What is schema markup and why does it matter for SEO?
Schema markup is structured data you add to your HTML that helps search engines understand your content. It can trigger rich results in Google — like FAQ dropdowns, star ratings, product prices, and knowledge panels. Pages with schema markup get up to 30% higher click-through rates than plain results.
What is JSON-LD and how do I add it to my website?
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for schema markup. You add it as a <script type="application/ld+json"> tag in your page's <head> section. It doesn't affect how your page looks — it only tells search engines what your content means.
Which schema types should I use for my SaaS website?
For a SaaS website, start with Organization schema on your homepage, SoftwareApplication schema on your product/pricing page, FAQ schema on your FAQ or features page, and Article schema on blog posts. These four cover the basics and can trigger rich results in Google search.
How do I test if my schema markup is valid?
Use Google's Rich Results Test (search.google.com/test/rich-results) to validate your markup. It shows whether your schema is valid and which rich result types it's eligible for. You can also use the Schema Markup Validator at validator.schema.org for detailed syntax checking.
Can schema markup hurt my SEO if done wrong?
Invalid or misleading schema won't directly hurt your rankings, but it can prevent rich results from appearing. Google may also issue manual actions for spammy structured data — like fake reviews or misleading product schema. Always use schema that accurately represents your page content.
