SEO Interview Questions & Answers

The answers are written in a professional, interview-ready style, with emphasis on SEO, AEO, GEO, AI search, technical SEO, analytics, and strategy.

1. How do you approach keyword research?

Answer:
I start by understanding the business goals, target audience, products/services, and competitors. I use tools such as Ahrefs, Semrush, SE Ranking, or Similarweb to identify relevant keywords based on search volume, competition, search intent, and business value. I then group keywords into topical clusters and map them to the appropriate pages to avoid keyword cannibalisation and build topical authority.

2. What is search intent, and why is it important?

Answer:
Search intent is the reason behind a user's search query. I generally classify it as informational, navigational, commercial, or transactional. Understanding intent helps me create content that matches what users and search engines expect. For example, a "best abacus classes" query may require comparison or commercial content, while "how does an abacus work" needs informational content.

3. What is topical clustering?

Answer:
Topical clustering is the process of organising related keywords and content around a central topic. I create a pillar page for the main topic and supporting cluster pages for related subtopics, connecting them through internal links. This helps establish topical relevance and creates a logical content structure for both users and search engines.

4. How do you optimise a webpage for SEO?

Answer:
I optimise the title tag, meta description, H1 and other headings, URL, content structure, keyword relevance, internal links, images, schema markup, and overall content depth. I also make sure the page satisfies search intent and provides genuinely useful information rather than simply inserting keywords.

5. How do you perform a technical SEO audit?

Answer:
I begin with a crawl using tools such as Screaming Frog or Sitebulb. I check crawlability, indexation, status codes, redirects, canonical tags, robots.txt, XML sitemaps, duplicate content, internal linking, JavaScript rendering, page speed, Core Web Vitals, and site architecture. I then prioritise issues according to their SEO impact, implementation effort, and business importance.

6. How do you prioritise SEO issues?

Answer:
I use an effort-versus-impact framework. High-impact and relatively easy fixes are prioritised first. For example, fixing an accidentally blocked important page may take priority over a minor metadata issue. I typically classify recommendations as critical, high, medium, or low priority and provide clear implementation instructions to developers and content teams.

7. What is the difference between crawling, rendering, and indexing?

Answer:
Crawling is when a search engine discovers and accesses URLs. Rendering is when it processes the page, including JavaScript-generated content. Indexing is when the search engine stores and considers the page for its search index. A page can be crawlable but still have rendering or indexing problems, so I check each stage separately during technical audits.

8. What are canonical tags?

Answer:
A canonical tag tells search engines which version of a page should be treated as the preferred URL when multiple URLs have similar or duplicate content. I check that canonical tags are correctly implemented, self-referencing where appropriate, and not pointing to irrelevant, redirected, or non-indexable URLs.

9. How do you handle robots.txt and XML sitemaps?

Answer:
I use robots.txt to control crawler access to areas that shouldn't normally be crawled. I use XML sitemaps to help search engines discover important URLs. I regularly check that valuable indexable pages are included in the sitemap and that important pages aren't accidentally blocked through robots.txt or other directives.

10. What are Core Web Vitals?

Answer:
Core Web Vitals are Google's user-experience metrics focused on loading performance, responsiveness, and visual stability. The main metrics are LCP, INP, and CLS. I use Google Search Console and PageSpeed Insights to identify issues and work with developers to improve them.

AEO, GEO & AI Search

11. What is AEO?

Answer:
AEO stands for Answer Engine Optimisation. It focuses on structuring content so that answer engines can easily understand and extract useful answers. I use clear questions and answers, concise definitions, structured headings, lists, tables, and directly answerable content.

12. What is GEO in SEO?

Answer:
GEO, or Generative Engine Optimisation, focuses on improving a brand's visibility and representation in AI-generated search experiences. The strategy involves creating authoritative, well-structured and easily retrievable content, strengthening brand and entity signals, and increasing the likelihood that reliable sources are referenced by AI search systems.

13. How would you optimise content for Google AI Overviews?

Answer:
I would first satisfy the underlying search intent with high-quality content. Then I would structure important information using clear headings, concise answers, definitions, comparisons, lists, FAQs, supporting evidence, and relevant structured data. I would also strengthen the site's authority and entity signals rather than relying on keyword optimisation alone.

14. How do you structure content for LLM retrieval?

Answer:
I make important information easy to identify and extract. I use descriptive headings, short Q&A sections, clear definitions, comparison tables, factual claims supported by credible sources, concise summaries, and logical internal linking. I avoid burying important information inside unnecessarily complicated paragraphs.

15. What is Entity SEO?

Answer:
Entity SEO focuses on helping search engines and AI systems understand who or what a brand, organisation, product, or person is and how it relates to other entities. I focus on consistent brand information across authoritative websites, structured data, relevant mentions, organisation profiles, and other trustworthy signals.

16. How can schema markup help SEO?

Answer:
Schema markup provides structured information about a webpage to search engines. Depending on the content, I may implement schemas such as Organization, Article, Product, Breadcrumb, Review, FAQ, or HowTo where supported and appropriate. I always validate the implementation and make sure the structured data accurately represents visible page content.

17. How would you track a brand's visibility in AI search?

Answer:
I would establish a set of representative prompts and queries related to the brand, products, services, and competitors. I would then monitor brand mentions, citations, referenced URLs, positioning, and changes over time using appropriate AI visibility tools and manual checks across relevant AI search platforms.

18. What is your approach to AI crawler access and emerging standards such as llms.txt?

Answer:
I would evaluate each emerging standard based on its actual adoption, documented purpose, technical implications, and potential business value rather than implementing it simply because it is trending. I would also review AI crawler access policies and content licensing considerations with the relevant technical and legal stakeholders.

Off-Page & Local SEO

19. What is your approach to link building?

Answer:
I focus on earning relevant and authoritative links through digital PR, useful research, expert contributions, genuine guest placements, partnerships, and unlinked brand mentions. I prioritise relevance and editorial value rather than simply trying to increase the number of backlinks.

20. What would you do with an unlinked brand mention?

Answer:
I would identify the website owner or author and assess whether the mention is relevant and valuable. If appropriate, I would conduct personalised outreach requesting that the brand mention be linked to a relevant authoritative page.

21. When would you consider disavowing backlinks?

Answer:
I wouldn't disavow links simply because they appear low quality. First, I would assess the backlink profile, identify patterns of manipulative or harmful links, and determine whether there is a genuine need for action. Any disavow decision should be evidence-based and carefully considered.

22. What is your approach to Local SEO?

Answer:
I focus on Google Business Profile optimisation, consistent business information across relevant citations, location-specific landing pages, reviews, local relevance, internal linking, and appropriate structured data. I also monitor local rankings, visibility, calls, enquiries, and other relevant conversions.

Analytics & Reporting

23. How do you use Google Search Console?

Answer:
I use GSC to analyse queries, impressions, clicks, CTR, average position, indexing, sitemap status, page performance, and technical issues. I segment data by page, query, device, country, and other available dimensions to identify opportunities and diagnose traffic changes.

24. How do you use GA4 for SEO?

Answer:
I use GA4 to understand what happens after organic users arrive on the website. I analyse organic sessions, landing pages, engagement, conversions, user journeys, and revenue or leads where tracking is available. This helps connect SEO performance with actual business outcomes rather than focusing only on rankings.

25. What SEO metrics would you report every month?

Answer:
I would typically report:

Organic sessions
Qualified organic traffic
Search impressions
Clicks and CTR
Keyword visibility
Rankings for priority clusters
Organic leads/conversions
Revenue where applicable
Technical SEO health
AI visibility and citation/mention share
Key wins and losses
Completed SEO work
Next month's priorities

The report should explain what changed, why it changed, and what we are doing next, rather than simply presenting charts.

26. How would you investigate a sudden drop in organic traffic?

Answer:
I would first establish when the decline started and which pages, queries, countries, and devices were affected. Then I would check Google Search Console, GA4, technical changes, indexing, robots.txt, server errors, redirects, canonicalisation, algorithm updates, SERP changes, seasonality, and competitor activity. I would compare the affected period with previous periods to identify the likely cause before recommending fixes.

Practical & Strategic Questions

27. Which SEO tools have you worked with?

Answer:
I have experience with SEO tools such as Ahrefs, Semrush, Screaming Frog, Google Search Console, Google Analytics 4, and Looker Studio. I use these tools for different purposes—for example, keyword and backlink research in Ahrefs/Semrush, technical crawling in Screaming Frog, performance analysis in GSC and GA4, and reporting through Looker Studio.

28. How do you work with developers and content teams?

Answer:
I translate SEO recommendations into clear, actionable tasks. For developers, I provide the issue, affected URLs, SEO impact, recommended implementation, and acceptance criteria. For content teams, I provide search intent, keyword clusters, content structure, internal-linking recommendations, and optimisation guidance. I also follow up after implementation to verify that fixes actually shipped correctly.

29. How would you demonstrate that your SEO work produced results?

Answer:
I would establish a baseline before making significant changes and then track measurable outcomes. Depending on the project, these could include organic traffic, qualified sessions, keyword visibility, impressions, CTR, leads, conversions, revenue, technical health, and AI visibility. I prefer reporting the actual numbers and timeframe rather than making vague claims about improvement.

30. Why should SEO reporting focus on business outcomes rather than rankings alone?

Answer:
Rankings are useful diagnostic metrics, but they don't necessarily represent business success. A keyword can rank highly without generating valuable traffic or conversions. I therefore connect SEO activity to qualified traffic, leads, conversions, revenue, and visibility in relevant search experiences.

Scenario-Based Interview Questions

31. A page has high impressions but a very low CTR. What would you do?

Answer:
I would review the queries generating impressions and compare the page's search intent with the title and meta description. I would test whether the title clearly communicates the value of the page and accurately matches the query. I would also examine SERP features and competing results before making changes.

32. A page ranks on page two for an important keyword. How would you improve it?

Answer:
I would analyse the current SERP, search intent, competing pages, content gaps, topical coverage, internal links, backlinks, technical factors, and overall page quality. Then I would create a prioritised optimisation plan rather than simply adding more keywords.

33. A website has thousands of pages but only a small percentage are indexed. What would you investigate?

Answer:
I would examine crawlability, indexation directives, sitemap quality, canonicalisation, duplicate or thin content, internal linking, site architecture, crawl budget considerations, server responses, JavaScript rendering, and whether the pages provide sufficient unique value to warrant indexing.

34. How would you create an SEO strategy for a new website?

Answer:
I would start with business and audience research, followed by competitor analysis and keyword research. Then I would build topical clusters and the site's information architecture, establish technical SEO foundations, create a content roadmap, implement on-page and structured-data optimisation, develop an authority strategy, configure analytics, and establish KPIs. I would then prioritise initiatives based on expected impact and effort.

35. What would your first 90 days in this SEO role look like?

Answer:
First 30 days: Understand the business, website, analytics, competitors, existing SEO strategy, technical health, keyword landscape, and current AI visibility.

Days 31–60: Complete the technical and content audits, develop keyword/topic clusters, prioritise fixes, improve important pages, and establish reporting.

Days 61–90: Execute the highest-impact technical and content initiatives, develop the off-page and AI visibility strategy, measure early results, and create a longer-term SEO roadmap.

The exact priorities would depend on the site's current condition and business objectives.
