Redirect Multiple Domains
-
This is a follow-up question from one posted earlier this month. I can't linked to that because it's a private question so I'm trying to summarize it below.
We have a number of domains – about 20 - (e.g. www.propertysharp.com) that point to our main domain ip adress (www.propertyshark.com) and share the same content. This is no black-hat strategy whatsoever, the domains were acquired several years ago in order to help people who mistyped the websites url to reach their desired destination.
The question was whether to redirect them to our main domain or not. Pros were the reportedly millions of incoming links from these domains - cons was the fact that lots of issues regarding duplicate content could arise and we actually saw lots of some pages from these domains ranking in the search engines.
We were recommended to redirect them, but to take it gradually. I have a simple question - what does gradually mean - one domain per week, per month?

We did not get more details on that - I assume it may raise some flags if you suddenly redirect 20 domains. I'm not sure if or why is that, that's why I decided to ask a follow-up question.
Btw, thank you both for your replies!

Definitely 301 redirecting them is the way to go. Make sure each page on the redirected domain maps to the corresponding page on your main domain.
It sounds like you know a few pages on these domains you want to redirect that rank well. I'd pick one of these domains to start with, and redirect all of its pages to the corresponding pages on your main domain. Wait until Google reindexes those pages that rank well, and try those searches again. That page on your main domain should rank at least as well as the page on the old domain, and hopefully even better since their link juices are consolidated.
If you're highly risk-averse, you can continue doing this domain by domain. Otherwise, you can batch them and do several at once, or just redirect the rest of them. Just make a note of the searches where pages on these other domains were doing well, and check that those pages on your main domain does just as well after those pages get reindexed. Personally, if it worked for one, I'd feel pretty safe doing all of them, and then keep checking the SERPs afterward to make sure nothing bad happened.
How gradual the process is will be determined by how quickly the pages are reindexed. If they're reindexed quickly, you'll be able to see if it's working and can keep moving forward.

What was the idea behind gradually redirecting the traffic? I am not aware of any harm with fully implementing the redirects right away.
You can also add the canonical tag to the duplicate pages indicating the URL of the page on your main site. This would allow you to keep your existing sites if you so desired, but only having your main site appear in the search index.

301 Redirect back to original domain
We have a site, domainA.com and we split part of the site off into it's own site a couple of years ago as domainB.com. All urls from DomainA were 301 redirected to DomainB, but with a different folder structure. For business reasons, we now shuttering domainB and rolling it back into domainA. For the 301 redirects for urls that were on the original domainA, should I overwrite them to the new folder structure directly from the original urls? In other words: 301 redirect domainA.com/oldstructure to domainA.com/newstructure rather than: Existing 301 redirect domainA.com/oldstructure to domainB.com/newstructuretopic with a new 301 redirect to domainA.com/newstructuretopictopic

Redirecting the .com of our site
Hey guys, A company I consult for has a different site for its users depending on the geography. Example: When a visitor goes to www.company.com if the user is from the EU, it gets redirected to http://eu.company.com If the user is from the US, it goes to http://us.company.com And so on. I have two questions: Does having a redirect on the .com will influence rankings on each specific sub-site? I suspect it will affect the .com since it will simply not get indexed but not sure if affects the sub domains. The content on this sub-sites are not different (I´m still trying to figure out why they are using the sub-domains). Will they get penalized for duplicate content? Thanks!

Multiple (different) domains and canonicalisation
Hello, We've had experience with canonical tags for various domains before, such as tidying up product categories etc... However, can anyone point me to any guidelines about different domains using canonicalisation. For example: If I had the following sites, all with identical content - exampledomain.com completelydifferentdomain.net anothertotallydifferentdomain.com With canonical tags pointing to the first one (exampledomain.com), could this be harmful? Is it better to 301 redirect the other sites? Thanks

301-redirect
Hi My website is fairly new and i wasnt aware of the difference btw 'website.com' and 'www.website.com' when i started up. It doesnt matter which one i use as long as i am consistent right ? Most of my ingoing links are to mainpage on 'website.com'. I have som ingoing links to 'www.website.com' but also some to 'www.website.com/brandname'. is it enough to 301-redir 'www.website.com' to 'website.com' or does it need to be done on several levels ? I need to have someone do the redirect for me - how can i check its working when its done ? Dan Lærum

Parked Domain blog directory not redirecting
My newly parked domain name, (our main website had to switch primary domains) is not redirecting properly and is causing our blog to be duplicate content. My 301 redirects work for everything else, but our parked domain /blog directory is not redirecting. I can type in both urls and then the blog appears on both sites. Not good. If I delete my blog .htaccess file, then it redirects fine. However, then our blog links are broken. So it has to do something with our .htaccess files. I do have a .htaccess file for our website, saying redirect everything to correct location, so i think this is interfering, but I cannot pinpoint it. this is the .htaccess file for the blog. BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On

Query String Redirection
In PHP, I'm wanting to store a session variable based upon a link that's clicked. I'm wanting to avoid query strings on pages that have content. My current workaround is to have a link with query strings to a php file that does nothing but snags the variables via $_GET, stores them into $_SESSION, and then redirects. For example, consider this script, that I have set up to force to a mobile version. Accessed via something like a href="forcemobile.php?url=(the current filename)" session_start(); //Location of vertstudios file on your localhost. Include trailing slash $loc = "http://localhost/web/vertstudios/"; //If GET variable not defined, this page is being accessed directly. //In that case, force to 404 page. Same case for if mobile session variable //not defined. if(!(isset($_GET["url"]) && isset($_SESSION["mobile"]))){ header("Location: http://www.vertstudios.com/404.php"); exit(); } //Snag the URL $url = $_GET["url"]; //Set the mobile session to true, and redirect to specified URL $_SESSION["mobile"] = true;header("Location: " . $loc . $url); ?> Will this circumvent the issue caused by using query strings?
