Have you ever wondered why some sites place in the first few results in Google, while others, which even have a better service or product, place on page 5? The answer to this is almost always on-page SEO.
In digital marketing, on-page SEO is the foundation. It doesn’t matter how many backlinks you create, how much you spend on ads, or how active you are on social media if you don’t optimize your web pages. You’ll lose traffic to competitors. You’ll learn all you need to know about on-page SEO in this ultimate guide, the importance of on-page SEO, and how to implement on-page SEO, even if you are a complete beginner.
What is On-Page SEO?
All the changes you make on your website to better the rankings on search engines and to help search engines better understand your website are called on-page SEO. Unlike off-page SEO, which covers all the external activities like backlinking, on-page SEO covers things that are entirely in your control.
These are:
- Meta descriptions and Title tags
- H1s, H2s, H3s, etc.
- Placement of keywords
- URLs
- Links
- Images and their Optimizations
- The overall speed and friendliness of a page on mobile
- Readability and the quality of content
- Schema markups
Let’s discuss these in more detail.
- Keyword Research: The Foundation
It’s important to know what your audience is searching for before putting anything down on paper. This is what keyword research is for.
While looking for keywords in Semrush, Ahrefs, or Google Keyword Planner, keep in mind the following:
- Primary keywords: The word or phrase you wish to center your content around (e.g. the “on-page SEO checklist”).
- Secondary keywords: Words that support your primary word (e.g. “meta tags,” “internal linking,” “SEO content writing”).
- Long-tail keywords: Keywords that are more specific and maybe searched less, but have more intent (e.g. “on-page SEO tips for small business websites”).
You should look for keywords that have a decent amount of searches and are not super easy, but still somewhat simple to rank for. This is especially true if your website is somewhat new.
- Create Titles That Users Can’t Resist
Your title hits users and Google first in search results. To be effective, your title should:
- Center around your primary keyword, and ideally be at the start.
- Stay within 60 characters, or else it’ll be cut off.
- Be compelling enough to encourage users to click.

Meta Descriptions That Convert
Meta descriptions don’t impact search positioning, but they can influence your click-through rate (CTR). Google considers CTR over time.
For your meta description:
- Aim for 150-160 characters.
- Include a clear reward for clicking, such as “Learn how to…” or “Discover the…”.
- Include your target keyword.
Header Tags (H1, H2, H3) Structure
Search engines/Rankings use header tags to analyze the structure and hierarchy of your content. Here are some more tips to consider:
- Include just one H1 per page (main title).
- Major sections of your content should be H2s.
- Use H3s for sub-points.
- Headers should include keywords, but make sure they flow naturally.
Well-structured pages make it easier to find for both Google and your visitors.
URL Structure
SEO prefers clear and descriptive URLs. Instead of yoursite.com/page?id=12345, use yoursite.com/on-page-seo-guide. Short URL structures with keywords help both search engines and users understand the content of the page.
Internal Linking
Search engines need help crawling your site. Internal links also help visitors discover more content you have. Create your blog posts/pages and:
- Link to 2-4 other relevant pages or posts.
- Use descriptive anchor text that accurately represents the content of the linked page. Do not use the generic phrase, “click here.”
- In the design of your website, ensure that all key pages are included within a few clicks of the homepage.
- Image Optimization
Images help enhance the beauty of your website, but they also can help your search engine positioning and the speed of your individual pages. To help in all these areas use the following:
- Compress your images prior to uploading using any one of the many free tools available online.
- Use descriptive file names, for example, use “on-page-seo-checklist.png” not “IMG_1023.png.”
- Add alt text for each one of your images. This text helps describe the image and is very important for accessibility. This text can also aid in your image search ranking.
- Page Speed & Mobile Friendly
With the initiation of mobile first indexing, Google has begun using the mobile version of your website to determine ranking and has paired this with Core Web Vitals which has made page speed a direct ranking factor.
To improve the speed of your website, try these tips:
- Use a lightweight theme for WordPress.
- Add a caching plugin.
- Compress all your images.
- Reduce the number of unnecessary plugins and scripts.
- Content Quality & E-E-A-T
When ranking websites, Google places the highest level of importance on content that demonstrates Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T). The following tips will help you with this content:
- Create content that is in-depth, original, and comprehensive in answering the user’s query.
- Do not create ‘thin’ content or content that is duplicated from other sources.
- Include the author’s credentials and case studies.
- Stay current and relevant by refreshing or revising previous articles.
- Schema Markup
Schema markup, or structured data, assists search engines in better comprehending your content. This can lead to rich snippets in search results, like star ratings, FAQ results, or recipe cards. If you’re using WordPress, the Yoast SEO or Rank Math plugins assist you in integrating basic schema without coding.

On-page SEO is a continual challenge. This is because Google develops and releases new algorithms constantly, competitor content is ever-optimized, and user behavior is dynamic. However, the first time is always the most difficult and tedious. Following that, habit, and routine establish. Following the above checklist will help optimize each post and page.
