- 9. Canonicalization wwwvs.non-www <link rel="canonical" href=" http://www.1918.com/free-seo-classes-in-raleigh/" />

- 13. What is the current standard? XHTML 1.1 became a W3C Recommendation on May 31, 2001. CSS 2 became a W3C Recommendation on June 7, 2011. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html version="-//W3C//DTD XHTML 1.1//EN" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.w3.org/1999/xhtml http://www.w3.org/MarkUp/SCHEMA/xhtml11.xsd" > <head> <title>Virtual Library</title> </head> <body> <p>Content is <a href="http://example.org/">good</a>.</p> </body> </html>

- 22. What about my awesome web 2.0 ajaxiness?
- 23. How are you writing your ajax? <a href=“#”>Click Me</a> <a href=“javascript:someFunction(‘somepage.html#parameter=1’)”>
- 24. The Hijax Approach No javascript? You get this <a href=“somepage.html?parameter=1”onclick=“someFunction(‘somepage.html#parameter=1’); return false”> Got javascript? You get this This doesn’t work if you are trying to serve dynamic content
- 25. How Google wants you to write your ajax They want AJAX content crawlable without executing JavaScript <a href=“http://example.com/page?query#!state”> Special Hash Fragment http://example.com/page?query&_escaped_fragment_=state
- 26. RDFa, Rich Snippets, Microdata & other delights <div itemscopeitemtype="http://data-vocabulary.org/Person"> My name is <span itemprop="name">Bob Smith</span> but people call me <span itemprop="nickname">Smithy</span>. Here is my home page: <a href="http://www.example.com" itemprop="url">www.example.com</a> I live in Albuquerque, NM and work as an <span itemprop="title">engineer</span> at <span itemprop="affiliation">ACME Corp</span>. </div>
- 27. The Semantic Web is a "web of data" that facilitates machines to understand the semantics, or meaning, of information on the World Wide Web. It extends the network of hyperlinked human-readable web pages by inserting machine-readable metadata about pages and how they are related to each other, enabling automated agents to access the Web more intelligently and perform tasks on behalf of users.
- 28. What is Semantic Markup, or Meta-Data? Meta-data can be a difficult concept to grasp. So for example, here is some regular data: (+1)212 867 5309 Of course, most of us will guess correctly that this as a telephone number, but computer systems have no way of knowing that. They see it as a string of numbers – it could be anything! So that’s where meta-data comes in. <span class=”telephone”>(+1)212 867 5309</span>
