On-Page SEO

Optimise every page to rank for what it should

On-page SEO is the process of optimising the content and HTML elements of individual pages so that search engines can accurately understand what each page is about, who it is for and how relevant it is to a given search query.

Technical SEO ensures Google can crawl and index your site. Link building builds your authority. On-page SEO is the layer that ties it all together: making sure that when Google does crawl your pages, every signal on them points clearly towards the keyword targets you are trying to rank for.

Done correctly, on-page SEO can significantly improve the rankings of pages that already have authority, and it is often the fastest path to measurable gains without waiting for new links or content to mature.

Title tags and meta descriptions The most visible on-page elements in search results. Correctly written title tags improve both rankings and click-through rates from the results page.
Heading structure and content H1, H2 and H3 headings that signal page structure and keyword relevance clearly to Google, with content that matches the depth and intent of top-ranking pages.
Internal linking strategy Correctly structured internal links distribute authority across your site, guide users through relevant content and signal to Google which pages are most important.
Image optimisation and alt text Descriptive alt attributes, compressed file sizes and correct file naming contribute to both accessibility and rankings, including visibility in Google image search.
What's included

What our on-page SEO service covers

A thorough page-by-page review and optimisation of every element that influences how search engines understand and rank your content.

Title tag optimisation Every page title rewritten to contain the primary keyword, stay within the optimal character count and include a compelling reason to click, without keyword stuffing or truncation in search results.
Meta description optimisation Meta descriptions written to accurately summarise page content, include target keywords and contain a clear call to action that improves click-through rate from search results.
Heading structure (H1 to H3) A single, keyword-rich H1 on every page with a logical heading hierarchy that helps both users and search engines understand how the page content is structured and what each section covers.
Content gap analysis and expansion Comparing your page content against the top-ranking pages for your target keywords to identify what topics, questions and depth of information yours is missing.
Keyword placement and density Ensuring primary and secondary keywords appear naturally in the right locations: the H1, early in the body content, in subheadings where appropriate and in image alt text, without over-optimisation.
Internal linking audit and improvement Building a structured internal link architecture that distributes authority effectively, creates clear topical clusters and guides both users and search engines through your most important content.
Image alt text and file optimisation Descriptive alt attributes on all images, correct file naming conventions and compression to support both accessibility compliance and rankings in Google image search.
Schema markup implementation Structured data that helps search engines understand the type of content on each page, unlocking rich result enhancements and supporting AI search visibility as part of the same on-page work.

Common issues

On-page mistakes that suppress your rankings

Most sites have at least a handful of these issues across their important pages. Each one is a signal to Google that the page is not as well optimised as it could be, and each one is fixable.

Title tags that do not include the target keyword

Generic page titles like "Home" or "Services" tell Google nothing about what the page is for. A well-optimised title is one of the fastest single improvements you can make to a page's ranking potential.

Multiple H1 tags or no H1 at all

A page with no H1 gives Google no primary signal about its topic. Multiple H1 tags dilute the signal and confuse the heading hierarchy that search engines use to understand page structure.

Thin content that underserves search intent

If the top-ranking pages for your target keyword average 1,200 words and your page has 300, Google has every reason to rank them above you. Content depth is a direct on-page ranking factor.

No internal links from or to the page

Isolated pages receive no authority from the rest of the site and are harder for Google to discover. Internal linking is how you distribute your domain's authority to the pages that matter most.

Missing or generic image alt text

Images without alt text are invisible to search engines. Alt text provides additional keyword context for the page and enables the image to rank in Google image search, adding a supplementary traffic source.

Duplicate title tags across multiple pages

When multiple pages share the same title tag, Google cannot distinguish between them and may suppress both. Every page on your site should have a unique title that reflects its specific content and keyword target.

The three pillars

Where on-page SEO fits in the bigger picture

On-page SEO is one of three core pillars of organic search performance. Understanding how it relates to the others helps you prioritise where to invest first and why each pillar matters.

Pillar 1

Technical SEO

The foundation. Without this, even perfectly optimised pages may not be crawled, indexed or rendered correctly by Google.

  • Crawlability and indexing
  • Page speed and Core Web Vitals
  • Site structure and sitemaps
  • Redirect management
Pillar 2: this service

On-Page SEO

Signals within each page that tell Google what it is about, what intent it serves and how relevant it is to specific searches.

  • Title tags and meta descriptions
  • Heading structure and content
  • Keyword placement and depth
  • Internal links and schema markup
Pillar 3

Off-Page SEO

Authority signals from outside your site. Backlinks, brand mentions and entity recognition that tell Google your content is worth ranking highly.

  • Backlink acquisition
  • Digital PR and brand mentions
  • Entity building and citations
  • Review signals and social proof

On-page SEO delivers the fastest wins when authority already exists. If your domain has backlinks and authority but your pages are poorly optimised, on-page work can produce significant ranking improvements quickly. We assess all three pillars before recommending where to focus first.

FAQs

On-page SEO questions, answered

What is on-page SEO?
On-page SEO is the practice of optimising the elements within individual web pages to improve their relevance and ranking potential for specific search queries. This includes title tags, meta descriptions, heading structure, content, internal links, image alt text and schema markup. It is distinct from technical SEO, which covers crawlability and site infrastructure, and off-page SEO, which covers backlinks and authority.
How quickly does on-page SEO show results?
On-page SEO can produce visible ranking improvements within a few weeks, particularly for pages that already have some authority and where the optimisation gap compared to competing pages is significant. It is often the fastest-acting SEO lever available, especially when technical issues are already resolved and the site has existing backlinks.
Is on-page SEO a one-time job?
The initial optimisation is a one-time process per page, but it benefits from ongoing review. Search intent evolves, competitor content improves and Google updates its algorithms. Pages that ranked well after initial optimisation may need revisiting 6 to 12 months later to maintain their position. We recommend scheduling a review of your most important pages at least annually.
How is on-page SEO different from content marketing?
Content marketing focuses on creating new content to attract audiences and build authority. On-page SEO focuses on optimising existing pages so they rank better for their target keywords. The two overlap significantly, as on-page SEO work often involves improving and expanding existing content, but on-page SEO has a more specific technical focus on the signals that influence rankings.
Can on-page SEO improve rankings without new backlinks?
Yes. Pages that are underoptimised relative to their authority can often improve rankings significantly through on-page work alone. If a page has existing backlinks pointing to it but is missing obvious on-page signals, fixing those signals can produce meaningful ranking improvements without waiting for new links. That said, for competitive terms, both on-page quality and off-page authority are typically required to reach the top positions.
Do you work on existing pages or only new ones?
Primarily existing pages. On-page SEO delivers the most value when applied to pages that already exist on your site but are underperforming for their target keywords. We audit your current page inventory, identify the highest-priority opportunities and implement improvements to the pages most likely to move with optimisation.
