To ensure the highest Google rankings, it will be enough to focus your efforts on just several main ranking factors.

The statement is false because Google's ranking algorithm is complex and incorporates hundreds of ranking factors. While some factors, like high-quality content, backlinks, and mobile-friendliness, are indeed very important, focusing on "just several" would be insufficient to achieve and maintain the highest rankings. A holistic approach considering technical SEO, user experience, content relevance, and authority signals is necessary. Neglecting other factors, even seemingly minor ones, can hinder overall performance and prevent a website from outranking competitors who optimize across a broader spectrum of factors.
