One really cool feature of MLM Gateway is the Business Announcements section.
Here you can post updates about your business.
You are permitted to include 2 links to your website.
So It makes perfect sense to use this feature to send traffic to your opt-in pages.
As an added incentive MLM Gateway rewards users with credits with every authorized Business Announcement.
These Business Announcement pages also pull traffic from search engines, so ensure you use related keywords and popular search terms.
Your announcements should be original content, so I would advise that you post your content here before you post it anywhere else, such as your blog.
