How frequently: Depends on how often you update your site.
First, submit your site to Directories (not search engines)
What you can do: Create a blog and ping, and submit articles to sites like ezinearticles.com; spider go every day to their sites, and they will then spider your site when they find your link.
Spiders crawl constantly. Often every day, multiple times a day. They may come pull a few pages. Then come back pull a few other pages later in the day or the next day. The fact that they crawl does not necessarily mean they will include the site in their database index or that it will be ranked well on your target keywords.
