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.

I am temporarily moving a site to a new domain. Which redirect is best?
A client is having their site redeveloped on a new platform in sections and are moving the sections that are on the new platform to a temporary subdomain until the entire site is migrated. This is happening over the course of 2-3 months. During this time, is it best for the site to use 302 temporary redirects during this time (URL path not changing), or is it best to 301 to the temp. domain, then 301 back to the original once the new platform is completely migrated? Thanks!

HTTPS Login on HTTP Site | 301 or 302 Redirect?
I've searched the forum on this and online and can't seem to find a definitive answer. Some e-commerce sites that are http use a 302 redirect to the https login while other sites use a 301 redirect. I know 302 is generally not recommended but in this case it may make sense. Can anyone advise on the correct practice?

Penalty after 301 redirect?
We run a training center. We had 1 main website and 2 dedicated websites to certain themes. The 2 dedicated websites are older and the main website is about 6 months old. The 2 dedicated websites had a top 5 ranking for their most important keywords. 2 weeks ago we imported all the content from the dedicated websites into the main website. Then immediately after we did a perfect 301 redirect of these websites to the main website. 2 SEO companies checked it for us and so I'm very sure this is done right. Google immediately caught this up and gave the main website a boost. We where in the top 10 for many important keywords for 1 week. The next week all our rankings dropped. We only have a top 50 ranking for 10 keywords. Before it was 75 keywords in the top 20. Do you know what could have caused this? Any suggestion, thought, ... is welcome!

How should I manage duplicate content caused by a guided navigation for my e-commerce site?
I am working with a company which uses Endeca to power the guided navigation for our e-commerce site. I am concerned that the duplicate content generated by having the same products served under numerous refinement levels is damaging the sites ability to rank well, and was hoping the Moz community could help me understand how much of an impact this type of duplicate content could be having. I also would love to know if there are any best practices for how to manage this type of navigation. Should I nofollow all of the URLs which have more than 1 refinement used on a category, or should I allow the search engines to go deeper than that to preserve the long tail? Any help would be appreciated. Thank you.

3 Wordpress sites 1 Tumblr site coming under 1domain(4subdomains) WPMU: Proper Redirect?
Hey Guys, witnessSF.org (WP), witnessLA.org(Tumblr), witnessTO.com(WP), witnessHK.com(WP), and witnessSEOUL.com(new site no redirects needed) are being moved over to sf.ourwitness.com, la.ourwitness.com and so forth. All under on large Wordpress MU instance. Some have hundreds of articles/links others a bit less. What is the best method to take, I understand there are easy redirects, and the complete fully manual one link at a time approach. Even the WP to WP the permalinks are changing from domain.com/date/post-name to domain.com/post-name? Here are some options: Just redirect all previous witinessla.org/* to la.ourwitness.org/ (automatic direct all pages to home page deal) (easiest not the best)2) Download Google Analytics top redirected domains about 50 urls have significant ranking and traffic (in LA's sample) and just redirect those to custom links. (most bang for the buck for the articles that rank manually set up to the correct place) 3) Best of the both worlds may be possible? Automated perhaps?I prefer working with .htaccess vs a redirect plugin for speed issues. Please advise. Thanks guys!

How To Detect Primary Site With Duplicate Domains?
I'm working with some backlink data, and I've run into different domains that host the same exact content on the same IP. They're not redirecting to each other, just looks like they're hosting the same content on differnet virtual hostnames. One example is: borealcanada.ca borealcanada.com borealcanada.org www.borealcanada.ca www.borealcanada.com www.borealcanada.org www.borealecanada.ca I'm trying to consolidate this data and choose which is the primary domain. In this example, it appears www.borealcanada.ca has a high number of indexed pages and also ranks first for "boreal canada". However, I'm trying to think of a metric I can use to definitively/systematically handle this (using SEO Tools or something like it). Anyone have ideas on which metric might help me determine this for a large number of sites?

Adding a huge new product range to eCommerce site and worried about Duplicate Content
Hey all, We currently run a large eCommerce site that has around 5000 pages of content and ranks quite strongly for a lot of key search terms. We have just recently finalised a business agreement to incorporate a new product line that compliments our existing catalogue, but I am concerned about dumping this huge amount of content (that is sourced via an API) onto our site and the effect it might have dragging us down for our existing type of product. In regards to the best way to handle it, we are looking at a few ideas and wondered what SEOMoz thought was the best. Some approaches we are tossing around include: making each page point to the original API the data comes from as the canonical source (not ideal as I don't want to pass link juice from our site to theirs) adding "noindex" to all the new pages so Google simply ignores them and hoping we get side sales onto our existing product instead of trying to rank as the new range is highly competitive (again not ideal as we would like to get whatever organic traffic we can) manually rewriting each and every new product page's descriptions, tags etc. (a huge undertaking in terms of working hours given it will be around 4,400 new items added to our catalogue). Currently the industry standard seems to just be to pull the text from the API and leave it, but doing exact text searches shows that there are literally hundreds of other sites using the exact same duplicate content... I would like to persuade higher management to invest the time into rewriting each individual page but it would be a huge task and be difficult to maintain as changes continually happen. Sorry for the wordy post but this is a big decision that potentially has drastic effects on our business as the vast majority of it is conducted online. Thanks in advance for any helpful replies!
