What is SEO?
SEO stands for Search Engine Optimization—a digital strategy that improves your website’s visibility in organic (non-paid) search results on platforms like Google and Bing.
When people search for products, services, or answers online, search engines try to show the most relevant and trustworthy results first. SEO helps you earn a spot on that first page—ideally in the top few positions.
SEO isn’t about tricking the algorithm. It’s about building a site that genuinely deserves to rank higher, based on three core principles:
- Technical performance
- Content relevance
- Website authority
Why Is SEO Important?
- It Drives Free, Long-Term Traffic – Rank for valuable keywords and attract visitors 24/7—without paying per click.
- It Builds Trust and Credibility – Appearing in top results increases user confidence in your brand.
- It Enhances User Experience – Fast loading, mobile-friendliness, and clear structure benefit both users and search engines.
- It Supports Other Channels – Search data improves paid campaigns, content strategies, and product planning.
- It’s Sustainable and Scalable – SEO continues delivering traffic even when ad budgets pause.

Structured Data and Rich Results
Structured data is a standardized format for providing information about a page and classifying its content. It uses schema.org markup (usually in JSON-LD format) to help search engines better understand what’s on a page.
When implemented correctly, structured data can unlock rich results—enhanced listings in search results with visual or interactive elements like:
- Star ratings and review snippets
- FAQs and dropdowns
- Product prices and availability
- Breadcrumbs
- Event and recipe cards
Adding structured data does not guarantee rich results, but it increases the likelihood and helps search engines interpret your content more precisely.
Recommended Testing Tools
- Rich Results Test – Check if your structured data qualifies for enhanced search features.
- Schema Markup Validator – Validate the structure and syntax of your schema code.
To implement structured data, most websites use <script type="application/ld+json"> tags in the page head or body. Platforms like WordPress often support it through SEO plugins like Rank Math, Yoast, or via custom code in templates.
Tip: Start by adding structured data to your homepage, product pages, blog articles, and FAQ sections to enhance visibility and click-through rates.
