Schema markup is a form of structured data that you add to your website's HTML to help search engines understand your content more precisely. When implemented correctly, schema markup can earn your site rich results in Google — enhanced search listings with star ratings, prices, FAQs, event dates, and more. These rich results significantly increase click-through rates and visibility.
What Is Schema Markup?
Schema markup uses a standardized vocabulary maintained by Schema.org, a collaborative project by Google, Microsoft, Yahoo, and Yandex. It provides a common language for describing entities on the web — businesses, products, articles, events, people, and hundreds of other types.
There are three formats for implementing schema markup:
- JSON-LD (Recommended): A JavaScript-based format that sits in a
<script>tag. Google explicitly recommends this format because it is easy to add and maintain without modifying the visible HTML. - Microdata: HTML attributes added directly to your page elements. More complex to implement and maintain.
- RDFa: Similar to Microdata but uses different attribute names. Less commonly used for SEO purposes.
Schema Types Essential for Tanzanian Businesses
LocalBusiness Schema
If you operate a business with a physical location in Tanzania, LocalBusiness schema is critical. It tells Google your business name, address, phone number, hours, and more.
{
"@context": "https://schema.org",
"@type": "LocalBusiness",
"name": "Your Business Name",
"address": {
"@type": "PostalAddress",
"streetAddress": "123 Samora Avenue",
"addressLocality": "Dar es Salaam",
"addressRegion": "Dar es Salaam",
"addressCountry": "TZ"
},
"telephone": "+255-XXX-XXX-XXX",
"url": "https://yourbusiness.co.tz",
"openingHours": "Mo-Fr 08:00-17:00",
"priceRange": "$$"
}

Organization Schema
For companies that operate primarily online or have multiple locations, Organization schema establishes your brand identity in Google's Knowledge Graph.
Product Schema
E-commerce businesses should implement Product schema on every product page. This can generate rich results showing price, availability, and review ratings directly in search results.
FAQ Schema
Adding FAQPage schema to pages with frequently asked questions can display expandable Q&A directly in search results, dramatically increasing your listing's visual size.
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What hosting plans do you offer in Tanzania?",
"acceptedAnswer": {
"@type": "Answer",
"text": "We offer shared hosting, VPS, and dedicated server plans optimized for East African businesses."
}
}]
}
</script>

Measuring Schema Markup Impact

- Enhancement reports for each schema type (e.g., Products, FAQs, Local Business)
- Click-through rate changes for pages with schema versus those without
