A quick, no explanation reference on how to optimize blog posts and blogs for search engines.

##Meta Tags

Meta tags go in the <head> of an HTML document. They add additional information/context to the current web page or website.

<!-- Update your html tag to include the itemscope and itemtype attributes. -->
<html itemscope itemtype="http://schema.org/Article">

<!-- Place this data between the <head> tags of your website -->
<title>Page Title. Maximum length 60-70 characters</title>
<meta name="description" content="Page description. No longer than 155 characters." />

<!-- Schema.org markup for Google+ -->
<meta itemprop="name" content="The Name or Title Here" />
<meta itemprop="description" content="This is the page description" />
<meta itemprop="image" content="http://www.example.com/image.jpg" />

<!-- Twitter Card data -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@publisher_handle" />
<meta name="twitter:title" content="Page Title" />
<meta name="twitter:description" content="Page description less than 200 characters" />
<meta name="twitter:creator" content="@author_handle" />
<!-- Twitter summary card with large image must be at least 280x150px -->
<meta name="twitter:image:src" content="http://www.example.com/image.html" />

##Semantic Markup

Does your websites HTML markup contain a large number of <div> elements?!?! Use HTML tags that are more semantic/descriptive of the content they contain! <div>s can be replaced with…

<article> <aside> <details> <figure> <figcaption> <footer> <header> <main> <nav> <section> <summary> <time>

Mostly self explanatory, but there are a couple rules to how these should be used. For some direction, try reading my more in-depth post on HTML5’s sectioning elements.
