More Unique content with less keyword density is the best revenge from Google..

Private High Page Rank Blog Network

I dont think you can define "the best seo" but basically you are right about wikis and those sort of links.. videos are hot for sure, and the whole sphere is moving toward genuine, natural linking.

Yeah I think Video Marketing is going to be the big thing in 2013. I also think it can be a big money waister. You can spend a lot of cash and not get the necessary mileage out of video marketing

link from the high authority sites will give best result for seo work

Unique and original content and quality backlinks from related sites.

Guest blogging is the link building strategy which is going to rule 2013. It have already shown its demand and the demand is increasing everyday.

which link building tools are you using ?

I think, Video Promotion and Social Signals will be important for SEO 2013.

My tactic is very similar to yours.

- quality content, updated on a daily basis. Tip: I also encourage my visitors to share it on their social profiles. Google will pay even more attention to social signals in 2013.

- guest blogging. I write a lot. I am constantly in search for a new and quality blogs which accept guest posts. Tip 1 - use co citations in your articles. If your content isn't strongly connected with your anchor Google it value it less than it valued before Panda update. Tip 2- Use "I " a lot. That way you will personalize your article more, which will give you higher authority, especially if the content is very informative. Tip 3 - quality over quantity. Try to find great blogs related to your niche. If you have a real estate niche, your article about SEO with real estate keyword in your anchor simply won't be valued highly from Google. I've tested it. Either you will write an article about real estate or you will write something like "SEO+RE" article...for example "Top SEO Tips for real estate website" . Tip 4 Take a closer look about the blog on website you want to write a guest post. Sometimes website can have a great PR and a lot of inbound links, but blog has a low value because of not spreading the link juice. Don't just rely on a PR for a home page. I also suggest to check website in Open site Explorer in the "compare metrics" section. Sometimes people just make big network of their own blogs and link to each other. For example, the website can have 100 linking root domains, but if they all are coming from 7 or 10 C blocks (which can be checked in a "compare link metrics" ) thart website is less value than other who has 50 linking root domains but from 40 c blocks. Bootom line - you need to check a lot of things. Maybe it seems like a waste of time, but believe me, quality over quantity. I know many people would trade their hundreds of submissions on a various directories for one submited in Dmoz. I will repeat for the third time - qualituy over quantity. Same goes for guest blogs as for the directories.

- video marketing: great way to promote and to gain more backlinks. again, quality over quantity. great "onsite video SEO" is important but if you don't stand out from the crowd with some creative and easy-to-remember video clip, no one would share it. Instead of making hundreds rehashed videos per day, make one, but unique and worthy.

- beside these three methods (quality content marketing with social signals, guest blogging, video marketing) you can diversify your backlinks with various methods such as low valued (but still needed because of diversifying) forum posts, blog comments, etc.

if we new what was going to be important then we would never need to wory about Google and algorithm changes but the reality is we do not know what they are going to do. The only way to protect yourself if through a private network.

You have shared some useful info with us.
I believe your tips are enough to get good page rank.

I do agree with you on certain points that you have made on your post!

I would also like to suggest that diversifying your backlink profile will be key to ranking. Because it will look 'Natural' to Google robot. So I will not stress on any particular type of link building but will build backlinks from various relevant sites/source for natural diversification which will surely include the social signals as well.

Really solid plan and that's basically what you have to do nowadays
