Can I do my own SEO audit?

Yes, a basic SEO audit is doable yourself using free tools. Google Search Console shows indexing and keyword data directly, and Screaming Frog's free tier crawls up to 500 URLs at no cost.

What is harder to self-assess is prioritization, deciding which of dozens of flagged issues actually matter for your specific site and business goals, since not every technical issue affects rankings equally.

A reasonable approach is running the free tools yourself first, then bringing in outside help only if the findings are overwhelming or the fixes require technical skills you do not have.

Once you know what content is missing, an SEO automation platform can start filling those gaps automatically.
