On-Page SEO vs. Off-Page SEO
On-page SEO deals with everything you control directly on your website. Off-page SEO is what happens beyond your site—backlinks, brand mentions, and digital PR. Both matter, but on-page optimisation is where every successful SEO campaign starts, because it's the foundation that makes off-page efforts worth anything.
| On-Page SEO | Off-Page SEO |
|---|---|
| Target keyword placement in content | Link building from external sites |
| Optimising title tags & meta descriptions | Guest blogging and content syndication |
| URL structure and slug optimisation | Digital PR and brand mentions |
| Internal linking architecture | Social media marketing |
| Page speed and Core Web Vitals | Influencer outreach |
| Schema markup (structured data) | Local SEO and citation building |
| Image alt text and file optimisation | Review generation |
Why On-Page SEO Matters More in 2026
Google's algorithms have grown dramatically more sophisticated. AI Overviews, featured snippets, and People Also Ask boxes now occupy the top of the SERP—meaning the page that answers questions most clearly and completely wins, regardless of domain authority.
In 2026, on-page SEO also directly influences AI answer visibility. Tools like ChatGPT and Perplexity cite pages that are well-structured, factually dense, and clearly authoritative. Neglecting on-page SEO means losing visibility not just on Google, but across the entire modern search ecosystem.
Across 200+ client campaigns, we've found that fixing on-page SEO alone increases organic traffic by an average of 43% within 90 days—before a single new backlink is acquired.
11 On-Page SEO Techniques That Actually Work
These are the exact techniques Brandstory's SEO specialists implement for every client. Work through them in order for maximum impact.
Write Unique, Search-Intent Content
Before optimising anything, you need content worth optimising. Google's Helpful Content system rewards pages that answer a query completely, from a place of genuine expertise. Matching search intent—informational, navigational, transactional, or commercial—is non-negotiable.
For any target keyword, study the top 10 results and ask: what format are they using? What sub-topics do they all cover? What do they miss? Your content should do everything the top results do, plus one or two things they don't—a proprietary data point, an original framework, a deeper explanation, or a concrete example drawn from real client experience.
- Match the content format to search intent (guide, listicle, comparison, tool page)
- Cover every sub-topic that appears across top-ranking pages
- Add one piece of unique insight, data, or example no competitor has
- Write for humans first—search engines reward genuine helpfulness
- Update content at least every 6 months to signal freshness to Google
Place Target Keywords Strategically
Natural keyword placement in the right locations tells both search engines and readers that your page is exactly what they're looking for. Stuffing keywords unnaturally does the opposite—it triggers Google's spam filters and alienates readers.
Place your primary keyword in these locations:
- H1 heading — the page's primary topic signal
- First 100 words — confirms relevance immediately
- At least one H2 subheading — reinforces topical depth
- URL slug — clean, descriptive, and keyword-rich
- Image alt text — where it fits naturally
- Meta title and description — covered in techniques 03 and 04
Also include semantically related terms (LSI keywords) throughout the body. These are words and phrases Google expects to find on a page about your topic. They strengthen topical relevance without artificial repetition.
Write a Relevant, Click-Driving Title Tag
The title tag is the HTML element that appears as the clickable blue link in Google search results. It's one of the strongest on-page ranking signals and your first opportunity to earn a click.
- Keep the title between 50–60 characters to avoid truncation in SERPs
- Include your primary keyword near the start of the title
- Add a benefit, number, or year to make the title compelling
- Write a unique title for every page—duplicate titles confuse Google
- Brand your titles consistently with " | Brandstory" at the end
Write an Enticing Meta Description
Meta descriptions are not a direct ranking factor, but they are a critical click-through rate factor. A compelling meta description is the difference between a user choosing your result or your competitor's.
- Target 100–110 characters to fit within Google's preview window
- Include your primary keyword naturally
- Use active voice: "Learn how to…" beats "This article is about…"
- End with a clear call to action: "See the full checklist" or "Start optimising today"
Structure Pages with Heading Hierarchy
Headings (H1 through H6) create the skeleton of your page. Google uses headings to understand content structure and extract answers for featured snippets and AI Overviews. Well-structured pages also keep users on-page longer—a behavioural signal that influences rankings.
- Use exactly one H1 per page containing your primary keyword
- Use H2s for major subtopics—think of them as chapter titles
- Use H3s for sub-points within each H2 section
- Make headings descriptive, not generic: "How to Conduct Keyword Research" beats "Getting Started"
- Answer the heading question in the first sentence below it—this is what AI tools extract
- Write each section so it can stand alone and make sense in isolation
LLMs like ChatGPT and Gemini scrape pages section-by-section. If your H2 asks a question and the first sentence below it directly answers it, you dramatically increase your chances of being cited in AI-generated responses.
Optimise Your URL Slug
URL slugs are a lightweight but real ranking signal. More importantly, a clean URL builds user trust—when someone sees a URL that matches their query, they're more likely to click.
- Keep slugs to 3–5 words maximum
- Include the primary keyword
- Use hyphens to separate words (never underscores or spaces)
- Remove stop words (a, the, and, of) unless they're necessary for clarity
- Avoid dates, session IDs, and auto-generated parameters
Build a Strategic Internal Link Architecture
Internal links serve two purposes: they help users navigate to related content, and they pass PageRank (link equity) between pages. A well-planned internal linking structure can dramatically improve rankings for pages that would otherwise struggle to rank on their own.
- Link new pages from existing high-authority pages on your site
- Use descriptive anchor text—"see our technical SEO guide" beats "click here"
- Link to relevant, topically related pages that genuinely help readers
- When publishing new content, always link back to it from related existing pages
- Avoid over-linking—3 to 5 strategic internal links per page is a healthy range
- Use a site crawl tool to find orphan pages with no internal links pointing to them
Add External Links to Build E-E-A-T
Outbound links to authoritative, relevant sources strengthen your page's credibility in the eyes of both readers and Google's quality raters. They signal that your content is backed by real evidence—a key component of Google's E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) framework.
- Link to government, academic, and industry-leading sources to support claims
- Use descriptive anchor text so readers know what to expect
- Limit outbound links to 2–5 per article—don't send readers away unnecessarily
- Avoid linking to direct competitors unless citing research
- Regularly audit external links to replace broken or outdated URLs
Optimise Every Image on the Page
Images contribute to rankings in three ways: descriptive alt text improves relevance, compressed file sizes improve page speed, and properly labelled images appear in Google Image Search. All three matter.
- Write alt text that describes the image in under 125 characters—include your keyword where it fits naturally
- Use descriptive file names:
on-page-seo-checklist.jpgbeatsIMG_4872.jpg - Compress all images before uploading—use WebP format for photos
- Use PNG for graphics with transparency; SVG for logos and icons
- Add explicit width and height attributes in HTML to prevent layout shifts (improves CLS)
- Implement lazy loading so off-screen images don't block initial render
Optimise Page Speed & Core Web Vitals
Page experience is a confirmed Google ranking factor. Core Web Vitals—Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS)—measure how fast and stable your page feels to real users. Poor scores cost you rankings, especially on mobile.
- Target an LCP under 2.5 seconds — the time your main content takes to load
- Serve images in modern formats (WebP, AVIF) and the right sizes for each device
- Use a CDN to reduce server response time
- Defer non-critical JavaScript to unblock the main render thread
- Preload critical fonts and above-the-fold images
- Measure with Google's PageSpeed Insights and fix issues in priority order
Add Schema Markup for Rich Results
Schema markup is structured data (in JSON-LD format) that you add to your page's HTML. It tells Google exactly what your content is about—an article, a product, a review, an FAQ—making you eligible for rich snippets that display extra information directly in the SERP and significantly boost click-through rates.
- Article schema — for blog posts and guides; shows author, date, and headline
- FAQ schema — displays expandable Q&As directly in the SERP
- Product schema — shows price, availability, and star ratings for e-commerce
- Local Business schema — shows address, hours, and contact info for location-based businesses
- HowTo schema — eligible for step-by-step rich results
- Validate all schema with Google's Rich Results Test before deploying
FAQ schema is one of the highest-impact, lowest-effort rich snippet types available. Add an FAQ section at the bottom of your key pages with 4–6 questions and implement the schema—Brandstory clients regularly see CTR increases of 15–25% from this alone.
