What questions come up in SEO job interviews?

Interviews for SEO-related roles often abound with questions designed to verify both the candidate’s theoretical and practical knowledge in the field of website optimisation. Recruiters may cover topics ranging from basic SEO principles to more complex technical issues.

One of the key areas is Google ranking factors. Candidates should be prepared for questions about the elements that influence a website’s SEO, such as:

• content quality,
• page load speed,
• the value of links pointing to it.

It is also important to be able to distinguish between on-page SEO (e.g. optimising meta tags or headings) and off-page SEO (e.g. link-building strategies).

Another important topic is keyword research. Recruiters often check familiarity with analytical tools such as Google Keyword Planner or Ahrefs. The candidate should also demonstrate the ability to select key phrases, taking into account their competitiveness and user intent.

In technical matters, questions often arise about indexing pages in Google. You may be asked to explain how to check a page’s indexing status or which methods speed up this process for new subpages.

Increasingly often, recruiters raise the topic of Core Web Vitals, i.e. metrics related to page performance (LCP, FID, CLS). Candidates should know their significance and ways to optimise these indicators.

For more experienced specialists, questions may concern specific SEO challenges, such as keyword cannibalisation or indexing issues. Recruiters may also ask about experience in effective link building and strategies for acquiring valuable backlinks.

Example questions include:

• What tools do you use for keyword analysis?
• How do you respond to a drop in a site’s rankings?
• How do you measure the effectiveness of your link-building strategy?

Answers should be based on real examples from previous projects or case studies. This shows not only theoretical knowledge, but also a practical approach to solving SEO problems.

How to prepare for an SEO interview?

Preparing for an interview for an SEO specialist role requires both theoretical knowledge and a practical approach. Start by researching the company thoroughly you are interviewing with. Analyse its current SEO strategy, check how it performs in search results, and pay attention to any issues such as low visibility or difficulties with page indexing.

Next, focus on preparing specific examples from your experience. Talk about SEO campaigns that delivered measurable results – increased organic traffic or improved the site’s rankings in search results. This is an excellent opportunity to show your skills in action. Also prepare to discuss how you can contribute to achieving the company’s goals – whether through content optimisation, a linking strategy or other activities.

Don’t forget to prepare questions for the recruiter. Asking about the company’s SEO goals, team structure or the tools used will not only show your commitment, but also help you better understand the employer’s expectations. You might ask, for example, about priorities in technical optimisation or plans related to Google algorithm updates.

It is also worth reviewing the most frequently asked questions during interviews for SEO roles. This will increase your confidence and help you prepare for the discussion more effectively. Topics may include:

• Google ranking factors,
• keyword analysis,
• Core Web Vitals optimisation.

Practise answering questions about technical issues, e.g. relating to page indexing or the use of the noindex metatag.

The interview is your chance to show your value as a candidate. Specific examples of successes and a willingness to propose solutions to the company’s challenges can significantly influence the recruiter’s positive impression and increase your chances of landing your dream role.

What analytical skills are key for an SEO specialist?

An SEO specialist must have strong analytical skills that allow them to interpret data on website traffic, keyword rankings and the effectiveness of campaigns run. It is essential to be proficient with tools such as Google Analytics or Google Search Console, which make it possible to track key performance indicators such as organic traffic, conversion rates or the quality of acquired backlinks.

Data analysis is not only about monitoring statistics, but also identifying trends and problems – for example sudden drops in traffic or low site visibility. Based on this information, the specialist should draw conclusions and implement appropriate optimisation changes. This may mean adjusting the keyword strategy or improving the technical aspects of the website.

An important part of the job is also tracking various success metrics, such as CTR (click-through rate), average time spent on the page or bounce rate. This data makes it possible to assess the effectiveness of SEO activities and adapt the strategy to the current needs of the website.

You cannot forget competitor analysis – tools such as Ahrefs or SEMrush are indispensable for examining the link profiles of other companies and identifying gaps in their SEO strategies. This makes it possible to rank your own website better and exploit competitors’ weaknesses.

Analytical skills are also key in the content optimisation process. The specialist must assess which articles attract the most organic traffic and which need improvement in terms of keywords or text structure. Such analysis makes it possible to increase the effectiveness of SEO activities and achieve better results in search results.

1. 01Keyword cannibalisationDescribe the situation, apply content consolidation.

Questions about the candidate’s skills and experience

During interviews for SEO-related roles, recruiters often focus on the candidate’s practical skills and experience. One of the key topics is keyword cannibalisation. The candidate may be asked to describe a situation in which they had to deal with this problem and to present the strategies they used – e.g. content consolidation or changes to the site structure.

Another important area is content optimisation analysis compared with the competition. Questions may concern methods of researching competitor websites, such as analysing keyword density, link quality or the use of headings. It is worth showing that you can interpret data and suggest specific actions aimed at improving site visibility.

Experience in link building also often comes up in interviews. Recruiters may ask about strategies for acquiring valuable backlinks, working with influencers or using tools such as Ahrefs or SEMrush to analyse link profiles. It is also important to present examples of campaigns that delivered real results – e.g. growth in organic traffic or an improvement in the site’s rankings.

Soft skills are also important, such as teamwork and managing SEO projects. The candidate may be asked about collaboration with other departments (e.g. marketing or IT) and about ways of coordinating optimisation activities within larger initiatives.

Example questions may be:

• how do you react to a sudden drop in traffic from organic search,
• how do you assess the effectiveness of your link building activities,
• what tools do you use for competitor analysis.

The answers should be based on real experience and show both knowledge of SEO theory and a practical approach to solving problems.

What experience do you have with the problem of keyword cannibalisation?

Keyword cannibalisation is a common SEO issue that occurs when different pages within one website compete for the same keywords. To resolve it, I start with a detailed analysis of the pages competing for identical phrases. I then implement solutions such as:

• merging content,
• optimising for different keywords,
• changing the internal linking structure.

For example, while working on one project, I noticed that two subpages were competing for the phrase “local SEO“. After analysing it, I combined both pieces of content into one more valuable page that better met users’ needs. I also adjusted the anchor texts in internal links to distribute traffic more evenly across the subpages.

In another case, I focused on keyword diversification. Rather than concentrating on one main phrase, I concentrated on long tails (long-tail keywords). This strategy not only reduced competition between pages, but also increased their visibility in search results.

To detect cannibalisation, I use tools such as Google Search Console and Ahrefs. They allow me to track page rankings and analyse their mutual impact on rankings. Regular monitoring of this data is crucial for effective SEO management and avoiding the negative consequences associated with keyword cannibalisation.

2. 02Analyse impactAdjusting strategy
3. 03Suggest actionsConcrete response

In your answer, it is worth showing that you can analyse the impact of these changes and flexibly implement specific optimisation actions, e.g. for Core Web Vitals.

How do you assess the level of content optimisation compared with the competition?

To assess how well our content performs against the competition, I carry out a detailed analysis covering several key areas:

• first, I look at the quality and length of the texts on competitors’ pages, checking whether they are valuable for the audience, contain relevant keywords and have a logical structure, e.g. using H1-H3 headings,
• the next step is analysing user engagement metrics, such as time spent on the page or bounce rate, using tools such as Google Analytics, to compare these metrics with competitors’ data,
• an important element is keyword research, thanks to tools such as Ahrefs and SEMrush, which allow you to check which phrases competitors use and what positions they hold in search results,
• I also do not skip backlink analysis, examining the competitors’ link profile to understand which pages link to their content and what impact on SEO this has,
• finally, I compare technical aspects of the site, such as loading speed or responsiveness, using tools such as Google PageSpeed Insights, to assess these parameters and identify areas requiring optimisation.

A comprehensive assessment of the level of content optimisation includes analysing text quality, engagement metrics and the site’s technical aspects. This makes it possible to compete effectively with other websites and increase visibility in search results.

What experience do you have in effective link building?

Effective link building is based on a range of strategies whose main aim is to acquire valuable links from reliable sources. One of the most effective ways is creating high-quality content that attracts natural links. For example, publishing unique articles, industry reports or infographics often leads to them being shared by other users.

Another effective method is guest blogging, i.e. writing articles on partner sites or influencers’ websites in a given field. This makes it possible to gain backlinks from websites with high authority, which translates into a better position for the site in search results. However, it is crucial that the published materials are valuable and meet the audience’s needs.

It is also worth investing time in building relationships with influencers and industry experts. Working with well-established individuals can result in links from their websites or social profiles.

However, you should avoid Black hat SEO practices, such as buying links or adding large numbers of links on low-quality sites. Such actions can result in penalties from Google and a drop in the site’s visibility. Instead, it is better to focus on ethical White hat SEO methods, which bring lasting benefits.

To monitor the results of your actions, it is worth using tools such as Ahrefs or SEMrush. They allow you to analyse the site’s link profile, track new backlinks and assess their quality in terms of domain authority (DA) and page authority (PA). Regular data analysis makes it possible to adjust the strategy and achieve better results in SEO.

An example of an effective campaign was securing more than 50 high-quality backlinks for one client through cooperation with industry bloggers and publishing valuable educational content. The result was a 30% increase in organic traffic within three months and improved rankings for key phrases.

Effective link building requires combining various strategies based on creating valuable content and building relationships with authorities in the industry. The key is to monitor results regularly and adapt activities to the current needs of the site and changes in Google’s algorithms.

Technical questions in SEO interviews

During interviews for SEO roles, technical questions are used to assess a candidate’s practical skills in website optimisation. Recruiters often cover topics related to indexing, meta tags, HTTP response codes and other factors affecting a site’s visibility in search results.

Indexing pages in Google is one of the most important issues. A candidate may be asked to explain how to check whether a page has been indexed. This can be done, for example, by using the “site:” operator in search or by analysing reports in Google Search Console. It is also worth knowing methods that speed up the indexing of new subpages, such as submitting them via the Google URL Inspection Tool or optimising the sitemap.

Another common topic is HTTP response codes. A candidate should know which code to use for a permanently removed subpage (e.g. 410 Gone) and understand the difference between a permanent redirect (301) and a temporary one (302). This knowledge is crucial for maintaining a consistent site structure and avoiding problems related to duplicate content.

Recruiters may also ask about the use of the noindex meta tag, particularly in the context of categories and tags. The candidate should explain that this meta tag is used to block the indexing of pages that have low value for both users and search engines. This helps avoid problems with keyword cannibalisation.

Another important issue is the rel=’ugc’ attribute, which is used for user-generated links, for example in comments. Its main purpose is to inform Google that the link was not added by the site owner, which may affect the assessment of the link profile’s quality.

Technical questions often also cover topics related to Core Web Vitals, i.e. the key site performance metrics (LCP, FID, CLS). A candidate should know ways to optimise these parameters and tools for monitoring them, such as Lighthouse or PageSpeed Insights.

Example questions may include:

• how will you check the indexing status of a page,
• which methods speed up the indexing of new subpages,
• which HTTP code will you use for a permanently removed subpage,
• what is the purpose of the noindex meta tag,
• what is the rel=’ugc’ attribute used for.

The answers should be specific and based on real examples from the candidate’s professional experience. This shows not only knowledge of SEO theory, but also the ability to practically solve technical problems related to website optimisation.

How to check whether a page is indexed in Google?

To check whether your site is visible in Google, you can use a few simple techniques. One of the most commonly used methods is the “site:” operator. Simply enter the phrase “site:domainname.pl” (e.g. “site:yourwebsite.pl”) into the search engine to see which subpages have already been included in the index. No results may suggest indexing issues, which often result from blocking access for bots via the robots.txt file or applying the noindex meta tag.

Another useful tool is Google Search Console. After adding the site to this system, you can analyse indexing reports and identify potential errors. In the “Indexing” section, you will find data on the number of pages submitted to the index and those that actually appeared there.

It is also worth using the Google URL Inspection Tool, available in Google Search Console. This tool offers a detailed view of a specific page’s status – whether it has been indexed, what issues may exist and whether it meets Google’s technical requirements.

If a page does not appear in the results despite the absence of technical errors, make sure it has not been excluded by directives in the robots.txt file or the noindex meta tag. Regularly checking indexing status is a key part of maintaining a site’s visibility and responding quickly to any difficulties.

What methods speed up the indexing of new subpages?

To speed up the indexing of new subpages, it is worth using several proven techniques. One of the most effective methods is submitting the page via the Google URL Inspection Tool, available in Google Search Console. This allows you to manually submit the URL for indexing, which significantly shortens the waiting time for the page to appear in search results.

Another key element is optimising the sitemap. This XML file contains a list of all subpages that should be included in Google’s index. Submitting it to Google Search Console makes it easier for search engine crawlers to quickly find new content.

We should also not forget about internal linking. Adding links to a new subpage from other parts of the site not only increases its visibility for users, but also signals to Google bots that the page is valuable and deserves to be indexed.

It is also worth considering promoting content on social media. Sharing a new subpage on platforms such as Facebook, LinkedIn or Twitter can attract the attention of both users and indexing bots.

Additionally, it is recommended to regularly monitor indexing status using Google Search Console. This makes it possible to quickly detect and fix any technical issues, such as blocks preventing crawler access or incorrect use of the noindex meta tag.

By using these methods, you can significantly speed up the indexing process for new subpages and improve their visibility in search results.

Which HTTP code should be used for a permanently removed subpage?

To permanently remove a subpage, it is worth using the HTTP code 410 (Gone). This status informs search engines that the page has been permanently removed and will no longer be available. Unlike the 404 (Not Found) code, which suggests that the page may be restored in the future, 410 clearly indicates the irreversible removal of the resource.

Using this code speeds up the process of removing the page from the search engine index, which is particularly important when optimising the site structure. It helps avoid problems related to content duplication and signals to indexing bots not to try to revisit the given address. As a result, the indexing process becomes more efficient.

For example, when a company decides to remove an outdated product offer or archive blog posts, using code 410 allows better control over the site’s visibility in search results. Before implementing it, however, it is worth making sure that the page will no longer be needed and checking whether valuable links lead to it – both internal and external.

In the context of a job interview, the candidate should demonstrate knowledge of the differences between HTTP codes and the ability to choose the appropriate solution depending on the specific technical situation.

What is the use of the noindex meta tag in the context of categories and tags?

The noindex meta tag is primarily used to block the indexing of pages that may generate duplicate content, such as categories or tags. Such pages often struggle with keyword cannibalisation, when many subpages compete for the same keywords. By using noindex, you can prevent search engines from indexing low-value subpages, which could negatively affect the visibility of the entire site.

This meta tag tells search engine crawlers to skip the given page in search results. It is particularly useful in the case of category and tag pages, which often contain repeated content or are not very important from an SEO perspective. By blocking their indexing, you can focus on optimising key subpages that are more important for SEO.

For example, if a tag page presents only a list of articles without unique content, using noindex helps avoid problems related to duplicate content (duplicate content). This way, Google bots do not waste time analysing low-value pages, and the site’s resources are used more efficiently.

It is also worth noting that the noindex meta tag should be used together with the “follow” directive in the robots.txt file or the rel=”nofollow” attribute in internal links. This makes it possible to preserve the value of internal linking without the risk of indexing unnecessary subpages.

During a job interview, the candidate should demonstrate knowledge of the rules for using the noindex meta tag and the ability to explain its impact on site structure optimisation. It is also crucial to understand how, through the proper use of this tool, one can avoid problems related to keyword cannibalisation and improve overall site performance.

What is the use of the rel=’ugc’ attribute in links?

The `rel=’ugc’` attribute plays a key role in marking links coming from user-generated content, such as comments, forum posts or reviews. Its main purpose is to indicate to search engines that a given link was not added by the site owner, but by external users. This allows Google to assess the quality of a site’s backlink profile more accurately and avoid misinterpreting the value of such links.

This attribute is particularly important on sites with a large amount of user-generated content (UGC – User-Generated Content). For example, if comments containing links to other sites appear on a blog, using `rel=’ugc’` signals to indexing robots that those links are not part of the site owner’s official linking strategy.

It is worth noting that this attribute aligns with the principles of White hat SEO, i.e. ethical website optimisation practices. It helps avoid penalties from Google related to suspected ranking manipulation through low-quality links. This is particularly important in the context of counteracting Black hat SEO, i.e. unethical SEO methods.

For example, if an e-commerce site allows customers to add product reviews containing links to competing stores, using this attribute helps maintain transparency and avoid problems with Google’s algorithms.

During an interview for an SEO specialist role, a candidate should demonstrate knowledge of this attribute and the ability to explain its impact on assessing the quality of a site’s link profile. It is an important element of technical SEO knowledge.

Questions about updates and algorithm changes

Questions about updates and changes in Google’s algorithms often come up during interviews for SEO-related roles. Recruiters want to check whether the candidate keeps up to date with SEO trends and can flexibly adapt their strategies to the evolving requirements of search engines. Knowledge of key updates such as Google Core Updates or Page Experience Update is essential for every SEO specialist who wants to respond effectively to changes affecting site visibility.

One of the most frequently asked questions is: “How do you respond to Google algorithm updates?”. In your answer, it is worth showing that you can analyse the impact of these changes on SEO and propose specific actions. For example, after the introduction of Core Web Vitals, the focus should be on optimising performance metrics such as LCP (Largest Contentful Paint), FID (First Input Delay) or CLS (Cumulative Layout Shift).

Recruiters often also raise the topic of ranking factors, which may be modified with new updates. The candidate may be asked to discuss the key elements of their SEO strategy and how they monitor their impact on the site’s rankings. It is worth mentioning analytical tools such as Google Search Console or Ahrefs, which are invaluable for tracking site visibility.

Another important issue is experience in dealing with drops in organic traffic caused by algorithm changes. For example, after an update related to content quality (Quality Updates), a specialist should know how to carry out a content audit and improve materials with low value for users.

No less important is anticipating future trends and preparing SEO strategies in advance. The candidate may be asked to describe how they plan optimisation activities in the context of upcoming changes. An example might be adapting a site to the growing importance of user experience (UX) and mobile technologies.

What are Core Web Vitals?

Core Web Vitals are three key metrics that Google uses to assess the quality of a user’s experience on a website. They include:

• Largest Contentful Paint (LCP) – measures how quickly the largest visible element on the page loads. To ensure a smooth experience, this time should not exceed 2.5 seconds,
• First Input Delay (FID) – determines the delay in the page’s response to the user’s first interactions, such as a click or typing text. A value below 100 milliseconds guarantees a fast response,
• Cumulative Layout Shift (CLS) – assesses the stability of the page layout by detecting unexpected shifts in elements during loading. The optimal value is less than 0.1.

These metrics play an important role in SEO, as they directly affect a site’s position in search results and visitors’ satisfaction. Google is constantly refining its algorithms to better assess sites against these parameters, which is why their optimisation is crucial for maintaining competitiveness.

To track these metrics, it is worth using tools such as Google Search Console, Lighthouse or PageSpeed Insights. Regular analysis makes it possible to identify issues and introduce technical improvements that translate into better visibility in search results.

Core Web Vitals optimisation is not just an SEO matter – it is also a way to improve user experience. This makes your site faster and more user-friendly for visitors, which can translate into higher engagement and conversions.
