I created the website www.mytimecapsule.net, is a website where everyone can created their own time capsules. At the moment my biggest problem is promote the service. What are the best ways to do that? PS. If someone likes this project, I will accept partners to help in promotion, we will share the profits.
Probably a good start would be informing your friends and family, word of mouth is an excellent way of promotion and free. Depending on what you are looking to do? are you willing to spend money?
Since your site offers a service for general audience, you don't need to hunt for a highly targeted traffic. I guess you can expect good results from Facebook, Twitter and the like. Actually, any traffic source would do well. Just drive as much traffic as you can any way possible, and you'll be fine.
Use some article marketing ... but it's getting hard now due to new Panda updates... Facebook is a good way too.
create subdomain for blog the latest update, suggest information, experience in maintain and other excite info from your service. it will help to gain the visitor/user.
Put a feature for inviting friends. That way your current members will invite their friends and so on making it go viral.
A great way to promote a business like that is to have some video marketing done. I am currently offering a service on the forum for members to create video ads, submit and promote them. Its an excellent way to get some traffic and to get a boost for your business. Check out my sig link for more details.
Google likes fresh content and blog is a good way to do so.Add a blog to your domain and talk about your product,ask users to review your product ,use Twitter and FB pages to expose your site to the world.
I would like to suggest you to go strong and hard after social networking bring people from Facebook to your main website, educate them about your idea, social networking is the best way for you to find interested people and promote your website.
that kind of product makes sense trying a viral+PR approach. get some press releases out, ask some bloggers if they could write a post about it, offer people a free trial if they write about it on their blog, etc.
