To rank higher on SERP requires consistent effort. It starts from understanding the Google search and ranking algorithm, knowing the current ranking of your website, establishing the right metrics to track and measure results, ensuring the website is mobile-friendly, doing keyword research, improving on-page SEO optimization, using keywords to create content, and building the links in the right way.
You can also consider using a pay-per-click ad campaign to come to the top of SERP.
