Welcome to the Q&A Forum

Here is other couple of services for that: http://www.sharethis.com/ http://www.addthis.com/ These will also provide some sweet analytics for you I personally prefer the original buttons that you can grab here (with basic html or css knowlege you will align them as you wish): http://developers.facebook.com/docs/reference/plugins/like/ http://twitter.com/about/resources/tweetbutton http://www.google.com/webmasters/+1/button/

As I see it, Google needs to take no action on paid links. Well, no action different than devaluating them. While the market for paid links grows, the overall value and quality of each purchased link is deemed to go down. At one point people will stop bying them at all.

Tweetdeck's pretty much gone now

You could also consider placing the articles on your website and having publishers that pick it up linking directly to your site. I have a feeling that Panda will keep rolling out to a stage where links from content farms will be nearly worthless (IMO). Regarding the guest blogging, yes the search engines will see it as duplicate content but that should only affect them websites. For e.g If 2 high authority websites pick up the article, you will get 2 great backlinks and they will fight it out between each other in the SERP's

Thanks for this link & to break this MYTH that google accept that "first indexed is original"

A web crawler will start at the top of a page and work it's way to the bottom, discovering links and content on the way down. The first links it encounters will be used for anchor text association and weighed more then other links to the same page. Links in content are given greater weight then links in navigation so it is preferable to have those links discovered first. HTML code can be adjusted to position the navigation after the content. You can look at xenforo which is a forum software developer who designs their software in this manner. If you view the page's source code you will notice the navigation is at the bottom of the HTML code. With respect to your question on content structuring, there are many pages covering this topic. In general I have two pieces of advice. 1. Have your content reviewed by an English teacher. I am not looking for grammatical corrections (although that helps too) but more along the idea of properly presenting a topic. A good header, intro sentence and paragraph, etc. 2. Examine the wikipedia approach. Most wiki pages perform the basics of SEO content presentation very effectively.
