Search Engine Optimisation (SEO) is a multifaceted discipline designed to enhance the visibility and ranking of websites on search engines like Google. Given the complexity and evolving nature of search engine algorithms, SEO is typically categorised into three main types: on-page SEO, off-page SEO, and technical SEO. Each type plays a crucial role in a comprehensive SEO strategy, addressing different aspects of website optimisation to improve search engine performance. In this blog post, we will explore these three types of SEO services in detail, understanding their unique contributions and how they work together to drive organic traffic and improve search engine rankings.

1. On-page SEO

On-page SEO, also known as on-site SEO, involves optimising individual web pages to rank higher and earn more relevant traffic in search engines. This type of SEO focuses on the content and HTML source code of a page so that it can be optimised. The key elements of on-page SEO include:

Keyword Research and Optimisation

  • Keyword Research: The foundation of on-page SEO starts with identifying relevant keywords that potential customers are using to search for products or services. Tools like Google Keyword Planner, Ahrefs, and SEMrush are commonly used for this purpose.
  • Keyword Placement: Once the appropriate keywords are identified, they need to be strategically placed in various parts of the webpage, including:
  • Title Tags: The title tag should contain the primary keyword and be compelling enough to encourage clicks.
  • Meta Descriptions: Although not a direct ranking factor, a well-crafted meta description with relevant keywords can improve click-through rates.
  • Headings (H1, H2, H3, etc.): Using keywords in headings helps search engines understand the structure and relevance of the content.
  • Content: Naturally integrating keywords into the body of the text ensures the content is relevant and readable.

Content Quality and Relevance

Content is king in on-page SEO. Search engines prioritise high-quality, relevant content that provides value to users. Important aspects include:

  • Originality: Content should be unique and not duplicated from other sources.
  • Relevance: The content should be pertinent to the keywords and provide comprehensive information.
  • Engagement: Including multimedia elements like images, videos, and infographics can enhance user engagement and retention.

Internal Linking

Internal links help to distribute page authority and ranking power across the site. They also assist search engines in understanding the structure and hierarchy of a website. Effective internal linking involves:

  • Contextual Links: linking to relevant pages within the content to provide additional information.
  • Anchor Text: Using descriptive and keyword-rich anchor text for internal links.

URL Structure

Optimised URLs are short, descriptive, and include relevant keywords. They help search engines and users understand the content of the page. A well-structured URL might look like this:

Image Optimisation

Images should be optimised to improve page load speed and enhance the user experience. This involves:

  • Alt Text: Providing descriptive alt text that includes relevant keywords.
  • File Names: Naming image files with descriptive, keyword-rich names.
  • Compression: reducing the file size of images without compromising quality.

2. Off-page SEO

Off-page SEO refers to activities performed outside the boundaries of the website to improve its ranking. It primarily involves building backlinks from other websites to establish the site’s authority and trustworthiness. Key elements of off-page SEO include:

Link Building

Quality over quantity: Search engines prefer high-quality backlinks from reputable sites over a large number of low-quality links. Strategies for building high-quality backlinks include:

  • Guest Blogging: writing articles for other websites in exchange for a backlink.
  • Influencer Outreach: Collaborating with influencers who can link back to your site.
  • Content Marketing: Creating valuable content that naturally attracts backlinks.

Social media engagement

Active participation on social media platforms can indirectly influence SEO. Although social signals (likes, shares, and comments) are not direct ranking factors, they can amplify content visibility and drive traffic. Effective social media strategies include:

  • Sharing Content: Regularly sharing valuable content on social media.
  • Engagement: Interacting with followers and participating in relevant conversations.
  • Brand Awareness: Building a Strong Brand Presence on Social Media.

Online reputation management

A positive online reputation can enhance trust and credibility, which are critical for SEO. This involves:

  • Review Management: Encouraging satisfied customers to leave positive reviews on platforms like Google My Business, Yelp, and industry-specific sites.
  • Addressing Negative Feedback: Responding professionally and promptly to negative reviews and feedback.

Influencer Marketing

Partnering with influencers can help in gaining exposure and generating high-quality backlinks. Influencers can create and share content that includes links to your website, thereby boosting your site’s authority.

3. Technical SEO

Technical SEO focuses on optimising the infrastructure of a website to ensure that it meets the technical requirements of modern search engines. It involves several aspects that make a website faster, easier to crawl, and more understandable for search engines. Key elements of technical SEO include:

Website speed and performance

Page load speed is a critical ranking factor. Slow websites can lead to higher bounce rates and lower search rankings. Strategies to improve website speed include:

  • Optimising Images: compressing images and using the correct format.
  • Browser Caching: Enabling caching to reduce server response time.
  • Minifying Code: Reducing the size of CSS, JavaScript, and HTML files.


With the increasing use of mobile devices, having a mobile-friendly website is essential. This involves:

  • Responsive Design: Ensuring the website adjusts seamlessly to different screen sizes.
  • Mobile Usability: Making sure that buttons, links, and text are easily accessible on mobile devices.

Secure Sockets Layer (SSL)

Websites with SSL certificates (indicated by HTTPS in the URL) are preferred by search engines because they ensure a secure connection. SSL is a minor ranking factor but critical for user trust and data security.

Structured Data Markup (Schema)

Structured data helps search engines understand the content of a website and can enhance search results with rich snippets. Implementing schema markup involves:

  • JSON-LD: Using the JSON-LD format to add structured data to web pages.
  • Rich Snippets: Enhancing search results with additional information like ratings, reviews, and prices.

Crawlability and indexability

Ensuring that search engines can easily crawl and index the website is fundamental. This involves:

  • Robots.txt: Using the robots.txt file to control which pages search engines can crawl.
  • XML Sitemaps: Creating and submitting an XML sitemap to help search engines find and index all the pages on the website.
  • Canonical Tags: Using canonical tags to prevent duplicate content issues.

Fixing crawl errors

Regularly monitoring and fixing crawl errors ensures that search engines can access and index all important pages. This can be done through:

  • Google Search Console: Using tools like Google Search Console to identify and fix crawl errors.
  • Redirects: Implementing 301 redirects for any broken links or moved pages.


SEO is a dynamic and ongoing process that requires a comprehensive approach encompassing on-page SEO, off-page SEO, and technical SEO. Each type of SEO service addresses different aspects of website optimisation, and together they form a holistic strategy to improve search engine visibility and drive organic traffic. By understanding and implementing best practices in these three areas, businesses can enhance their online presence, attract more visitors, and ultimately achieve higher search engine rankings.
