Exponentially Increasing Duplicate Content On Blogs

[RCNOnlineMarketing]

Most of the clients that I pick up are either new to SEO best practices, or have worked with sketchy SEO providers in the past, who did little more than build spammy links. Most of them have deployed little if any on-site SEO best practices, and early on I spend a lot of time fixing canonical and duplicate content issues alla 301 redirects.

Using SEOMOZ, however, I see a lot of duplicate content issues with blogs that live on the sites I work on. With every new blog article we publish, more duplicate content builds up.

I feel like duplicate content on blogs grows exponentially, because every time you write a blog article, it exists provisionally on the blog homepage, the article link, a category page, maybe a tag page, and an author page.

I have a two-part question:

1. Is duplicate content like this a problem for a blog -- and for the website that the blog lives on? Are search engines able to parse out that this isn't really duplicate content?

2. If it is a problem, how would you go about solving it?

Thanks in advance!

With Wordpress you can no-index category pages, tags, author pages, archives etc.

Most of the SEO plugins let you do this, I know Yoast's plugin does it for sure.

Also make sure your site is using canonical tags and you should be good.
