Step 1: using FTP create a folder called 'sitemap' on the installation/base folder (where your website is installed). Then create 'sitemap.xml' file under that folder. Give write permission (777) to both file and folder so, the magento can write/edit the sitemap.
Step 2: Goto: Admin / System / Configuration / Catalog / Google Sitemap
Here modify options as you wish and then enable 'Generation Settings'.
Step 3: Goto: Admin / Catalog / Google Sitemap
If you haven't created google sitemap beore, just click on the button "Add sitemap" which is on the right top of grid.

If you don't see generate link, then you can manually visit this link to create one: http://yourmagentowebsite.com/index.php/admin/sitemap/generate/sitemap_id/[Id of the sitemap from step 3]/
step 4: check your newly created sitemap at: http://yourmagentowebsite.com/sitemap/sitemap.xml and if everything looks ok, then add it to search engines. at: Google Webmaster Tools,Bing Webmaster Tools and other search engines.
