You do not need expensive tools to get started with SEO. Google provides several free options that give you valuable insights into your performance. Google Analytics shows you where your traffic comes from, while Google Search Console helps you understand how Google views your site.
Keyword tools help you see what people search for and how competitive those terms are. Audit tools scan your site to reveal broken links, slow pages, or missing tags. Start with the basics, learn how your site performs, and add advanced tools over time.
