Does any one have experience with SEO and .NET using 301 redirects?
-
A while ago I altered some of the URL's of my website. Google now thinks that I have two duplicate pages (duplicate content), I have asked my third party web developers (Who use .NET and a custom built CMS system) to simply 301 redirect the old URL to the other.
However, my web developers say the following:
"Solving the problems by 301 permanent re directs are out of the question as this would create infinite loops. Likely to bring down our server."
They also wont do a canonical, as they say there is only one page (but two URLs)
Firstly, has any one heard of this before and do they think this is true?
Also, does anyone have an alternative method of getting rid of the old URL?
Any thoughts would be much appreciated.

Hi Thomas
At the risk of being blunt, they're having you on.
Having used the .net system and a lot of CMS', while I know the inifinite loop problem does exist, it is not a "stock" problem with .net or any CMS I've encountered. If the 301s are returning a loop, it;s likely the dev team's implementation of the CMS and not the .net framework to blame. From this point of view (which isn't the whole story of course), it's their job to solve it.
In addition, adding a canonical to one URL would help the problem. If only one page exists, adding a canonical tag to the one page is a strong directive to Google to index only that version of the URL. That means, eventually, Google would stop indexing the other URL flagging the duplicate content. So this would solve the issue.
That's presuming that the other URL that's creating duplicate content is a variant of the page, like a query string (www.domain.com/example and www.domain.com/example?query). If it was a completely different URL (www.domain.com/anotherexample) and it is showing the same content, but not redirecting, then there would be 2 pages in existence. Again, either a redirect or canonical will help, although you could also get the devs to add <noindex,nofollow>to the meta tag of the page.</noindex,nofollow>
If all else fails, you could use your robots.txt file to block any crawler from reaching the URL.
Here's a handy guide that helps explain all these options.
Hope this helps.

Reusing an already 301 redirected URL for a very important keyword
I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

Heroku, Subdomains, redirecting to different servers & SEO
Hi all, I've got a big question. I'm helping out with digital marketing at a non-profit that I volunteer with. We're working on developing an on site blog for our site, because we've realized we need that middle of the funnel content. Our issue has been taking up much of the developers' time & we're really working out the kinks with the system, so I'm trying to alleviate that with a light blog solution. We're considering installing a wordpress site on a separate server from the main site & sending traffic over to that. The primary questions: Do we negatively impact our main site by having a link to a different domain in the topnav? Do we positively impact the main site by developing SEO content on a redirected&masked URL? What are the ramifications of redirecting a subdomain to another server? Would we be better off using something like Ghost? A good example would be: Visit theMainDomain

1000 Pages on old website. What to do with the 301 redirects for this domain?
Hi Moz Community, I have a 301 redirect question... I just acquired an old domain: Totally in my niche Domain is 14 years old Website exists of 1000 pages Great amount of backlinks Website is offline since about 2 weeks Will place a new website online asap with new url structure For the 50 best scoring pages I wrote a new, but fully comparable/related article. I will put a 301 redirect from those old to the new pages. My question: What to do with the 950 other url's? Should I put a 301 redirect to the homepage? Should I forward those pages to the 404 page? Should I divide the 950 url's with a 301 redirect to the 50 new ones? Another solution maybe? Any idea what would be the best solution so we can save as much Google juice as possible? Thanks in advance!

480,000 Redirects - Is this hurting my SEO? PLEASE HELP!
Hello everyone, I have over 480,000 internal rewrites in my Magento site. The reason I have so many is because I have over 1,500 products on my site and I update inventory every day via Bulk Import Extension. For the first few months I didn't realize that the URL was changing by a single digit every time I imported the .xml with new inventory counts. This of course created thousands and thousands of 404s. I figured out how to avoid the digit change and then I started redirecting the 404s via a Bulk Rewrite Extension. I managed to rewrite over over 50,000 404s but new ones still pop up every day and there is no end to them in sight. My traffic is terrible. Only about 40 organics daily. It's been like that for months. I can't get it off the ground and I think it's because of this excessive rewrite and 404 issue. My question is, does having so many internal rewrites and 404s hurt my SEO efforts? Would it be better just to start from scratch with a new site, new domain, new everything? Please help me. I'm going crazy with this. Thank you. Nico.

301 redirect and search engines
How long until 301 redirects get recognized by search engines? I noticed my link on Google isn't forwarding over to my new domain even after the 301 redirect. If I go to the site directly, the 301 redirect works. Anyone know how long it takes for search engines to pick it up? Thanks!

Should we 301 redirect our old domain to the new domain
We have a product that when started was under the domain appnowgo.com. We've since changed the name and the domain is now knackhq.com. The latter domain doesn't rank nearly as well as the former for many of the keywords we are targeting. For example... "online database builder" and "web app builder" are two of those keywords. Obviously having app in the domain is not a bad thing but it is our old name. The question is, should we 301 the appnowgo.com domain to knackhq.com? Or should we use that better rank and just link users to knackhq.com from the appnowgo.com site until we can increase our ranking for knackhq.com? We don't plan to update the content on appnowgo.com anymore and we obviously don't want to drop off rank if at all possible. Thanks! Eric

What factors matters the most when using a 301 permanent redirect?
Hi SEOmozzers, I have a client that has couple of duplicates but I am debating if i should just kill those pages or use 301 Permanent redirects. I know SEO moz provides 2 important factors to look at which are PA and link root domain. 1.Which one matters the most? or which one should I look at first to make a decision? 2. I have empty pages creating duplicate content with a PA of 14 and 1 linking root domain. my thought is to kill the page by inserting a meta NO INDEX. If you don't agree and think I should 301 to an existing page that needs link juice, let me know. Thank you mozzers 🙂

How to show a 'We are now...' message for a rebrand and do a 301 redirect?
Our developer wants to use javascript, document referral or adding a URL parameter, in order to show a modal window telling them 'We are now...'. A cookie seems to be too much work. All of which don't play nice with the search engines. Do you know of a technique or method that allows us to be SEO friendly and still give a good user experience? Thanks.
