Will using 301 redirects to reduce duplicate content on a massive scale within a domain hurt the site?
-
We have a site that is suffering a duplicate content problem. To help resolve this we intend to reduce the amount of landing pages within the site. There are a HUGE amount of pages.
We have identified the potential to reduce the pages by half at first by combing the top level directories, as we believe they are semantically similar enough that they no longer warrant being seperated.
For instance: Mobile Phones & Mobile Tablets (Its not mobile devices).We want to remove this directory path and 301 these pages to the others, then rewrite the content to include both phones and tablets on the same landing page.
Question: Would a massive amount of 301's (over 100,000) cause any harm to the general health of the website? Would it affect the authority? We are also considering just severing them from the site, leaving them indexed but not crawlable from the site, to try and maintain a smooth transition. We dont want traffic to tank.
Has anyone performed anything similar? Id be interested to hear all opinions. Thanks!

Yes that's correct
The pages will be found just as quick thought there new links as they would have been though their old links with 301's
-
Thanks Alan.I Take it by this you mean we should only 301 redirect pages with valuable links and forget the rest?
The pages dont have any links worth worrying about as its the "weaker" half of the site. We're more concerned over the site restructure and the affecting the general health of the site by losing so many pages at once.

I would look at your links coming into those pages, and 301 the links only, I doubt all 100,000 pages have links.
A 301 only redirects link juice, so if no external links no problem, of cause you need to change your internal links. You should never 301 internal as 301's leak link juice, you should fix your internal links.

Website can't break into Google Top100 for main keywords, considering 301 Redirect to a new domain
A little background on our case. Our website, ex: http://ourwebsite.com was officially live in December 2015 but it wasn't On-Site optimized and we haven't done any Off-site SEO to it. In April we decided to do a small redesign and we did it an online development server. Unfortunately, the developers didn't disallow crawlers and the website got indexed while we were developing it on the development server. The development version that got indexed in Google was http://dev.web.com/ourwebsite We learned that it got indexed when we migrated the new redesigned website to the initial domain. When we did the migration we decided to add www and now it looks like: http://www.ourwebsite.com Meanwhile, we deleted the development version from the development server and submitted "Remove outdated content" from the development server's Search Console. This was back in early May. It took about 15-20 days for the development version to get de-indexed and around 30 days for the original website (http://www.ourwebsite.com) to get indexed. Since then we have started our SEO campaign with Press Releases, Outreach to bloggers for Guest and Sponsored Posts etc. The website currently has 55 Backlinks from 44 Referring domains (ahrefs: UR25, DR37) moz DA:6 PA:1 with various anchor text. We are tracking our main keywords and our brand keyword in the SERPs and for our brand keyword we are position #10 in Google, but for the rest of the main (money) keywords we are not in the Top 100 results in Google. It is very frustrating to see no movement in the rankings for the past couple of months and our bosses are demanding rankings and traffic. We are currently exploring the option of using another similar domain of ours and doing a complete 301 Redirect from the original http://www.ourwebsite.com to http://www.ournewebsite.com Does this sound like a good option to you? If we do the 301 Redirect, will the link-juice be passed from the backlinks that we already have from the referring domains to the new domain? Or because the site seems "stuck," would it not pass any power to the new domain? Also, please share any other suggestions that we might use to at least break into the Top 100 results in Google? Thanks.

Where/how do you set up 301 redirects when keeping the same domain and not preserving the filename?
Hi there, I'm just reaching to to ask for some help in understanding where 301 redirects should be set up on a website when keeping the same domain but not preserving the original filenames? Essentially what is happening is an old website is being completely overhauled and brought up to date from a technical and usability standpoint. While the SEO isn't great naturally many of the pages have been indexed by google over time. A few pages have decent statistics and I don't want to lose the juice from them, but they do still need a lot of improving. So my question is this, would all the redirection take place in the .htaccess file only in this case? From reading here on Moz I think this is the case, but I need to confirm that. I was reading this article which has thrown me slightly: https://moz.com/learn/seo/redirection but this seems more complex as the website was actually moving domains. Open to any insight and if you need further clarification or information let me know.

Multilingual Site and 301 redirection
Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

Need some expert help – My Client bought out competitor and now wants to completely duplicate the current site with the same stock & categories using the Competitor brand
I am the SEO consultant for a large online homewares store. This company currently ranks very well in Google. I can PM the domain name if anyone needs however i don't want to post it on this forum. The company has bought out a competitor and plan to use the same warehouse, same products, and same back-end system as the current site, so they want to completely duplicate the current website. Titles, meta descriptions, product descriptions will all be renamed/rewritten/reworded (however keep in mind there are not many ways to reword a 3 piece saucepan set) Pricing will mostly be the same (some difference though), images cannot be renamed, categories cannot be renamed... the structure of the site will be exactly the same... placement etc. (however will have different banners, logo etc.) I personally don't believe the new site will rank, because it will be too similar. Can someone please offer me a 2nd opinion... Thanks

Redirecting Existing Domains to My Main Site
Hi I have a main property related website featuring different countries around the world. I also have many different seperate country websites 20+. All keyword rich domains with a good 9 years+ domain age and PR3's with decent links and moz rankings and unique content. Many of the sites are very low Alexa rank now and receive little traffic. I don't have the time now to spend on each of the individual domains and am wanting to consolidate them and their PR juice to the corresponding country page of my main website. My question is - is it possible - will google see this as me trying to manipulate them and is my main site likely to suffer from any penalties or downgrading? Thanks for your input.
