Learn how having other relevant websites link to yours can improve your traffic
When your site is ready the first thing that Google recommends is that you "Have other relevant sites link to yours." This means as soon as your site is publicly ready for users to view your content and use your tools you should let other sites know you are online. This will help increase Web traffic to your site from other relevant sites and it will help your site gain importance. It is similar to your mailing address in the way that it becomes more important to you the more people have and use your mailing address. Also, it is increasingly harder to change your mailing address as more important people become accustomed to using it.
