Ok , Let's suppose i have a website http://www.abc.com. Every content on my website is unique and is of high quality. I create a network of free blog service providers (blogspot, wordpress, weebly). After this, i post rewritten articles on these free blogs and link them back to my website via anchor text. Is it a good way of getting back links or we will get some type of penalty?
Duolicate content will only be valued by google once, typically the first place that google crawled it. Therefore the backlinks may not provide any juice.
Any pattern based methods are not so good to build backlinks. Pattern means, suppose your are planning to publish all the contents on different platforms and probably you will link only to one or two of your sites (not to others), this will more look like a planned linking instead of natural one. It may or may not happen but I have just convey the idea.
I guess it's a bad idea. Even if you rewrite/spun your articles, google will trace it as a low quality link. Articles must be unique, always.
It's not appropriate to produce the links from our own web properties to rank high. Actually page rank is designed to recognize the website's reputation (real) in the web and to keep them in the top of the search results. So, google will be knowing that the links are from duplicated content and you get no benefit from such links.
@Tahira1966, I think you should read this article about the amount of penalties Google has been handing out. What you are describing is a Black Hat method. At first, web 2.0s were commonly used in wheels, but this became ineffective (easy for Google to detect). Now they are used in pyramids (similar to what you described), but I would guess due to how many penalties Google has notified about, this method is being caught on to (it won't be just the blog networks). With each Panda update they are improving their detection of spam tactics, so even if it does work in the short-term, it might then fall in rankings due to a penalty later on.
Well, quality does matter when it comes to backlinks... If the information is relevant to the web page, Google may ignore the duplicacy factor. According to your plan, the links you are going to get from blog network will be considered as poor quality links, it won’t give you much benefit.
