Once Google can find and index your website — which we covered in how SEO works for beginners — the next question is simple: how do you tell Google what each page is actually about? That is the job of on-page SEO.

On-page SEO is everything you control directly on a page: the title, the headings, the words, the links, and the images. Get it right and you make Google's job easy — and a page Google understands clearly is a page it can rank confidently. In this guide (and the video above) I'll walk through each element, in the order you'd actually work through them. New to SEO? Start with the SEO basics guide.

What Is On-Page SEO, Really?

On-page SEO is the practice of optimising individual pages so both people and search engines understand them. It sits between two other disciplines: keyword research, which tells you what a page should be about, and technical SEO, which makes sure Google can reach the page in the first place. On-page is where you turn a target keyword into a page that deserves to rank.

There are six elements worth getting right. None of them is complicated on its own — the results come from doing all of them, consistently, on every page.

1. Meta Titles & Descriptions

Your meta title and description are the first impression in the search results — often before anyone visits your site at all. The title is a genuine (if minor) ranking signal and the single biggest factor in whether someone clicks. The description doesn't affect ranking directly, but a strong one lifts your click-through rate, which is itself a positive signal.

Front-load your main keyword near the start of the title, then add your brand at the end for authority — separated with a pipe, like On-Page SEO for Beginners | yourseoebook.com. For the description, write for a real person, include the keyword naturally, and add a gentle call to action such as "learn how" or "get the checklist".

2. Heading Structure (H1–H3)

Headings are the skeleton of your page. They break content into sections that are easy to scan, and they tell Google how your ideas are organised. The rules are short:

Use exactly one H1 per page — your main title, containing your primary keyword. Use H2s for your main sections and H3s for sub-points inside them. Follow a logical order and never skip a level (don't jump from an H2 straight to an H4). Think of it like a table of contents: an H3 always lives inside an H2.

3. Page Content & E-E-A-T

Content is where rankings are won. Google tells us directly that helpful, reliable content is a core ranking factor, and it evaluates quality through E-E-A-T — Experience, Expertise, Authoritativeness and Trustworthiness. In plain terms: show that a real person with real knowledge wrote this, cover the topic properly, and give people a reason to trust you.

4. Internal Linking

Internal links guide readers to related pages and help Google discover and understand how your content connects. A page with no links pointing to it is like a room with no door — crawlers may never reach it. Link from relevant pages using descriptive anchor text that says what the destination is about (for example, "keyword research for beginners" rather than "click here"). This single habit spreads authority around your site and keeps people reading. For the full picture, work from the complete SEO checklist.

5. Images & Alt Text

Images make content easier to follow and give you another way to be understood. Use descriptive file names, write meaningful alt text that describes what the image shows, save in modern formats like WebP, and size images responsively so they don't slow the page. Alt text also makes your content accessible to people using screen readers — a win for everyone, not just SEO.

6. Bring It Together With a Checklist

On-page SEO is a routine, not a one-off. Every time you publish or update a page, run through the same elements: one clear keyword, a strong title and description, clean headings, genuinely helpful content, sensible internal links, and optimised images. For a full page-by-page routine you can reuse, work from the SEO checklist.
