1. Why On-Page SEO Matters for Conversions
Understanding On-Page SEO Optimalisatie
On-page SEO is the process of optimizing the content and structure of your website to improve its visibility in search engines. Unlike off-page SEO, which focuses on building backlinks and external signals, on-page SEO involves everything you can control directly on your website. This includes optimizing content, HTML tags, user experience (UX), and other elements that influence how search engines and visitors perceive your site.
Why does on-page SEO matter for conversions? Because search engines reward websites that are user-friendly, fast, and contain high-quality, relevant content. By focusing on optimizing your web pages for both search engines and users, you not only improve your chances of ranking higher but also increase the likelihood that visitors will take action—whether it’s making a purchase, filling out a form, or subscribing to your newsletter.
2. Content Optimization: Creating Valuable, Engaging Content
Focus on User Intent and Quality
In 2025, optimizing your content for user intent is the key to ranking higher and driving more conversions. Google’s algorithms are now more advanced than ever, and they prioritize content that satisfies the needs of users. Your content must not only be relevant to the keywords you’re targeting but also comprehensive, engaging, and useful to your audience.
Tip: Research your target audience’s questions, pain points, and interests. Craft content that directly addresses these areas while providing in-depth, valuable information. Avoid thin or shallow content—Google rewards long-form, well-researched, and unique content.
Use Keywords Naturally and Avoid Stuffing
While keywords are still important for SEO, the days of keyword stuffing are long gone. Google’s algorithms now understand context and relevance, so simply throwing in keywords doesn’t work anymore. It’s about using keywords naturally within your content to ensure that the page is contextually relevant to the search query.
Tip: Focus on semantically related keywords, and use them in a natural and user-friendly way. Incorporate them in headings, subheadings, and body text, but ensure your content reads well and isn’t forced.
3. Enhancing User Experience (UX) for Higher Conversions
Core Web Vitals: Google’s Focus on UX
In 2025, Google’s Core Web Vitals and overall user experience are crucial for both rankings and conversions. A well-designed, user-friendly website can significantly impact how visitors interact with your content. Page load speed, interactivity, and layout stability are now key factors for SEO success.
Tip: Focus on improving the loading time of your web pages by optimizing images, leveraging browser caching, and minimizing the use of large files. Tools like Google PageSpeed Insights can help you identify areas for improvement.
Mobile-First Indexing: Prioritize Mobile Optimization
With mobile-first indexing, Google primarily uses the mobile version of your website for ranking and indexing. This makes mobile optimization a crucial part of on-page SEO. A website that’s not optimized for mobile users will not only have poor search rankings but also suffer from lower conversions.
Tip: Ensure your website is fully responsive and provides a seamless experience on mobile devices. Test your website across various devices to ensure smooth navigation and usability.

4. EEAT: Establishing Expertise, Authoritativeness, and Trustworthiness
Building Trust with High-Quality Content
EEAT (Experience, Expertise, Authoritativeness, and Trustworthiness) is an increasingly important factor in SEO for 2025. Websites that demonstrate expertise and authority are more likely to rank higher in competitive industries, especially in YMYL (Your Money Your Life) sectors such as health, finance, and law.
Tip: To establish EEAT, ensure your content is written by experts or reviewed by authoritative figures in your field. Include references to credible sources and regularly update your content to reflect the latest industry knowledge.
Showcasing Authoritative Backlinks
While backlinks are generally considered off-page SEO, they still contribute to your on-page efforts. When authoritative websites link to your content, it signals to search engines that your site is trustworthy and valuable. This can improve your rankings and, ultimately, your conversions.
Tip: Focus on earning backlinks from reputable websites and publications. Guest posting and content partnerships are great ways to build your site’s authority.
5. Outdated SEO Techniques to Avoid
Keyword Stuffing and Low-Quality Content
Keyword stuffing and low-quality content used to be common practices in SEO, but these tactics are no longer effective. In fact, Google now penalizes over-optimized content that is stuffed with irrelevant or excessive keywords.
Tip: Avoid over-optimization. Write for people first and search engines second. Create content that is relevant, valuable, and engaging.
Buying Backlinks
While backlinks are important for SEO, buying links from low-quality or irrelevant websites can harm your rankings. Google’s algorithms have become better at detecting spammy backlinks, and these practices can lead to penalties.
Tip: Build backlinks organically by creating high-quality, shareable content and forming relationships with influencers and authoritative sites in your industry.
