You are in a danger Chris; my advice is to kill the contract immediately as they are selling the snake oil services and nothing else.
- One article and submitting on different article submission websites, you soon will e the victim of Google penguin update. This is indeed a duplicate content plus Google don’t really like the links coming from article submission sites.
When buying link building services from any company always keep few things in mind.
- If someone guarantee certain number of links in a certain time, you probably should question their quality as link building in most cases cannot be time specific.
- Press Release links? Google don’t like it unless the links are no-follow.
- Social Bookmarking links :O. I would not even consider them quality links.
- Web Directories, unless they are highly relevant to your business and contain quality, its again will hurt you.
