SEO Interview Questions and Answers for Beginners and Freshers

Common SEO interview questions with clear, current answers: fundamentals, keyword research, on-page, technical, content, links, local SEO, Search Console and GA4, AI search, and scenario questions that test how you think.

Last reviewed: 14 October 2026

These SEO interview questions cover what entry-level and junior SEO interviews usually test: whether you understand the fundamentals and whether you can apply them. Use the answers to check your understanding, then say them in your own words with an example from your own practice work. Interviewers notice memorised answers quickly.

How to use this list

  • Read the question and answer it aloud before reading our answer.
  • Add one example from your own website or portfolio to each answer.
  • If you do not know something in an interview, say how you would find out. That is a good answer too.

SEO fundamentals

What is SEO?

SEO (search engine optimisation) is improving a website so that search engines can find, understand and show its pages for relevant searches, and so that people who arrive find what they need. It includes technical work, content and on-page optimisation, and earning mentions and links.

What is the difference between crawling, indexing and ranking?

Crawling is when a search engine’s bot fetches a page. Indexing is when the search engine processes the page and stores it so it can be shown. Ranking is choosing which indexed pages to show, and in what order, for a search. A page can be crawled but not indexed. More: how search engines crawl, index and rank.

What is the difference between SEO and SEM?

SEO earns unpaid (organic) visibility. SEM usually means paid search ads, such as Google Ads, although some people use it to mean both paid and organic search marketing.

What is E-E-A-T?

Experience, Expertise, Authoritativeness and Trustworthiness. It comes from Google’s guidance on helpful content and its quality rater guidelines. Google says E-E-A-T itself is not a specific ranking factor, but its systems aim to reward content that shows these qualities (see Google’s guide to creating helpful, reliable, people-first content).

Keyword research

How do you choose keywords for a new page?

I start from what the business offers and who its customers are, find the words people use with a keyword tool and Google’s own suggestions, check the search intent by looking at what currently ranks, and choose a main topic plus related questions that one page can genuinely answer.

What is search intent?

The goal behind a search: to learn something (informational), compare options (commercial), buy or sign up (transactional), find a specific site (navigational) or find something nearby (local). The page type must match the intent to have a chance of ranking. More: what is search intent?

What are long-tail keywords?

Longer, more specific searches such as “weekend SEO course for working professionals”. Each has fewer searches, but they are often easier to rank for and closer to a decision. More: long-tail vs short-tail keywords.

What is keyword cannibalisation?

When several pages on the same site target the same intent, so search engines are unsure which one to show. The fix is usually to combine the pages, redirect the weaker one, or clearly separate their topics.

On-page SEO

What makes a good title tag?

It describes the page accurately, puts the main topic near the start, is unique on the site and is short enough not to be cut off in most results. Google may rewrite titles that do not describe the page well.

Do meta descriptions affect rankings?

They are not a ranking factor, but a clear description can improve the click-through rate. Google often shows its own snippet from the page when that matches the search better. There is no fixed character limit.

Does Google use the meta keywords tag?

No. Google does not use the meta keywords tag for ranking.

Why are internal links important?

They help search engines discover pages and understand how they relate, and help visitors move to related content. Descriptive anchor text explains what the linked page is about. More: internal linking guide.

Technical SEO

What is the difference between robots.txt and a noindex tag?

robots.txt controls crawling, not indexing. A blocked URL can still appear in results if other pages link to it. To keep a page out of the index, use a noindex tag and let it be crawled, so search engines can see the tag.

What does a canonical tag do?

It tells search engines which URL you prefer when several URLs show the same or very similar content. It is a strong hint, not a command; Google may choose a different canonical if other signals disagree. More: canonical tags and duplicate URLs.

When should you use a 301 redirect?

When a page has moved permanently, for example after changing a URL or merging two pages. It sends visitors and search engines to the new URL and passes signals to it. Use a temporary redirect (302) only for temporary moves.

What are Core Web Vitals?

Three user-experience metrics: Largest Contentful Paint (loading, good at 2.5 seconds or less), Interaction to Next Paint (responsiveness, good at 200 milliseconds or less) and Cumulative Layout Shift (visual stability, good at 0.1 or less), measured at the 75th percentile of real visits. INP replaced First Input Delay in March 2024 (web.dev: Web Vitals). More: Core Web Vitals explained.

Does an XML sitemap guarantee indexing?

No. A sitemap helps search engines discover URLs, but each page still has to be crawlable, indexable and considered worth indexing.

What does structured data do?

It describes a page’s content in a standard format (schema.org) so search engines understand it better and the page can become eligible for rich results. It does not guarantee a rich result or a higher ranking.

Content SEO

How do you decide whether to update or create a page?

If an existing page already targets the intent, update and improve it. Create a new page only for a distinct intent that no page covers. Two similar pages usually compete with each other.

What is “helpful content”?

Content created mainly for people: it answers the question fully, shows real knowledge or experience, is accurate and up to date, and leaves the reader satisfied, rather than content written mainly to attract search traffic.

Links and off-page SEO

What is a good backlink?

A link from a relevant, trustworthy website that links because your content is genuinely useful. Relevance and trust matter far more than the number of links.

What do nofollow, sponsored and ugc mean?

They are rel attributes for links. Sponsored marks paid or advertising links, ugc marks user-generated content such as comments, and nofollow is for other links you do not want to vouch for. Google treats all three as hints, and such links generally do not pass ranking credit. More: dofollow vs nofollow backlinks.

Which link building tactics should you avoid?

Buying links that pass ranking credit, large-scale link exchanges, keyword-rich guest posts made at scale, and automated or low-quality directory links. Google’s spam policies treat these as link spam.

Local SEO

How does Google rank local results?

Mainly by relevance (how well the Business Profile matches the search), distance (how far the business is from the searcher or the searched location) and prominence (how well known it is, including reviews, links and articles). More: local SEO ranking factors.

How would you improve a Google Business Profile?

Complete every relevant field accurately, choose the right primary category, add real photos, keep hours up to date, ask satisfied customers for honest reviews and reply to them, and keep the name, address and phone number consistent everywhere.

Google Search Console and analytics

What are the main metrics in Search Console’s Performance report?

Clicks, impressions, click-through rate (CTR) and average position, which you can filter by query, page, country, device and date.

What is the difference between Search Console and Google Analytics 4?

Search Console shows how your site performs in Google Search before the click (queries, impressions, indexing). GA4 shows what visitors do on the site after they arrive, from all channels (engagement, key events such as enquiries). More: Search Console vs Google Analytics 4.

What is bounce rate in GA4?

The percentage of sessions that were not engaged. An engaged session lasts more than 10 seconds, has a key event or has at least two page views. It is an analytics measure, not a Google ranking factor.

AI search, AEO and GEO

What are AEO and GEO?

AEO (answer engine optimisation) means structuring content so it clearly answers questions. GEO (generative engine optimisation) means helping your content be understood and cited by AI-generated answers. Both build on normal SEO: crawlable pages, clear answers and trustworthy information. More: SEO vs AEO vs GEO.

How do you get a page into Google’s AI Overviews?

There is no special requirement or markup. Google says pages must be indexed and eligible to show a snippet, and that normal SEO best practices apply (Google: AI features and your website). Clear, accurate, well-structured content gives the best chance, but no one can guarantee inclusion.

Scenario questions

Organic traffic dropped 30% last week. What would you check?

First, whether it is real: check tracking in GA4 and compare with Search Console. Then check the dates against site changes (releases, redirects, robots.txt or noindex changes), Search Console’s Page indexing report and manual actions, and whether the drop is on specific pages, queries, devices or countries. Finally, check for known Google updates or seasonal patterns. I would report findings before making big changes.

A new page is not indexed after two weeks. What do you do?

Inspect the URL in Search Console: is it blocked by robots.txt, marked noindex, canonicalised to another URL, or simply “discovered, not indexed”? Make sure it is in the sitemap, linked from relevant pages, and genuinely useful and not a near-duplicate. Then request indexing.

Two pages compete for the same keyword. How do you fix it?

Compare their performance and content. Usually I would merge them into the stronger page, 301-redirect the other, and update internal links. If they serve different intents, I would make each page’s focus clearer instead.

A client asks you to guarantee the first position on Google. What do you say?

No one can honestly guarantee rankings, because search engines decide them. I would explain what we can control (technical health, content quality, local profile, measurement) and agree on measurable goals such as more qualified visitors and enquiries.
