I have a website or you can say an App. I want to invite/register business owners to sell their products or services through my website/app. In the mean time I also want to attract consumers to buy the products/services using this app/website. What will be the effective to achieve my goal? What should I do to promote this app/website? The website/app is almost ready to launch. We are working on pre-launch promotion using social media, e-mails and a few SEO activities like forums, comments, Q&A, blogs etc. What else can we do to get effective results? Please share your creative thoughts.
