Type your website address into a free SEO checker and within a minute you will have a score out of 100, a few red warnings and a suggestion to upgrade for the full report. It feels useful, and sometimes it is. But we regularly speak to business owners who have a score in the 90s and almost no enquiries from search, and others with a mediocre score who do very well.
That gap exists because free audits measure what is easy to measure automatically. The things that really decide whether you get found, and increasingly whether AI tools cite you, often need a human to look at them in context.
What free SEO audits do well
Let us give credit where it is due. Automated tools are quick, consistent and good at spotting technical basics, including:
- Missing or duplicate page titles and meta descriptions
- Broken links and redirect chains
- Images without alt text or with huge file sizes
- Slow loading pages and Core Web Vitals warnings
- Missing HTTPS, sitemaps or robots.txt files
- Multiple H1 headings or missing headings
If you have never looked at any of this before, running a free audit is a sensible first step. Fixing obvious technical faults rarely hurts. If you are on WordPress, our guide to getting started with WordPress SEO covers many of these basics.
What automated audits miss
Whether you are targeting the right searches
A tool can tell you a page has a title tag. It cannot tell you that the title targets a phrase nobody in your area searches for, or that you are competing for a national term when your customers search with a suburb name. Keyword and intent mismatch is one of the most common problems we see, and it never appears on a free report.
Content quality and usefulness
Automated checks count words and look for keywords. They cannot judge whether your service page actually answers a customer's questions, whether it is more helpful than a competitor's, or whether it reads like it was written by someone who knows the trade. Search engines and AI systems increasingly reward that kind of usefulness.
Priority and business impact
Free reports list problems with little sense of proportion. A missing alt tag on a decorative image sits alongside a misconfigured canonical tag that is hiding your best page from Google. Without prioritisation, owners often spend hours fixing trivial warnings while the real issue remains.
Site architecture and internal linking
How your pages connect, which pages carry the most authority, and whether your important services are buried three clicks deep are structural questions. They require understanding what the business wants to rank for, not just crawling the URLs.
Local search signals
For most Australian small businesses, local visibility matters more than anything. That includes your Google Business Profile, consistency of your name, address and phone number across directories, reviews, and location pages that are genuinely useful rather than copy and paste. Most free website audits do not look at these at all.
AI search visibility
This is the newest blind spot. Free tools rarely check whether AI crawlers can access your site, whether your content is structured in a way AI systems can quote, or how ChatGPT, Perplexity and Google AI Overviews currently describe your business. We explain why this matters in how AI search engines choose sources and what is AI citability.

What a good professional audit should include
Not all paid audits are equal. Some are just a free tool's output with a logo on top. When comparing options, look for:
- A technical review that explains which issues matter and why.
- Analysis of the searches your customers actually use, including local variations.
- A review of your key pages against the competitors who outrank you.
- Checks of your Google Business Profile and local listings.
- An assessment of AI crawler access, structured data and how AI tools currently present you.
- A prioritised list of fixes, ideally split into quick wins and longer term work.
- Plain English explanations you or your developer can act on.
Be wary of audits that promise guaranteed rankings or arrive with a lengthy monthly retainer attached by default. A good audit should be useful on its own, whether or not you hire the auditor afterwards.
Which one do you need?
It also helps to think about the cost of doing nothing. If your website is meant to bring in a few new customers a month and it is not, the lost work over a year usually dwarfs the price of a proper audit. On the other hand, if most of your work comes through referrals and repeat clients, a free tool plus a few hours of tidying may be all you need. Be honest about how much search matters to your business before deciding how much to spend on it.
If you are just curious, or your website is brand new, start with a free tool and fix the obvious things. If search is meant to be a real source of customers and it is not delivering, or you have recently redesigned and traffic dropped, a professional audit will usually save you time and money by pointing effort at what matters.
