DNS vs IIS redirection
-
I'm working on a project where a site has gone through a rebrand and is therefore also moving to a new domain name. Some pages have been merged on the new site so it's not a lift and shift job and so I'm writing up a redirect plan.
Their IT dept have asked if we want redirects done by DNS redirect or IIS redirect. Which one will allow us to have redirects on a page level and not a domain level?
I think IIS may be the right route but would love your thoughts on this please.

If you are not changing the IP address you don't need to change the DNS, if you change the IP address, in addition to updating the DNS records you also need to properly redirect traffic from old urls to new urls.
With IIS the best option is using url rewrite, which is very flexible but a little tricky to set up if it's the first time you do so: http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module
Url rewrite does operate at web server level, its powerful and does the job, but you may consider doing redirects at application level, depending on the technology you use, php/dotnet/aspx/mvc you have different tools. The advantage of doing it at application level is you can redirect dynamically, in other words use an algo to translate the old urls to the new ones using whatever information is stored in the application cache, database, and so on. While using IIS url rewrite you either statically redirect each old url to a the new url or you use regular expressions or wildcards to dynamically do so. In other words using url rewrite you have a little less flexibility.

Within IIS you use the IIS Manager. Here's a blog on page-by-page: http://www.proworks.com/blog/2010/02/11/adding-a-301-redirect-in-iis-for-individual-pages-with-non-aspx-extensions/ It's older but still applicable.
There's also software available like ISAPI_rewrite that can help with the process if you're migrating between Apache and Windows servers: http://www.helicontech.com/isapi_rewrite
The Windows doc on this: http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/6b855a7a-0884-4508-ba95-079f38c77017.mspx?mfr=true

Thank you very much. What file would manage page by page or directory by directory redirects on an IIS server?

It sounds like you're talking about CNAME vs a 301 redirect.
DNS can't really "redirect", at least in the SEO sense. A CNAME DNS entry acts as a pointer to another site. Sooner or later you have to have an A record to act as the "glue" between yourdomain.com and an IP where it can be accessed. The problem is that yourdomain.com is the end result. So even if it is just a CNAME for loadbalancer.abc.some.cloud.com, it will be seen as yourdomain.com by both the browser and any robots that visit.
A 301 redirect is an actual instruction (HTTP response code) from the web server (IIS in your case) to the end browser, saying that yourdomain.com really belongs over at anotherdomain.com. At that point your browser (or crawling robot) goes to the new domain. This is considered the proper SEO way to redirect anything, as it is known that robots respect the 301 response and most SEO benefits that the previous link had will flow through the 301 to your new page.

Hi
If I understand them correctly....
DNS change would be the location for site x is now at this IP. (IP Location Change)
IIS change would be server y is now server x. (Hardware Location Change)
In which case an IIS change would likely be preferred as you don't have to wait for the new DNS update to propagate.
Hope that helps,
Don

301 Redirects, Sitemaps and Indexing - How to hide redirected urls from search engines?
We have several pages in our site like this one, http://www.spectralink.com/solutions, which redirect to deeper page, http://www.spectralink.com/solutions/work-smarter-not-harder. Both urls are listed in the sitemap and both pages are being indexed. Should we remove those redirecting pages from the site map? Should we prevent the redirecting url from being indexed? If so, what's the best way to do that?

PageSpeed Insights DNS Issue
Hi Anyone else having problems with Google's Pagespeed tool? I am trying to benchmark a couple of my sites but, according to Google, my sites are not loading. They will work when I run them through the test at one point but if I try again, say 15 mins later, they will present the following error message An error has occured DNS error while resolving DOMAIN. Check the spelling of the host, and ensure that the page is accessible from the public Internet. You may refresh to try again. If the problem persists, please visit the PageSpeed Insights mailing list for support. This isn't too much an issue for testing page speed but am concerned that if Google is getting this error on the speed test it will also get the error when trying to crawl and index the pages. I can confirm the sites are up and running. I the sites are pointed at the server via A-records and haven't been changed for many weeks so cannot be a dns updating issue. Am at a loss to explain. Any advice would be most welcome. Thanks.

Redirect root domain to www
I've been having issues with my keyword rankings with MOZ and this is what David at M0Z asked me to do below. Does anyone have a solution to this? I'm not 100% sure what to do. Does it hurt ranking to have a domain at the root or not? Can I 301 redirect a whole site or do I have to do individual pages. "Your campaign is looking for rankings for the www version of the campaign but the URL resolves as a root domain. This would explain the discrepancy. Since there is no re-direct between the two, you can have brickmarkers.com 301 re-direct to www.site.com which will prevent you from re-creating your campaign to track the root domain. Once the re-direct is in place it will take a while for Google to show the www version in the results in which your campaign rankings will be accurate." Thanks

Index.php and 301 redirect with Joomla
Hi, I'm running Joomla 1.7 with SEF on and I'm trying to do a htaccess redirect which fails. I have approximately 100 in effect so far and all working fine, but I have one snag. Index.php is not working as I need it to when it's redirected to www.myurl.com/ If I turn on index.php redirect to root using this code #index.php to root
Technical SEO | Aug 18, 2012, 6:53 AM | NaescentAdam
RewriteCond %{HTTP_HOST} ^myurl.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.myurl.com$
RewriteRule ^index.php$ "http://www.myurl.com/" [R=301,L] And then go to www.myurl.com/test.html I'm redirected to the homepage. I think this is because all pages are index.php in joomla. SEOMOZ and Google both think that index.php and root are duplicate pages. Does anyone have any advice for overcoming this? Thanks, Adam0 -
301 Redirect vs Domain Alias
We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
