Should I check Use noindex for Tag Archives?

[vinner-280241]

I have a page indexed > (http://mysite.com/mypost) and also http://mysite.com/tag/mypost The same post shows up twice, one with /tag/ one without when I search site:http://mysite.com
Is this a duplicate content?? Can I get penalized for this?

In the All in one plugin should I check Use noindex for Tag Archives to avoid this or doesn't matter.
Thanks

Most of my sites uses Wordpress, what I did to never have any duplicate content is the following:

First, I have the following plugins installed

• .html on PAGES
• All in ONe SEO Pack
• cbnet Ping Optimizer
• Google XML Sitemaps

Then, added the following text to the robots.txt

User-agent: *

Disallow: /wp-adminDisallow: /wp-includes

Disallow: /wp-content/plugins

Disallow: /wp-content/cache

Disallow: /wp-content/themes

Disallow: /trackbackDisallow: /comment

Disallow: /categoria//

Disallow: */trackback

Disallow: */comments

Disallow: /sem-categoria

Disallow: /pollsarchive

Disallow: /category

On the admin in the PERMALINK config tab, in the COMMON SETTINGS i choose

• Custom Structure -> /%postname%.html

In SETTINGS > cbnet Ping Optimizer I inserted

I use this plugin to make sure that wordpress will not ping those services everytime I change or update something on the page,actually I seted the plugin to ping only after 30 min after the last ping.

So If you just posted something on Wordpress it will ping all those services for a fast index, however, if for some reason you have to edit the post when you save this plugin will make sure the services will not get pingged again in such a short space of time.

In the All in One Seo config I have the following config

UNCHECKED

• Use noindex for Categories
• Use noindex for Tag Archives
• Autogenerate Description

I also set Exlcude Pages, Additional Post Headers, Additional Page Headers and Additional Home Headers all blank

With all this configuration if someone access any post of my blogs they get a page with http://domain/post permalink structure, doesnt matter if the access came from a TAG, Categorie or normal Search.

Aditionally the main Tag page and Categorie page are indexed, so i ended up using my tags for some sort of relevance to the posts that belongs to that Tag. In google search the same post could appear by many related TAGs filter but the content of the post appears in an unique page.

Hope that helps

PS.: Suggestions to improve this config are welcome

Hey, I am guessing this is a wordpress site?

You could solve this a couple of ways

1. 301 redirect the duplicate page - not recommended as it is a valid page but it may work
2. canonical link on both pages showing the main version of this content
3. noindex the tag page

Alternatively, you can use options 2 & 3 and it will resolve it.

If it's wordpress, happy to take a look at the actual page if it helps? I spend a lot of time tinkering with wordpress so there  maybe another way & this answer is based on some assumption without real links.
