What Are the Best SEO Audit Tools?

The SEO audit tool you choose depends on your needs. But here are five of the best SEO audit tools we recommend (that cover most areas):

What to Look for in SEO Audit Tools

SEO audit tools have a lot of different features. Here are the top functions to add to your shopping list:

• Comprehensive crawling: The ability to thoroughly crawl your entire website, including all pages, links, and images to identify technical errors. To get this, make sure the plan you choose has a crawl limit that exceeds the number of pages on your website.
• Technical SEO analysis: Identification and prioritization of technical issues like broken links, duplicate content, missing meta tags, and page speed problems
• Actionable recommendations: Clear guidance on which issues to address in order to improve SEO performance. Ideally, with prioritization and basic instructions.
• Backlink analysis: Insights into your backlink profile, including the number of links you have and the quality of each
• Reporting and visualization: Clear and concise reports that highlight key issues
• Integration with other tools: The ability to connect with other SEO tools like Google Search Console and Google Analytics

With these qualities in mind, let’s look at why each tool made our final list.

1. Semrush’s Site Audit

Best for identifying technical SEO issues on the site.

Semrush’s Site Audit tool lets you identify and fix over 140 potential technical SEO issues. Use this tool to:

Check Every Page on Your Website

In your Semrush dashboard, locate the “ON PAGE & TECH SEO” section in the left-side menu. Then click on “Site Audit.”

Enter your domain and click “Start Audit.”

The tool will analyze your site and generate a series of reports. Like this:

This tool provides an overall assessment of your site’s health. And breaks the data down into seven “Thematic Reports.”

They include:

• Crawlability: How easily search engines can access and index your site’s content
• HTTPS: Whether your site uses a secure connection (HTTPS) to protect user data
• International SEO: How well your site is optimized for different languages and regions
• Core Web Vitals (CWV): Key user experience metrics that measure your site’s loading performance, interactivity, and visual stability
• Site Performance: Overall speed and responsiveness of your site
• Internal Linking: How well your pages are linked together to facilitate user navigation and help search engines understand your content
• Markup: The degree to which you’ve used structured data to provide additional information to search engines about your content

Click the “View details” button in each report to see a detailed analysis related to that aspect.

For example: Clicking “View details” for the “Crawlability” report will show you how many pages on your website are indexable vs non-indexable.

Get a Prioritized List of Issues and Recommendations

Return to the main report page by clicking the “Overview” tab. Then click the number in the “Errors” report.

This will take you to a list of all the errors Semrush found on your website.

Click the “Why and how to fix it” link next to the error you’d like to learn more about. You’ll get detailed information about why you should fix the specific issue and how to do it.

Then, follow Semrush’s recommendations and fix the issues one by one to improve your SEO.

Share the List of Issues

If you’d like to share the list of detected issues, like with an SEO team or a client, click the “Export” button in the top-right corner of the page. Then click “Export to XLSX” or “Export to CSV” depending on the file format you prefer.

Send the file via email or messenger of your choice.

Schedule an SEO Analysis

From the site audit page, click “Settings” (gear icon in the upper right). Then, click “Crawl sources: Website” (or any other option under the “Site Audit settings” section).

Optionally, you can configure your site audit by adjusting crawler settings, allowing/disallowing URLs, removing URL parameters, or bypassing website restrictions on the various tabs of the “Site Audit settings” menu.

Once your audit is set up the way you’d like, click the “Schedule” tab in the purple navigation menu. Use the drop-down menu to select your audit frequency. Tick the checkbox if you want to receive reports via email. And finally, click “Save.”

Identify SEO Issues

To start auditing a website, navigate to “Audit” > “All reports” from the left-side menu.

Click the “+ NEW AUDIT” button. Enter the domain and name your audit. Choose where to save it and, if you like, provide instructions about which pages to audit. When settings are complete, click “RUN AUDIT.”

Once SE Ranking crawls all the pages (which can take up to 10 minutes), it provides an illustrated overview.

Here, you’ll see the website’s health score, Core Web Vitals overview, and issues.

Click “VIEW ALL” in the “Top Issues” section to review crucial issues on the website.

The tool sorts issues by category (like website security and duplicate content). And importance (like errors, warnings, and notices).

Let’s say you want to investigate important issues. Click the issue group (like “HTTP Status Code”) and click one of the issues marked with the red icon (like “4XX HTTP Status Codes”).

Read the issue description to understand its importance. Then move on to the “How to fix” section for actionable tips to solve the issue.

Sort Individual Audits into Groups

One of the standout features SE Ranking’s Website Audit tool offers is its ability to group web assets.

Navigate to “Website Audit” from the left-side menu and click the “+ NEW AUDIT” button in the upper right.

Insert your client’s domain. Then, name your audit and use the drop-down to create a new group for it.

For example, you could create a group “Local Businesses” to help sort your clients based on their business type.

When you’re all set, click the “RUN AUDIT” button.

Now, you have two groups. One general purpose, and one for whichever category you just created.

Build White Label Reports

Click “Report Builder” in the left side menu. Then click the “CREATE REPORT” button in the upper right.

Select your project and the date range of the audit. Choose a desired export format (like PDF, XLS, or HTML).

Optionally, schedule your report to be generated daily, weekly, or monthly.

Next, click the “Formatting” section to create a layout for your report.

4. Conductor Website Monitoring, Powered by ContentKing

Best for getting customized, real-time alerts of website changes and issues.

Conductor is an enterprise SEO platform. It helps you find technical issues, track keyword rankings, and improve your content strategy. Understand your competitors and monitor your SEO progress with custom reports.

Pros and Cons

Price

Conductor offers custom pricing based on the number of total web pages you need to audit. You can distribute the number of pages across multiple websites.

5. Google Search Console

Best for monitoring your site’s presence in Google Search.

Google Search Console (GSC) helps you monitor your website’s presence in Google search results.

With GSC, you can:

• Identify technical issues
• Submit sitemaps
• Request indexing of new or updated pages

Google Search Console is a must-have tool for any website.

However, for a comprehensive SEO audit, we recommend you pair it with more advanced tools like Semrush.

While GSC provides insights into your site’s performance on Google, it lacks certain functionalities. Like prioritized lists of SEO issues. And actionable suggestions to fix them. Or backlink analysis.

But it’s absolutely worth using the following functions:

Make Sure Your Pages Are Indexed

In Google Search Console, click “Pages” under the “Indexing” section of the side navigation menu.

For example, it tells us that 21.3K of our pages are indexed. And 495 are not.

Scroll down the page to view the breakdown of non-indexed pages. And see why they’re not indexed.

Then, click one of the reasons to see how many and which pages are affected. Like this:

From here, investigate each page by clicking on its URL, which will take you directly to the page on your website.

Determine if you should redirect, restore, or remove the page based on the reason it was flagged and its current content.

Check Your Website Performance

Navigate to the “Performance” and click on “Search results” report.

Here, you can see your website’s:

• Total clicks
• Total impressions
• Average click-through rate (CTR)
• Average position

Use filters (which you can find on top of the performance chart) to refine your search performance data by:

• Search type (web, image, video, news)
• Date
• Query (keyword included in search)
• Page (insert a specific URL)
• Country
• Device (desktop, mobile, tablet)

Share Your Performance

To share your SEO performance with your clients or team members, click “Export.” And select the file type of your choice.

Pros and Cons

Price

Google Search Console is free.
