Made a nice package for a family friend who owns a business including SEO, Social Media management, and reputation management. He's rich and knows I'm still learning SEO so he's paying me anyway. He's more concerned with someone to update his social media pages and to post updates on the website. Here's my question. As I'm reading more and more I'm seeing the importance of writing a lot of articles and spreading them around on your website, web 2.0 sites, etc. The thing is, I don't want to spam this guys website and social media / web 2.0 pages with 10-20 articles a day, especially if the article is spinned and the keywords are blatant. I want to update his website / social media pages once a day with a quality article. Can I still add these articles to the back part of his website that isn't linked and that no one sees? Will Google still be able to pick these up if I don't have a link to them?
