SEO Fundamentals

The core vocabulary every business owner should know before hiring an SEO company or reading an audit report.

SEO

Search Engine Optimization β€” the practice of improving a website so it ranks higher in unpaid (organic) search results on Google, Bing, and increasingly AI-powered answer engines. Learn more →

Search Engine Optimization

The full name for SEO: the ongoing process of making a website more relevant, trustworthy, and technically accessible so search engines rank it higher for relevant queries.

SERP

Search Engine Results Page β€” the page a search engine shows after a query, made up of organic listings, ads, and features like the Local Pack, Featured Snippets, and AI Overviews.

Organic Traffic

Visitors who arrive at a website by clicking an unpaid search result, rather than an ad, email, or social link. It’s the primary metric SEO work aims to grow.

Search Query

The exact words or phrase a person types or speaks into a search engine, such as β€œSEO company in Vadodara.”

Keyword

A word or phrase that content is optimised to rank for, chosen because real customers use it when searching for a product or service.

Search Intent

The underlying goal behind a search query β€” informational, navigational, commercial, or transactional. Matching content to intent is more important than matching exact keywords.

Ranking

A page’s position in the search results for a given query. Position 1 gets dramatically more clicks than position 10.

Visibility

A measure of how often and how prominently a website appears across relevant search results, combining rankings across many keywords into one health signal.

Search Engine

A system such as Google or Bing that crawls, indexes, and ranks web pages to answer user queries.

Bing

Microsoft’s search engine. Smaller market share than Google but still a meaningful traffic source, and its index also powers some AI assistants.

Index

Google’s massive database of web pages it has crawled and stored. A page must be indexed before it can rank for anything.

Crawling

The process by which search engine bots (like Googlebot) discover pages by following links and reading sitemaps.

Indexing

The process of a search engine analysing a crawled page and storing it in its index so it’s eligible to appear in results.

Ranking System

One of the many algorithms Google runs to score and order pages for a given query β€” Google uses hundreds of these together, not one single formula.

Algorithm

The set of rules and signals a search engine uses to decide which pages best answer a query and in what order to show them.

Search Results

The full list of organic listings, ads, and features returned for a query β€” see SERP.

Technical SEO

The infrastructure work that determines whether Google can crawl, index, and rank a site at all β€” the foundation everything else depends on.

Technical SEO

The practice of optimising a website’s infrastructure β€” speed, crawlability, indexing, structured data, and mobile usability β€” so search engines can access and understand it properly. Learn more →

Crawlability

How easily a search engine’s bots can access and navigate a site’s pages, largely determined by internal linking, robots.txt rules, and site structure.

Crawl Budget

The number of pages a search engine bot will crawl on a site within a given time period. Large sites need to manage this carefully so bots don’t waste time on low-value pages.

Googlebot

Google’s web-crawling bot that discovers and downloads pages to feed into Google’s index.

Indexability

Whether a specific page is technically eligible to be added to a search engine’s index, based on its meta tags, canonical settings, and crawl accessibility.

Index Bloat

A situation where a site has far more low-value or duplicate pages indexed than it should, diluting crawl budget and confusing relevance signals.

Robots.txt

A text file at a site’s root that tells search engine bots which sections of the site they are and aren’t allowed to crawl.

XML Sitemap

A structured file listing a site’s important URLs, submitted to search engines to help them discover and prioritise pages for crawling.

HTML Sitemap

A user-facing page listing a site’s key pages as clickable links, primarily for site visitors rather than search engine bots.

Canonical URL

The single, preferred version of a page’s URL that a site tells search engines to index when duplicate or near-duplicate versions exist.

Canonicalization

The process of choosing and signalling the canonical URL for a page, typically via the rel=β€œcanonical” tag, to prevent duplicate content issues.

Noindex

A meta tag or header instruction telling search engines not to include a specific page in their index, even if it’s crawlable.

Nofollow

An attribute added to a link that tells search engines not to pass ranking credit through it, commonly used for paid, sponsored, or untrusted links.

X-Robots-Tag

An HTTP header version of meta robots directives (like noindex or nofollow), used for non-HTML files such as PDFs and images.

HTTP Status Code

A three-digit code a server returns for every page request, signalling whether it succeeded (200), redirected (301/302), or failed (404/500).

200 Status Code

The standard HTTP response confirming a page loaded successfully.

301 Redirect

A permanent redirect that sends both users and search engines from an old URL to a new one, passing along most of the original page’s ranking value.

302 Redirect

A temporary redirect signalling the move is short-term, so search engines generally keep the original URL indexed rather than replacing it.

404 Error

The status returned when a requested page doesn’t exist. Too many uncontrolled 404s can waste crawl budget and hurt user experience.

410 Status Code

A status telling search engines a page is permanently gone, prompting faster removal from the index than a standard 404.

500 Error

A server error indicating something went wrong on the site’s end rather than the page simply not existing β€” frequent 500 errors can hurt crawling and rankings.

Redirect Chain

A sequence of multiple redirects between the original URL and the final destination, which slows page load and can dilute ranking signals.

Redirect Loop

A configuration error where redirects point back to each other endlessly, making the page inaccessible to both users and search engines.

Orphan Page

A page with no internal links pointing to it, making it hard for search engines and users to discover through normal site navigation.

JavaScript SEO

The practice of ensuring content built or loaded with JavaScript is still crawlable, renderable, and indexable by search engines.

Rendering

The process of a browser or search engine executing a page’s HTML, CSS, and JavaScript to produce the final visible content.

Server-Side Rendering

A setup where a page’s full HTML is generated on the server before being sent to the browser, making content immediately visible to crawlers.

Client-Side Rendering

A setup where a page’s content is built in the browser via JavaScript after the initial HTML loads, which can delay or complicate how search engines see the content.

Core Web Vitals

Google’s set of page-experience metrics β€” LCP, INP, and CLS β€” that measure loading speed, interactivity, and visual stability as a ranking signal.

LCP

Largest Contentful Paint β€” a Core Web Vital measuring how long it takes for the largest visible element on a page to fully load.

INP

Interaction to Next Paint β€” a Core Web Vital measuring how responsive a page feels when a user clicks, taps, or types.

CLS

Cumulative Layout Shift β€” a Core Web Vital measuring how much a page’s layout unexpectedly shifts while it’s loading.

TTFB

Time to First Byte β€” the time between a browser requesting a page and receiving the first byte of the server’s response, an early signal of server speed.

Page Speed

How quickly a page loads and becomes usable, a factor in both rankings and conversion rate.

Mobile-First Indexing

Google’s practice of using the mobile version of a site’s content for indexing and ranking, since most searches now happen on mobile devices.

HTTPS

The secure, encrypted version of the HTTP protocol. Google treats HTTPS as a baseline trust and ranking signal.

Website Architecture

How a site’s pages, categories, and internal links are organised β€” a clear architecture helps both users and search engines find and understand content.

URL Structure

How a site’s URLs are formatted and organised, ideally short, descriptive, and reflecting the site’s logical hierarchy.

Internal Linking

Links connecting pages within the same website, used to distribute ranking authority and help both users and search engines navigate related content. Learn more →

Log File Analysis

Reviewing a server’s raw access logs to see exactly how search engine bots are crawling a site, revealing crawl budget waste and access issues that other tools miss.

Also relevant here (defined above)

On-Page SEO

The optimisation work done directly on a page β€” content, structure, and HTML elements β€” that tells search engines what it’s about.

On-Page SEO

Optimising individual page elements β€” titles, headings, content, and internal links β€” so a page is both relevant to a target query and clearly structured for search engines. Learn more →

Title Tag

The HTML element defining a page’s title, shown as the clickable headline in search results and browser tabs β€” one of the strongest on-page ranking signals.

Meta Description

The short HTML summary of a page’s content, often shown beneath the title in search results. It doesn’t directly affect rankings but strongly influences click-through rate.

H1

The main heading tag on a page, typically matching the page’s core topic and used once per page.

H2

A secondary heading tag used to break a page into major sections, helping both readers and search engines understand its structure.

H3

A sub-heading tag nested under an H2, used to organise more granular subsections of content.

Heading Structure

The logical hierarchy of H1, H2, and H3 tags on a page, which should mirror an outline rather than being used for visual styling alone.

Alt Text

A written description attached to an image, used by screen readers for accessibility and by search engines to understand image content for image search.

Image SEO

Optimising images β€” file names, alt text, compression, and format β€” so they load fast and are eligible to rank in image search.

Keyword Placement

Positioning target keywords naturally in a page’s title, headings, and early content so both users and search engines quickly grasp its relevance.

Anchor Text

The clickable, visible text of a hyperlink, which gives search engines context about what the linked page is about. Learn more →

Content Optimization

Refining a page’s existing content β€” structure, depth, keyword coverage, and clarity β€” to better match search intent and improve rankings.

Keyword Density

The frequency of a keyword relative to a page’s total word count. Modern SEO treats this as a minor signal compared to overall topical coverage.

Keyword Cannibalization

A problem where multiple pages on the same site target the same keyword, splitting ranking signals and confusing search engines about which page to rank.

Duplicate Content

Substantially identical content appearing on multiple URLs, either within a site or across the web, which can dilute rankings and waste crawl budget.

Thin Content

Pages with little unique value or substance, which Google is less likely to rank and may flag as low quality.

Content Pruning

Removing, merging, or improving low-performing pages to concentrate a site’s authority on its strongest content.

Content Refresh

Updating an existing page’s information, examples, or structure to keep it accurate and competitive without starting from scratch.

Rich Result

Also relevant here (defined above)

Semantic SEO

How search engines understand meaning, context, and relationships between concepts β€” beyond just matching exact keywords.

Impressions

The number of times a page appeared in search results, regardless of whether it was clicked, as reported in Google Search Console.

Clicks

The number of times users clicked through from search results to a page, the most direct traffic metric in Search Console.

CTR

Click-Through Rate β€” the percentage of impressions that resulted in a click, a key signal of how compelling a title and description are.

Average Position

The average ranking position a page held across all the queries it appeared for, as reported in Search Console.

Conversion Rate

The percentage of visitors who complete a desired action β€” a purchase, form fill, or call β€” after arriving via organic search.

Bounce Rate

The percentage of visitors who leave a site after viewing only one page, though modern analytics increasingly favour engagement-based metrics instead.

Engagement Rate

A metric measuring how actively users interact with a site β€” time on page, scroll depth, or multiple page views β€” used alongside or instead of bounce rate.

Indexed Pages

The number of a site’s pages that Google has actually added to its index and can potentially rank.

Crawl Errors

Issues Googlebot encounters while attempting to crawl a site’s pages, such as timeouts, blocked resources, or server errors.

Ahrefs

A paid SEO platform best known for its backlink database, alongside keyword research, content analysis, and rank tracking features.

PageSpeed Insights
