my website is www.articleslide.com does any body tell me that is my website is indexed on google or not ? if is it on google then why is it not updating regularly ?
It seems like your homepage is indexed by Google: http://www.google.com/search?hl=en&q=articleslide.com Put together a sitemap and submit it to Google Webamsters Tools. This should be a start.
You should add a sitemap to your site in google webmaster tools and you should build more backlinks this will help google to crawl your site more often.
