SEO Interview Questions – 45 Questions and Answers for Freshers (2026)

Here’s how most SEO interviews for freshers in Coimbatore actually go. Ten minutes of basic definitions. Ten minutes on technical SEO and tools. Then one practical question, and that’s where most candidates lose the job. “Our blog traffic fell 40% last month. What would you check first?” Reciting a definition won’t help you there.

So don’t memorise these answers word for word. Understand them, then say them in your own words, with an example from a site you’ve worked on. Interviewers can tell the difference within a minute.

The questions are grouped in 7 sections. Freshers should know sections 1 to 5 well. Sections 6 and 7 are where you stand out.

Section 1: Basic SEO Interview Questions for Freshers

1. What is SEO?

SEO (search engine optimisation) is the work of improving a website so it shows up higher in Google’s free, non-paid results for searches that matter to the business. The goal isn’t traffic for its own sake. It’s the right visitors who become customers.

2. How does Google decide which pages to rank?

Google works in three stages: crawling (Googlebot finds and reads pages), indexing (it stores and understands them) and ranking (it orders indexed pages for each search). Ranking depends on relevance to the query, content quality, page experience, and trust signals such as links.

3. What are the main types of SEO?

On-page SEO (content, titles, headings, internal links), technical SEO (crawling, indexing, speed, mobile), off-page SEO (links, mentions, reviews) and local SEO (Google Business Profile and local signals). Good answers mention that all four work together.

4. What is the difference between organic and paid results?

Organic results are earned through SEO and cost nothing per click. Paid results (marked “Sponsored”) come from Google Ads, and you pay for each click. Paid gives instant visibility. Organic takes longer but keeps bringing traffic without paying per visit.

5. What is a keyword?

A keyword is the word or phrase people type into Google. In SEO, it’s the search term a page is built to rank for, like “seo course in coimbatore”.

6. What are long-tail keywords, and why do they matter?

Long-tail keywords are longer, more specific searches, usually four words or more: “weekend seo course for working professionals”. Each has fewer searches, but they’re easier to rank for and the visitors usually know exactly what they want. That’s why new websites should start with them.

7. What is search intent?

Search intent is the reason behind a search. The four common types are informational (learn something), navigational (find a specific site), commercial (compare options) and transactional (buy or enquire). A page ranks best when its format matches the intent. A “how to” search wants a guide, not a sales page.

8. What is a SERP?

SERP means search engine results page: everything Google shows after a search. Apart from the ten blue links, it can include ads, the map pack, AI Overviews, “People also ask” boxes, videos and images. These extra elements are called SERP features.

Section 2: On-Page SEO Interview Questions

9. What is on-page SEO?

On-page SEO covers everything you change on the page itself: title tag, meta description, URL, headings, content, images, internal links and structured data. For the full list, see our on-page SEO checklist.

10. What is a title tag, and what is the ideal length?

The title tag is the clickable blue headline in Google results. Keep it around 50–60 characters so it doesn’t get cut off, put the main keyword near the start, and write it so people want to click.

11. Is the meta description a ranking factor?

No, Google says it isn’t a direct ranking factor. But it often appears under the title in search results, so a good one improves click-through rate. Keep it under about 155–160 characters and give a clear reason to click.

12. How many H1 tags should a page have?

Use one H1 that describes the page’s main topic and includes the main keyword. Then structure the rest with H2 and H3 subheadings.

13. What is keyword stuffing?

Repeating a keyword unnaturally to try to rank, like “best SEO course, SEO course Coimbatore, SEO course best”. Google treats it as spam. Use the keyword where it fits naturally, plus related words and synonyms.

14. What is alt text, and why is it used?

Alt text describes an image for screen readers and for Google. It helps images appear in Google Images and helps visually impaired users. Describe what’s in the image. Don’t just stuff keywords.

15. What are internal links?

Links from one page on your site to another page on the same site. They help Google discover pages, show which pages are most important and pass authority between pages. Use descriptive anchor text instead of “click here”.

16. What is keyword cannibalisation?

When two or more pages on the same site target the same keyword, so they compete with each other and neither ranks well. The fix is usually to merge them into one stronger page, or change one page to target a different keyword, and redirect where needed.

Section 3: Technical SEO Interview Questions

17. What is the difference between crawling and indexing?

Crawling is Googlebot visiting and reading a page. Indexing is Google storing that page in its database so it can appear in results. A page can be crawled but not indexed if Google decides it isn’t useful or unique enough.

18. What is robots.txt?

A text file at the root of a site (/robots.txt) that tells crawlers which parts of the site they can and can’t crawl. A common follow-up: it blocks crawling, not indexing. To keep a page out of Google, use a noindex tag instead.

19. What is an XML sitemap?

A file that lists the pages you want search engines to find, usually at /sitemap.xml or /sitemap_index.xml. You submit it in Google Search Console. It should only include live, indexable pages.

20. What is a canonical tag?

A tag that tells Google which URL is the main version when similar or duplicate pages exist. For example, a product available at three URLs with different filters should point its canonical to one clean URL.

21. What is the difference between a 301 and a 302 redirect?

A 301 is permanent: the page has moved for good, and Google transfers its signals to the new URL. A 302 is temporary: the original URL is expected to come back. Use 301 when you change URLs or merge pages.

22. What is a 404 error, and is it bad for SEO?

A 404 means the page doesn’t exist. A few 404s for genuinely deleted pages are normal. They become a problem when important pages or pages with backlinks return 404, or when internal links point to them. Fix those with 301 redirects or by updating the links.

23. What are Core Web Vitals?

Three metrics Google uses to measure page experience: LCP (loading, good at 2.5 seconds or less), INP (responsiveness, good at 200 ms or less) and CLS (visual stability, good at 0.1 or less). INP replaced FID in March 2024, so mentioning that shows you’re up to date.

24. What is mobile-first indexing?

Google mainly uses the mobile version of a page to index and rank it. If content is missing on mobile, Google may not count it, even if it’s on desktop.

25. What is structured data (schema markup)?

Code, usually in JSON-LD format, that labels content for search engines: this is a business, a course, an FAQ, a review. It helps Google understand the page and can make it eligible for rich results like star ratings or FAQ dropdowns, though Google doesn’t guarantee they’ll show.

26. What is crawl budget?

The number of pages Google is willing to crawl on a site in a given time. Most small sites never need to worry about it. It matters for large sites with thousands of URLs, where duplicate pages, endless filter URLs and redirect chains waste crawling.

Section 4: Off-Page and Local SEO Interview Questions

27. What is a backlink?

A link from another website to yours. Links from relevant, trusted sites act like votes of confidence and help rankings. One link from a respected industry site is worth more than hundreds from spammy directories.

28. What is the difference between dofollow and nofollow links?

A normal (dofollow) link can pass ranking signals. A link with rel="nofollow" asks Google not to pass them. Google also uses rel="sponsored" for paid links and rel="ugc" for user-generated content like comments. Google treats all three as hints, not strict rules.

29. What is anchor text?

The clickable text of a link. Descriptive anchor text (“technical SEO checklist”) tells Google what the linked page is about. Too many exact-match anchors from external sites can look manipulative.

30. What are bad link-building practices?

Buying links, link exchanges at scale, private blog networks, spammy directory and comment links, and automated link tools. Google’s spam policies call these link schemes, and they can lead to lower rankings or a manual action.

31. What is local SEO?

Optimising a business to appear in Google Maps and local searches like “dentist near me”. The main parts are the Google Business Profile, consistent name, address and phone number across the web, reviews and local pages on the website. Our local SEO checklist covers all 20 steps.

32. What is NAP consistency?

NAP means name, address and phone number. They should be written exactly the same on the website, Google Business Profile and every directory listing. Mismatches confuse Google about where the business really is.

Section 5: SEO Tools and Measurement Questions

33. Which SEO tools have you used?

Be honest and specific. A strong fresher answer: “Google Search Console for indexing and keyword data, GA4 for traffic and conversions, PageSpeed Insights for Core Web Vitals, Screaming Frog for crawling, and the free versions of Ubersuggest or Ahrefs for keyword research.” Then add what you actually did with one of them.

34. What does Google Search Console show you?

Which searches your site appears for, impressions, clicks, average position and CTR. It also shows which pages are indexed and why others aren’t, Core Web Vitals, manual actions and links. It’s the only place where Google reports directly on your site.

35. What is the difference between Search Console and Google Analytics?

Search Console shows what happens before the click: how your site appears in Google search. GA4 shows what happens after the click: what visitors do on your site, from every channel, including conversions.

36. Which metrics would you report to a client?

Organic clicks and impressions, rankings for the main keywords, organic sessions, and most importantly, conversions from organic traffic: enquiries, calls, sales. Rankings without leads don’t mean much to a business owner.

37. What is CTR, and how can you improve it?

Click-through rate is clicks divided by impressions. If a page has many impressions but few clicks, improve the title and meta description so they match the searcher’s intent better, and add structured data where it fits. Our CTR calculator helps you compare pages.

Section 6: Scenario-Based SEO Interview Questions

38. Our organic traffic dropped 40% last month. What would you check?

First, confirm it’s real: compare the same period last year, and check whether tracking broke. Then in Search Console, see whether the drop is across all pages or a few, and whether impressions fell or only clicks. Check for accidental noindex, robots.txt changes, redirects from a recent redesign, a manual action, and whether a Google core update happened on those dates. Then look at which queries lost positions and who replaced you.

39. A new page isn’t showing in Google after two weeks. What do you do?

Use URL Inspection in Search Console. If it says “URL is not on Google”, check for a noindex tag, a robots.txt block or a canonical pointing elsewhere. Make sure the page is in the sitemap and has internal links from important pages, then request indexing. If it’s “Crawled – currently not indexed”, the content may need to be more useful or more unique.

40. The website ranks well but gets very few enquiries. What would you change?

Check whether the ranking keywords match buying intent, or are only informational. Then look at the page: is the offer clear, is the call or WhatsApp button easy to find on mobile, is the form short, does it load fast? Make sure conversions are actually being tracked. Sometimes enquiries happen by phone and nobody counts them.

41. How would you do SEO for a brand-new local business website?

Set up Search Console and GA4, fix the technical basics, and create and verify the Google Business Profile. Research local keywords, build clear service pages with the city in the title, add LocalBusiness schema, list the business on the main directories with the same NAP, and start collecting reviews. Blog content comes after the core pages are done.

42. Two of our pages compete for the same keyword. What would you do?

Look at both pages in Search Console. Decide which one should own the keyword, usually the one with better links and conversions. Merge the useful content from the other page into it and 301 redirect the weaker URL, or re-target the weaker page at a different keyword and update internal links.

Section 7: Advanced and Current SEO Questions

43. What is E-E-A-T?

Experience, Expertise, Authoritativeness and Trustworthiness. It comes from Google’s quality rater guidelines and describes what makes content reliable. It isn’t a single ranking factor, but showing real experience, author details, sources and clear business information helps content perform, especially on money and health topics.

44. How do AI Overviews affect SEO?

For some searches, Google shows an AI-written summary at the top, with links to sources. This can reduce clicks on simple informational queries. To be cited, pages need clear, direct answers, good structure and trustworthy content. It also makes tracking conversions more important than tracking clicks alone.

45. Can AI-written content rank on Google?

Google says it rewards helpful content however it’s produced, but using automation mainly to manipulate rankings is spam. In practice, AI drafts that are fact-checked, edited and given real examples and experience can rank. Mass-produced, unedited AI pages usually don’t.

How to Prepare for an SEO Interview

• Bring one real project. A technical audit or on-page work on any real website, with before-and-after Search Console screenshots. This matters more than any certificate.
• Audit the company’s own website before the interview. Find two or three genuine issues and mention them politely. It shows initiative.
• Know the tools hands-on. Be ready to share your screen and open Search Console.
• Answer scenarios step by step. Say what you’d check first, second and third.
• Be honest about what you haven’t done. “I haven’t worked on an e-commerce site yet, but here’s how I’d approach it” is a good answer.

Frequently Asked Questions About SEO Interviews

What questions are asked in an SEO interview for freshers?

Freshers are usually asked what SEO is, on-page vs off-page SEO, what keywords and backlinks are, crawling and indexing, robots.txt, sitemaps, canonical tags, Core Web Vitals, which tools they’ve used, and one simple scenario like what to check when traffic drops.

Do I need a certificate to get an SEO job?

A certificate helps, but most employers care more about practical work. A portfolio showing a real audit, the fixes you made and the results in Search Console is usually more convincing than a certificate alone.

How do I answer “What SEO tools do you use?”

Name the tools you’ve actually used and give one example of each. For example: “I used Search Console to find pages that weren’t indexed, then fixed a wrong canonical tag.” Don’t list paid tools you’ve never opened.

How long does it take to prepare for an SEO interview?

If you already know the basics, two to three weeks of daily practice on a real website, plus revising these questions, is usually enough for a fresher role. Starting from zero, a structured course of two to three months is more realistic.

What is the salary of an SEO fresher in India?

It varies by city and company. In Coimbatore, most SEO freshers start somewhere around ₹12,000 to ₹22,000 a month. Candidates with a strong project portfolio can negotiate at the higher end. Our fresher salary guide breaks this down by role.
