DIY SEO Site Audit: Your 12-Point Checklist for Organic Growth

You don’t need a fancy agency or a five-figure budget to improve your SEO. What you do need is a smart, simple checklist that shows you where your site stands and how to fix what’s broken.

Whether you’re running a WordPress site, Shopify store, or something in between, this DIY audit will help you spot the issues that are quietly killing your rankings.

Let’s get into it. 💻📈

Why Every Small Business Needs an SEO Audit

Search engines don’t rank websites – they rank pages. And if those pages are slow, confusing, or invisible to crawlers, your traffic’s going nowhere.

An SEO audit is your chance to clean up technical issues, optimize what’s working, and unlock free traffic over time.

How to Use This Checklist

You can run through all 12 steps manually, or download the free audit sheet at the end of this post to track your results. Each step includes a quick fix or tool recommendation. No fluff, no wasted time.
