SEO Plan for Large Authority Websites ?

Hi guys, I am just planning to start 1-2 authority websites

I want to ask how would you go about link building for large websites, by large i mean websites with more than 400-500 articles

I plan to have 400-500 articles on the site with each article targetting 1 keyword . (so 500 keywords = 500 articles)

I have planned to bookmark each article using senuke x.
some high pr ******** blog comments for each article (~20-30 for each article)

what else should i do?
Should i create link pyramid/push for each article so 500 articles - 500 pushes ? Isnt that too much

also do u receommend using blog networks like uaw/MAN after panda?

Please tell what strategies would you use for big sites

Thanks

If you are going to build a site that big I personally recommend only starting with one site and put all your efforts into it. Let your visitors know that your putting effort into your site. Create a twitter account and facebook and google plus account giving them all the same sort of theme so people distinctively know who you are. Show that you have authority and are the best site in your industry.

ya that big is a lot of work, start with 1 and just backlink like crazy

Linkpushing.net

I am also launching a big site soon with over 100 reviews and articles. I dont use any of this tool because they are monthly based and it require you to do work. I will just be paying for seo to my friend.

Another tip you really dont know how well the niche will work so start with only some keywords and see how it goes if its good then go for all those 500 keywords and more. Good Luck
