Time will tell if fresh content draws attention. The only way to find out is to do it. :)
Paid advertising can help. Requires having funds to do that.
When guest posting do it respectfully and with full benefit of good content. This will encourage others to link to you.
Also allow time for your efforts to take effect. Things do not happen overnight.
Quality content is key. Provide the best content you possibly can. This will be your biggest time and effort.
Do not ignore outside advertising such as radio, tv, or print media. Skywriting also works to get a buzz going!
View your site logs month on month to determine where your traffic is coming from, and what quality it might be. Figure out what is human, bots, or scrapers.
