1. Technical SEO Audit

• Check Website Indexability: Use Google Search Console to index your pages properly. Look for crawl errors and fix them.
  
• Analyze Website Speed: Use tools like Google PageSpeed Insights, GTmetrix, or Lighthouse to assess load times and optimize them.

• Verify HTTPS and Security: Make sure your site uses HTTPS and has a valid SSL certificate.
  
• Check XML Sitemap & Robots.txt: Ensure your sitemap is updated and submitted to search engines while reviewing robots.txt for accidental blocking.
  

2. On-Page SEO Audit

• Optimize Title Tags & Meta Descriptions: Ensure they are unique, keyword-rich, and within the recommended character limits.

• Optimize for User Intent: Make sure your content aligns with what users are searching for.
  

4. Off-Page SEO Audit

• Analyze Backlink Profile: Use Ahrefs, Moz, or SEMrush to check backlink quality and remove toxic links.
  
• Monitor Brand Mentions: Engage with users mentioning your brand and convert unlinked mentions into backlinks.
  
• Assess Competitor Backlinks:  Identify and replicate high-quality links from competitors.
