Below is a comprehensive set of beginner-friendly SEO questions likely to appear in job interviews, along with professional yet easy-to-understand answers.

A. On-Page SEO Interview Questions

1. What is SEO?

Answer:

SEO (Search Engine Optimization) is the practice of improving a website’s visibility in organic search results. It involves optimizing site structure, content, user experience, and external signals to help search engines understand and rank pages more effectively.

2. What is On-Page SEO?

Answer:

On-Page SEO refers to optimizations made directly on a webpage, including meta tags, headings, keyword usage, URL structure, internal linking, image optimization, and ensuring content matches user search intent.

3. What is a Meta Title? Why is it important?

Answer:

A meta title (title tag) is the clickable headline shown in search engine results. It signals page relevance to search engines and influences click-through rates.

Best practices:

• Keep under 55–60 characters
• Include a primary keyword naturally
• Write human-friendly, compelling titles

4. What is a Meta Description?

Answer:

A meta description summarizes page content and appears under the title in search results. While it's not a direct ranking factor, it influences user engagement and CTR.

5. What are Header Tags (H1, H2, H3)?

Answer:

Header tags structure content hierarchically.

• H1: Main topic of the page
• H2: Major subtopics
• H3: Supporting points

They help both users and search engines understand content organization.

6. What is Keyword Density?

Answer:

Keyword density measures how frequently a target keyword appears relative to total text. Modern SEO discourages focusing heavily on density; instead, the goal is to satisfy search intent with natural language.
