After using Google Analytics for few months, we are very happy with it. Today we knew about Google webmaster central. This site contains lots of webmaster resources including tools that helping to improve traffic to our site.
After we start to use the site, we realize that we need to have Sitemaps in my site. We found this WordPress plugin, Google XML Sitemaps. This WordPress plugin will auto generate a XML sitemap whenever the content of the site is changed. Both sitemap.xml and sitemap.xml.gz will be generated at the root folder after activating the plugin and clicking the setting to build the files for the first time. Then at Google webmaster central, we need to verify our site by inserting meta data on WordPress header template file. Google webmaster tools will auto detect the sitemap file of the site. The rest will be exploring other features available in Google webmaster tools.
