Duplicate content for manually setup blog and wordpress blog

[VizionSEO99]

We have a website where the ecommerce will not allow us to host blog. So we created our own manual blog page setup. Will this flag duplicate content on Google?

http://www.homesupershops.com/blog and http://www.homesupershops.com/blog-july have same content.

How come on a word press the same content on http://www.vizionseo.com/blog/ and http://www.vizionseo.com/blog/2011/05/how-can-your-business-rank-high-on-google-maps/ does not flag duplicate content?

Hi Vizion SEO.

How come on a word press the same content on ... does not flag duplicate content?

Why do you believe it does not?

Clearly it is duplicate content. When Google finds duplicate content within a site, they take their best guess to determine which page is the primary version for a given search, and they offer that URL in SERPs. There is not a "penalty" per se, although many people refer to it as such. Sometimes the page Google shows is not the page you wish to appear, and some may interpret that as a penalty. Also, your link juice would be divided amongst the various versions of the URLs rather then consolidated so that can be perceived as a penalty as well.

It is common for a home page to contain snippets of articles. That is what is happening on the vizionseo.com/blog page. It contains part of articles, and then you can click through to view the entire article. If you have a rather short article, then you can duplicate most of it's contents. This is normally not an issue as the home page, or main blog page in this case, has plenty of other content.

I will also point out you do have an issue on your site.

Both the above URLs point to the same page. The second URL is missing the trailing slash. This issue should ideally be resolved with the correct entry in your htaccess file on your server, but it can also be resolved by adding the canonical meta tag to your page. Until it is corrected you have a second form of duplicate content on your site.

Your /blog page is duplicating both of the entire articles from July. Your navigation, footer and both side bars are identical also on the pages. Clearly only one of those pages would be listed. I would recommend reducing your /blog page coverage of articles to the first ?200 words or so. You can offer a teaser of the article with a "continue reading..." link.
