Beginner SEO interview questions
1. What is SEO?
SEO (Search Engine Optimization) is the practice of improving a website so it ranks higher in organic search results and earns more relevant, unpaid traffic.
2. What is the difference between organic and paid results?
Organic results are earned through relevance and authority and are free per click; paid results are ads you pay for per click or impression.
3. What are keywords?
Keywords are the words and phrases people type into search engines. SEOs target them to match content with user intent.
4. What is on-page SEO?
On-page SEO is optimising elements on the page itself: title, meta description, headings, content, internal links, images and schema.
5. What is off-page SEO?
Off-page SEO is work done outside your site to build authority, mainly backlinks, brand mentions and digital PR.
6. What is a meta title and meta description?
The meta title is the clickable headline in search results; the meta description is the short summary below it. Both influence click-through rate.
7. What is a backlink?
A backlink is a link from another website to yours. Quality backlinks act as votes of trust and improve rankings.
8. What are header tags (H1-H6)?
Header tags structure content hierarchically. The H1 is the main heading; H2-H6 organise sections and help both users and crawlers.
9. What is alt text?
Alt text describes an image for screen readers and search engines, helping accessibility and image SEO.
10. What is a SERP?
SERP means Search Engine Results Page, the page of results returned for a query, including organic listings, ads and features like snippets.
11. What is anchor text?
Anchor text is the clickable, visible text of a link. Descriptive, relevant anchor text helps search engines understand the linked page.
12. What is a keyword's search intent?
Search intent is the goal behind a query, usually informational, navigational, commercial or transactional. Content must match it to rank.
13. What is indexing?
Indexing is when a search engine stores and organises a page so it can appear in results. A page must be crawled and indexed to rank.
Intermediate SEO interview questions
14. What is technical SEO?
Technical SEO optimises crawlability, indexation, site speed, mobile-friendliness, structured data and site architecture so search engines can access and understand a site.
15. What is a canonical tag?
A canonical tag tells search engines the preferred version of a page when duplicates exist, consolidating ranking signals.
16. What is a robots.txt file?
robots.txt instructs crawlers which URLs they may or may not crawl. It controls crawling, not indexing.
17. What is an XML sitemap?
An XML sitemap lists a site's important URLs to help search engines discover and crawl them efficiently.
18. What is the difference between noindex and nofollow?
Noindex keeps a page out of the index; nofollow tells engines not to pass link equity through a link.
19. What are Core Web Vitals?
Core Web Vitals are Google's user-experience metrics: LCP (loading), INP (interactivity, which replaced FID), and CLS (visual stability).
20. What is crawl budget?
Crawl budget is the number of pages a search engine will crawl on your site in a given period. It matters most for large sites.
21. What is duplicate content and why is it a problem?
Duplicate content is identical or very similar content on multiple URLs. It can split ranking signals and confuse search engines about which page to rank.
22. What is internal linking and why does it matter?
Internal linking connects pages within a site, spreading authority, aiding crawling and helping users and engines understand structure.
23. What is E-E-A-T?
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness, quality signals Google uses to assess content, especially in YMYL topics.
24. What is a 301 vs 302 redirect?
A 301 is a permanent redirect that passes ranking signals; a 302 is temporary and is used when the move is not permanent.
25. What is schema markup?
Schema markup is structured data (usually JSON-LD) that helps search engines understand content and can enable rich results.
26. How do you do keyword research?
Start with seed topics, expand with tools, analyse volume, difficulty and intent, study competitors, then map keywords to pages.
27. What is a featured snippet?
A featured snippet is a highlighted answer box at the top of some SERPs. You win it with clear, concise answers to specific questions.
28. How do you measure SEO success?
Through organic traffic, keyword rankings, impressions and clicks in Search Console, conversions, and revenue, not vanity metrics alone.
Advanced SEO interview questions
29. How do you conduct a technical SEO audit?
Crawl the site, check indexation, review Core Web Vitals, fix crawl errors, audit redirects, canonicals, schema, internal links and mobile usability, then prioritise fixes by impact.
30. How do you recover from a Google algorithm update?
Diagnose whether it is a core, spam or helpful-content update, audit affected pages, improve content quality and E-E-A-T, remove or improve thin pages, and give it time to reassess.
31. What is log file analysis used for?
Log file analysis shows how search engine bots actually crawl your site, revealing crawl waste, ignored pages and crawl-budget issues.
32. How do you handle international SEO?
Use hreflang tags, correct URL structures (subdirectories, subdomains or ccTLDs), localised content and consistent signals per region and language.
33. What is entity SEO?
Entity SEO optimises around clearly defined people, places, brands and concepts using consistent data and schema so search engines understand relationships, not just keywords.
34. What is GEO (Generative Engine Optimization)?
GEO optimises content to be cited by AI engines like AI Overviews, ChatGPT and Perplexity, using clear answers, structured data, consistent entities and trusted mentions.
35. How is AI-SEO different from traditional SEO?
Traditional SEO targets ranked links; AI-SEO also optimises for passage-level citation in AI answers, focusing on clarity, authority and machine-readable structure.
36. How do you build high-quality backlinks in 2026?
Through digital PR, original data, guest expertise, useful tools and genuinely link-worthy content, never bought or spammy links that risk penalties.
37. How do you scale SEO with programmatic pages without thin content?
Use unique, valuable data per page, strong templates, internal linking, and index only pages that genuinely serve intent, avoiding index bloat.
38. What is cannibalization and how do you fix it?
Keyword cannibalization is when multiple pages compete for the same query. Fix it by consolidating, redirecting, or differentiating intent and internal links.
39. How do you optimise Core Web Vitals in practice?
Improve LCP with faster servers, optimised images and critical CSS; improve INP by reducing JavaScript work; improve CLS by reserving space for media and ads.
40. How do you prioritise SEO tasks with limited resources?
Rank tasks by potential impact versus effort, focus on high-intent pages and quick technical wins first, and align with business revenue goals.
