When you submit a piece of content to del.icio.us, take the time to write a great title for it. Many del.icio.us users will see your submission and decide whether or not they want to click on that bookmark to read the original content or bookmark it themselves based solely on the title you give it.
2. Add a Great Description
Don't stop at writing a great title. When you submit a piece of content, take the time to write a description that will entice del.icio.us users to click through to read the original content or bookmark it themselves. Make your submissions too interesting to pass by with great descriptions.
3. Use Relevant Tags
If you want other del.icio.us users to find the content you submit, make sure you tag your bookmarks intuitively. Think of what tags other users would search for to find content like what you're bookmarking, then use those tags in your bookmark submission. The content you submit doesn't have a chance to generate any interest and traffic if no one can find it.
4. Ask for Bookmarks
When you write a great blog post, ask your readers to bookmark it. Send an email or Twitter your friends and ask them to bookmark it, too. Install the del.icio.us Tagometer which will show your readers how many people have bookmarked your posts. When people see that others are bookmarking a post, they'll often join in and bookmark it, too.
5. Make Friends
Build a network of friends on del.icio.us. Follow other users, bookmark their content, and develop relationships with them. A strong group of del.icio.us friends can have a powerful influence in terms of drawing attention to bookmark submissions.
