On-page SEO means the things you control on a single page: its title, headings, text, images, URL and links. Get these right and Google, and your visitors, understand the page faster.
This guide covers seven page elements. It is about one page at a time. For site-wide work such as crawling and speed, see the separate guides linked below.
On-page SEO is the work you do on each page. Write a clear title and a unique meta description, use headings to organise the text, answer the visitor’s question, describe images with short file names and alt text, use a readable URL and link to related pages with clear anchor text. Google gives no formula, but these steps follow its own documentation.
⚡ Key Takeaways
- Google says there is no limit on title length, but the title link is truncated to fit the device width.
- Google may use the meta description as the snippet when it describes the page better than the page text.
- Google advises a unique description for each page, not the same one site-wide.
- Alt text helps people who cannot see the image, and Google uses it to understand the image.
- Google recommends readable words in URLs and hyphens between words.
1. Write a Clear Title for On-Page SEO
Google says the title element should be descriptive and concise. It also warns against vague titles such as “Home” and against keyword stuffing. Each page needs its own title.
Put the main topic first and keep it readable. For more ideas, see these tips for writing blog titles.
2. Add a Unique Meta Description
A meta description is a short summary of the page. Google says it may use it as the snippet if it describes the page better than the text itself. It may also write its own snippet instead.
So, write one accurate sentence or two for every page. Google says identical descriptions on every page are not helpful, so avoid copying one across the site.
3. Use Headings in On-Page SEO to Organise the Page
The SEO Starter Guide suggests breaking long content into sections and giving each a heading, so visitors can find their way. Use one main heading for the page topic and sub-headings for each part.
Also, write headings the way a visitor would phrase the question. They read better, and they make the page easier to scan.
4. Answer the Visitor’s Question
Its systems prioritise helpful, reliable content made for people. So start by checking what the searcher wants, and answer it clearly near the top of the page.
For the full workflow, here are the steps to write an SEO-friendly blog post.
5. Describe Your Images for On-Page SEO
For images, it advises short but descriptive file names, so my-new-black-kitten.jpg is better than IMG00023.JPG. Alt text should describe what the image shows. It also helps people who use screen readers.
Place images near the text that relates to them. Large files slow the page down, so compress them first. These free image compression tools can help.
6. Use a Readable URL
Moreover, it recommends readable words instead of long ID numbers, and hyphens instead of underscores to separate words. A short URL that describes the page is easier to share and to understand.
Once a page is live, avoid changing its URL without a redirect. This guide to WordPress permalinks explains the options.
7. Link to Related Pages with Clear On-Page SEO Anchors
Also, link text tells people and Google something about the page you link to. It can only follow links that are normal <a href> elements, so use those.
Link from each page to related pages on your own site. Spreading internal links sensibly helps both visitors and crawlers.
A Made-Up Example
Imagine a bakery page titled “Home” with the URL /page?id=482. The owner changes the title to “Custom Birthday Cakes in Leeds”, writes a short description, and adds headings for flavours, sizes and ordering.
Next, she renames the cake photos, adds alt text and links to her delivery page. None of this guarantees a ranking. It does make the page clearer for people and for Google. The example is invented.
