Guest posting

After Panda update many are using Guest posting strategies for back links and of course for traffic.
Is it necessary that our article should be unique when guest posting?
Whats your opinion on this?

Yes it has to be unquie or they wont allow it on there blog most of the time.

With any kind of posting, your blog post or article will need to be unique. I think that it wouldn't really make bloggers happy if you gave them spun content, and I am pretty sure they check beforehand as well until a certain level of trust has been built.

Of Course its very important to have post with unique and at the same time high quality content. Good quality content only tends to bring quality backlinks and traffic.

Guest posting is, indeed, one of the best post panda strategies.

As long as you are doing it in right way i.e. you must not offer same blog post on different blogs, otherwise it will be like another article marketing strategy.

Offer quality posts on other blogs, this will help you in improving your traffic, exposure and credibility.

You can use ‘Keyword Country’ for finding celebrity blogs of your niche so as to approach them for guest posting.

Content duplicacy is almost dead after panda 2.3 updates. webmaster has only 2 options...either you use original content or Google will kick your site out.

Regarding Guest Blogging:- This link building method is in demand after Panda update but without original content, you can't take advantage of this link building method.

I use it for traffic more than links if the blog is reputakbe at all. It is them giving you a page on there website.

I would say that it has to be unique and also of a really high quality. If a blog is accepting poor quality posts then the links probably aren't worth having (in general terms).

yes, panda is mainly for content so we should be careful to the content, on our website and for link building as well.
