Here is my thought on 2013 SEO Strategy.
1.Writing Quality Content & Distribution
I would like to say the best thing we can do for achieving better ranking in 2013 is still in hand of quality content, quality backlinks which are coming from trusted/High PR sites. Blogging is an important opportunity for content sharing & distributing over the internet community.
2. Implementing Google Authorship
This is one of the best option we can implement in 2013 SEO Strategy. Google authorship is a way for website authors to claim their written content. It gives Google a signal that the written content has purpose and comes from a real-human being. Getting authorship installed on your website is a snap. You need to claim a personal Google Plus profile, link your content to that profile, and place a snipped of code on your website.
