On-page SEO is everything you control on the page itself to help it rank: the title, the headings, the body copy, the internal links and the structured data. Unlike off-page work, you don’t need anyone’s permission — you can ship most of these improvements today. This checklist is the exact running order we use when optimising a page for a target keyword.
Start with search intent, not the keyword
Before touching the copy, look at what already ranks for your keyword. Are the top results guides, product pages, comparisons or local listings? That tells you the intent Google is rewarding. A page targeting “best CRM for small business” needs a comparison format; one targeting “buy office chairs Singapore” needs a product or category page. Match the format or you’ll struggle no matter how good your writing is.
Title tags and meta descriptions
The title tag is still one of the strongest on-page signals. Keep it under roughly 60 characters so it doesn’t truncate, put the primary keyword near the front, and make it click-worthy — a year, a benefit or a number helps.
- Title: one clear primary keyword per page, no stuffing.
- Meta description: 140–160 characters, include the keyword, write it as ad copy to lift click-through. It’s not a ranking factor but it drives clicks.
- One H1 per page that reflects the topic — in most CMSes the post title is the H1, so don’t add a second.
Headings and content structure
Use H2s and H3s to break the page into logical sections that mirror the questions a searcher has. Work your primary keyword into at least one H2 naturally, and use related terms and synonyms throughout — Google’s understanding of a topic comes from semantic coverage, not repetition of one phrase.
Answer the main query early, in the first paragraph, then go deeper. Short paragraphs, bullet lists and bolded key points make the page scannable and help with featured snippets. Cover the subtopics your competitors cover plus something they miss.
Keyword placement without stuffing
Place your focus keyword where it counts and then stop worrying about density:
- In the title tag and H1.
- In the first 100 words.
- In at least one subheading.
- In the URL slug (short and keyword-led, e.g.
/on-page-seo). - In image alt text where genuinely relevant.
- A few times in the body, plus natural variations.
Keyword stuffing now does more harm than good. Write for the reader first; modern on-page SEO is about comprehensiveness and clarity, not hitting a percentage.
Internal links and images
Link out to related pages using descriptive anchor text — this spreads authority and helps Google understand your site’s topic clusters. Link to your most important commercial pages from relevant articles. When we optimise content for clients through our SEO services, internal linking is often the fastest win on an otherwise solid site.
For images: compress them, use descriptive file names and alt text (which also helps accessibility), and set dimensions to avoid layout shift. Don’t keyword-stuff alt text — describe the image accurately.
Schema and on-page extras
Add relevant structured data — Article, FAQ, Breadcrumb, Product or LocalBusiness — so Google can render rich results. An FAQ section at the bottom of a page does double duty: it answers real questions and gives you snippet-eligible content. Keep URLs clean, ensure the page is mobile-friendly, and check it loads fast, since on-page SEO and page experience now work together.
A quick on-page SEO checklist
- Intent matches the format that ranks.
- Keyword in title, H1, first paragraph, one H2, URL.
- Comprehensive content that covers subtopics and questions.
- Scannable structure with short paragraphs and lists.
- Descriptive internal and outbound links.
- Optimised images with alt text.
- Meta description written for clicks.
- Relevant schema added and validated.
Refreshing existing pages
On-page SEO isn’t only for new content. Some of the fastest gains come from updating pages that already rank on page two. Pull your Search Console data, find pages sitting in positions 11–20, and treat each as a quick optimisation project:
- Re-check intent — has the type of result Google rewards shifted since you published?
- Expand thin sections and add the subtopics competitors now cover.
- Update statistics, examples and the year in the title where relevant.
- Add internal links from newer, stronger pages.
- Tighten the title and meta description to lift click-through.
Because these pages already have some authority and history, small improvements often move them onto page one faster than a brand-new article would climb. Make a refresh cycle part of your routine rather than a one-off.
Frequently asked questions
What’s the difference between on-page and technical SEO?
On-page SEO covers the content and elements of an individual page — titles, copy, headings, links. Technical SEO covers site-wide infrastructure — crawling, indexing, speed, structure. They overlap but on-page is about making each page relevant and useful for its target query.
How long until on-page changes show in rankings?
Google usually recrawls and reflects changes within days to a few weeks, depending on how often it crawls your site. Competitive keywords take longer to move because ranking depends on more than on-page factors. Request indexing in Search Console to speed up recrawling of an updated page.
Should every page target a different keyword?
Yes — each indexable page should have one clear primary keyword and intent. Targeting the same keyword on multiple pages causes keyword cannibalisation, where your own pages compete and dilute each other. Consolidate or differentiate them.
