9 years ago I know I'm being a hardass, but it's how we're going to make you a bona fide web designer.
Meta tags are a good start, but also, if you want your site to look good on facebook when someone shares it, you have to put a few tags at the top. This site shows what Facebook sees when someone shares your site:
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fcardinaldesigns.info%2F
Notice how it picks a weird image to use? What I'd suggest is adding tags like such:
<meta property="og:type" content="company"/>
<meta property="og:title" content="Cardinal Designs"/>
<meta property="og:description" content="Getting started with Search Engine Optimization (SEO) can be a daunting task to the beginner. Explore how search engines work and the basic elements of search engine optimization."/>
<meta property="og:site_name" content="Cardinal Designs"/>
<meta property="og:image" content="http://cardinaldesigns.info/img/cardinal-logo.png"/>
<meta property="og:url" content="http://cardinaldesigns.info"/>I only know about this stuff because the link I gave you above asks you to put those in. It is however good for more than just facebook. A lot of sites use those tags to scrape your site. Note: The image you provide has to be a PNG or a JPG, SVG's don't work for the og:image tag.
Every time you make a change click 
and it should show you the new results.

At the top of your page, inside the HEAD, you should have some SEO tags so google can index your site better:
Add a description element and a keywords element.
<meta name="description" content="Getting started with Search Engine Optimization (SEO) can be a daunting task to the beginner. Explore how search engines work and the basic elements of search engine optimization."><meta name="keyword" content="search, engine, optimization, search engine optimization, SEO">http://www.htmlgoodies.com/beyond/seo/article.php/53671_3828801_2/Search-Engine-Optimization-SEO-Getting-Started.htm
