Developer Grade SEO - part II
This document discusses best practices for developer grade SEO, including proper validation of code to current standards, clean and semantic markup, use of meta tags and microdata for rich snippets, and ensuring AJAX content is crawlable. It emphasizes starting with a clear site purpose and keeping code well-organized, validated and semantic to provide the necessary signals and metadata for search engines. While not absolutely necessary, following these guidelines can help sites rank better through clearer communication of content and structure to robots.

- 27. The Semantic Webis 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 SemanticMarkup, or Meta-Data?Meta-data can be a difficult concept to grasp. So for example, here is some regular data:(+1)212 867 5309Of 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>
