what is schema markup & how does it work

A schema markup is a type of structured data vocabulary created by schema.org, which enables webmasters to tag content with standardized terms. However, these types of tags will help search engines to interpret the data & serve it in a meaningful way to the search results. 

However, a schema markup works by simply embedding a script in your webpage’s HTML. For instance: 

“`json

<script type=”application/ld+json”>

{

  “@context”: “https://schema.org”,

  “@type”: “Product”,

  “name”: “Smartphone XYZ”,

  “brand”: “TechBrand”,

  “offers”: {

    “@type”: “Offer”,

    “price”: “499.99”,

    “priceCurrency”: “USD”

  }

}

</script>

“`

This script clearly indicates to the search engines that this page is about product, its name, brand as well as price.
