On-page SEO.
On-page SEO is what happens on the page: content, headings, meta, internal linking. Everything Google and AI see when they actually read the content. Together with technical SEO and off-page SEO it makes a three-part foundation.

On-page is where the reader and the machine meet. Win both and you win the search result.
What on-page SEO is.
On-page SEO is all the work done on the page itself to make Google and AI understand what it's about and why it's valuable. Distinct from technical SEO (how the page is built) and off-page SEO (links from other sites), but connected to both: technical enables, on-page communicates, off-page validates. Google's SEO starter guide↗ summarises the foundations.
The decisive thing for on-page is the match between search intent and answer. A searcher googling 'what is technical SEO' wants an explanation, not a sales pitch. A searcher googling 'SEO agency Gothenburg' wants a service page, not a blog post. The same keyword can have different answers depending on intent. On-page work is hitting the right answer.
For AI search, the demand for clear structure has risen. An AI extracting an answer looks for extractable chunks: a definition in the first paragraph, a bullet list after, an FAQ at the end. Prose that meanders between topics extracts worse than prose that answers the question directly.
What on-page SEO includes.
Four components carry the work. They depend on each other: without content no heading structure matters, without headings content disappears for the reader.
Content
The text on the page. Does it match search intent? Does it answer the primary keyword within the first screen? Does it cover related questions (PAA, semantic synonyms)? Length matters less than coverage and relevance.
H structure
One H1 per page that defines what it's about. H2 for main sections, H3 below where needed. Logical hierarchy helps both readers and AI scan the page.
Meta title and description
The meta title shows in search results and is a strong signal for Google. Roughly 60 characters max. The meta description doesn't rank directly but affects CTR, roughly 155 characters max. Both should reflect the page's focus.
Internal linking
Links between related pages. Builds cluster authority (spoke pages point up to the hub, the hub points down to spokes). Also helps crawlers understand hierarchy and topical proximity.
Common misconceptions.
On-page SEO is probably the SEO area with the most myths around it. Three worth clearing:
- 'Keyword density should be two percent.' No. Google doesn't measure keyword density as a separate factor. What counts is that the keyword and its synonyms appear naturally in the text's context. Google's helpful content guidelines↗ prioritise relevance over density. Stuffing a keyword a dozen times tends to lower the quality of the text instead.
- 'Meta description affects ranking.' Not directly. The meta description isn't a ranking factor in itself, but it affects CTR (click-through rate) from the search results. And click data isn't meaningless: testimony from the DOJ antitrust trial against Google (2023) indicates that a system called Navboost weighs click signals. A good meta can therefore lift an already strong position higher.
- 'H1 must contain the exact keyword.' Not necessarily. H1 should be descriptive and readable, and handle the keyword naturally. 'What is SEO?' is a better H1 than 'SEO search engine optimization Sweden 2026' even though the latter is 'denser' on keywords.
How we work with on-page SEO.
On-page is part of every SEO engagement we do. We rarely sell it as a standalone deliverable because the effect comes from combining it with technical and off-page. That said, on-page work can be a clearly scoped sprint within an engagement, typically a review of prioritised pages with concrete change proposals per page.
The optimization work is always paired with the reader in mind. A page that ranks but reads poorly doesn't convert. We measure both: SERP position via Search Console↗, engagement via Plausible or your analytics.
If you have your own copy team we work as strategic advisers and template producers. If you don't, we bring in a writer from the network. Everything is documented, no secret methodology.

What is on-page SEO?
All SEO work that happens on the page itself: content, headings, meta tags, internal linking. Different from technical SEO (how the page is built) and off-page SEO (external links). Together they form a three-part foundation.
What's the difference between on-page and off-page SEO?
On-page is what you control on your own page: text, structure, meta. Off-page is signals from outside, primarily links from other websites. Both are needed. Beautiful on-page without off-page rarely ranks. Strong off-page without on-page rarely converts.
What are the four types of SEO?
Common split: on-page (content and structure), technical SEO (code and performance), off-page (links) and local SEO (for geographic searches). Some count AEO (AI search optimization) as a fifth, we see it as an evolution of the others.
How do you optimize a page for SEO?
Start with search intent. Answer the primary keyword directly within the first screen. Use clear H structure. Set a descriptive meta title and description. Link internally to related content. Then read it as if you were a visitor who knows nothing about your industry.
Is there an on-page SEO checklist?
Yes, many sites publish them. The value of a generic checklist is limited because priorities differ by page type (category, product, article, service). We do per-page reviews instead: shorter, more relevant, easier to act on.
