The 7 on-page basics, explained simply
On-page SEO basics are the content-level elements within a page itself title tags, headings, content structure that help Google understand and properly evaluate what a page is about, distinct from the purely technical site infrastructure covered in our Technical SEO pillar.
Basic 1: A clear, specific title tag including your target keyword
The title tag, displayed as the clickable headline in Google's search results, should clearly and specifically describe what the page covers, naturally including your primary target keyword, ideally within the first part of the title where it carries somewhat more weight.
Basic 2: One clear H1 heading matching the page's actual primary topic
Every page should have exactly one H1 heading (the page's main, top-level heading), clearly stating the page's core topic, naturally incorporating the target keyword without forced, unnatural repetition.
Basic 3: A logical heading hierarchy (H2s and H3s) reflecting genuine content structure
Subheadings should genuinely reflect the page's logical content organisation each H2 representing a distinct sub-topic or section, with H3s nested appropriately beneath relevant H2s where further sub-division genuinely exists both helping readers navigate the content and helping Google understand its structure.
Basic 4: The target keyword appearing naturally within the first part of the content
Rather than mechanical keyword stuffing, the content's opening should naturally and clearly establish what the page is about, typically including the target keyword or a close natural variation within the first few sentences.
Basic 5: A meta description that genuinely describes the page and encourages clicking
While not a direct ranking factor in the same way as content itself, the meta description (the short summary text often shown beneath the title in search results) genuinely affects click-through rate a clear, specific, compelling description outperforms a generic or absent one.
Basic 6: Descriptive, specific image alt text
Every meaningful image should have alt text genuinely describing what it depicts, both supporting accessibility (covered in our Website Development pillar's accessibility basics every website should meet) and providing Google additional context about page content.
Basic 7: Genuine content length appropriate to comprehensively covering the topic
Not a fixed minimum word count applied mechanically, but content genuinely long enough to comprehensively address the topic and its natural sub-questions see why content depth beats content volume for why this should be driven by genuine comprehensiveness, not an arbitrary target number.
Why these basics matter even with excellent content underneath
Even genuinely excellent, comprehensive content can underperform if these structural on-page basics are absent or poorly executed they are the signals that help Google correctly understand and categorise what your genuinely good content is actually about, ensuring the quality you have invested in is properly recognised and evaluated.
Frequently asked questions
Most modern CMS platforms and SEO plugins (Yoast, RankMath for WordPress) handle several of these elements through guided forms during content creation, reducing the manual burden but genuine review and customisation (not just accepting auto-generated defaults) for each specific piece remains important.
Natural, readable phrasing that clearly includes the keyword or a close natural variation generally outperforms forced, exact-match phrasing that reads awkwardly Google's algorithm has become sophisticated enough to understand close variations and natural language, reducing the need for rigid, exact-match keyword insertion.
For content that is otherwise genuinely comprehensive and well-researched but has weak on-page structural elements, yes fixing these basics can meaningfully improve how well Google understands and evaluates already-strong underlying content, though it cannot compensate for genuinely thin or low-quality content underneath.
