On-page SEO: structuring pages and content to answer better than others
On-page: everything you control on the page itself
On-page SEO is the set of elements on your page that you control 100%: the title, the subheadings, the text, internal links, images, the URL. It's the most profitable link because it depends on no one else — no need to wait for another site to cite you or for Google to recrawl the whole web. A well-done on-page page clearly tells Google what it's about and shows the visitor that it answers their question. The two goals go together: you never optimize for the robot against the human.
The title tag and meta description: your storefront in the results
The title tag is the clickable title shown in Google. It's the most important relevance signal and your first hook: it should contain the main keyword, stay under ~60 characters, and make people want to click. The meta description (the short paragraph under the title) isn't a direct ranking factor, but it strongly influences click-through rate — so indirectly your SEO. On WordPress, Yoast or RankMath let you edit these two fields page by page, with a preview of how they look in Google. On Webflow, Shopify, Wix, these are native "SEO settings" fields. Never leave them empty or automatic: they're your free billboards.
The heading structure: a page you can read at a glance
A page is structured like a document: a single <h1> (the main title, the page's topic), then <h2>s for major sections, <h3>s for sub-points. This hierarchy helps Google understand the outline, and the human scan it. Good readability practices — short paragraphs, lists, tables, bold on the essentials — also serve SEO, because they lower the bounce rate: a visitor who quickly finds their answer stays, which Google reads as a quality signal.
Answering the intent: depth over length
You sometimes read that "you need 2,000 words to rank". That's a myth: Google doesn't count words, it assesses whether the page covers the topic better than competitors. The right length is the one that fully answers the intent, no more, no less. Concrete method: type your target query, open the first 5 results, list the questions and sub-topics they cover — and make sure you cover them at least as well, with your angle on top. Tools like Surfer SEO or Frase (subscriptions ~€50–90/month) automate this analysis: they compare your draft to the ranking pages and suggest missing themes. Useful past a certain content volume; superfluous when starting out.
Internal linking: the network that distributes authority
Internal links — from one page of your site to another — are a powerful and often-neglected lever. They help Google discover your pages, understand which ones matter, and distribute authority among them. Practical rule: every new article should point to 2–3 relevant pages on the site, and be pointed at from others. The link text (the anchor) should describe the destination ("our invoicing guide" rather than "click here"). Good internal linking turns a collection of isolated pages into a coherent site, where authority flows instead of stagnating.
Images: weight, name and alt text
Images weigh on two SEO fronts. First speed: an uncompressed image slows the page (more on this in the technical chapter) — compress with TinyPNG, Squoosh (free) or a plugin like ShortPixel. Second understanding: an explicit filename (freelancer-invoice.jpg rather than IMG_4821.jpg) and especially an alt text describing the image help Google index it and improve accessibility. The alt is also what gets you to appear in Google Images, a traffic channel in its own right.
The URL: short, readable, stable
A good URL is short, descriptive and readable: mysite.com/invoicing-guide beats mysite.com/p?id=4821&cat=3. It ideally contains the keyword, without unnecessary dates or parameters. Golden rule: never change a URL that ranks without setting up a 301 redirect (otherwise you lose the SEO you've earned). A structure thought through from the start beats a big overhaul later.
AI to produce faster, without losing value
An AI assistant hugely speeds up on-page work: generating an outline from competitor analysis, proposing ten title variants, drafting a first version, rephrasing a confusing passage, creating the meta description. But purely generated content, published en masse without expertise or verification, is exactly what Google has been trying to devalue since its "helpful content" updates. Best practice: AI for speed and structure, you for real experience, concrete examples, and fact-checking. A page that brings something no AI could invent alone — your lived experience, your numbers, your angle — is the one that lasts.
The on-page checklist for a page aiming for the top
Before publishing, check: a clear target intent, a catchy title with the keyword, a meta description that makes people want to click, a single <h1> and a logical <h2>/<h3> structure, content that covers the topic at least as well as the top 5, 2–3 relevant internal links, compressed images with alt, and a clean URL. This checklist, applied to every page, is worth more than any paid tool: it's discipline, not sophistication, that lifts pages.
