On-page SEO is the process of optimising both your website content and the HTML code behind it. It covers everything you do directly on a webpage to help search engines understand your content better and improve visibility.
If you’re aiming to rank higher on Google, using a proper on-page SEO checklist is a must. These techniques improve your page rankings, increase user engagement, and drive more organic traffic.
In this article, you’ll discover a beginner-friendly step-by-step guide and on-page SEO checklist to help you get started the right way.
What is On-Page SEO?:
On-page SEO is the process of optimizing both the content and the HTML code of your webpage. It helps search engines understand your content clearly and improves your website’s visibility in search results.
This process also brings more organic traffic by making your page user-friendly and well-structured. On-page SEO includes content optimization, HTML adjustments, and image optimization, all of which work together to improve your page’s performance for users and search engines.
Why is On-Page SEO Important?:
On-page SEO is all about optimizing your webpage’s content and HTML structure to boost search engine visibility. When your content is well-structured and optimized, it becomes easier for search engines like Google to index and rank your pages accurately.
Good on-page SEO also improves the user experience by making your website easy to read, navigate, and engage with. This can lead to higher click-through rates, longer time spent on your site, and increased chances of conversions.
In short, on-page SEO helps both search engines and users, making it a powerful tool for improving your site’s visibility, traffic, and overall performance.
On-Page SEO Checklist:
To properly optimize your webpage, you need to follow this on-page SEO checklist. By applying each item in the checklist, you can improve your page’s visibility and rankings in search engine results. Let’s explore the basic on-page SEO activities that contribute to better visibility and ranking.
1. Title Tag:
Your title tag should clearly describe the content of your webpage using short and meaningful words. Keep it within 50 to 60 characters. Make sure to include your main keyword, and write it in a catchy and engaging way so users feel encouraged to click on your page when they see it in search results.
2. Meta Description:
Your meta description should clearly summarize the content of your webpage. It’s good to include your main keyword, but it’s not mandatory. You can also use related or secondary keywords. Try to keep the description between 150 to 160 characters to ensure it displays properly in search results.
3. URL Structure:
Keep your URL short, clean, and easy to understand. It should include your main keyword and avoid special characters, numbers, or spaces. Use HTTPS for secure browsing and ensure your URL is mobile-friendly. Also, make sure each URL on your website is unique and not repeated.
4. Headings (H1, H2, H3…):
Use H1 for the main title of your page, and use H2 for important sections. For sub-sections, use H3 and H4 headings. Add your main keyword in the H1 and H2 tags, and include secondary or related keywords in H3 and H4 tags. You can also use semantic keywords in your headings to help search engines better understand what your content is about. This improves your chances of ranking higher in search results.
5. Keyword Placement:
Keywords play a crucial role in helping your webpage rank higher in search engine results. But it’s important to place them strategically. If you overuse a keyword in one place or repeat the same keyword too often (known as keyword stuffing), search engines may treat your content as spam.
Here’s where you should focus on placing your keywords:
- URL – Include the primary keyword.
- Title Tag – Use the primary keyword (preferably at the beginning).
- Headings – Use the main keyword in H2, and place secondary or semantic keywords in H3 or H4.
- Introduction and Conclusion – Add your main keyword naturally.
- Body Content – Spread broad and long-tail keywords naturally throughout the content.
- Meta Description – Include the main keyword for better visibility.
- Image ALT Tags – Add keywords that are relevant to the image and the content, to help your images rank in image search.
Placing your keywords thoughtfully helps search engines understand your content better and improves your chances of ranking well without triggering spam filters.
6. Image Optimization:
With rapid advancements in technology, image optimization has become even more important in SEO. Today, search engines like Google not only rank webpages but also analyze image content through image search, AR, and VR technologies. That’s why optimizing images properly can significantly boost your page’s visibility.
Start by using high-quality images that clearly highlight your product or topic. Your image file name should be short, descriptive, and relevant to the content. Next, use ALT tags to describe what the image shows. These tags should clearly explain the image and also include keywords related to your content. This helps search engines understand your image and can improve your chances of appearing in image search results.
To improve page loading speed, always use compressed images with low file sizes. The image format you choose also matters:
- WebP – Preferred format. Offers high quality with low file size and no quality loss during compression. Best for SEO.
- JPEG – Small file size but lossy compression, which may reduce image quality.
- PNG – Maintains high quality with lossless compression, but usually results in larger file sizes.
Use WebP whenever possible, as it saves space and loads faster without losing quality.
Also, implement lazy loading so images only load when users scroll to them. This improves your page speed and enhances the overall user experience.
7. Internal Linking:
Internal linking means linking from one page on your website to another relevant page within the same site — like connecting your blog post to a related article or a product landing page.
This practice helps search engines crawl and index your website more efficiently, improving your site’s SEO. At the same time, it offers a better user experience by guiding visitors to more valuable information or encouraging actions like reading more or making a purchase.
By properly placing internal links, you’re:
- Helping users easily navigate your website
- Increasing the time they spend on your site
- Spreading page authority across your content
- Supporting better rankings for linked pages
Always link to relevant and helpful content naturally within your text, and use descriptive anchor text instead of generic phrases like “click here.”
8. External Linking:
External linking means adding links from your webpage to other websites that are relevant, high quality, and trustworthy. These links help search engines understand that your content is well researched and connected to reliable sources.
By linking to authoritative websites, you build credibility and improve your page’s trust factor in the eyes of Google. It also adds more value to your readers by guiding them to in-depth resources or supporting information.
Best practices include:
- Link only to relevant and reputable sites
- Avoid linking to low quality or spammy pages
- Use natural anchor text instead of writing “click here”
- Open external links in a new tab so users stay on your site
Adding external links shows that your content is part of a larger, trustworthy web ecosystem and that helps your SEO.
9. Mobile Friendliness and Page Speed:
These days, most users search for content on mobile devices rather than desktops. That is why your website must be fully responsive and work smoothly on all screen sizes.
In addition to mobile compatibility, your website should load quickly. A fast-loading page improves the user experience and helps your site rank better in search results.
To check your website’s loading speed and mobile performance, you can use tools like Google PageSpeed Insights. It will give suggestions to improve your page speed and overall mobile usability.
Focus on:
- Using a responsive design
- Minimising heavy scripts or plugins
- Compressing images
- Reducing unnecessary code
A mobile friendly and fast website keeps visitors engaged and improves your SEO performance.
Best Practices to Improve On-Page SEO:
To improve the on-page SEO of your website, follow these important best practices:
1. Use Schema Markup:
Add schema markup to your webpages. This helps search engines better understand your content and can improve how your pages appear in search results, including rich snippets.
2. Avoid Keyword Stuffing:
Do not overuse keywords. Repeating the same keywords too many times can make your content look unnatural and may lead to lower rankings.
3. Maintain a Clear and Structured Layout:
Your content should be well organised and easy to read. Use proper headings, short paragraphs, bullet points, and spacing to improve readability and user experience.
4. Follow Google’s E-E-A-T Guidelines:
Focus on building Experience, Expertise, Authority, and Trust through your content. Share helpful, reliable, and accurate information that proves you understand the topic well.
Following these best practices will help improve your search visibility and build trust with both search engines and your users.
