WordPress Reading Settings Control your frontpage Settings
Front Page Display Setting choose what content appears on your website’s front page. Choose to have your latest blog posts or a static page. Created in the Pages tab (black bar left hand sidebar) of your site.
Your front page is set to display your latest blog posts by default, this can change it to a static front page. Using a static front page is handy if you want to use your front page as a landing page.
Blog pages show at most – Controls the number of Posts to display on your blog page. If frontpage display is set to display Your Latest Posts this value is controlled here also.
Syndication feeds show the most recent – These feeds show the most recent items and lets you set how many blog posts will be sent out at via RSS feed (mine is located at http://pinguisweb.com/feed/). Add /feed/ to your wordpress domain name to get your feed address.
For each article in a feed, show – choose whether to show all post content or the first 55 words, you can select Full text or Summary. Full text means that the entire contents of a post are included in the feed. Summary means that only the first 55 words are included in the feed, along with the option to continue reading the rest of the post. Best change to Summary because of pagespeed and bandwidth factors.
Search Engine Visibility – If you want to setup your website before indexig check the Discourage search engines from indexing this site box to ask search engines not to index this site. When the option is checked, this changes robots.txt to send back noindex(Disallow) commands to search engines.
