Local SEO audit, what does your actual process look like from start to finish?

Been trying to standardize my local SEO audit process across clients and i keep finding gaps depending on the business type.

What i check for a multi-location retail chain is pretty different from what matters for a single location service business.

I have a checklist covering GBP, citations, on page local signals, reviews, and backlinks. but i feel like i'm missing a layer of competitive analysis and local pack specific diagnostics that would make the audit more actionable.

What does your local SEO audit process actually look like? and are there specific things you check that most people overlook when auditing local search presence?
