An SEO campaign is a planned set of search optimisation work, with a clear goal, target pages and keywords, a timeline and success metrics, aimed at growing organic traffic or leads. It usually combines technical fixes, content and link building. Expect a version of this in almost every list of SEO interview questions.
Key takeaways
- Most SEO interview questions test three things: whether you understand how search works, whether you can diagnose problems, and whether you can explain your reasoning.
- Beginner and SEO executive interview questions focus on definitions. Senior interviews lean on scenarios and trade-offs.
- A technical SEO interview will cover crawling, indexing, rendering, redirects and Core Web Vitals in depth.
- In 2026, expect at least a few questions on AI Overviews, GEO and how you'd measure AI search visibility.
I've grouped the 50 questions by level. The answers are short on purpose: use them as a base, then add an example from your own work. Interviewers remember the example, not the definition.
Beginner SEO interview questions (1–15)
These come up in fresher and SEO executive interview questions. Answer them clearly and briefly.
1. What is SEO?
Search engine optimisation is the work of improving a website so it appears for relevant searches and earns organic (unpaid) traffic. It covers technical health, content and authority, and in 2026 also visibility in AI answers.
2. How do search engines work?
They crawl pages by following links and sitemaps, index the content they judge useful, then rank indexed pages for each query based on relevance, quality and many other signals.
3. What is on-page SEO?
Optimising elements on the page itself: content, title tag, headings, internal links, images, URL and structured data, so the page clearly matches the search intent it targets.
4. What is off-page SEO?
Signals that happen away from your site, mainly backlinks, but also brand mentions, reviews and your reputation across the web.
5. What is technical SEO?
Making sure search engines can crawl, render and index your site efficiently: site speed, mobile-friendliness, status codes, redirects, canonicals, sitemaps, robots.txt and structured data.
6. What's the difference between short-tail and long-tail keywords?
Short-tail keywords are broad (e.g. "running shoes"), high volume and competitive. Long-tail keywords are longer and more specific ("best running shoes for flat feet"), with less volume, clearer intent and usually better conversion.
7. What is search intent?
The goal behind a query. The common types are informational (learn), navigational (find a specific site), commercial (compare options) and transactional (buy or sign up). A page that doesn't match intent struggles to rank.
8. What are title tags and meta descriptions?
The title tag is the page's HTML title, often shown as the clickable headline in results. The meta description is a summary that may appear as the snippet. Google can rewrite both. More in my guide to title tags.
9. What is a backlink?
A link from another website to yours. Relevant, editorial backlinks from trusted sites are one of the strongest signals of authority.
10. What's the difference between dofollow and nofollow links?
A normal ("dofollow") link can pass ranking credit. Links marked rel="nofollow", rel="sponsored" or rel="ugc" tell Google the link is unendorsed, paid or user-generated. Google treats these as hints and usually doesn't pass credit through them.
11. What is anchor text?
The clickable text of a link. It helps search engines understand the linked page. Natural anchors vary; lots of exact-match keyword anchors can look manipulative.
12. What is a SERP?
The search engine results page. It includes organic results plus features like AI Overviews, featured snippets, People Also Ask, local packs, images and videos.
13. What is Domain Authority?
A third-party score (Moz's DA, Ahrefs' DR and similar) estimating a site's link strength. Google doesn't use these scores. They're useful for comparing sites, not as a goal.
14. What is an XML sitemap?
A file listing the URLs you want search engines to find, often with last-modified dates. It helps discovery but doesn't guarantee indexing.
15. What is robots.txt?
A file at the root of a site that tells crawlers which paths they may request. It controls crawling, not indexing: a blocked URL can still be indexed if other pages link to it.
Intermediate SEO interview questions (16–30)
These test whether you've done the work, not just read about it.
16. What is E-E-A-T?
Experience, Expertise, Authoritativeness and Trustworthiness. It's a framework from Google's Search Quality Rater Guidelines for judging content quality. It isn't a single ranking factor, but it describes what Google's systems try to reward.
17. How do you do keyword research?
Start with seed topics from the business and customers, expand with tools and Search Console queries, group keywords by intent, check who ranks now, then prioritise by relevance, difficulty and business value.
18. What is keyword cannibalisation?
When several of your pages target the same intent and compete with each other. Fix it by merging pages and redirecting, or by clearly differentiating each page's target.
19. Why does internal linking matter?
It helps crawlers find pages, spreads authority across the site and shows which pages matter most. Use descriptive anchors and link from relevant, strong pages.
20. What is a canonical tag?
A rel="canonical" link that tells search engines which URL is the main version among duplicates. It's a strong hint, not a directive. I've covered the common Search Console issue in duplicate without user-selected canonical.
21. What's the difference between a 301 and a 302 redirect?
A 301 is permanent and tells Google to move signals to the new URL. A 302 is temporary. Use 301 for migrations and permanent URL changes.
22. What is a Google core update, and how do you respond to one?
A broad change to Google's ranking systems, released several times a year. Don't make panicked changes mid-rollout. Wait for it to finish, compare affected pages to winners and improve content quality. See my Google core updates guide.
23. How do you measure SEO success?
Tie metrics to business goals: organic conversions and revenue first, then clicks, impressions, rankings for priority keywords, indexed pages and AI visibility. I list the ones worth tracking in SEO KPIs.
24. What is local SEO?
Optimising for location-based searches: a complete Google Business Profile, consistent name, address and phone details, reviews, local landing pages and local links.
25. What is structured data?
Code (usually JSON-LD using schema.org) that describes a page's content to search engines. It can make pages eligible for rich results. Google has retired some rich results, including FAQ rich results in 2026, so check the current list before promising any.
26. How do you run a content audit?
Export all indexable URLs with traffic, conversions, links and indexing status. Decide for each: keep, update, merge, redirect or remove. Prioritise pages with impressions but falling clicks.
27. How do you build links?
Create linkable assets (tools, data, strong guides), then earn links through digital PR, journalist requests, partnerships, guest posts on relevant sites and broken link outreach. Never buy links that pass PageRank. More in how to get backlinks.
28. What is a topic cluster?
A pillar page covering a broad topic, linked to and from supporting pages on subtopics. It organises content and internal links around a theme.
29. What's the difference between Search Console and GA4?
Search Console shows how Google sees your site: queries, impressions, clicks, indexing and technical issues. GA4 shows what users do once they arrive: sessions, engagement and conversions. You need both.
30. How do you target a featured snippet?
Find queries where one already appears and you rank on page one. Add a direct, concise answer under a matching heading, in the format Google shows (paragraph, list or table).
Technical SEO interview questions (31–40)
A technical SEO interview goes deeper. Expect follow-ups like "how would you check that?"
31. What are Core Web Vitals?
Google's user-experience metrics: Largest Contentful Paint (good at 2.5 seconds or less), Interaction to Next Paint (200 ms or less) and Cumulative Layout Shift (0.1 or less), measured at the 75th percentile of page loads. INP replaced FID in 2024. Source: web.dev.
32. What is crawl budget, and when does it matter?
How many URLs Google can and wants to crawl on your site. Google's crawl budget guide is aimed at large sites (roughly 1 million+ pages, or 10,000+ pages changing daily). For most small sites it isn't the issue.
33. What does "Crawled – currently not indexed" mean?
Google fetched the page but chose not to index it, usually because of quality, duplication or technical reliability. My crawled currently not indexed guide covers nine causes.
34. How does Google handle JavaScript?
It crawls the HTML, queues the page for rendering, runs the JavaScript and then indexes the rendered content. Problems come from blocked resources, content loaded only after interaction, and links without real href attributes.
35. What is hreflang?
An annotation that tells Google which language or regional version of a page to show to which users. Each version must reference the others and itself, with correct language-region codes.
36. What's the difference between noindex and a robots.txt disallow?
Noindex lets Google crawl the page but keeps it out of the index. Disallow stops crawling, so Google can't see a noindex tag on that page. To remove a page from results, allow crawling and use noindex.
37. What is mobile-first indexing?
Google mainly uses the mobile version of a page for indexing and ranking. The mobile version needs the same content, structured data and metadata as desktop.
38. How do you find and fix redirect chains and broken links?
Crawl the site with a tool like Screaming Frog, filter for 3xx chains and 4xx responses, then update internal links to point straight to the final URL and redirect removed pages that have links or traffic.
39. What is log file analysis?
Reviewing server logs to see exactly which URLs search engine bots request, how often and with what response. It shows crawl waste, errors and pages bots ignore.
40. What is a soft 404?
A page that returns a 200 status but looks like an error or empty page to Google. Fix it by returning a real 404/410 or adding real content. More in my soft 404 guide.
AI search and GEO interview questions (41–45)
These are new in the last two years, and many candidates aren't ready for them.
41. How do pages get cited in Google's AI Overviews?
Google's AI features documentation says there are no additional requirements beyond normal SEO. Pages need to be indexed and eligible for snippets, and clear, well-sourced passages that answer sub-questions tend to get cited. See how to rank in AI Overviews.
42. What is GEO, and how is it different from SEO?
Generative engine optimisation means improving your chances of being cited or mentioned in AI answers. It builds on SEO fundamentals but adds new measurement and a focus on passages and brand mentions. I compare them in GEO vs SEO.
43. Does llms.txt help rankings?
Not in Google. Google's 2026 AI optimisation guide says Google Search doesn't use llms.txt. Some other AI tools may read it, so it's low-cost but low-priority. Background in my llms.txt explainer.
44. How would you measure AI search visibility?
Use Search Console's Generative AI performance report for AI Overviews and AI Mode impressions, Bing Webmaster Tools' AI Performance report for Copilot, and a tracked set of prompts in ChatGPT and Perplexity, manually or with a visibility tool.
45. How can a site limit how its content appears in AI features?
In Google, use nosnippet, data-nosnippet, max-snippet or noindex. Search Console also added a site-level control for Google's generative AI Search features in 2026. For other AI tools, manage each crawler (like OAI-SearchBot) in robots.txt.
Scenario-based SEO interview questions (46–50)
Job seekers on r/SEO keep saying the same thing: interviewers care more about practical tasks than definitions. These are the questions that separate candidates. Talk through your thinking, step by step.
46. Organic traffic dropped 40% overnight. What do you check first?
Confirm it's real (tracking changes, GA4 vs Search Console). Check whether it's site-wide or specific pages, then check for a known Google update, manual actions, robots.txt or noindex changes, redirects, server errors and recent deployments.
47. A client wants to rank first for a very competitive keyword in three months. What do you say?
I'd show them who ranks now, what those pages have (links, depth, brand strength) and a realistic timeline. Then I'd propose long-tail keywords that can win sooner while the main page builds authority.
48. We're migrating to a new domain next month. What's your plan?
Crawl and benchmark the old site, map every URL to its new equivalent with 301s, keep content and metadata, test on staging, launch, submit the new sitemap, use Search Console's Change of Address tool, and monitor indexing and traffic daily.
49. A new site has 200 pages but only 30 are indexed. What do you do?
Check the Page indexing report for the reasons. Fix technical blocks first, then look for thin or duplicate pages to merge, strengthen internal links to key pages, and build a few quality links. Don't mass-request indexing.
50. You get 10 hours a month for a small local business. How do you spend them?
Start with Google Business Profile, reviews and fixing major technical issues. Then spend most hours on one or two high-intent service pages and local links. Report monthly on calls, forms and local rankings.
What interviewers look for, and how to prepare
Here's what interviewers are usually looking for at each level. Salary and seniority also shape which questions you'll get; my SEO salary guide breaks down pay by level.
| Level | Typical title | What interviewers test | Example task |
|---|---|---|---|
| Entry | SEO executive, SEO trainee | Definitions, tools, basic on-page | Write a title and meta description for a page |
| Mid | SEO specialist, SEO analyst | Keyword research, audits, reporting | Audit one page and list the top five fixes |
| Technical | Technical SEO specialist | Crawling, rendering, redirects, logs | Diagnose indexing issues from a crawl export |
| Senior | SEO lead, SEO manager | Strategy, prioritisation, stakeholders | Build a six-month plan for a given budget |
How to prepare in a week:
- Study the company's site. Run a quick audit: indexing, titles, speed, internal links. Note three specific problems.
- Check their search results. Search their main keywords and see who outranks them and why.
- Prepare two stories from your own work. One win and one failure, each with the problem, what you did and the result in numbers.
- Revise the fundamentals. Crawling, indexing, canonicals, redirects, Core Web Vitals and intent. My Learn SEO guide is a free refresher.
- Practise scenario answers out loud. Use questions 46 to 50. Structure: clarify, diagnose, prioritise, act, measure.
- Know the tools. Be ready to show Search Console, GA4 and one crawler. Many interviews include a live screen-share.
- Prepare questions for them. Ask how SEO success is measured, who owns content and dev work, and what's blocked SEO in the past.
The most common weak spot is reciting definitions without examples. If you say "internal linking helps", follow it with something like "on my last site I added links from our top five pages to a new guide, and here's what happened", using your real numbers.

Frequently asked questions
What is an SEO campaign?
An SEO campaign is a focused project to improve organic search results for a specific goal, such as ranking a product category or growing blog leads. It defines target keywords and pages, the technical, content and link work needed, a timeline, and the metrics used to judge success.
What is off site SEO?
Off-site (off-page) SEO covers actions outside your website that build its authority and reputation. The main part is earning backlinks from relevant sites. It also includes brand mentions, digital PR, reviews and a consistent presence on platforms your audience uses.
What is on page optimization?
On-page optimisation means improving elements on a web page so it ranks for its target queries and serves users well. That includes the content itself, title tag, headings, URL, internal links, image alt text, structured data and how well the page matches search intent.
What does an SEO executive do?
An SEO executive handles day-to-day SEO tasks: keyword research, on-page updates, content briefs, basic technical checks, link outreach and reporting. It's usually an entry or junior role reporting to an SEO manager or lead.
How do I prepare for a technical SEO interview?
Revise crawling, indexing, rendering, canonicals, redirects, hreflang, robots directives and Core Web Vitals. Practise diagnosing issues in Search Console and a crawler like Screaming Frog. Be ready to explain how you'd check each problem, not just what it is.
