Frequently Asked SEO Interview Questions

Q1. What is SEO?

SEO stands for Search Engine Optimisation. When a website or web page is optimised, it raises its exposure and rating on search engine result pages (SERPs), which increases organic (non-paid) traffic.

Q2. What are the key components of SEO?

The critical SEO components include keyword research, on-page optimisation, off-page optimisation, technical SEO, and user experience.

Q3. Distinguish between organic and paid results.

Organic results are the natural listings on search engine result pages that appear based on their relevance to the search query. On the other hand, Paid results are advertisements that website owners pay for to appear at the top or side of the SERPs.

Q4. What is a keyword?

Keywords are words or phrases users enter into search engines to find information. In SEO, keyword research identifies and selects relevant keywords for optimising a website’s content.

Q5. How do search engines affect the ranking of websites?

Search engines use complex algorithms that consider various factors, like relevance, authority, and user experience, to determine the ranking of websites. These algorithms analyse on-page and off-page factors to determine the most relevant and valuable pages for a search query.

Q6. What is on-page optimisation?

On-page optimisation refers to optimising individual web pages to improve search engine rankings. It optimises page titles, meta descriptions, headings, content, URL structure, and internal linking.

Q7. What is off-page optimisation?

Off-page optimisation involves actions outside your website to improve its visibility and authority. It includes building backlinks, social media marketing, influencer outreach, guest blogging, and online reputation management.

Q8. Why are backlinks essential in SEO?

Backlinks are essential for SEO because search engines view them as a recommendation or vote of confidence for the information on your website.

Q9. Explain the importance of website speed in SEO.

Website speed is crucial for both user experience and SEO. Search engines consider website speed a ranking factor because fast-loading websites provide a better user experience. Slow-loading websites tend to have higher bounce rates and lower conversion rates.

Q10. Tell something about duplicate content and how does it affect SEO?

Duplicate content is identical or similar content on multiple web pages. Search engines strive to provide unique and valuable content to their users. Having duplicate content can confuse search engines and lead to lower rankings or penalties.

To optimise website URLs for SEO:

  • Keep them short and descriptive
  • Use relevant keywords
  • Use hyphens to separate words
  • Avoid using special characters, numbers, or dates in URLs

Q12. What is anchor text?

Anchor text is referred to as the visible, clickable text in a hyperlink. It helps search engines understand the topic or content of the linked page. Using descriptive and relevant anchor text for internal and external links is essential.

Q13. Explain the importance of social media in SEO.

While social media signals themselves may not directly impact SEO rankings, they can indirectly influence SEO performance. Social media increases brand awareness and attracts backlinks, all contributing to improved organic rankings.

Q25. Distinguish between indexing and ranking.

A well-structured site architecture improves user experience and facilitates website crawling and indexing by search engines. It also helps distribute authority and ranking signals to essential pages.
