## Purpose of an audit

Identify technical and on-page SEO issues, and check crawlability, speed,
and indexation status.[^iskills-course-notes]

## Types of audits

1. **Manual audit** — thorough but labour-intensive, checked by hand.
2. **Tool-based audit** — faster and scalable across many pages at once.

## Recommended tools

- Screaming Frog
- Sitebulb
- Ahrefs Site Audit
- SEMrush Site Audit

## Screaming Frog

Crawls a website the way a search-engine bot would, and checks for:

- Broken links
- Redirects
- Duplicate titles and descriptions
- Missing alt tags
