Conducting an SEO audit requires various tools and methods, but the process typically starts with crawling your website with a tool like Screaming Frog, Ahrefs, or Moz to collect data on your site's structure, pages, links, and meta tags. After analyzing your site's technical aspects such as speed, mobile-friendliness, security, and indexability, you should evaluate your content quality, relevance, and optimization. Make sure your content is aligned with target keywords, audience, and intent while avoiding issues like duplicate content or keyword stuffing. Additionally, you should analyze your site's off-page factors such as backlinks and social signals to assess its authority and trustworthiness. To improve your site's ranking, remove any toxic or spammy links and look for ways to earn more high-quality links from other sites. Finally, prioritize and implement the changes based on the impact and urgency of each issue before monitoring the results over time.
