It is good to pay attention to technical aspects when you’re doing SEO, but ignoring them wouldn’t be a big mistake.

This statement is false because ignoring technical SEO aspects is a significant mistake. Technical SEO ensures search engines can effectively crawl, index, and understand your website. Issues like slow page speed, broken links, improper sitemaps, or non-mobile-friendly designs can severely hinder your site's visibility and ranking, even if your content is excellent. A technically sound website provides a strong foundation for all other SEO efforts, improving user experience and search engine accessibility. Without addressing these foundational elements, content optimization and link building may have limited impact.
