Are you still worry about your website has duplicate content issue in search engines. We all know Google hates duplicate contents, waste bandwidth and them indexing power. So Google will filter all duplicate content, sometimes even a penalty will follow. Now, you can avoid duplicate content issue from beginning. Choose either www domain version or non-www version. Either will work great, but which one will you decide to use, are totally subject to your personal taste. http://referer.us/301-Redirection.html is a new tool part of famous Referer.us No Referer, and Fake HTTP Referer service. An "A" record in your DNS is all you need to get the redirection work. The redirection is instantly, no delays on client side. The redirection is 301 Moved Permanently ( a redirection method will pass any ranking and PageRank in Google terms ), all URL path and all parameters ( the querystring ) will be unchanged. The service is totally free.
For everyone who is confused... EXAMPLE: www.acubs.com is different than acubs.com because with the www, it is considered a subdomain.
I will add one more thing. Ex- Some site use home page url like http://home.com http://www.home.com/ http://www.home.com/index.php http://home.com/index.php If these were not redirect to one preferred domain, then it can create many dupluicate content.. am I right ?
It will but it can be avoid (without using the 301 redirection I provide) 1. make sure your page has canonical meta, with correct value you prefer, for example <link rel="canonical" href="http://www.home.com/" /> 2. make sure all 4 URLs you listed above display exactly same content (in html code) then everything will be fine.
Thank you DoDO me for making it clear to everyone.. Very few people take notice of canonical meta tag.. recently Google wrote a post on it in its webmaster central blog..
Interesting and smart service. Thanks for sharing I know I withheld the www on some links to major websites. I will have to rethink this. Cheers.
You don't need the canonical meta tag. Just always refer to your url and home link the same way. e.g. www.mydomain.com/ (After you fix the with www vs non www version issue with a 301 permanent redirect in the .htaccess file) If one links to a url or types it (www.mydomain.com) the server will look for the index page (or the one named default, depends on how your hosting is set up) therefore you don't need to refer to it. Same goes for folders. www.mydomain.com/foldername/ the server will look for the index page. If there isn't one, it shows a list of folder contents, which can be a problem if the folder contains stuff you don't want people to see.
thanks every one. Just add ports support in this free service, now ports like 81, 82, 8000, 8001, 8002, 8002, 8008, 8080, 8088... will be handled. Check all ports list http://referer.us/301-Redirection.html canonical meta is not a must, but it was recommended by Google. Since Google rules, we better use it. yes, you can always refer your url as the same way as you wish, but you cannot control all others do the same way. For example, if you submit the domain to site like Alexa (or other server/host information sites), it will check the both version, www one the no-www one, so Google will pickup your both URLs from there, and claw both version from all your internal links. (it can be avoid by use base meta, I believe most of you not know what it is) Use .htaccess to change from www to no-www (or no-www to www) is a very common practice and most of most people use that. However, for non-gurus of .htaccess , it's not easy to handle all ports, paths, parameters correctly. Our service is just a smarter and easier way, one "A" record, solve all your headaches.
Have never used the canonical meta tag ever. With the 301 permanent redirect in place for the version of the url I want to use never had a problem with pages being indexed incorrectly either.
for static page, yes. for dynamic page, might not. Because when google access the two different page, the content might be different.
