Homestead won't do any advertising for you unless you are using the $49.99/month package.
There is a website called
iSubmit that will submit your website to over 300 search engines every month. It charges $50/month BUT the first month is free. So you can use it for one month and just cancel before the first month is up so you don't get charged. I wouldn't suggest this until your website is completely finished with keywords and everything.
Another way search engines find you is through links on other sites. This will cause the search engine to be aware of your site and will put it inline to crawl.
