I have 5 blog sites that I have recently established with unique articles I wish to publish there pertaining to my business website. The blogsites are independent, unbiased sources of news (i.e. not affiliated with any business - they are .org sites, etc.), however I wish to use them for boosting my business website on search engines any way I can. The articles on the blog sites will be written with the keywords that are most important on the business website. I realize that I can provide links to my website from the blog articles, but I don't want to seem unbiased on my blog sites.
I need an SEO expert to establish the tie from the blog site to my main business site. I need someone to figure out how to create these links, and manage this process for me using only best practices for doing so. Please explain your tactics and how you can help achieve this for me in your bid/post.
