It also support XML sitemap file building for your site contents including core site map menu urls, user profile urls, and popular plugin page view urls via site map channel API. Easy submit sitemap to major search engine like Google, Yahoo,Yandex, Bing thru Update Notification (ping) etc.. Is it a good idea to buy it ? PS: question could sound stupid but i'm newbie, any help is appreciated.
