1. Conduct a Comprehensive Website Audit

A technical SEO audit identifies all issues affecting your website’s crawlability and indexing. Conducting regular audits ensures your site meets Google’s evolving algorithms, including BERT, SBERT, and NLP-based ranking factors.

Review Site Architecture

  • Ensure logical hierarchy and siloed structure.
  • Optimize internal linking to help search engines understand page importance.

HTTPS and Security Audit

  • Verify SSL certificate is installed properly.
  • Resolve mixed content issues to maintain user trust and ranking potential.

2. Improve Site Speed and Performance

Page speed is a confirmed ranking factor and directly impacts user experience, bounce rate, and Core Web Vitals.

Image Optimization

  • Compress images and use next-gen formats like WebP.
  • Include descriptive alt text for accessibility and SEO.

Set Canonical Tags

  • Ensure each duplicate or similar page points to a preferred canonical URL.

Use 301 Redirects

Redirect permanently duplicated content to the main version.

Robots.txt and Noindex Rules
