How These Free SEO Tools Help With SEO Audits

A website SEO audit can involve hundreds of individual checks. You do not always need a complex platform to investigate a specific problem.

Focused tools can help you break an audit into smaller tasks.

1. Check technical URL issues

Start by checking your important URLs and their HTTP status codes. This can help you identify broken pages, unexpected redirects, and server errors.

2. Review on-page SEO

Check whether important pages have appropriate titles, meta descriptions, headings, and other basic on-page elements.

3. Turn existing content into usable text

If your content exists primarily in video or audio format, transcription can make it easier to analyze, repurpose, and develop into written content.

4. Combine individual checks

An SEO audit is not based on one metric. Use different checks together to build a clearer picture of your website’s technical and content health.
