I think the best approach is to focus on solving a specific problem for your users first rather than trying to rank for too many keywords at once. Do keyword research first, review websites that are already ranking on Google, and make sure your website is fast, easy to use, and easy to navigate. To rank for a tool-based website, you need to focus on SEO, find keywords that have low competition for your tools, keep your website speed up, write good titles and descriptions for each tool, and include blogs or guides for your users. Once your site is indexed on Google and people are using it, traffic will start to grow on its own.
