Thread: Duplicated content within a website-How to avoid

Hi all

I have duplicated content in my website: I have my site with www and without www and the second one do not redirect to the first.
I was trying to fix the problem using the canonical atribute, but I don´t know if thats enough and in addition I would like to use htaccess to fix the problem.

Does somebody know how to do this?

thank you in advance

Every time I create a site my webhost creates a .htaccess file in the public_html folder of the site, then I just add these lines to it and it redirects to www. Make sure every line is on a new line.

RewriteBase /
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mywebsite.com
RewriteRule (.*) http://www.mywebsite.com/$1 [R=301,L]

Hi pagerank7

Thank you so much for your prompt answer.
I will try it.
I am a little bit worried, because some people told me thats quite dangerous if made false.

If you have cpanel hosting look for 'redirects' under the domains section. There is a dialog box that allows you to write the redirect to your choice of www or non-www. The syntax will not be a worry if you use the wizard based rewrite tool.

Ok, I will take a look at the control panel of my hosting service. Otherwise I was trying to set my domain with www on google webmasters tools, but I don´t know if thats enough.

Thank you for your answer

Actually,i don't know what is the prosier to avoid the duplicated content within a website.So please give me the some information on it.

The www and non-www addresses for your site are considered two separate URLs by search robots. Therefore you should choose one and use it in all of your backlinking efforts. It does not make a difference which you choose, just be consistent. Put up a 301 redirect as described above so that traffic for the alternate is redirected to your chosen URL.

Many CMSs also list the same page by several different URLs. In Wordpress you can search by tag, category, archive date, and probably a few other ways. Each of these returns a different URL. Google introduced the canonical meta tag to tell which is the original content. Some, if not all, SEO plug-ins write the canonical tag to avoid this problem.

I used the canonical meta tag to fix the duplicated content problem of my website and I hope thats enough. I set also my site with www on google webmasters tools.
Only if these measures are not enough I will use htaccess.

Non www to www redirect will get get solve by Canonical tag, You need to do 301 permanent redirect. You need to make changes in Htaccess file and then upload it this proble will get resolve.
