You have put lot of sweat in making your site. Now you want it to engender revenues and only source of traffic is search engines. You have completed your seo optimization well but there is no precursor of any traffic. Yes Google places new sites in "Sandbox" and this means that your site would not rank well for high traffic keywords for a certain period. This phenomenon is called as "Sandbox". What if your site is in "Sandbox" or on hold? Should you hang around or is there any way out. Lets look at few of them:

Have a slow and sturdy link campaign (taking Google new patent into consideration)

Google's new patent indicates some of the point clearly why many sites are thrown into sandbox for long. By keeping below points into consideration, you could shorten the time span of sandbox for your site.

# Go for everlasting link exchange. Don't buy links, which will evaporate once you stop payments.

# Have a slow and steady enlargement of links. Don't do it fast.

# Have a permanent anchor text in your links. Think well before you make use of one.

# Use multiple anchor text

# Have links from the pages, which are updated regularly

Start a PPC campaign

Get traffic from PPC campaign starting from Google Adwords and you could get instant traffic from the day you launched your site. You could work on your budget and come up with a figure where you could make some money after spending on Pay per click. In the mean time, you could make the list of keywords, which works, for you in the Adwords campaign and incorporate them into your site.

Add new pages

Get into habit of adding minimum of 1 content rich page to your site every day. This will not only prepare your site for higher traffic but also get your site crawled by search engines regularly. This could bring your site out of sandbox faster.
