You can do an SEO audit yourself, but a useful audit takes substantially more than running your website through a tool or asking ChatGPT what is wrong. You need to understand what search should accomplish for the business, pull information from several sources, figure out which findings are significant, decide what deserves your attention first, and actually do the work to improve your web presence.
In this guide, we’ll walk through the major areas to review, the free and paid tools that can help, how ChatGPT fits into the process, and how to turn everything you find into a practical SEO roadmap. We’ll also cover how often to revisit your site, what an SEO audit can cost, and when bringing in professional help may be a better use of your time.
What Is an SEO Audit?
An SEO audit is a structured evaluation of your website to understand what is helping or hurting its visibility in search and where there are opportunities to improve. A good audit examines how search engines access and understand your site, whether your content matches what people are searching for, how your pages are organized and connected, how your authority compares with competitors, and whether your SEO efforts are actually contributing to business goals.
Depending on the purpose of the audit, that can mean digging into technical issues, content performance, keywords, internal linking, backlinks, analytics, competitors, or visibility in newer AI-driven search experiences, but usually some combination of the above.
Most importantly, an SEO audit should determine which findings are actually important, why they are meaningful, and what should be done about them. A site can have hundreds of warnings in an SEO tool without all of them deserving your time or resources.
Can You Do Your Own SEO Audit?
Yes. You can absolutely do your own SEO audit if you have the time, interest, tools, and patience to collect the right data, understand what it is telling you, decide what actually needs to change, and make sure those changes get implemented.
It’s a little like working on your own car. You can learn how to change the oil, diagnose a strange noise, replace a part, or even tackle a much bigger repair. There are tutorials, tools, forums, and increasingly AI assistants that can help you figure out what to do. For some people, going this route is genuinely useful and even fun. But many others would way rather take their car to the mechanic than deal with everything themselves.
An SEO audit is similar. You may need to pull information from Google Search Console, GA4, crawling software, keyword tools, backlink data, competitors, search results, AI platforms, and the website itself. Then you have to connect those data points and determine which findings are worthy of attention, which ones aren’t worth your time, what should happen first, and what resources will be required to fix them.
And the audit is only the beginning. Someone still has to implement the recommendations, check whether they worked, keep an eye out for new issues, and continue looking for opportunities as the website, competitors, search results, and the business itself change.
So yes, DIY SEO audits are possible. But the real question is whether or not DIYing an audit is the best use of your time and skill set.
How to Do an SEO Audit Step by Step
There isn’t one exact SEO audit checklist that makes sense for every website. A small local business, a SaaS company with thousands of indexed pages, and an e-commerce site recovering from a migration are going to require very different levels and flavors of investigation. That said, most SEO audits work through the following areas:
1. Understand What the Business Actually Needs From Search
We call this first step a “use your brain task.”
Before opening Search Console, running a crawl, or looking at keyword data, you need to understand what the business actually needs search to accomplish. The answer can look very different from one company to the next. Maybe you need organic search to help carry the business through slower winter months when in-person sales drop off. Maybe you’re getting plenty of traffic, but most of it is coming from teenagers who aren’t going to spend any money because they’re actually looking for something slightly different than what you offer. Or maybe the goal is less transactional. Perhaps you need the right people to find you, understand what you stand for, trust your expertise and vision, and eventually want to invest in your company or work with you.
Chances are, you already understand what you need. But we don’t take it for granted that everyone has this kind of clarity. If you aren’t sure, that’s useful information too. It may mean the first step isn’t auditing your website at all, but getting clearer on who you need to reach, what you want them to do, and what a meaningful result from search would actually look like. Sometimes that’s something you can work through internally, and sometimes an outside perspective can help you ask the right questions.
2. Crawl the Website and Check Technical Health
Next, crawl the website to understand how it is structured and identify technical issues that could be getting in the way of search performance. Tools like Screaming Frog can surface broken links, redirect chains, duplicate or missing metadata, canonical issues, indexability problems, unusually deep pages, and other patterns that are difficult to spot by clicking around the site manually.
H3: 3. Compare the Crawl With Google Search Console
From there, check Google Search Console to see how Google is actually indexing the site, review XML sitemaps and robots.txt files, and investigate things like page speed, Core Web Vitals, mobile usability, structured data, and rendering when they are relevant to the site.
4. Analyze Organic Traffic and Conversions
Next, look at what happens after people actually reach the site. GA4 or another analytics platform can help you understand which organic landing pages attract visitors, how that traffic changes over time, and whether those visitors are taking the actions you actually care about.
Note which pages are bringing in qualified visitors, which are contributing to leads, purchases, demo requests, calls, sign-ups, or other meaningful conversions, and where performance has improved or declined. A page with fewer visits can be far more valuable than one generating thousands of sessions if it is reaching the right audience and driving business.
This is also a good time to look for patterns. Did organic traffic fall across the entire site or only within one section? Is a decline actually abnormal, or does the business experience the same seasonal dip every year? Are conversions dropping because traffic quality changed, or because something on the site changed after visitors arrived?
And before drawing conclusions, make sure the tracking itself is trustworthy. If forms, calls, purchases, or other important actions are not being measured correctly, you may be trying to diagnose SEO performance using incomplete information.
5. Review Keywords, Search Intent, and Ranking Pages
Now look at the searches bringing people to the site and ask whether they line up with what the business actually wants to be found for.
Start with the queries and pages already getting impressions and clicks in Google Search Console, then layer in keyword research to understand what else people are searching for, how much demand exists, and where the site may be missing opportunities. Look for important terms where you have no strong page, pages ranking just outside the top results, multiple URLs competing for similar searches, or pages attracting traffic for queries that do not actually fit the business.
Search the terms you care about and look at what Google is actually showing. Are people looking for a service page, a comparison, a how-to guide, a product, a local business, or a quick answer? A page can be well written and technically optimized and still struggle if it is answering a different question than the searcher is asking.
Look at which websites and pages consistently appear for the searches that you care about, what they are doing well, and where there may be gaps you can realistically fill. Consider, too, how your brand and its competitors are appearing in AI search experiences to understand whether the same topics, sources, and entities are showing up there.
6. Audit Existing Content
Next, look closely at the content already on the site and decide what deserves to stay, what could perform better, and what may no longer be helping.
Depending on the size and history of the website, this can be a quick review or a very granular page-by-page exercise. Look at which pages are getting traffic, ranking for valuable searches, earning links, contributing to conversions, or supporting other important pages. Just as importantly, identify content that overlaps with other pages, targets the wrong intent, has become outdated, attracts the wrong audience, or no longer has a clear purpose.
Strong content may only need better targeting, internal links, or a few updates. Two similar pages might make more sense consolidated into one stronger resource. A useful page may need to be repositioned around a different keyword. And content that is outdated, redundant, or fundamentally misaligned may be better redirected or removed.
Be especially careful with content that is already working. An SEO audit should not create change for the sake of change. Sometimes the smartest recommendation is to leave a great page alone and focus your energy somewhere else.
7. Review Site Architecture and Internal Links
Next, look at how the website is organized and how easily both people and search engines can move through it. Important pages should be easy to find, clearly connected to related content, and positioned within a site structure that reflects what the business actually wants to be known for.
Review the main navigation, category, and subcategory structure, click depth, orphaned pages, and internal links throughout the site. Look for valuable pages that receive very few internal links, supporting content that never points readers toward a relevant service or product page, or important sections of the site that feel disconnected from everything around them.
Pay attention to the links themselves, too. Descriptive anchor text can help search engines understand how pages relate to one another while also giving users a clearer idea of where they are going next. Internal links should feel useful and natural, not like keywords were forced into every paragraph for the sake of SEO.
8. Compare the Site With Search Competitors
Next, zoom out and look at the websites consistently competing with you in search. These may not be the companies your sales team considers direct competitors. A publisher, marketplace, association, review site, or much larger brand may be competing for the same visibility even if they would never come up in a traditional competitive analysis.
Compare the sites more broadly. What topics do they cover that you don’t? Do they have stronger service or product pages, deeper supporting content, clearer site architecture, or resources that consistently earn visibility? Are they answering questions your audience is asking that your site never addresses? Just as importantly, look for places where competitors are weak, and your business has something genuinely different or more useful to offer.
9. Review Backlinks and Authority
Next, look at the websites linking to you and what those links suggest about your authority relative to the competitors you care about.
Don’t get too distracted by the total number of backlinks. One sitewide link can create thousands of links from a single domain, while one relevant mention from a respected industry publication may be far more meaningful. Look more closely at referring domains, the relevance and quality of those sources, which pages are attracting links, and whether competitors have earned authority from places you have not.
Keep an eye out for what is already working. Maybe original research is consistently earning links. Maybe your strongest mentions come from industry organizations, local publications, partners, or digital PR. The patterns you notice can help point toward the kinds of authority-building efforts that are most likely to make sense going forward.
Also, keep on the lookout for anything unusual, such as a sudden influx of low-quality links or backlink patterns that do not make sense for the business. More backlinks is not automatically better. You need credible, relevant sources to give search engines and potential customers additional reasons to trust your site.
10. Turn Everything Into a Prioritized SEO Roadmap
At this point, you may have a very long list of technical issues, content opportunities, keyword gaps, competitive weaknesses, and pages that need attention. Now you get to decide what actually deserves to happen first.
Not every issue is equally important. A broken internal link on an old blog post is not the same as an indexing problem affecting your highest-value service pages. A keyword opportunity with huge search volume may matter less than a smaller one that closely aligns with what the business sells. And some recommendations may be worthwhile eventually, but not worth pulling time or development resources away from more important work right now.
Prioritize findings based on things like potential impact, business importance, level of effort, urgency, and whether one task needs to happen before another can realistically move forward. Your roadmap should make it clear what needs immediate attention, what belongs in the next phase of work, and what can safely wait.
Make sure your roadmap connects back to the goals you identified at the beginning of the audit so that you efficiently fix things that actually move the business forward.
What Can a Free SEO Audit Tool Actually Tell You?
A free SEO audit tool can be useful, but it’s important to understand what you’re actually getting. We use tools constantly in our own SEO work, though most of the platforms required for a comprehensive audit are paid.
There are a few very important exceptions. Google Search Console is free and provides direct insight into how a site is performing in Google, including which queries and pages are earning impressions and clicks, indexing issues, and other search data. Microsoft Clarity is also free and helps us understand what people actually do once they reach the site through tools like heatmaps and session recordings.
We also use Screaming Frog to crawl websites and uncover technical patterns across hundreds or thousands of URLs. The free version can crawl up to 500 URLs at once, so this may be an option depending on the size of your site.
In terms of other free tools, we use smaller browser extensions like Link Redirect Trace to quickly understand redirects and HTTP headers, and SEO Meta in 1 Click when we want a fast look at a page’s titles, descriptions, headings, canonicals, and other on-page elements.
We’ve also built our own collection of free Cadence SEARCH Tools. These exist largely because we needed them ourselves. In some cases, the tool we wanted didn’t exist; in others, we couldn’t find one that worked quite the way we needed it to. So we built our own versions and made them available for anyone else who might find them useful, too.
Can ChatGPT Do an SEO Audit?
Yes, ChatGPT can help you do an SEO audit. But the quality of the audit depends heavily on what you give it and how you engage with the LLM.
If you simply provide your URL and ask ChatGPT to “audit my website,” it can search the public web, review accessible pages, and offer observations. But that is very different from giving it a Screaming Frog crawl, Google Search Console, and GA4 exports, keyword research, backlink data, competitor information, and context about what the business is actually trying to accomplish.
ChatGPT can analyze uploaded spreadsheets and other structured data, making it genuinely useful for identifying patterns across large SEO datasets. Give it the right inputs, and it can help you identify pages that lost clicks, group thousands of keywords, compare time periods, find possible cannibalization, categorize technical errors, spot content gaps, or surface patterns that would otherwise take a long time to work through manually.
We use AI for these types of tasks with large computational lifts. What we don’t do is assume that the first conclusion it reaches is necessarily the right one. ChatGPT can be (and often is) confidently wrong. It may also be unable to access everything on a website because of technical restrictions, robots.txt rules, or other limitations.
How Often Should You Do an SEO Audit?
A full audit may make sense when your goals change, you’re preparing for a major website redesign or migration, performance shifts in a meaningful way, the site has changed substantially since the last review, or enough time has passed that you need to reassess your priorities. Between those larger reviews, ongoing site checks can help you understand what is changing and whether the work you’ve already done is having the intended effect.
SEO also takes time. Changes you make today may take weeks or months to produce a meaningful result, and search performance naturally fluctuates along the way. Reacting to every ranking movement or week-over-week traffic dip can lead you to make changes before you have enough information to know whether anything is actually wrong.
We look for trends over meaningful periods of time. For example, comparing the most recent 30 days to the same period last year can help account for seasonality and provide more context than reacting to a short-term change.
How Much Does an SEO Audit Cost?
There isn’t a standard price for an SEO audit because there isn’t a standard amount of work involved. The cost depends on the size and complexity of the website, what you are trying to figure out, how much data needs to be reviewed, and how deeply someone needs to investigate the issues they find.
You can also find plenty of free SEO audits online. Some are automated tools that crawl a website, run a predetermined set of checks, and generate a report. Those can be useful for identifying potential problems, especially if you are doing an audit yourself, but they are different from having someone investigate the site and interpret the findings.
Free doesn’t necessarily have to mean automated, though.
At Cadence, we offer a free SEO strategy session that includes many of the elements we would look at during an audit. A real person reviews your website, pulls available search and competitive data, looks for meaningful problems and opportunities, and puts those findings together before talking through them with you.
There are limits to what we can evaluate during a free strategy session. We typically don’t have access to private information like your Google Search Console or analytics data, and we aren’t conducting every step of a full SEO audit. But you can still learn quite a bit from an experienced person looking at your website, the public data around it, and how everything fits together.
When a company signs on with Cadence, a deeper audit is generally the first step in the scope of work. It gives us the information we need to understand where things stand, identify what deserves attention, and build the roadmap for what we are actually going to work on together.
We don’t require a lengthy commitment to do a comprehensive SEO audit and get the work underway. Our plans are structured as month-to-month engagements and offered in tiers tailored to businesses of various sizes and growth strategies.
When Should You Hire Professional SEO Audit Services?
You should consider hiring professional SEO help when search is important enough to your business to warrant dedicated expertise, but building or maintaining that expertise in-house doesn’t make sense.
Going back to our mechanic comparison, most people wouldn’t take their car to a mechanic, pay them to diagnose everything that’s wrong, collect a detailed list of repairs, and then drive away without fixing anything. You want the mechanic to diagnose the problem and help you fix it.
We look at SEO audits much the same way. There is certainly value in having someone review your website and share their findings, especially if you have an internal team capable of implementing the recommendations. But for many businesses, the audit is most useful as the starting point rather than the finished product.
What Does a Cadence SEARCH Audit Look Like?
A Cadence SEARCH audit starts before you ever become a client and gets considerably deeper if we end up working together. Our free strategy session gives you an initial human assessment of your search opportunities, while the full audit at the beginning of an engagement combines keyword research, technical and content analysis, and business context into the strategy we’ll actually execute.
At a minimum, four people are usually involved in a full Cadence audit. The team typically includes the account manager, SEO strategist, content director, and additional experts with specialized experience. We bring all of our expertise and findings together to build the strategy and roadmap we will work from in partnership with you.
Not Sure What Your Site Needs? Let’s Take a Look.
You can learn a lot about your website with the right tools, and we hope this guide helps you do exactly that. But if you’ve got crawl reports, Search Console exports, ChatGPT recommendations, and a growing list of SEO issues without knowing what is actually relevant and what to do next, that’s where we can help.
