Hello, I want to build tier 1 with web2.0 websites for multiple keywords. I have done with one keyword before, posting articles on 10-12 web 2.0 blogs with backlink to my website. But this time I have multiple keywords to link back to my website. So is it ok to create one article for each keyword on the same web 2 blog and link back to my inner pages ? For example main keyword is 'party planning ideas', other keywords would be party planning for kids, surprise party, party planning for pet. So, can I write three different articles on the same blog and link back to my three different pages(related) or should I create different web 2.0 blog and write article for each keyword and link back ?
