Frequently Asked Questions

What does SEO fundamentals include?

SEO fundamentals covers four core areas: a quality assessment framework (E-E-A-T), page experience metrics (Core Web Vitals), technical accessibility (crawl, index, performance), and content quality principles (depth, originality, accuracy, clarity, and usefulness). These fundamentals ensure your site is search-engine friendly while also providing genuinely valuable content for users.

How does the E-E-A-T framework affect website rankings?

E-E-A-T is not a direct ranking factor. Instead, it is a framework search engines use to assess content quality. Experience is demonstrated through firsthand examples and demonstrations. Expertise is shown through credentials, depth, and accuracy. Authoritativeness is reflected through citations, mentions, and links. Trustworthiness is demonstrated through HTTPS, transparency, and accuracy. In highly competitive fields, websites often differentiate through trust and experience.

Can structured data directly improve rankings?

No. Structured data (Schema) primarily helps search engines understand the meaning of content, rather than directly improving rankings. It can make your pages eligible for rich results, but it doesn’t guarantee you’ll get them. Common Schema types include Article, Organization, Person, FAQPage, Product, Review, and BreadcrumbList, and each has its specific purpose.
