The On-Page SEO Checklist for a New Blog Post
On-page SEO is the work you can see in the page itself. This checklist is designed for the last hour before publishing, when you want confidence without turning a useful article into a spreadsheet exercise.
Table of Contents
1. Confirm the page has one clear job
Read the draft title and first paragraph together. Can you tell who the page serves, what it answers, and what a reader can do with the information? If the article is trying to answer three unrelated questions, split it or make the primary job explicit. Focus is a quality signal for people before it is anything else.
2. Check the information architecture
- Use one H1 for the page’s main topic.
- Use H2 headings for the major steps or questions.
- Use H3 headings only when a section genuinely needs another layer.
- Make headings descriptive enough to work as a quick scan.
- Keep paragraphs short enough for a phone screen.
Headings are not just large text. They form a table of contents for a reader who is deciding where to spend their attention. A heading like “A few thoughts” is pleasant but invisible; “Choose a primary keyword from a real customer question” tells the reader exactly what follows.
3. Make internal links do a real job
Add links where the reader is likely to need background, an example, or a next action. Use anchor text that describes the destination: “learn how to choose a page title” is more useful than “click here.” One strong link is better than five links added only to increase a count.
The Internal Link Suggestion Tool can help you spot connections in a longer draft, but keep the final choice editorial. A link should make the reader’s next step easier.
4. Give images a purpose
Compress large images, use a descriptive filename, and write alt text that conveys the image’s meaning in context. If the image is purely decorative, an empty alt attribute is often more honest than a keyword-filled sentence. A diagram may need a longer explanation in the body rather than an overloaded alt attribute.
Use the Image Alt Text Generator as a starting point for accurate, human-readable descriptions. Review the result against what is actually visible in the image.
5. Finish the technical edges
- Write a unique title and meta description.
- Choose a short, readable URL and avoid changing it casually after publishing.
- Set a canonical URL when the same content can be reached through multiple addresses.
- Confirm the page works on a narrow screen and does not hide the answer behind a pop-up.
- Add Article or other appropriate structured data only when it reflects the visible page.
A canonical tag is a hint about the preferred URL, not a way to merge unrelated pages. Structured data is similar: it describes what is already there. Neither makes a thin page useful. Finish the human experience first, then use technical signals to remove ambiguity.
When the page is ready, the SEO Audit Checklist gives you one final place to record what passed and what needs a later improvement.
Publish, then listen
The checklist ends at publication, but the work does not. Revisit the article when you have evidence: questions from customers, search queries in your analytics, or a new example that makes a confusing section clearer. Good on-page SEO is a living relationship between the promise in the result and the usefulness of the page.
