What is an SEO Audit?
An SEO audit is a comprehensive process of evaluating a website's search engine friendliness in several key areas. It involves analyzing technical SEO (like site speed, crawlability, and indexation), on-page SEO (content, keywords, and meta tags), and off-page SEO (backlinks and domain authority). The goal is to identify technical issues, content gaps, and strategic opportunities to improve search engine rankings, drive more organic traffic, and increase overall website performance and ROI.
