Before investing in content, links or advertising, it pays to know what you already have. An SEO audit is the full X-ray of your website: what is stopping it from ranking, what is wasting potential, and in what order it should be fixed.
What I deliver is not an 80-page PDF exported from a tool. It is a document with findings prioritized by impact and effort, explained in language you can act on, with a concrete instruction for each item. Your developer can pick it up and work directly from it; if you don't have anyone to execute, I can do that too.
