I can't think of a good way to describe what I''m looking for so I'll just post this annotated image - http://i.imgur.com/1aHeT.png How can I dictate which pages will show up underneath my website on a Google search? Also, how can I manage the title of those pages as it appears on Google? Thanks a bunch!
Well Google will decide what is relevant, I presumed that they would use your Categories - but they choose random objects for my listing to... so to manipulate that - I have no idea and would only be guessing... maybe they choose what's relevant to your site and the search carried out? As for the Titles - That's easy - they use the title of content, be it a post, a page, a tag or a category... so always create good titles for your posts and pages... You can also use a meta tag for individual pages and posts - if you feel the need and if it's not automated (such as wordpress would be).
I'm pretty sure Google decides whether to give you extra links under your listing. It makes sense that they would choose the pages they seem as the most useful. As thsadmin says, make sure you use good titles etc
Also the title can be persuaded with the assistance of the Title Tag <title> and closing </title> - only use it once in a page! There's also <h1> and closing tag </h1> and so forth <h2> and closing tag </h2> - I barely use these as I use wordpress...
