Common SEO Interview Questions (With Answers)
What is SEO and why is it important?
SEO stands for Search Engine Optimization, and it’s the practice of improving website visibility in search engines.
According to BrightEdge, 68% of online experiences begin with a search engine (source).
SEO is essential because it drives organic traffic, builds credibility, and contributes to long-term online growth.
What are the main types of SEO?
There are three key types:
- On-page SEO: Content, page links, meta tags, headings, and internal links.
- Off-page SEO: Backlinks, brand mentions, and social signals.
- Technical SEO: Site speed, mobile-friendliness, crawlability, indexability, and structured data.
Each plays a vital role in boosting rankings and improving user experience.
How do search engines work?
Search engines crawl the web, index content, and use algorithms to rank pages. We must align our SEO efforts with how these engines read and evaluate content.
What tools do you use for SEO?
Popular tools include:
- Google Search Console and Analytics
- Ahrefs, SEMrush, or Moz for research
- Screaming Frog for audits
- Surfer SEO or Clearscope for content optimization
Mention tools that show your efficiency and technical know-how.
How do you measure SEO success?
Key metrics include:
- Organic traffic
- Keyword rankings
- Click-through rate (CTR)
- Conversion rate
- Bounce rate
Use real examples to showcase success. For instance, “We grew organic traffic by 60% in 4 months after optimizing blog content.”
Tip: Highlight your hands-on experience, but also your ability to interpret data.
Technical SEO Interview Questions (With Answers)
What is crawlability and indexability?
Crawlability is a search engine’s ability to access your content. Indexability is whether that content gets added to Google’s index.
Tools such as Screaming Frog and Google Search Console are useful for identifying crawl and indexing issues.
What is the difference between 301 and 302 redirects?
- 301: Permanent redirect; passes link equity.
- 302: Temporary redirect; does not pass full SEO value.
Use 301s when you’ve moved content for good.
How do you find and fix technical SEO issues in Google Search Console?
- Identify errors under the Indexing tab.
- Fix crawl errors (404s, server issues).
- Submit updated sitemaps.
- Utilize the URL Inspection Tool to request a re-indexing of your page.
What is canonicalization?
It’s the process of telling search engines which version of a URL you want to rank. Canonical tags prevent duplicate content issues.
Let’s say your website has a product page that can be accessed through multiple URLs:
- https://example.com/product/blue-shoes
- https://www.example.com/product/blue-shoes
- https://example.com/product/blue-shoes?ref=facebook
- https://example.com/product/blue-shoes/
These URLs all relate to the same product, however, search engines might interpret them as different pages. This could cause problems with duplicate content and reduce the strength of your SEO signals.
On each of these pages, you add this canonical tag in the <head> section of the HTML:
<link rel=”canonical” href=”https://example.com/product/blue-shoes”>
This tells search engines that “https://example.com/product/blue-shoes” is the preferred (canonical) version of the page, and all SEO value should be attributed to it.
What are the most important metrics to follow on Core Web Vitals?
Focus on:
- Largest Contentful Paint (LCP): Improve loading speed.
- First Input Delay (FID): Minimize JavaScript.
- Cumulative Layout Shift (CLS): Use proper dimensions for images and ads.
Tools: PageSpeed Insights, GTMetrix, and Lighthouse.
How do you handle site migrations from an SEO perspective?
- Crawl the old site.
- Map redirects (old to new URLs).
- Maintain XML sitemaps.
- Monitor traffic and rankings post-launch.
Tip: Use concrete examples from past projects to explain your technical workflows.
Scenario-Based and Strategy Questions
How would you improve a website that has lost rankings suddenly?
We’d first check for algorithm updates or manual penalties. Then we’d audit content, backlinks, and technical health.
For example, after a recent update, one client’s blog traffic dipped 30%. We refreshed outdated content, improved internal linking, and fixed broken backlinks, recovering traffic in 3 weeks.
Describe your approach to keyword research.
We use a mix of tools (Ahrefs, Google Keyword Planner) and analyze:
- Search intent
- Competitor keywords
- Long-tail variations
Our focus is always on user intent and content clusters for topical authority.
How do you build a backlink strategy?
We use white-hat methods:
- Guest posting
- Broken link building
- Digital PR
- Creating link-worthy content (e.g., statistics pages, tools)
We also monitor link profiles for spammy backlinks.
What steps would you take to audit a new client’s website?
- Run a full crawl
- Check indexing and sitemaps
- Audit on-page SEO (titles, descriptions, headings)
- Review backlinks
- Analyze performance metrics
Then, we prioritize fixes by impact and difficulty.
How would you approach SEO for a multilingual or e-commerce site?
For multi-language:
- Implement hreflang tags correctly
- Localize, not just translate
For eCommerce:
- Optimize product pages
- Use structured data
- Prevent thin or duplicate content
Tip: Strategy answers should show a balance of SEO knowledge and business sense.
