Schema Markup Best Practices – Json-LD Vs Microdata

Appearing on the first page of Google is an all-consuming ambition for a digital marketer or a business. Schema Markup is one of the approaches that is not very new, but relatively under-exploited by websites to improve their presence in SERPs.

What is Schema?

In 2012, top search engines (Google, Bing, Yahoo, Yandex) agreed on accepting schema vocabulary for highlighting content on web pages. Schema is, therefore,  a standardised mark-up for a webpage content that is well recognized by search engines for helping website improve its online visibility. Its use makes complex data structured and presentable. Currently. vocabulary is compatible with Microdata, RDFa and JSON-LD markups, not Microformats. Its popularity drifted from travel and hotel industry to content world and today can be applied to most of the industries.  You can check the complete list of items that can be markedup.

Remember, structured data, schema and markups and rich snippet are different.

Why Schema Markup is Important for Online Presence?

  • Recognised by major search engines – Google, Bing, Yahoo, Yandex.
  • It helps in generating rich snippets in search engine results.  Rich snippets for breadcrumbs, reviews and ratings, person, brand, author, music, event, live webinars and lot more.
  • Improve the way content is displayed in search engine ranking results

What is Structured Data?

Structured data is a method of pairing a name-value to help search engines categorize and better understand your content and index it.

Markups Used for Structured Data Implementation

RDF (Resource Description Framework) : RDF has two versions RDFa and RDFa Lite. These are inline markups applied to HTML documents with structured data. Both RDF and Microdata are similar as they define attributes that are added to the HTML.

Microformats : Microformats are used to markups web page elements using HTML markups. It reuses existing HTML tags mainly class attributes.

I won’t dwell on RDF and Microformat. My focus in this article would be on two popular and easy to implement schema formats Microdata and Json-LD.

Microdata : Microdata is a HTML specification used for semantic mark-up and uses vocabular to encode data. Search engines love this method of communicating metadata and use this to get additional information from web pages. The specification creates a “richer” experience for web users via rich snippets. Microdata often uses visual markup to style actual elements on the page it is time consuming.

Itemscope – specifies that the content within the specified div is an item.
Itemtype – describes what the item is within that scope.
Itemprop – describes each property of the specific item, example ‘name’. Each information type has properties that can be used to describe items in detail.

 JSON-LD : JSON deployment continues to grow at a faster pace. Json-LD schema are being widely accepted because of ease of implementation. JSON-LD helps markup data context through the use of types and properties. This is simple as it uses inline script tags instead of adding attributes for properties to existing HTML. JSON-LD is "a JSON-based format to serialize Linked Data.".

Initially, Google started recognising Microdata only but now JSON-LD is preferred over all other schema.

Json-LD gives a clear advantage over competitors if it is well-implemented and recognized by search engines. JSON-LD is “preferred” version of schema and hence more easily picked up.

JSON-LD Vs Microdata: Similarities and Differences

JSON injects metadata in the head section.
Microdata markup is added inline, where the HTML is present by pairing name-value.
This is used as a data block added as a script element. No need to tweak actual HTML data.
This is added inline to existing HTML.
Json-LD works with all types of media content. It is used for APIs and web pages both. Popular for media files – video, music, images.
Is an HTML 5 specification; supports only HTML documents.
Loads faster, better indexing in search engines, no need to alter HTML.
Takes time compared to JSON-LD; as it uses markup to style existing HTML and CSS. Also, results in messing the HTML.
Suitable for small to medium size pages and media files.
For too many pages with a similar template or a page with too many items to markup this is more suitable. Example: Product based, reviews.
Json schema generator are available to generate Json code and tester tools can be used to validate the script generated
To generate your own code, you can use Google's Structured Data Markup Helper.

Interesting Case Studies Of Successful Implementation of Schema Examples

A few other snippets that power Google search results apart from Knowledge graph, structured data are:

Featured Snippets

Other type of snippet is featured snippet. The featured snippet is the first result displayed in the top left in SERP to answer your question. Featured snippets are considered as a part of SERP feature. Google picks content from your webpage as the best match to a user query. This has higher CTR than normal organic results. There are three types of snippets, depending on the query: Paragraph, List, Table

Featured snippets are highly authoritative as picked by Google as the best match for a user query, rank number 1 and increase CTR of the page and so traffic increases by 20-25%. Here also, schema implementation would help.
