By the end of this guide you will have crawled your website, produced a ranked list of technical SEO problems, fixed the ones that matter most, and re-run the audit to confirm they are gone. An AI SEO audit tool does the crawling and checking, then explains each issue and often drafts the fix. You decide what is worth doing and make sure the changes are safe.
If you want to run a technical SEO audit with AI, the real choice is between a standalone auditor, a broader SEO platform that includes audits, and a command-line crawler that fits a developer workflow. This guide compares six tools from our Marketing and SEO category and walks through the process from first crawl to follow-up.
Key takeaways
- Crawl the site, sort the findings by impact, fix critical issues first (crawl errors, broken links, speed, metadata), then re-audit to verify.
- The main decision is tool type: a focused auditor, an SEO platform with automation, or a command-line crawler you can hand to a coding agent.
- Free plans cap crawl size, for example 10 pages on AuditZap's Free plan, so a free audit may cover only part of your site.
- AI impact scores and fix instructions are estimates. Review every change before you apply it, and take a backup first.
What you need before you start
- Your site's address and access. Admin access to the CMS, or a developer who can make changes.
- Search data. Access to Google Search Console if you want the tool to use it. Search Atlas and Pixis both list that integration.
- A list of priority pages. Home page, top landing pages, product or service pages.
- A way to roll back. A backup or version history, so you can undo a change that breaks something.
- Time. A first audit and triage takes under an hour for a small site. Fixes take longer.
- Difficulty. Easy for web-based auditors, moderate when fixes touch code, and technical for command-line tools.
- Permission. Only crawl sites you own or manage, or have written permission to audit.
Which kind of AI tool fits this job
Pick by site size, who will do the fixes and how often you will re-audit.
Focused audit tools. AuditZap crawls a URL, scores 40 checks and returns a report where each issue carries an estimated revenue impact. An AI step writes a plain-English fix for your CMS, such as WordPress, Shopify, Webflow, Squarespace, Next.js, Wix or Ghost. It also has nine checks for AI search visibility. squirrelscan is a command-line auditor that reports on SEO, performance, security, accessibility and agent experience, with exact fixes you can pass to a coding agent. Local audits are free and unlimited when signed out or offline.
SEO platforms with audits and automation. Search Atlas combines keyword tracking, site audits, content tools and OTTO SEO automation for on-site optimization, and can publish to WordPress, Shopify, Webflow and other CMSs. Pixis has a Visibility product that includes a technical SEO audit covering Core Web Vitals, crawl errors and sitemaps, alongside keyword tracking and tracking of how your brand appears in AI answers.
Marketing dashboards that include SEO audits. Adzooma brings paid ads, SEO and website performance into one dashboard. Its SEO audits cover keywords, on-page factors, page speed and backlinks, and there is a separate website speed audit. Frase is a content platform with site audits as one of its features, plus a content-monitoring tool that watches live pages for ranking decay.
Step 1: Define the scope of the audit
An audit is easier to act on when you know what you are checking and why.
- Write the goal: fix indexing problems, improve speed, prepare for a redesign, or a routine health check.
- List the sections of the site in scope, and the ones to ignore, such as staging areas.
- Decide who will make the fixes and what they can change.
- Note any recent changes, such as a migration or a new theme, which often cause problems.
Check it worked by being able to say in one sentence what a successful audit looks like.
Step 2: Pick a tool and check its crawl limits
You end this step with one tool and a plan that can cover your site.
- Count your pages roughly, using your sitemap or CMS.
- Check crawl limits. AuditZap crawls up to 10 pages on Free, 100 on Pro and 250 on Agency. squirrelscan's free cloud audits crawl at most 500 pages.
- Check how usage is metered. squirrelscan cloud audits use credits, at 50 credits per audit plus 2 per audited page, while Search Atlas draws on one monthly pool of Universal Credits.
- Look for trials. Search Atlas offers a 7-day trial with free 1-on-1 onboarding, and Frase begins every plan with a free 7-day trial.
- Use the comparison table below to weigh pricing and stated limits.
Check it worked by confirming the tool's page limit is at least the size of the section you want to audit.
Step 3: Connect your data and run the crawl
Start the crawl from the home page, and add search data if the tool supports it.
- Enter your URL, or run the command-line audit against your site.
- Connect Google Search Console if offered. It gives the tool real search data to work with.
- Run the audit and wait for it to finish. Heavily scripted sites may need rendering: squirrelscan can render JavaScript-heavy sites in a headless browser when you are signed in.
- Save or export the first report so you have a baseline.
Check it worked by seeing a list of issues with the number of pages crawled.
Step 4: Triage the findings
Not every flagged item matters, so sort before you fix.
- Group issues: indexing and crawl errors, broken links, speed and Core Web Vitals, metadata, security, accessibility.
- Start with anything that stops pages being found or loaded: crawl errors, broken links, missing or wrong sitemaps.
- Use the impact ranking if the tool gives one. AuditZap ranks issues by AI-estimated impact.
- Treat estimates with care. AuditZap states that impact scores and fix instructions are AI estimates to review before applying.
- Make a short list of fixes you will do this week.
Check it worked by having a short, ordered to-do list with an owner for each item.
Step 5: Fix the issues
Work through the list in small batches so you can tell what changed what.
- Back up the site or make sure you can roll back.
- Apply the fix using the tool's instructions. AuditZap writes steps for your CMS, and squirrelscan produces fixes you can pass to a coding agent.
- If you use automation, understand what it changes. Search Atlas offers OTTO SEO for on-site optimization, so review its changes before and after.
- Repair broken links, add missing metadata, resolve crawl errors and compress or lazy-load heavy assets.
- Test key pages by hand after each batch.
Check it worked by visiting several fixed pages and confirming they load and display correctly.
Step 6: Re-audit and verify
A fix is only proven when the tool no longer reports the problem.
- Run the audit again. AuditZap supports re-audit comparison and a click-to-verify check that a fix worked.
- Compare the new report with your baseline.
- If an issue remains, check whether the fix was deployed, cached or applied to the wrong page.
- Record what changed and the date.
Check it worked by seeing the fixed issues gone from the new report and no new ones introduced.
Step 7: Schedule recurring audits
Sites change constantly, so make the check routine.
- Set up scheduled audits where offered. squirrelscan schedules audits weekly on Free and daily on paid plans, and AuditZap sends weekly monitoring emails for up to 5 sites on Pro.
- Choose who receives reports.
- Set a review date each month to look at trends.
- Re-audit after every major change, such as a redesign, migration or plugin update.
Check it worked by receiving the first scheduled report and finding it in your inbox or dashboard.

Common mistakes to avoid
- Auditing only a sample and calling it done. Free plans crawl a limited number of pages, so the report may miss problems elsewhere. Fix it by checking the crawl limit and auditing the sections that matter in turn.
- Applying every fix blindly. AI instructions are estimates and can be wrong for your setup. Fix it by reviewing each change, working in batches and keeping a rollback.
- Chasing a perfect score. A high score does not guarantee better rankings, and low-impact items can eat your time. Fix it by working from the impact ranking and your goal.
- Skipping the re-audit. Without it, you cannot tell whether a change worked or broke something else. Fix it by running the audit again after each batch.
- Auditing sites you do not control. Crawling or changing a site without permission can cause problems. Fix it by getting written agreement before you audit a client's or third party's site.

Frequently asked questions
Is there a free way to run a technical SEO audit with AI?
Yes, with limits. AuditZap's Free plan gives 3 audits per rolling 30 days with a 10-page crawl, squirrelscan runs unlimited local audits when signed out or offline, and Adzooma has a free plan with 1 user seat and 1 SEO profile. Larger sites will need a paid plan.
Can AI find every SEO problem on my site?
No. A crawl covers only the pages it reaches, and AuditZap notes that results may not represent the whole site. Use the report as a strong starting point, then check priority pages by hand and watch your search data.
How long does an audit take?
The tools do not publish standard run times. A small site can be audited and triaged in under an hour, while fixing issues depends on how many there are and who can make the changes.
Which tool is good for developers?
squirrelscan is a command-line auditor with a REST API and MCP server, and it produces fixes you can pass to a coding agent. Check its listing for current credit and plan details.
Do I need to know how to code?
Not for the web-based tools. AuditZap writes fix instructions for common CMSs, and Search Atlas offers automation for on-site optimization. Some fixes, such as server settings or code changes, may still need a developer.
