During the September 11 edition of #AskGoogleWebmasters, Webmaster Trends Analyst John Mueller sad that JSON structured data can be inserted into both the head and body of your pages.
Here was the question – “Is it possible to insert JSON structured data at the bottom of the <body> instead of the <head>? It seems to work fine for many websites,” asked user @largow via Twitter.
In response, Mueller said that you can insert JSON structured data either in the body or the head. There were three structured data formats that Google supports, according to Mueller. They include:
- RDFa, “an HTML5 extension that supports link data through additional attributes added to existing HTML tags on the page,” Mueller described.
- Microdata, “an open community HTML specification used to nest structured data within HTML content. Like RDFa, it also uses HTML tag attributes for this.”
- JSON-LD, “a JavaScript notation embedded in a script tag in the page head or in the body. The markup is not interleaved with user-visible text, which makes nested data items easier to express.” Mueller also mentioned that this format can be injected into you pages via JavaScript.
Of course, rich results aren’t going to go anywhere, so make sure you adapt your effort to the search results page. One way to do so is structured data implementation. Knowing the formats that search engines support as well as how they process your structured data could increase your visibility.
