Basic SEO Interview Questions and Answers for Freshers

Basic SEO interview questions and answers form the foundation of what recruiters expect all candidates to know. First thing to remember is that these questions assess your fundamental understanding of search engine optimization concepts.

1. What is SEO?

SEO (Search Engine Optimization) refers to the practice of optimizing your website to improve its visibility on search engines. In essence, SEO helps search engines understand your content and connects it with users by delivering relevant results based on their search queries. The goal is to rank higher on search engine results pages (SERPs) for keywords valuable to your target audience, ultimately driving qualified traffic to your site.

2. Why is SEO important?

SEO matters because it significantly impacts a business’s online visibility and growth. According to research, organic search delivers 53% of all website traffic. Additionally, SEO helps businesses connect with potential customers who are actively searching for their products or services. Without proper SEO, your rankings become vulnerable to competitors, and considering only a small fraction of users go beyond the first page of search results, optimizing for search engines becomes vital for maximum visibility.

3. What are the types of SEO?

SEO can be divided into three main categories:

• On-page SEO: Actions taken on your website content to improve rankings, such as keyword optimization, content creation, and HTML structure improvements.
• Off-page SEO: Activities outside your website that influence rankings, primarily focusing on building backlinks and mentions from other sites.
• Technical SEO: Backend optimizations that improve site crawlability, user experience, and speed.

Other specialized types of SEO include local SEO, e-commerce SEO, image SEO, and mobile SEO, each focusing on specific optimization needs.

4. What is a keyword, and why is it important?

Keywords are words and phrases that searchers enter into search engines to find content, also called “search queries”. They’re crucial because they:

• Help you understand what people are searching for
• Direct how you connect with your audience
• Determine how people find you through search
• From the foundation of any SEO campaign

Keywords are as much about your audience as your content—they bridge the gap between what people want and what you offer. Without keywords, SEO would be virtually impossible.

5. What is the difference between on-page and off-page SEO?

On-page SEO focuses on optimizing elements within your website that are under your control. This includes title tags, meta descriptions, content, internal links, and HTML structure. Conversely, off-page SEO involves actions taken outside your website to improve its search engine rankings, primarily through building backlinks, social signals, and mentions.

In short, on-page SEO makes your content better for users and search engines, while off-page SEO improves your website’s reputation and authority. Both are essential for a comprehensive SEO strategy.

6. What is a meta description?

A meta description is an HTML tag that provides a short, relevant summary of what a webpage is about. Although not a direct ranking factor, it serves as a pitch to convince users that your page is exactly what they’re looking for.

An effective meta description:

• Appears below the title in search results (typically 120-160 characters)
• Influences click-through rates from search results
• Should be unique for each page
• Often appears in social media previews
• Can include information like author, publication date, or product details

While Google may sometimes replace your meta description with page content that better matches a user’s query, creating compelling descriptions remains important for driving clicks.

Intermediate SEO Interview Questions

Intermediate SEO interview questions and answers test your ability to go beyond basics and demonstrate practical knowledge of search optimization techniques. These questions typically appear after you’ve established your foundational understanding.

7. What is keyword research, and how do you do it?

Keyword research is the process of finding and analyzing search terms that people enter into search engines, to use that data for specific purposes like SEO or marketing. Effective keyword research helps you identify your SEO sweet spot—the overlap between keywords that aren’t too competitive and topics where you can create excellent content.

To perform keyword research:

1. Start with seed keywords related to your products/services
2. Use keyword research tools to expand your list
3. Analyze metrics like search volume and keyword difficulty
4. Determine the user intent behind each keyword
5. Select keywords that balance search volume with competition level

8. What are long-tail keywords?

Long-tail keywords are longer, more specific keyword phrases that visitors typically use when they’re closer to making a purchase or when using voice search. These keywords generally have lower individual search volumes but collectively make up about 70% of all searches.

Long-tail keywords are valuable because they:

• It is easier to rank for due to lower competition
• Attract more targeted traffic with higher conversion potential
• Typically have a lower cost-per-click in paid advertising
• Help you create more specific, targeted content

For example, “shoes” is a head term, while “comfortable running shoes for flat feet” is a long-tail keyword.

9. What is domain authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine results pages compared to competitors. It ranges from 1 to 100, with higher scores indicating greater ability to rank.

Despite the common misconception, Domain Authority is not a direct Google ranking factor. Rather, it’s a comparative metric to evaluate your website’s search performance against competitors. Websites with high DA typically have strong inbound links, robust off-page SEO strategies, and valuable web pages.

10. What is a backlink?

Backlinks are hyperlinks that point from one website to another. For instance, if site A links to site B, that link is a backlink for site B.

Backlinks function as endorsements for the linked website, signaling to search engines that others vouch for your content. Hence, the more high-quality backlinks a website has, the more likely it is to rank higher in search results. Quality matters more than quantity—links from authoritative, relevant sites carry more weight than those from low-quality sources.

11. What is anchor text?

Anchor text is the clickable text in a hyperlink that tells users and search engines something about the page you’re linking to. Good anchor text is descriptive, concise, and relevant to both the page it’s on and the page it links to.

Types of anchor text include:

• Exact-match: Contains the exact keyword the linked page targets
• Partial-match: Contains variations of the target keyword
• Branded: Uses a brand name
• Generic: Uses non-descriptive phrases like “click here”

Effectively using anchor text helps search engines understand content relationships and improves user experience by setting clear expectations about linked content.

12. What is a sitemap?

A sitemap is a file or webpage that helps both human visitors and search engines navigate your website. It serves as a roadmap of your content, enhancing your website’s visibility in search results.

There are two main types:

• HTML sitemaps: Help human visitors navigate your site through clickable links
• XML sitemaps: Help search engines discover your URLs efficiently, typically including information about when content was last modified

While sitemaps aren’t a direct ranking factor, they provide significant SEO benefits by helping search engines discover and crawl your content more efficiently, particularly for new sites or those with complex structures.

Technical SEO Interview Questions

Technical SEO interview questions and answers explore your understanding of website optimization for search engines beyond content creation. These questions assess your knowledge of the technical elements that impact website performance and visibility.

13. What is a robots.txt file?

A robots.txt file is a plain text file placed in the root directory of a website that communicates with web crawlers or bots. This file provides instructions on which parts of your website search engines should or shouldn’t crawl. Essentially, it serves as a set of directives that help manage bot activity across your website.

The basic syntax includes:

• User-agent: Specifies which bots the rule applies to
• Disallow: Prevents crawlers from accessing specific files or directories
• Allow: Overrides a disallow rule for specific pages

14. What is an XML sitemap?

An XML sitemap is a file that stores the full architecture of your site content for search engines to crawl and index. It helps search engines understand your site structure and discover all URLs efficiently. Unlike HTML sitemaps (designed for users), XML sitemaps are specifically created for search engines.

XML sitemaps improve SEO by:

• Making important content findable for search engines
• Helping search engines discover content updates quickly
• Providing context about site architecture
• Supporting multilingual site structures through hreflang tags

15. What is a canonical tag?

A canonical tag (rel=”canonical”) is an HTML element that informs search engines which version of a page should be considered the master copy when duplicate or similar content exists. It helps prevent duplicate content issues by specifying your preferred URL.

The tag appears in the HTML head section like this: 

<link rel=”canonical”href=”https://example.com/preferred-url-here/” />

16. What is a 301 redirect?

A 301 redirect is an HTTP status code that permanently moves a page from one URL to another. The code “301” signals to search engines that the move is permanent. Furthermore, it passes full link equity, ensuring the new URL inherits the old page’s ranking power.

Common use cases include:

• Website migrations
• Fixing URL slugs
• Consolidating duplicate pages
• Redirecting deleted pages to relevant replacements

17. What is page speed, and why does it matter?

Page speed measures how quickly the content of a webpage loads. Specifically, it encompasses several metrics, including Time to First Byte (TTFB), First Contentful Paint (FCP), and First Input Delay (FID).

Page speed is important primarily because:

• It’s a confirmed ranking factor on both desktop and mobile
• Google prioritizes faster pages in search results
• Users typically abandon pages that take more than three seconds to load
• It significantly affects user experience and engagement

18. What is mobile-first indexing?

Mobile-first indexing means Google uses the mobile version of a website as the primary basis for indexing and ranking rather than the desktop version. Consequently, the mobile experience of your website directly impacts how it performs in search results.

Key aspects include:

• Google prioritizes the mobile version when crawling and indexing
• Mobile-unfriendly sites can experience ranking drops
• Content parity between mobile and desktop versions is essential
• Proper viewport settings and responsive design are crucial for success

Advanced SEO Interview Questions and Answers

Advanced SEO interview questions and answers separate entry-level candidates from experienced professionals who understand complex optimization strategies. Answering these questions effectively demonstrates your in-depth understanding of how search engines evaluate content quality and technical implementation.

19. What is E-E-A-T in SEO?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It’s a framework Google uses to assess content quality, especially for topics that impact a person’s health, finances, or safety. In this framework, trust is the most critical component, with the other elements contributing to it. Ultimately, high E-E-A-T content is more likely to rank well as Google prioritizes reliable information.

20. What is structured data?

Structured data is a standardized format that provides specific information about a page and classifies its content. It helps search engines understand your content better and potentially display it as rich results. Using schema.org vocabulary (typically implemented as JSON-LD), structured data describes elements like recipes, reviews, events, and products in a way machines can interpret.

21. What are rich snippets?

Rich snippets (or rich results) are enhanced search listings that display additional information beyond the standard title, description, and URL. They’re powered by structured data and appear as recipes with images and ratings, FAQ accordions, review stars, or event details. According to case studies, pages with rich results have shown up to 82% higher click-through rates than standard results.

22. What is the Helpful Content Update?

The Helpful Content Update is a significant Google algorithm change launched in 2022 that rewards people-first content while penalizing content created primarily for search engines. It introduced a site-wide ranking signal that identifies unhelpful content, potentially affecting your entire domain. This update prioritizes content showing expertise, depth of knowledge, and genuine value to users.

23. How do you recover from a Google penalty?

Recovering from a Google penalty involves:

1. Identifying the penalty type (algorithmic or manual) through Google Search Console
2. Investigating the root cause (spammy backlinks, keyword stuffing, thin content)
3. Fixing the underlying issues thoroughly
4. Submitting a reconsideration request for manual penalties

Recovery can take anywhere from 10-30 days for manual penalties, while algorithmic penalties might require up to six months for full recovery.

24. What is the role of Core Web Vitals?

Core Web Vitals are metrics that measure real-world user experience on your website. They include Largest Contentful Paint (LCP), measuring loading performance (should be under 2.5 seconds); Interaction to Next Paint (INP), measuring responsiveness (should be under 200ms); and Cumulative Layout Shift (CLS), measuring visual stability (should be under 0.1). These metrics directly impact your search rankings as part of Google’s page experience signals.

Scenario-Based and Tool-Related Questions

Scenario-based and tool-related SEO interview questions and answers test your ability to apply knowledge in real-world situations. These questions reveal your practical experience and problem-solving skills beyond theoretical understanding.

25. How do you handle a sudden drop in traffic?

When facing a sudden traffic drop, I follow this approach:

1. Check Google Analytics and Search Console for the exact timing and affected pages
2. Look for Google algorithm updates that coincided with the drop
3. Verify if there are any manual actions in Search Console
4. Check for technical issues like crawlability or indexation problems
5. Examine whether SERP features have changed for your key terms

For recovery, address the specific cause—fix technical issues, improve content quality after algorithm updates, or submit a reconsideration request for manual penalties.

26. How do you measure SEO success?

I track multiple metrics to measure SEO success:

• Organic traffic growth from search engines
• Keyword rankings for target terms
• SERP visibility percentage across important keywords
• Click-through rate from search results
• Conversion rates from organic traffic
• Domain authority and backlink quality
• Core Web Vitals and technical health scores

The most important metrics vary by business goals—leads generated for B2B companies versus revenue for e-commerce sites.

27. What SEO tools do you use regularly?

My essential SEO toolkit includes:

• Google Search Console and Google Analytics for performance tracking
• Semrush or Ahrefs for keyword research and competitor analysis
• Screaming Frog for technical site audits
• PageSpeed Insights for Core Web Vitals monitoring
• Yoast SEO or Rank Math for WordPress optimization
• SE Ranking for tracking rankings and SERP features

28. How do you stay updated with SEO trends?

I stay current with SEO by following:

• Google’s official channels, like Search Central Blog and announcements
• Industry publications like Search Engine Journal and Search Engine Land
• Webinars and online conferences from respected SEO professionals
• LinkedIn posts from SEO thought leaders
• Online communities and forums discussing algorithm updates

29. How do you handle duplicate content?

To fix duplicate content issues, I implement:

• 301 redirects from duplicate pages to the canonical version
• Canonical tags in the HTML to specify the preferred URL
• Noindex tags for pages that should remain accessible but not appear in search results
• Content differentiation by rewriting similar pages with unique perspectives
• Properly structured pagination with rel=”next” and rel=”prev” attributes

30. How do you optimize content for voice search?

For voice search optimization, I focus on:

• Using conversational, natural language that matches how people speak
• Targeting long-tail question keywords (who, what, where, when, how)
• Creating direct answer snippets at the top of content (featured snippet optimization)
• Improving page speed since voice search users want quick answers
• Adding schema markup to help search engines understand content context
• Optimizing for local “near me” searches, which are common in voice queries
