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.

Our new site will be using static site generator which is supposed to be better for SEO?
Hi folks, Our dev team is planning on building our new marketing webpages on SSG or Static Site Generator(we are stepping away from SSR). Based on my research this is something that can help our SEO in particular for site speed (our site has a poor score).

Will we be penalised for duplicate content on a sub-domain?
Hi there, I run a WordPress blog and I use [community platform] Discourse for commenting. When we publish a post to Wordpress, a duplicate of that post is pushed to a topic on Discourse, which is on a sub-domain. Eg: The original post and the duplicated post. Will we be penalised for duplicating our own content on a subdomain? If so, other than using an excerpt, what are our options? Thanks!

If you do 302 redirect then change to 301 redirect do you lose all link juice?
Hello everyone, I was wondering if you could help me with understanding the following story: A website has been moved from its HTTP version to a HTTPS version. The SEO manager has advised developers that they needed to do 301 redirects. However, in the end, 302 redirects have been put in place instead. Now, 301s should be put in place ASAP. The million dollar question is: has the website lost all of its link juice already given the nature of the redirects? Also, does it depend on whether Google has indexed the new 302 pages or does it depend on something else? Many thanks!

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

What's the best way to manage content that is shared on two sites and keep both sites in search results?
I manage two sites that share some content. Currently we do not use a cross-domain canonical URL and allow both sites to be fully indexed. For business reasons, we want both sites to appear in results and need both to accumulate PR and other SEO/Social metrics. How can I manage the threat of duplicate content and still make sure business needs are met?

Duplicate Content On A Subdomain
Hi, We have a client who is currently close to completing a site specifically aimed at the UK market (they're doing this in-house so we've had no say in how it will work). The site will almost be a duplicate (in terms of content, targeted keywords etc.) of a section of the main site (that sits on the root domain) - the main site is targeted toward the US. The only difference will be certain spellings and currency type. If this new UK site were to sit on a sub domain of the main site, which is a .com, will this cause duplicate content issues? I know that there wouldn't be an issue if the new site were to be on a separate .co.uk domain (according to Matt Cutts), but it looks like the client wants it to be on a sub domain. Any help/advice would be greatly appreciated.

Does having many 302 redirects on a site hurt rankings?
I am working with an affiliate website which has many product listings but the "Buy Now" button on each product listing is an external link (affiliate link) to the appropriate product page on the actual website where the product can be bought. Each of these external links passes through an internal redirect, which is implemented as a 302. Consequently, when SEOmoz crawls that site, it gives me a warning that there are hundreds of 302 redirects on the site. Do you think this will hurt the site's potential to rank? Should I remove the redirects and leave them as direct links to the external site?
