Bookmark this page as your one-stop resource to master the terminology that powers search rankings.
Ad Impressions
An ad impression measures how many times your advertisement is displayed on a webpage whether or not it was clicked. It's a foundational metric in paid marketing and brand awareness campaigns.
Tip: High impressions with low clicks may indicate weak ad copy or targeting, so always track click-through rate (CTR) alongside impressions.
ADA Website Compliance
ADA compliance refers to making your website accessible to people with disabilities, in line with the Americans with Disabilities Act. This means implementing features like keyboard navigation, screen reader compatibility, alt text, and proper colour contrast.
Why It Matters: Besides being ethically important, an ADA-compliant site also improves user experience and can prevent legal risks. Accessibility can even positively impact SEO by enhancing site structure and usability.
AhrefsBot
AhrefsBot is the web crawler used by Ahrefs, one of the leading SEO tools. It scans websites to gather backlink data, keyword rankings, and site health information for its users.
SEO Insight: If you're seeing AhrefsBot in your logs, it means your site is being indexed for inclusion in Ahrefs’ backlink database — a good sign for visibility.
Alt Text (Alternative Text)
Alt text is a written description added to images in your HTML code. It serves two key roles: making content accessible for screen readers and helping search engines understand what an image is about.
SEO Tip: Properly optimised alt text boosts image search visibility and contributes to overall page relevance.
Anchor Text
Anchor text is the clickable text in a hyperlink — what users see and click on. Google uses anchor text as a ranking signal to determine the topic and intent of the linked page.
Best Practice: Use descriptive, relevant anchor text rather than vague terms like "click here."
Article Spinning
Article spinning involves rewriting an original article to create multiple "unique" versions often using automated tools. While tempting for content scaling, this tactic can result in low-quality or duplicate content.
Warning: Google may penalise spun content, so it's best to focus on originality and value rather than mass replication.
Article Syndication
Article syndication means republishing the same article on other websites often with attribution and a canonical tag pointing to the original source.
Why Use It: When done correctly, syndication can boost visibility and referral traffic, especially on high-authority platforms like Medium or LinkedIn.
Auto-Generated Content
This refers to content created automatically through software, code, or AI without human input. While it can speed up publishing, search engines are cautious of auto-generated text that lacks originality or adds no real value.
Balance It Right: AI tools can assist in brainstorming or drafting but human editing, relevance, and quality are essential for SEO success.
Algorithm
A set of complex rules used by search engines to determine the ranking of web pages based on many factors (e.g., relevance, quality, speed).
Algorithm Change
Updates made by search engines to improve search quality.
Types include:
- Algorithm Update: Tweak to an existing algorithm
- Refresh: Re-run using same rules
- New Algorithm: A completely new system (e.g., Google Panda, Penguin)
Alt Attribute (Alt Text)
Text used in HTML to describe images for screen readers and search engines. Also improves image SEO.
AMP (Accelerated Mobile Pages)
An open-source HTML framework designed to load content faster on mobile. Once a key factor in ranking news stories, AMP is no longer required for visibility in Google’s Top Stories.
Analytics
The collection and analysis of website data to improve performance. For example, Google Analytics helps track traffic, behaviour, and conversion rates.
Artificial Intelligence (AI)
Technology that mimics human intelligence. AI in SEO helps with content generation, user experience, and ranking analysis.
Authority
A measure of trust and credibility assigned by search engines, influenced by backlinks, content quality, and brand signals.
Author Authority
The credibility of a content creator. While not a direct ranking factor, it's important in YMYL niches (e.g., health, finance) for user trust.
B2B (Business-to-Business)
Marketing products or services to other businesses. In SEO, B2B strategies often involve longer buying cycles and high-value content.
B2C (Business-to-Consumer)
Selling directly to individual customers. In B2C SEO, content is more emotionally driven and buying cycles are typically shorter than B2B.
Backlink
A link from another website to your own.
Why It Matters: Backlinks act as a vote of confidence, boosting your site’s authority and search engine rankings. Also known as: Inbound Link
Baidu
China’s leading search engine, similar to Google in function but tailored for Chinese users and content.
Bing
Microsoft’s search engine, which also powers Yahoo search results. While it has less market share than Google, Bing SEO can be valuable for certain demographics.
Black Box
A system where input and output are visible, but the internal process is unknown. For example, Google’s ranking algorithm is a black box — we know what affects it, but not how it precisely works.
Black Hat SEO
Tactics that violate search engine guidelines in an attempt to manipulate rankings.
Examples: Keyword stuffing, cloaking, and link schemes.
Risky: These can result in manual penalties or deindexing.
Blog
A section of a website featuring regularly updated content, usually sorted in reverse chronological order.
SEO Tip: A blog helps improve topical authority, drive long-tail traffic, and support internal linking.
Bounce Rate
The percentage of users who leave your site after viewing only one page.
While not a direct ranking factor, a high bounce rate might suggest poor UX or irrelevant content.
Bot
A software application that runs automated tasks. In SEO, bots (like Googlebot) are responsible for crawling and indexing websites.
Branded Keyword
Search queries that include your brand name or variations of it. For instance, “Nike shoes”, “Courses Buddy Courses”, or “Moz SEO tools”
Breadcrumb
A navigational aid showing the user’s location within a website’s hierarchy.
Example: Home > Blog > SEO Tips > Link Building
Breadcrumbs improve UX and can appear in Google search results.
Broken Link
A hyperlink that leads to a missing or deleted page, resulting in a 404 error.
Too many broken links can hurt user experience and crawlability.
Fix by updating or redirecting them.
Canonical URL
A tag (rel="canonical") that tells search engines which version of a page is the preferred one.
Useful for managing duplicate content and consolidating ranking signals.
Canonicalisation
The process of selecting the best URL when there are several choices for a single page.
Example:
- https://example.com
- https://www.example.com
- https://example.com/index.html
Canonicalisation ensures Google doesn’t index multiple versions of the same content.
Click-Through Rate (CTR)
The percentage of people who see your link (impressions) and click it.
Formula: Clicks ÷ Impressions × 100
High CTR signals relevance and may impact rankings, especially in paid ads.
Cloaking
A black hat SEO technique where the content presented to the search engine is different from what’s shown to users.
This violates Google’s guidelines and can lead to penalties.
CMS (Content Management System)
Software that helps you build and manage a website without needing to code.
Popular CMS platforms: WordPress, Shopify, Wix, Joomla
WordPress is often preferred for SEO due to flexibility and plugin support.
Content Audit

Helps you:
- Identify thin or outdated content
- Find internal linking gaps
- Optimise high-potential pages
Content Marketing
A strategic approach to creating and distributing valuable, relevant content to attract and engage a target audience ultimately driving profitable action.
Core Web Vitals
A set of performance metrics from Google focused on user experience:
- Largest Contentful Paint (LCP) – Loading performance
- First Input Delay (FID) – Interactivity
- Cumulative Layout Shift (CLS) – Visual stability
Meeting these metrics is crucial for ranking in Google’s Page Experience update.
Crawler (Bot/Spider)
Automated software used by search engines to browse the internet and index pages. For example, Googlebot is Google’s crawler.
Crawl Budget
The number of pages a search engine bot is willing to crawl on your site during a given timeframe. Large or frequently updated sites need to manage crawl budget effectively through clean architecture, internal linking, and sitemap optimisation.
Crawl Error
When a bot fails to access a page on your site.
Types:
- DNS errors
- Server errors (5xx)
- 404 Not Found
Monitor these using Google Search Console.
CTR Manipulation
Tactics to artificially increase your click-through rate. Often considered spammy or manipulative if using bots or paid click farms.
DA (Domain Authority)
A metric by Moz (scale: 1–100) that predicts how well a domain might rank in search engines.
Note: It’s not used by Google, but it's helpful for comparing websites in your niche.
Deindexed
When a page or website is removed from Google’s index and no longer appears in search results.
Causes include:
- Manual penalties
- Violating Google’s quality guidelines
- Use of noindex tags
- Technical issues like broken sitemaps
Deep Linking
Creating links that point to pages within your website rather than just the homepage. For example, linking directly to a blog post or product page.
This strengthens internal SEO and improves user navigation.
Directory Links
Backlinks from online business directories.
Good: High-quality, niche-relevant directories (e.g., Yelp, GBP, Clutch)
Bad: Low-quality or spammy directories — these violate Google’s guidelines and may trigger penalties.
Disavow Tool
A tool in Google Search Console that lets you ask Google not to consider certain backlinks when assessing your site. Only use this if you’ve received unnatural link warnings or suspect a negative SEO attack.
Dofollow Link
A regular link that passes PageRank (ranking power) from one site to another.
Note: "Dofollow" is not an official tag. It’s just the default link behaviour unless marked as "nofollow".
Duplicate Content
Blocks of content that are exactly or significantly similar across different URLs.
This can confuse search engines and may dilute rankings.
Note: Use canonical tags or 301 redirects to handle duplicates properly.
Dynamic Content
Content on a webpage that changes based on user behaviour, preferences, or device.
Examples:
- Location-based content
- Recently viewed products
You can improve UX but must be crawlable for SEO purposes.
Dwell Time
The amount of time a user spends on a page before returning to the SERP. While not a confirmed ranking factor, longer dwell time can signal user satisfaction.
DuckDuckGo
A privacy-focused search engine that doesn’t track user data. While its global market share is small, it’s growing in popularity among privacy-conscious users.
E-A-T (Expertise, Authoritativeness, Trustworthiness)
A framework from Google’s Quality Rater Guidelines to assess content quality. While not a direct ranking factor, E-A-T influences how Google evaluates content, especially in YMYL (Your Money or Your Life) niches like health and finance.
To improve E-A-T:
- Show author credentials
- Use reputable sources
- Secure your site (HTTPS)
- Build positive brand mentions
Editorial Links
Unpaid, naturally earned backlinks placed by other websites because your content is valuable. These are highly trusted by search engines and a strong signal of authority.
For example, a journalist linking to your blog post in a news article.
Engagement Metrics

Key metrics include:
- Bounce rate
- Pages per session
- Time on site
- Scroll depth
These give insights into content quality and user satisfaction.

Evergreen Content
Content that remains relevant and valuable over time.
Examples:
- “How-to” guides
- FAQs
- Tutorials
Evergreen content supports long-term SEO, attracts backlinks, and compounds organic traffic growth.
External Link
A link on your site that points to a different domain.
Best practice: Link to high-quality, relevant sources to improve user experience and signal trust to search engines.
Exact Match Domain (EMD)
A domain name that exactly matches a search query (e.g., bestlaptops2025.com).
Google used to favour EMDs, but they now offer no SEO advantage on their own and can even look spammy without quality content.
Exit Rate
The percentage of users who leave your website from a specific page. Different from bounce rate. Exit rate counts any page exit, not just single-page visits.
Excerpts
Short summaries of content, often used in blog archives, category pages, or SERPs.
They help improve click-through rates and guide users to relevant pages.
Featured Snippet
A highlighted box at the top of Google’s SERP, providing a direct answer to a user’s query. It often includes text, lists, tables, or videos. Also called “Position 0” — can drive significant organic traffic.

- H2-H6: Subheadings
These help search engines and users understand the topic structure of your content. And always use header tags logically and include relevant keywords where appropriate.
Heading Structure
The logical organisation of headings on a web page using header tags. A clean heading structure improves readability, accessibility, and SEO by guiding both readers and search engines through your content.
Hidden Content
Content that is not immediately visible to users (e.g., in tabs or dropdowns). Google can index hidden content, but visible content tends to carry more weight for ranking.
Hilltop Algorithm
A component of Google’s ranking system that assesses the relevance and authority of a page based on expert or "hub" pages that link to it. Especially important for informational searches.
Hits
A general server metric measuring the number of file requests from a site. Not a reliable measure of user engagement or traffic. It uses sessions or users in Google Analytics instead.

"How long does SEO take to work?"
Optimising content to answer these questions can improve your visibility and click-through rate.
Personalisation
Search engines customise results based on the user’s:
- Search history
- Location

Sources of qualified traffic:
- Targeted keywords
- High-quality backlinks
- Relevant content and offers
Focus your SEO and content efforts on attracting qualified, not just more traffic.

Search engines interpret queries using intent and match them with the most relevant content. Understanding search intent (informational, navigational, transactional) helps improve keyword targeting.
Query Deserves Freshness (QDF)
A part of Google’s algorithm that gives priority to fresh content for time-sensitive or trending topics.
Examples:
- “Olympics 2025 schedule”

Ranking Factors
The signals and criteria search engines use to decide how to rank pages.
Common factors include:

- Mobile-friendliness
- Keyword relevance
- Content quality
Google's algorithm uses hundreds of seo factors. Prioritise those with the highest SEO impact.
Reach
The total number of unique people who see your content, ad, or page.
Unlike impressions (which may count multiple views by the same user), reach measures individual exposure.
In digital marketing, increasing your reach can lead to greater brand awareness and traffic.
Redirect
A way to send both users and search engines from one URL to another.
- 301 Redirect: Permanent redirect; passes nearly all link equity
- 302 Redirect: Temporary redirect; used when a page will come back
Remember: Always use redirects wisely to avoid losing SEO value or creating redirect chains.
Referral Traffic
Visitors who land on your site by clicking a link from another website. For example, someone visits your blog from a link on a guest post or news article.
Tip: Track referral traffic in Google Analytics under Source/Medium to assess your off-page efforts.
Rel Canonical Tag
An HTML tag used to tell search engines which version of a URL is the master copy. They are useful for avoiding duplicate content issues when the same content exists across multiple URLs.
Tip: Place rel="canonical" in your page header to consolidate ranking signals.
Relevance
How well your content matches the user’s query and intent. Search engines use keyword presence, context, and content quality to assess relevance. Creating highly relevant content increases the chance of ranking and satisfying the searcher.
Reputation Management
The process of monitoring, managing, and improving your brand’s perception online.
This may involve:
- Getting positive reviews
- Addressing negative feedback
- Publishing authoritative content
Strong reputation supports SEO, E-E-A-T, and conversions.
Resource Page

These pages are useful for link building if your content fits, reach out to be included.
Robots.txt
A file placed at the root of your domain that instructs search engines on which parts of your site they can or cannot crawl.
Useful for:
- Blocking admin pages
- Preventing duplicate content indexing
A misconfigured robots.txt can block important content, so handle with care.
ROI (Return on Investment)
A measure of the profitability of your marketing efforts.
Formula:
(Gain from investment – Cost of investment) ÷ Cost of investment
Use ROI to track the effectiveness of your SEO, ads, or content campaigns.
Schema Markup
A type of structured data added to your website’s code to help search engines better understand your content.
It enhances your listings with rich results like:
- Star ratings
- Event dates
- FAQs
Use Schema.org formats to improve visibility and CTR in search results.
Search Engine
A system (like Google, Bing, or DuckDuckGo) that helps users find information online by indexing and ranking webpages. Search engines use crawlers, algorithms, and ranking factors to serve the most relevant results.
SEO is the practice of optimising content to rank higher on search engines.
Search Engine Marketing (SEM)
A digital marketing strategy that includes both paid search advertising (PPC) and organic search (SEO).

Use categories, subcategories, breadcrumbs, and internal links for clarity.
Social Signals
Metrics such as likes, shares, and comments on social media platforms.
While not direct ranking factors, they can increase visibility, engagement, and link opportunities.
Spam Score
A Moz metric that predicts how likely a website might be penalised by Google based on certain red flags. High spam scores can indicate poor-quality backlinks or shady SEO practices.
SSL Certificate
A digital certificate that enables HTTPS encryption on your website, securing the connection between browser and server. Google considers HTTPS a ranking factor. It's essential for SEO and user trust.
Structured Data
A standardised format for providing information about a page and classifying the page content. It is used in schema markup to generate rich results in SERPs.
Subdomain vs. Subfolder
- Subdomain: blog.example.com
- Subfolder: example.com/blog
SEO professionals often recommend subfolders for content to consolidate authority under one root domain.
Sweat Equity Links
Links earned through manual outreach, content creation, and building relationships. They require time and effort but are often the most valuable and sustainable in the long run.
Tag
A tag is a descriptive keyword or label used to organise content.
- In SEO: Tags can refer to HTML elements (like title tags or meta tags).
- In blogs: Tags help group related posts.
While helpful for UX and internal organisation, excessive tagging can create thin or duplicate pages.

Aim for clean, efficient code and meaningful content to improve this balance.
Thin Content
Pages with little to no valuable or original information for users.
Examples:
- Auto-generated content
- Affiliate pages with no added value
- Duplicate or near-duplicate content
Google may penalise sites for having too much thin content. Quality is key.
Title Tag
An HTML element that defines the title of a webpage.
It appears:
- At the top of your browser tab
- In search engine results
It’s one of the strongest on-page SEO signals—use your primary keyword naturally and keep it under ~60 characters.
Top-Level Domain (TLD)
The final part of a domain name, such as .com, .co.uk, or .org. Some TLDs are country-specific (e.g., .pk for Pakistan), while others are generic.

Examples:
- “Buy SEO tools online”
- “Best digital marketing course deal”
These keywords often convert well and are ideal for landing pages.
Trust Flow
A Majestic SEO metric that scores a website based on the quality of its backlinks. Higher scores indicate more trustworthy and authoritative link profiles.
Trust Flow is useful in link audits to assess backlink value and spam risk.
Trust Signals
Elements on your site that build credibility with users and search engines.
Examples:
- SSL certificates (HTTPS)
- Reviews and testimonials

UGC (User-Generated Content)
Content created by your users rather than your brand.
Examples include:
- Blog comments

- Forum discussions
- Social media posts
UGC can enhance SEO by increasing content diversity, engagement, and long-tail keyword coverage but it must be moderated to avoid spam.
UI (User Interface)
The visual layout and interactive elements of a website that users interact with.
A well-designed UI:
- Makes content easier to find
- Improves usability
- Increases conversions
A clean UI complements good UX (user experience) and supports SEO indirectly by reducing bounce rates.
Unnatural Links
Backlinks that violate Google Search Essentials are typically manipulated to boost rankings.
Examples:
- Paid links

- Increase relevance and satisfaction
- Improve SERP performance
Align every page to a specific type of intent: informational, navigational, commercial, or transactional.
UTM Code (Urchin Tracking Module)
Tags you append to a URL to track campaign performance in Google Analytics.
Common parameters include:
- utm_source (e.g. Facebook)
- utm_medium (e.g. email, CPC)

Use UTM codes to understand which traffic sources are driving the best ROI.
Vertical Search
A specialised search that focuses on a specific category or industry.

Hosting on platforms like YouTube or embedding on your own site (with structured data) can drive both direct views and SERP visibility.
Visibility (Search Visibility)
A metric indicating how prominently a website appears in search engine results. Often tracked using tools like SEMrush, Ahrefs, or Moz, it reflects:
- The number of keywords a site ranks for
- The positions of those keywords
Higher visibility generally means more organic traffic—monitor this regularly for SEO performance tracking.
Voice Search
Search performed using voice-activated assistants such as Google Assistant, Siri, or Alexa.
Voice queries are typically:
- Longer
- Conversational
- Often question-based (e.g. “What is the best SEO plugin for WordPress?”)

Viral Content
Content that is rapidly and widely shared across the internet due to its appeal, entertainment, or usefulness.
SEO benefits:

Violating these guidelines can lead to ranking drops or manual actions.
Web Crawler
Also known as a spider or bot, this is a script used by search engines to scan and index content from websites.
Popular crawlers include:
- Googlebot (Google)
- Bingbot (Microsoft Bing)
Ensure your site is crawlable via a properly configured robots.txt and accessible internal linking.
Website Architecture
The organisational structure of a website's content and navigation.
A well-structured site:

Use a flat, logical structure and most content should be accessible within 3 clicks from the homepage.
Website Navigation
The menu or structure that helps users move around a website.
Includes elements like:

Ethical SEO practices that follow search engine guidelines.
This includes:
- High-quality content

- Domain registration and expiration date
- Registrar info
Tip: WHOIS is useful for link building research, transparency, or identifying spammy domains.
Widget Links
Links embedded in widgets (e.g. weather tools, calendars, counters) that appear across multiple websites. Google considers links in widgets unnatural if they are manipulative, keyword-rich, and not editorially placed.
Word Count
The total number of words on a page. While there’s no fixed ideal, sufficient word count helps ensure:
- Content depth
- Keyword relevance
- Semantic coverage
Note: Focus on quality, not just quantity. Long-form content often performs well when it's informative and well-structured.
WordPress
A popular content management system (CMS) used by millions of websites worldwide.
SEO benefits of WordPress include:

Pages or topics that could impact a person’s health, safety, finances, or overall well-being.
Examples include:
- Medical advice
- Financial guidance
- Legal information
Google applies stricter standards to YMYL pages, placing high importance on E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness).
Yahoo
A veteran web portal and search engine. While its influence has faded, Yahoo still serves search results powered by Bing and remains relevant for specific demographics and industries.
Yandex
The most widely used search engine in Russia. Yandex uses different ranking algorithms than Google, focusing more heavily on location and user behaviour within the Russian internet ecosystem.
Zero-Click Search
When a search query is answered directly on the search engine results page (SERP) without the need to click a result.
Examples:
- Featured snippets
- Knowledge panels
- Weather results
While this reduces organic traffic, optimising for featured snippets still builds visibility and brand authority.
Zombie Pages
Low-value pages that bring little or no traffic and can dilute a site’s SEO strength.
These may include:
- Thin content
- Outdated posts
- Duplicate pages
Perform content pruning or update these pages to boost overall site quality and improve rankings.
