The practice of using the same terms excessively on a webpage is known as "keyword stuffing." This is considered a "black hat" SEO tactic these days. As search engines have developed, they now recognise not just your keywords but also terms and phrases that are similar to or have a similar meaning to your keywords. This implies that writing more organically will still help you write effectively. The ideal strategy is to develop the content for each web page with the search intent that would lead the visitor in mind and stick to that one topic. Read aloud anything you're unsure of. You're most likely keyword stuffing if the website sounds artificial and repetitious!
