1. What Is an SEO Audit?
An SEO audit is a detailed review of different parts of a website that influence its ability to be discovered, crawled, indexed and understood by search engines.
It can reveal issues such as broken links, missing page titles, slow-loading pages, duplicate content and indexing problems.
2. Check Website Indexing
First, check whether Google can discover and index your important website pages. You can use Google Search Console to inspect indexing information and identify pages with problems.
You can also search Google using:
site:example.com
Replace example.com with your own website address. This search can show some pages Google has indexed, but it is not a complete indexing report.
3. Review Technical SEO
Technical SEO helps search engines access and understand your website. Review these important areas:
- HTTPS: Make sure your website uses a secure connection.
- Mobile friendliness: Check that pages work properly on mobile devices.
- Page speed: Review loading performance and Core Web Vitals.
- XML sitemap: Make sure your sitemap contains valid, important URLs.
- Robots.txt: Check that important pages are not accidentally blocked.
- Broken links: Find links that lead to missing pages.
- Redirects: Check for unnecessary redirect chains and incorrect redirects.
4. Check On-Page SEO
On-page SEO means improving the content and HTML elements of individual pages. Review each important page for:
- A unique and descriptive page title.
- A useful meta description.
- One clear main heading (H1).
- Logical H2 and H3 headings.
- Relevant keywords used naturally.
- Descriptive image alt text.
- Helpful internal links to related content.
5. Review Content Quality
Good content should answer the reader's question clearly. Check whether your articles provide useful information, accurate explanations and practical examples.
Look for outdated information, thin pages, repeated content and articles that do not satisfy the searcher's intent. Improve or combine pages when doing so genuinely helps readers.
6. Analyze Backlinks
Backlinks are links from other websites pointing to your website. Review whether your website receives relevant links from trustworthy sources.
Focus on earning links through useful resources, original research, quality content and genuine relationships. Avoid buying spam links or participating in link schemes.
