For instance, if you host your blog on Wordpress, it is good to install Wordpress sitemap plugin which is a good tool that automatically updates your sitemap and send notification to Google. Google offers free sitemap creation tools, so do not worry if your hosting website does not offer you any software. Without sitemap, you can still submit your blog on Google Webmasters. Google drags results from blog directories, so it is good to submit your blog on these blog directories, and ping your site when you revise your blog. There are many websites which offer you this service, but Feed Shot is the most powerful website which submits your blog on main blog directories.
