SEO Fundamentals (Terms 1–10)
1. SEO (Search Engine Optimization)
SEO is the process of improving a website so it appears higher in unpaid search results on Google, Bing, and other search engines. It combines technical fixes, content creation, and link building to bring more relevant visitors to a website without paying for ads.
2. Search Engine
A search engine is software that crawls the internet, stores web pages in a database, and shows the most relevant results when a user types a query. Google, Bing, Yahoo, DuckDuckGo, and Yandex are the most common examples used worldwide.
3. SERP (Search Engine Results Page)
SERP is the page Google shows after a user enters a search query. It includes organic results, paid ads, featured snippets, image packs, video carousels, AI Overviews, and the local map pack. Every SEO professional studies SERPs daily to plan content strategy.
4. Keyword
A keyword is the word or phrase a user types into a search engine. For SEO, keywords are the bridge between what people search for and the content you create. Choosing the right keywords decides who visits your website and why.
5. Search Intent
Search intent is the reason behind a user’s search. It usually falls into four types — informational (to learn), navigational (to reach a specific site), commercial (to compare options), and transactional (to buy). Matching content to intent is one of the strongest ranking factors today.
6. Organic Traffic
Organic traffic refers to visitors who land on your website by clicking unpaid search results. Unlike paid ads, this traffic is earned through quality content and SEO. High organic traffic is usually the main goal of every SEO campaign.
7. Ranking
Ranking is the position your webpage holds on a search engine results page for a particular keyword. Position 1 gets the most clicks, and the goal of SEO is to push important pages as close to the top as possible.
8. Impressions
An impression is counted every time your webpage appears in front of a user on the SERP — whether they click it or not. Impressions show how often Google is putting your page in front of searchers and indicate keyword visibility.
9. Clicks
A click is recorded when a user actually clicks on your webpage from the search results. Clicks measure how attractive your title and meta description are. More impressions with low clicks usually mean weak titles or wrong keyword targeting.
10. CTR (Click-Through Rate)
CTR is the percentage of impressions that turn into clicks. Formula: (Clicks ÷ Impressions) × 100. For example, 50 clicks on 1,000 impressions equals a 5% CTR. Higher CTR signals to Google that your result is highly relevant to users.
Keyword Research Terms (11–18)
11. Search Volume
Search volume is the average number of times a keyword is searched in a specific country per month. For example, “digital marketing course in Mysore” may have 1,300 monthly searches in India. Higher volume usually means more opportunity but also more competition.
12. Keyword Difficulty
Keyword difficulty (KD) is a score from 0 to 100 that estimates how hard it is to rank on Google’s first page for a keyword. Lower KD means easier ranking. Tools like Ahrefs, Semrush, and Ubersuggest calculate it based on competitor backlinks and authority.
13. Long-Tail Keyword
A long-tail keyword is a longer, more specific phrase with lower search volume but higher buying intent. Example: “affordable digital marketing course in Mysore for beginners.” These keywords are easier to rank for and usually convert better than generic short-tail keywords.
14. Short-Tail Keyword
A short-tail keyword is a broad, one or two-word phrase with very high search volume — for example, “SEO” or “digital marketing.” They drive massive traffic but are extremely competitive and have low conversion rates because the search intent is unclear.
15. Primary Keyword
The primary keyword is the main keyword a page is optimized to rank for. It appears in the title tag, H1, URL slug, meta description, and naturally throughout the content. Every page should target one clear primary keyword to avoid confusion.
16. Secondary Keywords
Secondary keywords are supporting keywords related to the primary keyword. They add context and help the page rank for variations and related searches. Including 3–5 secondary keywords naturally in subheadings strengthens topical relevance without keyword stuffing.
17. Keyword Stuffing
Keyword stuffing is the bad practice of forcing a keyword into the content unnaturally, hoping to rank higher. It hurts readability and is penalized by Google. Modern SEO focuses on natural, contextual use of keywords — not repetition for the sake of it.
18. Keyword Cannibalization
Keyword cannibalization happens when two or more pages on the same website target the same keyword. Google gets confused about which page to rank, splitting authority and hurting both. Fix it by merging pages, redirecting, or re-optimizing for different keywords.
On-Page SEO Terms (19–28)
19. Title Tag / Meta Title
The title tag is the clickable headline shown on the SERP and in the browser tab. It should be 50–60 characters, include the primary keyword near the start, and be compelling enough to earn the click. It is the single most important on-page SEO element.
20. Meta Description
The meta description is the short summary shown below the title tag on the SERP. It should be 145–160 characters, include the primary keyword, and convince the user to click. While it doesn’t directly affect rankings, it heavily influences click-through rate.
21. URL Slug
The URL slug is the part of the web address that comes after the domain — for example, “/seo-interview-terminologies/.” A good slug is short, lowercase, includes the primary keyword, and uses hyphens between words instead of underscores or spaces.
22. Heading Tags
Heading tags (H1 to H6) structure your content from most important to least important. H1 is the main title of the page, H2s are major sections, and H3s are subsections. Proper heading hierarchy helps both readers and search engines understand the page structure.
23. H1 Tag
The H1 tag is the main heading of a webpage. There should be only one H1 per page, and it must clearly describe what the page is about while including the primary keyword. It is one of the strongest on-page relevance signals.
24. Alt Text
Alt text is the descriptive text added to an image so screen readers and search engines understand what the image shows. Good alt text improves accessibility, helps images rank in Google Image Search, and supports overall on-page SEO when written naturally.
25. Internal Link
An internal link is a hyperlink from one page on your website to another page on the same website. It helps users navigate, distributes page authority across the site, and helps Google understand your site structure and the relationship between pages.
26. External Link
An external link is a hyperlink that points from your website to a page on a different domain. Linking out to credible, authoritative sources signals quality to Google and adds trust and value to your content for readers.
27. Anchor Text
Anchor text is the visible, clickable words of a hyperlink. For example, in “learn more about SEO training in Mysuru,” the underlined phrase is the anchor text. It tells both users and Google what the linked page is about.
28. Content Optimization
Content optimization is the process of improving existing or new content so it ranks better, reads easier, and answers user intent more completely. It covers keyword placement, formatting, readability, internal links, images, schema, and updating outdated information.
Technical SEO Terms (29–40)
29. Crawling
Crawling is the process by which search engine bots discover web pages by following links from one page to another. If a page isn’t crawled, it cannot appear in search results. Internal links and sitemaps help bots crawl your site efficiently.
30. Indexing
Indexing is the step after crawling, where Google stores your page in its database so it can be served as a search result. Only indexed pages can rank. You can check a page’s index status using Google Search Console’s URL Inspection tool.
31. Googlebot
Googlebot is Google’s web crawler — the software that visits websites, reads their content, and sends it back to Google for indexing. It comes in two main versions: Googlebot Desktop and Googlebot Smartphone, with mobile-first indexing being the default since 2019.
32. Robots.txt
Robots.txt is a plain text file placed in the root of your website that tells search engine bots which pages or folders they can or cannot crawl. It’s used to block admin pages, staging sites, or duplicate URLs from being indexed.
33. XML Sitemap
An XML sitemap is a file that lists all the important URLs on your website that you want search engines to crawl and index. Submitting it to Google Search Console helps Google discover new and updated pages faster, especially on large sites.
34. Canonical Tag
A canonical tag (rel=”canonical”) tells Google which version of a duplicate or similar page should be treated as the main one. It prevents duplicate content issues and consolidates ranking signals to a single preferred URL, especially on e-commerce sites.
35. 404 Error
A 404 error means the requested page is not found on the server — usually because it was deleted, moved, or the URL was typed incorrectly. Too many 404 errors hurt user experience and waste Google’s crawl budget on your website.
36. 301 Redirect
A 301 redirect is a permanent redirect from one URL to another. It passes nearly all of the original page’s SEO value to the new URL. Use 301s when you change a page’s URL, merge content, or migrate to a new domain.
37. Page Speed
Page speed is how quickly a webpage loads in a browser. Faster pages rank better and convert more visitors. Common ways to improve page speed include compressing images, enabling caching, using a CDN, and reducing unused JavaScript and CSS.
38. Mobile Friendliness
Mobile friendliness means a website works well on smartphones — readable fonts, tappable buttons, responsive layouts, no horizontal scrolling. Since Google uses mobile-first indexing, a site that isn’t mobile-friendly will struggle to rank in 2026 and beyond.
39. Core Web Vitals
Core Web Vitals are Google’s user-experience metrics: LCP (Largest Contentful Paint — loading), INP (Interaction to Next Paint — interactivity), and CLS (Cumulative Layout Shift — visual stability). They are confirmed ranking factors and measured per page in Search Console.
40. HTTPS / SSL
HTTPS is the secure version of HTTP, made possible by an SSL certificate. It encrypts data between the browser and the website, protecting user information. HTTPS is a confirmed (lightweight) Google ranking factor and a basic trust signal for every website.
Off-Page SEO and Backlinks (41–48)
41. Backlink
A backlink is a link from another website that points to your website. Google treats backlinks as votes of confidence — the more high-quality backlinks you earn, the more authority and trust your site gains. Backlinks remain one of the strongest ranking factors.
42. Link Building
Link building is the practice of actively earning backlinks from other websites through outreach, guest posts, digital PR, partnerships, and creating link-worthy content. Quality and relevance matter far more than quantity in modern link building.
43. Referring Domain
A referring domain is a unique website that links to your site. If a single website links to you 10 times, that’s still one referring domain. The number of unique referring domains is usually a stronger authority signal than the total number of backlinks.
44. Domain Authority (DA)
Domain Authority is a 0–100 score developed by Moz that predicts how well a website will rank on search engines. It’s based on backlinks, referring domains, and other signals. Note: DA is a third-party metric, not used directly by Google.
45. Dofollow Link
A dofollow link is the default type of link that passes SEO authority (link equity) from the linking page to the linked page. Dofollow backlinks from high-authority, relevant sites are the most valuable for improving search rankings.
46. Nofollow Link
A nofollow link includes a rel=”nofollow” attribute that tells search engines not to pass authority through the link. They’re common on social media, blog comments, and paid placements. Nofollow links still bring referral traffic and can indirectly support SEO.
47. Link Juice / Link Equity
Link juice (also called link equity) is the SEO value a linked page passes to another page through a hyperlink. Dofollow links pass juice; nofollow links generally don’t. A page can pass more juice when it has high authority and few outbound links.
48. Toxic Backlink
A toxic backlink is a low-quality or spammy link that can harm your website’s rankings or trigger a Google penalty. They usually come from PBNs, link farms, irrelevant sites, or adult/gambling websites. Use Google’s Disavow Tool to neutralize them.
Local SEO Terms (49–54)
49. Local SEO
Local SEO is the process of optimizing a business to appear in location-based search results — for example, “best digital marketing institute in Mysuru.” It’s critical for clinics, restaurants, schools, real estate, and any service that serves a specific city or area.
50. Google Business Profile (GBP)
Google Business Profile (formerly Google My Business) is a free Google tool that lets businesses manage how they appear on Google Search and Maps. It includes business name, address, phone, hours, photos, services, and reviews — the foundation of local SEO.
51. NAP (Name, Address, Phone)
NAP stands for Name, Address, and Phone number. Keeping NAP details identical across your website, Google Business Profile, and all directories is a key local SEO ranking signal. Inconsistent NAP information confuses Google and lowers local search visibility.
52. Local Citation
A local citation is any online mention of your business’s NAP details on directories like JustDial, Sulekha, Yellow Pages, IndiaMART, Yelp, or industry-specific listings. Consistent citations across trusted directories build trust and improve local pack rankings.
53. Reviews and Ratings
Reviews and star ratings on your Google Business Profile influence both local rankings and click decisions. A higher quantity of genuine, recent, and positive reviews — combined with thoughtful owner responses — directly improves visibility in the local pack.
54. Map Pack / Local Pack
The map pack (also called the local pack or 3-pack) is the boxed section at the top of Google’s search results that displays a map and three local business listings. Ranking in the map pack is the goal of every local SEO campaign.
SEO Tools You Must Know (55–60)
55. Google Search Console (GSC)
Google Search Console is a free Google tool that shows how your website performs in Google Search. It reports impressions, clicks, average position, indexing issues, mobile usability, and Core Web Vitals. Every SEO professional uses it daily — non-negotiable.
56. Google Analytics / GA4
Google Analytics 4 (GA4) is Google’s free web analytics tool that tracks user behavior on your website — sessions, users, traffic sources, events, conversions, and engagement. SEOs use GA4 to measure how organic traffic actually performs after the click.
57. Google Keyword Planner
Google Keyword Planner is a free tool inside Google Ads that shows keyword ideas, average monthly search volume, and competition data. While built for advertisers, SEO professionals use it to validate keyword opportunities directly from Google’s own data.
58. Google Trends
Google Trends is a free Google tool that shows the relative popularity of search terms over time and across locations. SEOs use it to spot seasonal trends, rising topics, and regional interest — for example, when “GST course” demand spikes in India.
59. Screaming Frog
Screaming Frog SEO Spider is a desktop tool that crawls your website like Googlebot would. It audits broken links, missing meta tags, duplicate content, redirect chains, and more. It’s the industry standard for technical SEO audits and site migrations.
60. Rank Math / Yoast SEO
Rank Math and Yoast SEO are the two most popular WordPress SEO plugins. They help you optimize title tags, meta descriptions, schema markup, XML sitemaps, internal linking, and on-page SEO scoring — all without writing any code.
Content and Strategy Terms (61–66)
61. Thin Content
Thin content is a page with little or no useful information — usually too short, generic, or repetitive to satisfy search intent. Google’s algorithms (especially the Helpful Content System) routinely demote thin content from search results.
62. Duplicate Content
Duplicate content is identical or nearly identical content that appears on multiple URLs — either within your own website or across different domains. It confuses search engines about which version to rank and can dilute SEO value.
63. Content Gap
A content gap is a topic, question, or keyword your competitors cover but your website doesn’t. Identifying and filling content gaps helps capture missed traffic, strengthen topical authority, and serve user questions you currently don’t answer.
64. Content Audit
A content audit is a systematic review of every piece of content on your website to decide what to keep, update, merge, redirect, or delete. Audits help eliminate thin pages, fix decaying rankings, and improve overall site quality.
65. Topical Authority
Topical authority is the depth and breadth of expertise your website demonstrates on a specific subject. Sites that publish comprehensive, interlinked content covering every angle of a topic earn topical authority and rank for related keywords more easily.
66. E-E-A-T
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It’s part of Google’s Search Quality Rater Guidelines and is especially important for YMYL (Your Money or Your Life) topics like health, finance, and legal. Strong E-E-A-T signals improve ranking potential.
SEO Metrics and Reporting (67–72)
67. Average Position
Average position (shown in Google Search Console) is the average ranking of your webpage for a keyword across all impressions in a given period. Tracking changes in average position helps you measure whether your SEO efforts are moving you up or down.
68. Bounce Rate
Bounce rate is the percentage of users who land on your page and leave without any further interaction. Note: GA4 has shifted focus from bounce rate to engagement rate, but bounce rate still indicates whether your content satisfies search intent.
69. Engagement Rate
Engagement rate in GA4 is the percentage of sessions that lasted more than 10 seconds, had a conversion event, or had two or more pageviews. A higher engagement rate signals that visitors are finding your content useful and relevant.
70. Conversion Rate
Conversion rate is the percentage of visitors who complete a desired action — buying, filling a form, downloading a PDF, or booking a call. Formula: (Conversions ÷ Total Visitors) × 100. SEO traffic is only valuable when it converts.
71. Organic Sessions
Organic sessions are the visits to your website that originate from unpaid search results. In GA4, this is reported under the “Organic Search” channel. Growth in organic sessions month-over-month is the simplest health check for any SEO campaign.
72. Pageviews
A pageview is counted every time a page on your website is loaded or reloaded in a browser. Pageviews show which pages get the most attention. Combined with engagement and conversion data, they help prioritize which pages to optimize first.
How to Use These SEO Terms in Your Interview
Memorizing definitions is the starting line, not the finish line. Interviewers in 2026 are looking for candidates who can:
- Explain in plain English — if you can’t simplify it, you don’t understand it.
- Give a real example — instead of just defining “long-tail keyword,” cite one (“digital marketing course in Mysore for working professionals”).
- Connect terms — show how crawling leads to indexing, which leads to ranking, which leads to impressions, clicks, and CTR.
- Show tool fluency — mention Google Search Console, GA4, Ahrefs/Semrush, or Screaming Frog when relevant.
- Show curiosity about AI search — talk about AI Overviews, GEO (Generative Engine Optimization), and how SEO is evolving with ChatGPT, Perplexity, and Gemini.

How is technical SEO different from on-page SEO?
Technical SEO focuses on the backend — crawling, indexing, site speed, mobile friendliness, HTTPS, robots.txt, XML sitemap, canonical tags, and Core Web Vitals. On-page SEO focuses on content elements visible to users — titles, headings, body copy, images, and internal linking.
Is SEO a good career option in India in 2026?
Yes. SEO continues to be in strong demand across Indian agencies, SaaS startups, e-commerce brands, and in-house marketing teams. With the rise of GEO and AI search, skilled SEO professionals who understand both classic ranking and AI citation optimization are even more valuable.
How long does it take to learn SEO?
You can learn the fundamentals in 4–6 weeks with focused study. Becoming job-ready usually takes 3–4 months of practice on real websites. Becoming an expert who can manage multi-client campaigns and complex audits typically takes 1–2 years of consistent work.
What’s the difference between SEO and SEM?
SEO (Search Engine Optimization) is about earning unpaid, organic search visibility through content and technical improvements. SEM (Search Engine Marketing) is the broader umbrella that includes both SEO and paid search advertising like Google Ads. In many job descriptions, SEM specifically refers to paid search.
