous & Successful New Year ! I'm trying to analyze one of the website's Web Hosting UK Com Ltd. and during this process I've had this question running through my mind. This project has been live since the year 2003 and since then there have be changes made to the website (obviously). There have also been new pages been added, the same way some new pages have even been over-written with changes in the url structures too. Now, coming back to the question, if I've have a particular url structure in the past when the site was debuted and until date the structure has been changes thrice (for example) with a 301 redirect to every back dated structure, WOULD it impact the sites performance SEOwise ? And let's say that there's hundreds of such redirections under the same domain, don't you think that after a period of time we should remove the past pages/urls from the server ? That'd certainly increase the 404 (page not found) errors, but that can be taken care of. How sensible would it be to keep redirecting the bots from one url to the other when they only visit a site for a short stipulated time? To make it simple let me explain it with a real life scenario. Say if I was staying a place A then switched to a different location in another county say B and then to C and so on, and finally got settled at a place G. When I move from one place to another, I place a note of the next destination I'm moving to so that any courier/mail etc. can be delivered to my current whereabouts. In such a case there's a less chance that the courier would travel all the destinations to deliver the package. Similarly, when a bot visits a domain and it finds multiple redirects, don't you think that it'd loose the efficiency in crawling the site? Ofcourse, imo. the redirects are important, BUT it should be there (in htaccess) for only a period of say 3-6 months. Once the search engine bots know about the latest pages, the past pages/redirects should be removed. What are your opinions about this ? Intermediate & Advanced SEO | | eukmark0

		Geoip redirection, 301 or 302?
 Hello all Let me first try to explain what our company does and what it is trying to achieve. Our company has an online store, sells products for 3 different countries, and two languages for each country. Currently we have one site, which is open to all countries, what we are trying to achieve is make 3 different stores for these 3 different countries, so we can have a better control over the prices in each country. We are going to use Geoip to redirect the user to the local store in his country. The suggested new structure is to add sub-folders as following: www.example.com/ca-en Intermediate & Advanced SEO | | ajarad
 www.example.com/ca-fr
 www.example.com/us-en
 ... If a visitor is located outside these 3 countries, then she'll be redirected to the root directory www.example.com/en We can't offer to expand our SEO team to optimize new pages for the local market, it's not the priority for now, the main objective now is to be able to control the prices for different market. so to eliminate the duplicate issue, we'll use canonical tags. Now knowing our objective from the new URL structure, I have two questions: 1- which redirect should we use? 301, 302?
 If we choose 301, then which version of the site will get the link juice? (i.e, /ca-en or /us-en?)
 if we choose 302, then will the link juice remain in the original links? is it healthy to use 302 for long term redirections? 2- Knowing that Google bots comes from US-IP, does that mean that the other versions of the site won't be crawled (i.e, www.example.com/ca-fr), this is especially important for us as we are using AdWords, and unindexed pages will effect our quality score badly. I'd like to know if you have other account structure in your mind that would be better than this proposed structure. Your help is highly highly appreciated.
 Thanks in advance.0

		How To 301 Redirect .html pages
 I need to redirect a page/URL that is purely .html to a new location. I don't know how to do this. All the redirects I can find are for server side code pages .php/.aspx etc. From my understanding I can't put a server side redirect in a .html file. I am hosting on a microsoft server, however the new page I am redirecting to is .php. I am running some WordPress (.php) files on the server. I need to make it redirect before the old page loads so visitors don't start reading something that is about to get redirected Can someone please help me?
