1. Can You Explain What SEO Is and Why It Matters?

Why They Ask: A baseline question to confirm you understand SEO’s core purpose.

2. What’s the Difference Between On-Page and Off-Page SEO?

Why They Ask: They’re checking your SEO fundamentals.

3. How Do You Conduct Keyword Research?

Why They Ask: Keyword research underpins a solid SEO strategy.

What to Say: Mention tools like Google Keyword Planner or SEMrush, then emphasize analyzing search intent, difficulty, and competitiveness. George recommends highlighting how you identify “low-hanging fruit” keywords that drive conversions, not just traffic.

Why They Ask: Technical know-how is critical.

What to Say: Reference tools like Screaming Frog or Sitebulb to identify crawling, indexing, and page speed issues. Highlight a systematic approach—prioritizing critical fixes first. “Efficiency and process matter. Show you can manage a project, not just spot errors,” George advises.

6. What’s Your Take on Link Building vs. Content Marketing?

Why They Ask: They want to see if you understand the synergy between great content and authoritative links.

What to Say: Stress that valuable, well-produced content naturally attracts links. Then discuss strategic outreach and relationship-building. George notes, “The best responses frame link building as a logical extension of a strong content strategy, not a shortcut.”

7. Can You Explain the Importance of Mobile-First Indexing?

Why They Ask: Mobile is no longer optional.

What to Say: Illustrate how Google now primarily uses the mobile version of pages for indexing and ranking. Emphasize responsive design, fast load times, and mobile-friendly navigation. George suggests pointing to real metrics, like improved mobile conversions, to strengthen your case.

8. How Do You Measure the Success of an SEO Campaign?

Why They Ask: Businesses want to see clear ROI.

What to Say: Reference metrics like organic traffic growth, ranking improvements, and conversions—tied to overall business goals. “Analytics fluency is huge,” says George. “Show that you track outcomes with tools like Google Analytics and communicate results clearly to stakeholders.”

Why They Ask: They’re gauging your technical depth and forward-thinking approach.

10. Tell Us About Your Experience with Local SEO

Why They Ask: If local presence matters, they want local SEO pros.

13. How Do You Handle Negative SEO or a Sudden Drop in Rankings?

Why They Ask: Problem-solving skills are vital.

What to Say: Walk through a logical diagnostic process: Check Google Search Console, analyze backlink profiles, review recent changes. “Calm, data-driven trouble-shooting will impress employers,” George says. “Show you can keep your cool and communicate transparently.”

14. Explain the Importance of Content Quality vs. Quantity

Why They Ask: Quality trumps volume in modern SEO.

What to Say: Stress that well-researched, authoritative content beats a flood of thin articles. George notes, “Hiring managers want to know you’ll protect their brand’s reputation and authority, not just churn out content.”

15. How Do You Approach E-A-T (Expertise, Authoritativeness, Trustworthiness)?

Why They Ask: They want to see if you understand Google’s quality guidelines.

What to Say: Emphasize authoritative content, reputable sources, expert authorship, and maintaining user trust. “Highlight tactics like citing credible references and featuring subject matter experts,” George says.
