1. What is SEO?

The practice of optimizing a website's architectural layout is known as SEO. It helps in content relevancy and link attractiveness so that its pages are more readily found, more relevant, more prominent in response to use web searches, and hence rank higher in search engines.

SEO aids in increasing a company's exposure. 

Organic results are more trusted than sponsored results. Having your website featured for the appropriate keywords might bring you a lot of visitors.

SEO techniques enable companies to rank for possible keywords without paying a dollar on search engine marketing, resulting in the most valuable visitors. It's known as 'organic,' 'free,' and 'natural' outcomes. There are several optimization techniques and actions that Users should carry out to ensure that your site is SEO friendly and ranks for desired keywords.

2. Why is SEO important to businesses?

One of the famous jokes that run amongst individuals in the web sector is that you should put it on Google's second page if you want to conceal a corpse. Because just a small percentage of people go beyond the first page of Google results, your rivals will steal all of your clients if your industry isn't on the first page. With each position, CTR lowers progressively. One significant benefit of SEO over PPC is that, unlike PPC, your results will not end if you quit doing SEO today. SEO is crucial if a firm wants to grow sales without splurging on promotions.

4. What is an organic result?

Organic results are provided by search results based on relevance, quality, and other ranking variables and are one of the two kinds of search results in SERP. Organic results, sometimes known as 'free results' or 'natural outcomes,' are unpaid. Several criteria determine the ordering of organic results.

The organic results appear underneath the sponsored results. Organic results cannot be influenced by charging Google, or they may be improved by ensuring superior data and allowing users to engage with it.

5. What is a paid result?

Paid results refer to advertisers who pay to show their ads alongside better organic results on SERPs. Paid results are instantaneous, and advertisers are not obligated to enhance their website and content to rank. Your Max CPC and quality score will determine your position. The more money you save, the better your quality score.

6. What is Google Sandbox?

The Google Sandbox Effect asserts that new sites are often on probation (inside a box) and hence cannot rank successfully for their most important keywords. 

According to the notion, Google needs to contemplate before leaving the fictitious location. It might be caused by constructing too many connections in a short amount of time.

It was never formally announced, although it was discussed while Google discussed various things.

7. What is Google Autocomplete?

Google Autocomplete is defined as a search engine feature that works with search engines such as Google. When you start writing in the search field, Google autocomplete offers you a list of suggestions to help you finish your query. It enables users to complete searches less quickly and with much less initiative, particularly useful when searching on a mobile device. Search recommendations are strongly impacted in queries as well as your previous searches.

8. What is a TLD?

The last portion of an internet address is the top-level domain (TLD). There are many sorts of TLDs accessible, such as.com,.net,.org,.co.in, and so on.

9. What is ccTLD?

A ccTLD stands for a country code top-level domain. The domain extension for each nation is distinct. All ccTLDs have just two characters. For instance,.in stands for India, while.us stands for the United States.

10. What are keyword frequency, Keyword Density, Keyword Difficulty, and Keyword Proximity?

• Keyword Frequency: The amount of times a specific keyword phrase occurs on a web page is known as keyword frequency. When optimizing a web page, we must be careful not to overuse the term to the point of keyword stuffing. 
• Keyword Difficulty: The keyword difficulty metric measures how tough it is to rank for a given term based on its prominence and competitors. The more complicated the keyword, the more time or backlinks are required.
• Keyword Density: Keyword density is the proportion of times a term or phrase occurs on a web page. Search engines may mistake the keyword frequency for term stuffing when the keyword frequency is significantly over the optimal level. Consequently, we must ensure that the keyword density for any significant or secondary search keywords is not excessive. For example, if a term occurs five times in a 200-word piece, the density is 2.5 percent. Although there is no perfect keyword density, 3–4% is recommended practice for SEO.
• Keyword Proximity: The distance between two terms on a web page is measured by keyword proximity.

11. What is the definition of a long tail keyword?

Long-tail phrases include more than four words and are very specialized. Long-tail keywords, as opposed to broad keywords, indicate the purpose and quality of the search, leading to a high number of sales if adequately targeted. The ideal way to use long-tail keywords is on a blog. They have a lower search volume than broad keywords, but when many long-tail keywords are combined, we receive a lot of traffic with a high conversion rate.

12. What is the definition of bounce rate in SEO?

No SEO Interview Questions and Answers guide would be complete without this question. Bounce rate refers to the proportion of website visitors who depart the landing page without viewing any other pages or taking action.

Bounce rate is defined as single-page visits divided by all sessions, or the proportion of all sessions on your site in which people saw just one page and sent only one request to the Analytics server, according to Google.

To reduce bounce rates, boost page engagement (through internal links, CTAs, etc. ), improve page performance, and provide consistent user interaction, among other things.

13. What is robots.txt?

It's a text file called robots.txt. It's everything done via this file. It addresses search engine crawlers how to index and cache a website, a webpage or directory's file, as well as a domain.

14. What are anchor texts? What role does anchor text have in SEO?

The accessible text in a hyperlink is called anchor text. Anchor texts assist users in understanding the purpose of the page. If keywords are used, it also has SEO value. However, if you are too optimized, Google may penalize you.

Natural anchor text is vital, as is variety, such as branded, long tail, picture links, partial and precise matches. Search engines utilize anchor text to determine the page's context to which it is connected. This has some SEO significance in determining what the site is about for search engines.

15. What is Robot's Meta Tag?

With directives like FOLLOW, NOFOLLOW, INDEX, and NOINDEX, the Robots Meta Tag directs search engines to handle the page.

16. What is an HTML Sitemap?

HTML sitemap is a new website that allows people to view a list of pages structured to understand and traverse the site quickly. An HTML sitemap isn't essential if your website has a few user-accessible sites. HTML sitemaps are very beneficial if you have a large website.

17. What is an XML Sitemap?

Extensible Markup Language (XML) is an acronym for "Extensible Markup Language." The purpose of an XML sitemap is to provide search engines with information about the most recent changes made to them. It contains a list of websites and the frequency with which they are updated. Using an XML sitemap, we may request that search engines regularly scan and index our essential pages. When a search engine discovers a website, among the first things it looks for is a sitemap.

18. Explain LSI

LSI Keywords are semantically linked to the principal term used by visitors in search engines.

When we use LSI keywords to improve a page, the keyword relevance will rise. LSI allows you to optimize keywords on a web page without worrying about keyword stuffing. Google's algorithm uses LSI keywords to determine the relevance of a search phrase. It aids search engines in deciphering the semantic structure of keywords and extracting the meaning of the text to provide the best SERP results.

19. What makes a website search engine friendly?

Several factors make a website search engine friendly, including keywords, quality content, titles, metadata, etc. A website needs these factors to be ranked by a search engine and therefore found by a user.

20. How do you measure SEO success?

You might want to answer this question based on the type of company you’re interviewing for, as goals might differ. In addition, there are a variety of ways to measure key performance indicators (KPIs) and, therefore, success. During an SEO interview, possible answers might include increasing traffic to a website or particular landing page, increasing conversions such as newsletter signups or sales, growing the number of inbound links, driving traffic for a particular keyword phrase, or increasing referral traffic. It’s critical that an SEO professional measures result to know if the tactics and strategy need to change to succeed.

21. How did you learn SEO?

Obviously, this answer will depend on your individual situation, but it matters because a potential employer wants to ensure that you are well-versed in SEO best practices. If you learned SEO by the seat of your pants at your last job because someone had to do it, an employer might doubt the quality of the skillset you offer. And, if that’s the case, you can always get certified before applying for that job to ensure you are well trained!

22. Which SEO tools do you regularly use?

Various tools can make SEO jobs more accessible, and choosing the best one depends on your needs.

• ahref
• kwfinder
• sem haste
• quack SEO
• Moz.

23. How do you approach keyword research?

As with the question above, your answer might vary. You’ll want to explain which keyword tools you use for research, as well as how you go about it. For example, if you use Google Keyword Planner to do your keyword research, then that’s your answer for the tool used. But you must also explain how you go about it. You must demonstrate you do more than simply guess at a keyword and type that into the tool before checking the results. For example, perhaps you use personas to consider potential problems a prospect faces, and you look for keywords around that. You should also explain that you consider longer keyword phrases, search volume, and the competitiveness of a keyword. Demonstrate that you know how to find the sweet spot in keyword research, where the keyword narrower so it’s targeted and has good search volume, but is not highly competitive.

24. What is link building and why does it matter?

Google exists to serve the searcher. That means Google is constantly trying to determine which results are most relevant to any given searcher and any given time. In addition to relevance, Google considers credibility too. So the search engine looks to see if other websites have linked to yours. If so, that means your content is worth linking to and is, therefore, more credible when compared to a website not linked to externally. In a nutshell, link building is what SEO professionals do to try and get links to their websites in order to improve search results.

25. What are backlinks?

When a website links to another, a backlink is established. In other words, Backlinks to your website are essentially a signal to search engines that people endorse your content.

26. What is page speed and why does it matter?

Page speed refers to how fast your site loads for a user, something Google takes into account while ranking websites since a faster loading page directly translate to better user experience. If the interviewer asks what you would do to increase page speed, describe how you’ve achieved this in the past with examples such as reducing image sizes, enabling compression, reducing redirects, removing render-blocking JavaScript, leveraging browser caching, improve server response time, using a content distribution network to compress files, optimizing the code, etc.

27. What method do you use to redirect a page?

In general, 301, 302, and Meta Refresh are the three most widely used redirects.

Meta Refresh, 

301, "Moved Permanently"—recommended for SEO

302, "Found" or "Moved Temporarily."

28. How can you do SEO for a video?

Videos are growing increasingly popular on the web, which can improve SEO if the videos produced get attention and therefore share and backlinks. But to get the video seen can require SEO to get it found, and Google can’t watch a video. It needs the same types of information required for text-based pages to rank a video. Including the transcript as a text is an easy way to do SEO for a video because search engines can crawl the text. In addition, the same attention should be paid to keywords, page titles, and descriptions.

29. Which meta tags matter?

Meta tags have changed since SEO became a common practice, but two remain critical: the page title and the meta description. Stick to these when answering your interview question. The page title (sometimes called SEO title) plays an important role in ranking but it is also important because it is the title that shows on the Search Results Page (SERP). It must use a keyword to rank well with Google but it must also be compelling so a user will want to click on it. The meta description does not affect ranking, but it also plays a role in the SERP because it also must make the user want to click on the search result. You should also mention that Google recently increased the character length limit of meta descriptions to around 280 to 320 (no one is sure of the actual limit yet).

30. What is the difference between a do-follow and no-follow and how are they used?

Nofollow links exist because we don’t want every single webpage or link to be something a search engine crawls and ranks. Therefore, no-follow link attributes tell search engine bots not to follow a certain link. The link is still clickable for a user, but not followed by a bot. On the other hand, all other links could be considered do-follow links, even though they don’t have to have special attributes to tell the search engine bots to follow them—the bots will by default.

31. Which SEO factors are not in your control?

The biggest SEO factor not in your control is Google! How exactly Google ranks websites is unknown. The company does not make public the search algorithms it uses, although SEO professionals have determined the best practices we adhere to in order to achieve results. However, Google doesn’t like young domains that aren’t yet tried-and-true, and you can’t control that if you’re launching a new site. Nor can you force people to link to your site, share your content, spend more time on your site, or come back to your site for another visit. Google looks favorably on all of these factors and ideally a marketing department is working hard to create content and user experiences that will make these happen, but these factors are beyond the control of the SEO person.

32. What is on-page vs off-page SEO?

This gets back to the question about the factors that are outside of your control. On-page SEO includes the factors you can control, such as keywords, content, page structure, internal linking, load time, etc. Off-page SEO includes those factors you can’t control, such as backlinks.

33. What are some black hat SEO practices to avoid?

Ideally, you won’t interview with an organization that condones any black hat SEO practices, but it might be a trick question to make sure you wouldn’t use them either. Cloaking, keyword stuffing, copying content from another site, exchanging or trading links, buying links, hiding text, and using a link farm are all underhanded techniques frowned upon—and penalized—by Google.

34. What is the relationship between SEO and SEM?

SEO stands for Search Engine Optimization and SEM stands for Search Engine Marketing. The biggest difference between the two is that SEO is free and SEM is paid. SEM includes pay-per-click advertising and display ads that are purchased. Despite the major difference between the two, they work best in unison.

35. What qualities are required in order to be effective in an SEO role, in your opinion?

This is a question requiring a subjective answer, but you might want to think through all of the different skill sets required to be good at this kind of job. An SEO professional must have good research skills, for one thing, as well as strong analytical skills. An ability to spot trends and adapt to change is also important. As you think through the answer to this SEO interview question, consider your own strengths as an SEO professional. Could you weave those into this answer?

The  SEO interview questions listed above are aimed towards professionals with about a year’s worth of experience. They’re likely transitioning into SEO as part of establishing a digital marketing career and perhaps have only a certification and not a reputed track record. For those with more experience, read on for advanced SEO interview questions.
