Host good content and inform Google, which allows you to submit your site or blog for indexing.
Google crawls all over the net and will sooner or later find your site. But to index quicker in the search engine, go to http://www.google.com/addurl/ and add your website url.
Although this does not guarantee that it’ll crawl your site or show it in the results, it’s better than not submitting.
You can add the home page url and also put in a few sentences about the content of your site. Or you could submit the keywords of your blog or site.
Seo4Google.org’s Tip: To index faster in Google, write an article in a site that gets crawled frequently (news sites etc). Get your author’s bio at the bottom with your url and when Google search engine visits that page, it will also visit your site from there.
Another way to get Google to visit your site is to request bloggers or webmasters (friends or otherwise) to review your site. So that search engines can crawl through your website url from that blog.
Social media is another option to get your site indexed faster in Google. Submit good quality pages to Digg, Reddit or propeller. Since these sites are visited many times in a day by search engine bots, chances of indexing are higher.
