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.
28. Which SEO tools do you regularly use?
You will likely have tools you’re familiar with, and you’ll want to talk about those. If you don’t yet have much of a toolbox because you’re new to SEO, check out the multiple webmaster tools Google offers, as well as the tools offered by Moz, SEMRUSH, AHREF.
29. 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 is narrower so it’s targeted and has good search volume, but is not highly competitive.
30. 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 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.
31. What are backlinks?
A backlink is what we call the links into a website from an external source, as mentioned in link building.

In general, a 301 redirect is the best way to redirect a page so you don’t lose any SEO value that has been accumulated.
34. 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).
35. 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.
36. 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.
37. 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.
38. 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.
39. 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.
40. What is keyword stemming and why does it matter?
Keyword stemming is adding to the stem of a word. For example, if the word interview was your stem, variations could be interviewing, interviewer, interviews. Using keyword stemming helps you to use more relevant keywords on a webpage without keyword stuffing or ending up with content that reads poorly.
41. What is the most important thing to look for when doing keyword research?
This is a subjective question! People new to SEO tend to focus on popular keywords without considering the competitiveness of that keyword, so that’s something you could mention. Search volume and relevancy are other factors you might discuss.
42. What is a canonical issue?
A canonical issue happens when you seem to have duplicate content. (Google penalizes for duplicate content.) This might happen if you have different versions of a URL pointing to the same webpage, for example, http://exampleURL.com and http://www.exampleURL.com.
43. How have you dealt with link penalties?
We hope you haven’t had any link penalties slapped on you by Google due to your SEO efforts, and you might want to make that clear to your interviewer! Then address the steps you’ve taken to find bad links, and either fix them if you can or disavow those you can’t.
44. What are rich snippets?
Rich snippets are the featured text that appears at the top of the organic search results, in a box, and sometimes with an image. Webmasters can use structured data to mark up content so that search engines can easily identify the type of content and deliver it as a rich snippet. Rich snippets are not part of SEO, but if used, they can deliver better results on the SERPs.
45. What is Google Autocomplete?
Google Autocomplete is a function in Google and other search engines. When a user starts typing in the search box, the Google autocomplete function gives you a list of options to complete your search.

More fresh content you produce, more frequent your website will be crawled from search engines.

51. Difference between DA and PA.
DA is Domain Authority. It explains the authority of your entire website. The higher the DA, the higher the possibility of ranking. But, DA is one of the hundreds of ranking factors.
PA is Page Authority. It explains the authority of a specific page, based on the backlink, social sharing, etc.
52. What is White Hat SEO?
One of the most common questions in any SEO interview question and answers guide. White Hat SEO is a process of improving your search engine rank following the guidelines of search engines without compromising on your methods.
White Hat SEO doesn’t involve manipulating search engines with shady methods but instead involves building search engine-friendly websites and user experiences. White hat involves creating quality content that provides value to the visitors and helps them to earn links instead of building backlinks.
53. What is Black Hat SEO?
Black Hat SEO is a process of trying to manipulate search engine algorithms to improve the search engine ranking. It violates search engines’ guidelines. Black Hate SEOs practice the methods to get immediate results instead of building a website with users in mind.
There are so many Black Hat methods they utilize and search engines identify and offer penalties if get caught. Black Hat methods might be helpful in the short term but if you are planning for the long term, black hat definitely is not the solution. If your site gets penalized, it takes so much time and effort to remove it.
54. What is a PBN?
Private Blog Network is a website built on dropped or auctioned domains. Some black hat SEOs build them to link to their important website and transfer authority.
Google is against this method as it can uplift a spammy website so they are most often hidden from search engines.

56. What is a No-follow link?
Again, one of the important SEO interview questions. No-follow is another type of backlink where webmasters can tell search engines not to follow the specific link.
Well, it doesn’t guarantee Google not to follow the links. Businesses use the Nofollow links when they link social media sites or any other third-party sites and don’t want to pass their link juice to those websites.
57. What is the difference between do-follow and no-follow links?
A Do-follow link passes the link juice from one domain to another and the no-follow link doesn’t pass the link juice.
A Do-follow link is more valuable in terms of SEO and No-follow links are less valuable.

Keyword Density is the percentage of times a keyword or phrase appears on a specific web page. When the keyword density is far higher than the recommended level, it might trigger search engines to think it’s keyword stuffing. So, we need to make sure the keyword density is not too high for any primary or secondary search phrases.
For example, if a keyword appears 5 times in an article of 200 words, the density would be 2.5%. There is no ideal keyword density but 3-4% is considered as best practice for SEO.
62. What is Keyword Stuffing?
Keyword stuffing is a black hat SEO method which increases the number of keyword density to a far higher range in order to rank for potential keywords. After the panda update, it’s not recommended to keyword stuff to manipulate search engines and should be avoided at all costs.
63. What is Keyword Prominence?
Keyword Prominence tells where your keyword is located in a web page. For example, in a blog section, it is better to have your keyword in the article, especially first and last paragraph.

66. What is long tail keyword?
Long tail keywords are phrases which have more than 4 words and very specific in nature.

Outbound links are links that links your website to another website.
Having too many outbound links might hurt your SEO as they pass link juice from your domain to another domains. It is recommended to have no-follow links to outbound links to avoid passing on authority.
