I have setup my WordPress site with Yoast.  However, it doesn't seem to appear in any of the search engines.  In Google Webmaster Tools I don't see a sitemap.  Is the plugin supposed to submit the sitemap and should it appear in Google Webmaster Tools?How do I know if it has been submitted to other search engines?
How to check if a WordPress SEO plugin is working
seo;wordpress;sitemap
SEO Yoast plugin will not automatically submit your sitemap.xml file on different Search Engines.Its just created a dynamic sitemap.xml for your site.You can find your sitemap here http://yourdoamin.com/sitemap_index.xml.after set up the Yoast you have do the following things.Allows robots.txt to crawl your site.Dynamically created sitemap should submit to search Engines (Google,bing etc)when you submit your sitemap to different search engines it will index your file you can check that with their web-master tools.In Google you can simply find site:yourdomain.com in the search, it will return Google indexed pages.Hope it make sense..
