15 min readFeb 7, 2024


Search Engine Optimisation (SEO) is the process of improving a website’s visibility in search engine results pages (SERPs) through organic or unpaid search. SEO helps ensure that a website appears prominently when users search for relevant keywords and phrases. With over 3.5 billion searches conducted on Google every day, SEO is crucial for driving qualified website traffic, leads, and sales.

Our guide will cover everything you need to know about SEO in 2024 — from core concepts to the latest trends shaping the industry.

What is Search Engine Optimisation (SEO) in 2024

What is SEO and Why is it Important?

SEO stands for Search Engine Optimisation. It refers to strategies, techniques, and activities undertaken to improve a website’s organic search performance and ranking in search engines like Google, Bing, and Yahoo. The goal is to place higher in search results for targeted keywords so the website can be easily discovered by searchers.

There are 3 main reasons why SEO is crucial for any business today:

  • Increased Visibility and Website Traffic — Websites ranking on the first page of Google for relevant search terms can expect more than 90% of overall search traffic for that keyword. SEO boosts visibility and the quantity of visitors to a website.
  • Higher Conversion Rates — Searchers who come through SEO, convert at 2 to 3 times higher rates than other sources. SEO delivers qualified website visitors more likely to become customers.
  • Competitive Advantage — With over 1.8 billion websites online, SEO differentiates a website from competitors. Ranking higher brings in more traffic and revenue opportunities.

As an investment, SEO provides an excellent return compared to other digital marketing channels. Studies show that on average, businesses generate $2 in revenue for every $1 spent on SEO activities. With the search market only growing more competitive, SEO is a must for any business looking to succeed online.

How Does SEO Differ from PPC and SEM?

SEO is one aspect of search marketing, which also encompasses paid advertising channels like pay-per-click (PPC) and search engine marketing (SEM). Here’s how they differ:

  • SEO focuses solely on earning unpaid, organic rankings in search engines through keyword research, site Optimisation, link building, and more. Results depend largely on the website’s efforts.
  • PPC (Pay-Per-Click) refers to paid ads displayed alongside organic results based on keywords. Advertisers bid on keywords and pay only when ads are clicked. Results depend on bidding strategy and budget. Here are most common PPC Errors you should avoid.
  • SEM (Search Engine Marketing) is the umbrella term for all search marketing activities — both organic SEO and paid PPC/PPC advertising. SEM looks at visibility holistically.

Many businesses leverage SEO and PPC together for a comprehensive search strategy driving traffic, leads, and sales. While SEO offers results that compound over time, PPC offers immediate results. They complement each other well as part of a complete SEM plan. Looking for Free PPC Tools check here.

There are several categories of SEO based on the focus and scope of Optimisation efforts:

On-Page SEO

  • Mobile Optimisation — Making pages mobile-friendly for local SEO and Google’s mobile-first indexing.

  • Social signals — Leveraging social media to generate shares, engagement, and brand mentions.
  • Reviews and mentions — Gaining positive reviews on platforms like Yelp and industry-specific sites. Mentions in press, media, etc.
  • Local SEO — Optimising online listings and citations for local search visibility.
  • Reputation management — Monitoring and maintaining a positive brand image online.

Technical SEO
Technical SEO establishes the technical foundations for search ranking success through:

  • Indexation — Ensuring all pages are fully crawled and indexed by search engine bots.
  • Page speed — Site speed Optimisation through techniques like minification, compression, caching, lazy loading, etc.
  • Mobile Optimisation — Making site design and development mobile-friendly.
  • Security — Implementing HTTPS and other security best practices.

Content Optimisation

Creating high-quality content that search engines identify as relevant. This involves:

  • Keyword research and topic research to identify demand and user intent.
  • Competitor analysis to benchmark content strategies of industry leaders.
  • Content gap analysis to find underserved topics and keywords.
  • Optimising content for keywords and answer-first intent based on research.
  • Creating link-worthy pillar content, guides, and resources that attract organic links.

  • Region-specific link building and outreach.

Why is Technical SEO the Foundation of Success?

Technical SEO establishes the underlying infrastructure and fundamentals for search Optimisation. Like the foundation of a house, it must be constructed properly first before further Optimisation can be impactful. Here are the core elements of technical SEO:

  • Crawlability — This ensures that search engine bots can easily discover and access all pages of a website for indexing. Proper internal linking, XML sitemaps, and eliminating crawl errors enable maximum indexing.
  • Indexation — Getting pages into the search index is the first step. Ensuring pages are properly crawled, rendered, and indexed without blocks or restrictions.
  • Mobile Optimisation — With mobile representing over 50% of search traffic, having a mobile-friendly and responsive website is a prerequisite today. From design to page speeds, a site must function seamlessly on mobile devices.
  • Site Architecture — A search-friendly information architecture, site structure, internal linking, URL structure and more allow search bots to easily navigate and consume content.
  • Page Speed — With page speed being a ranking factor, performance Optimisation through minification, compression, caching, lazy loading, and more improves user experience. Google recommends a page load time under 2–3 seconds.
  • Security — Implementing HTTPS, eliminating mixed content errors, removing malware, and addressing other security issues builds trust and credibility with search engines.
  • Fixing Technical Errors — Identifying and correcting HTML errors, broken links, duplicate content issues, structured data errors, and other technical problems prevents ranking penalties.

Without strong technical SEO, other efforts like content creation and link building will be less impactful. The optimal technical foundations empower the success of further Optimisation efforts.

Growing Impact of User Experience in SEO

Historically, SEO focused heavily on optimising for search engines based on understanding their algorithms and technical inner workings. However, the search landscape has shifted dramatically with user experience emerging as a key ranking factor.

Google’s algorithms and search quality team now places greater emphasis on understanding and satisfying user intent through relevant, helpful content. Metrics like bounce rate, dwell time, and pages per session indicate how satisfying a user found the content. Greater engagement signals higher quality content.

Elements of on-page SEO like readability, mobile Optimisation, page speed, and even aspects of technical SEO ultimately aim to improve user experience. The content itself must evolve to not just target keywords, but answer user questions and provide tangible value.

Consequently, SEO professionals now also serve as user experience evaluators. Site audits incorporate user perspective, looking at site navigation, page layouts, content formatting, and more from the eyes of users. User testing helps reveal pain points and areas of opportunity. The rise of AI may provide more scalable ways to incorporate user perception signals in the future.

This growing emphasis on human metrics beyond just algorithms highlights the need for content to be genuinely helpful, clear, and engaging to rank well. While technical Optimisation remains important, the user experience is now central to success.

How to Conduct SEO Keyword Research

Thorough keyword research provides the foundation for an effective SEO strategy. It reveals what users are searching for, helping create content that matches intent. Follow these steps:

  • Brainstorm seed keywords — List down primary keywords and topics related to your business as a starting point.
  • Leverage keyword tools — Tools like Google Keyword Planner, SEMrush, and Ahrefs provide search volume data, suggested keywords, and competitor analysis.
  • Analyse top-ranking content — Study what content performs best for target keywords to identify Optimisation opportunities.
  • Identify long-tail keywords — Longer, more specific long-tail keywords often have less competition and more conversions.
  • Group keywords by theme — Organise keywords into topics and clusters to guide content development.
  • Prioritise keywords — Focus on higher volume keywords appropriate for each page first before targeting less competitive long-tail terms.
  • Refine ongoing — Continuously analyse search trends and optimise priority keywords based on searcher behaviour.

Keyword research provides the blueprint for SEO content creation and Optimisation efforts. Dedicating time to truly understand user intent ensures content better answers search queries.

How to Create SEO-Friendly Content

Optimised content brings in qualified organic traffic by targeting relevant topics and keywords. Here are tips for creating SEO-friendly content:

  • Conduct competitor analysis — Study content from reputable sites ranking well for target keywords to identify what works. Derive best practices based on their successes.
  • Focus on quality over quantity — Well-researched, comprehensive content with unique insights is more valuable than superficial content with target keywords forcefully inserted.
  • Answer the reader’s query — Content should directly respond to the question or intent behind a keyword, helping the reader.
  • Include target keywords naturally — Use keywords in titles, headers, opening paragraphs, URLs, file names, meta descriptions, and image alt text. But avoid over-Optimisation.
  • Format content for skimmability — Break down content into easy-to-scan sections with visually distinct headers, lists, bullets, bolding, and more.
  • Optimise media elements too — Insert keywords in video titles, captions, and transcripts. Leverage image SEO through file names and alt text.
  • Write concise summaries — Well-written meta descriptions that summarise content help click-through-rates.
  • Link to internal resources — Reference related content with contextual internal links to highlight your expertise.
  • Update and refresh content — Add new information over time rather than leaving stale, outdated content.

Creating SEO content goes beyond keyword targeting. The content must offer true value to earn links and engagement. Focus on satisfying user intent with helpful, engaging content.

Why is an SEO-Friendly Site Structure Important?

A website’s information architecture — how content is organised and structured — significantly impacts SEO success. A site structure optimised for search engines and users boosts discoverability. Elements of a search-friendly site architecture include:

  • Logical hierarchy — Organise content in a logical hierarchy starting with broad topic categories and progressing into more granular sub-topics.
  • Targeted pages — Create topic-specific landing pages that focus on a single keyword theme to rank for specific queries.
  • Short URLs — Use brief but descriptive page URLs with hyphens instead of underscores and dynamic parameters.
  • Keyword-focused headers — Headers and subheadings help indicate the topic of a page section to search engines.
  • Intuitive navigation — The site menu and internal linking structure should enable intuitive user navigation between related content.
  • Quality over quantity — Focus on developing fewer in-depth pages rather than thin, duplicate content spread over many pages.
  • Mobile-friendliness — Use responsive design and check how site navigation works on mobile. Hidden menus, vague labels, and tiny links frustrate mobile users.
  • Cohesive linking — Links between pages should include anchor text with relevant keywords to highlight the relationship. But avoid overuse of keywords in anchor text.
  • Breadcrumb navigation — Breadcrumbs help indicate page hierarchy and provide intuitive in-site navigation for users.

Optimising site architecture goes beyond technical SEO to also improve usability. A thoughtful site structure enhances user experience and satisfaction.

Role of Link Building in SEO

In SEO, links represent votes of confidence. High-quality links from relevant external sites help build domain authority and rankings. But not all links are equal in value and impact. Here are best practices for link building:

  • Earn links organically — Focus on creating assets like blogs, tools, and resources that websites naturally want to link to rather than low-quality manipulated links.
  • Prioritise relevant sites — Get links from websites closely related to your industry or content for greater impact.
  • Focus on trustworthy sites — Links from highly credible and trusted websites pass on more equity compared to new or questionable sites.
  • Diversify link types — Aim for a blend of editorial links, directories, profiles, mentions, etc. Don’t rely only on one link type.
  • Monitor link velocity — Build links slowly and steadily rather than a sudden spike which can appear unnatural.
  • Assess competitors’ links — Research where top competitors earn links from to identify new partnership opportunities.
  • Disavow toxic links — If hit with an unnatural link penalty, identify and immediately disavow low-quality paid or manipulative links pointing to your site.
  • Link internally too — Interlink relevant pages together using keywords to highlight your expertise around a topic.

Achieving a diverse, high-quality link profile demonstrates subject matter expertise to search engines. But focus on building relationships rather than chasing links.

Tracking and Measuring SEO Performance

Key metrics help evaluate how SEO efforts impact behaviour and business results. SEO KPIs include:

  • Organic traffic — Total visits from organic search, and monthly trends. Indicates search visibility.
  • Organic conversions — Conversions from organic search such as form fills, purchases, etc. The goal of SEO.
  • Click-through-rate (CTR) — Clicks on a search listing divided by impressions. Indicates listing quality.
  • Rank tracking — Monitoring keyword rankings in search engines to identify gains/losses.
  • Mobile vs. desktop — Comparing metrics on mobile and desktop to optimise accordingly.
  • Site authority — Scores from tools like Moz’s Domain Authority and Ahrefs’ Domain Rating based on linking factors.
  • Indexation — The percentage of site pages Google has in its index out of total pages.
  • Page speed metrics — Page load times, Lighthouse scores, and mobile-friendliness tests.
  • Traffic by landing page — Identifying which pages attract the most organic search visits.
  • ROI — Calculating SEO return on investment based on the value derived from site traffic and conversions.

Regularly tracking key metrics identifies issues and opportunities to continuously refine and improve SEO efforts. Dashboards and reporting bring greater accountability.

Importance of Developing an SEO Strategy

A documented SEO strategy aligned to wider business goals provides focus and direction for activities. A streamlined SEO strategy should cover:

  • Business objectives — What goals does SEO help achieve? More leads, sales, brand awareness? Identify core KPIs.
  • Target audience — Who are you trying to attract? Detail demographics, buyer persona, preferences, pain points, and journey.
  • Keyword opportunities — Output of keyword and competitor research revealing top terms to target.
  • Current performance — Analysis of existing site traffic, keywords ranking for, gaps, strengths/weaknesses.
  • Link building — Tactics for earning high-quality links from industry websites.
  • Content plan — Format, length, topics, promotion plans for new SEO content.
  • Technical Optimisations — Site speed, mobile, crawl errors, indexing to address.

  • Budget allocation — Estimated costs for tools, content development, outreach, etc.

Documenting strategy enables alignment across teams and stakeholders while providing a reference point for planning and evaluating SEO.

Common SEO Mistakes to Avoid

While best practices evolve constantly in SEO, some missteps continue sabotaging efforts. Here are common SEO mistakes to avoid:

  • Using duplicated or thin content just to target keywords, rather than creating truly unique, useful content.
  • Obsessive keyword density Optimisation that makes content unnatural. Focus on intent matching.
  • Over-optimising with keywords to manipulate search engines rather than optimising for actual users.
  • Buying links or private blog networks instead of earning high-quality editorial links organically.
  • Moving too fast by rapidly scaling low-quality links, which gets penalized. Build links slowly.
  • Having an unfocused, broad targeting of too many disparate keywords rather than identifying priority targets.
  • Not having a responsive mobile-friendly site in today’s mobile-first world.
  • Ignoring site speed. Slow load times frustrate users and affect rankings.
  • Using messy structured data markup that conflicts, duplicates, or has errors.
  • Failing to regularly create fresh content. Search engines favor websites actively publishing new, useful content.
  • Not tracking the right metrics to evaluate performance, identify issues, and demonstrate SEO ROI.
  • Lacking site security measures like HTTPS, SSL certificates, and elimination of malware.

Avoiding common mistakes and pitfalls through informed best practices helps steer SEO success.

Importance of Ongoing Learning in SEO

SEO is in constant flux, demanding ongoing education and learning to stay updated. Here are insights on continual SEO learning:

  • Follow SEO blogs and resources — Trusted sites like Search Engine Journal, Moz, and Semrush publish regular educational content to build knowledge.
  • Attend conferences and events — Industry conferences like Pubcon, SearchLove, and SMX are opportunities to learn cutting-edge tactics.
  • Leverage online courses and training — Affordable programs on Udemy, Coursera, LinkedIn Learning, etc. make self-education accessible.

  • Connect via forums and groups — Digital marketing communities like r/SEO provide discussions and peer learning.
