The BLM system does just two things for your blog:
1) Brings more visitors to your site
2) If you already have enough visitors, allows you to monetize your blog and automatically increase its search position
BackLinkMetro is a system developed AFTER Google’s Panda and Penguin updates and accounts for these changes.
Take a look and see if this new system can help you reach the objectives you have for your blog: http://www.backlinkmetro.com
