Editor's Notes
- Thank you for coming\nThree SEO sessions going on. Glad you chose this one.\n
- This is the developer track\nYou can write HTML (all about markup)\nYou can customize a WordPress theme or write your own\n
- Google was unveiled in 1998 along with pagerank algorithm\nAuthority from inbound links and the words they used\nEasily gamed by building link farms, selling links\n
- As Google grew, an ecosystem of SEO experts & tools grew around it\nSnake oil salesmen too\nGoogle wouldn&#x2019;t tell us anything\nFelt like a game of Calvinball as we tried to figure out Google&#x2019;s rules & work around them\n
- Named for Google engineer Navneet Panda\nWent after low-quality content that ranked highly, link farms\n\n\n

- Search engines are sick of our games\nJust want to deliver content...\n
- Google, Bing, others\nPreferably without even sending them to our sites\nReviews, prices, maps, deep links\n
- author & publisher links to Google+ proflies\nHTML5 semantics: article, nav\nMicrodata\n
- Google & Bing came up with a standard for Microdata.\nYahoo! came on board shortly thereafter\nYandex is Russia&#x2019;s biggest search engine\nschema.org website & blog\n
- Microdata lets us describe the &#x201C;things&#x201D; that make up our web pages\nNouns\n
- Blog entries, Comments, Maps, Reviews\n
- &#x201C;Real world&#x201D; entities like books, TV episodes, and Medical Conditions\nIn fact there&#x2019;s a whole set of schemas for conditions, treatments, medical offices, and the like added late June\n
- You can get really specific. Motorcycle dealers, Zoos, High Schools\neven Gated Residence Communities\nSearch engines will see these declarations and organize appropriately\n
- About 550 schemas\nA full list of schemas is available at schema.org\nSo, how do we use it?\n
- Microdata is part of the HTML5 spec.\nThis lets anyone to make their own schema, but search engines wont recognize it\n
- Any tag that can have children, including BODY, can represent an item\nItemscope declares the tag to be an item, itemtype points to the schema\nUnless you tell otherwise, the BODY is assumed to have a WebPage schema\n
- schema.org descries the fields in detail, specifies a hierarchy of schema types\nschemas inherit fields from parents\nfields have datatypes that are other schema types\n
- Fields are noted with itemprop. Can appear on any tag.\n
- Complex datatypes are instances of other schemas, include their own fields\n
- For example, our Movie features an actor\nan actor is Person\nand a person has a name\n
- Meta can now to live anywhere in the page\nIt&#x2019;s there to provide metadata on the &#x201C;things&#x201D; in your page\nMachine readable alternate values like Time\n
- Meta can now to live anywhere in the page\nIt&#x2019;s there to provide metadata on the &#x201C;things&#x201D; in your page\nMachine readable alternate values like Time\n
- Meta can now to live anywhere in the page\nIt&#x2019;s there to provide metadata on the &#x201C;things&#x201D; in your page\nMachine readable alternate values like Time\n
- Sometimes you want to include information for the search engines\nbut not have it visible\nhtml5 gave new life to the meta tag\n
- Our movie was release on June 1st, 1990\nISO 8601 date for search engines\nText date for people\nCan specify more precision in meta\n
- Once you&#x2019;ve added the microdata to your HTML, run it through a validator\n
- \n

- We ran a test on straightnorth.com and reported in our blog\nAdded microdata to our executive profiles\nRan through validators\n
- Google uses SOME microdata to add rich snippets,\nhaving it doesn&#x2019;t affect rank\n
- Bing does let microdata affect rank\nFOUR WEEKS LATER\nthey indexed us for additional terms\nour rankings went up\n\n
