Audit your website

Audit your website


Technical SEO errors can hold back your site and negatively impact rankings, overall visibility, and conversions. To identify and fix such issues quickly, use the Semrush Site Audit Tool. It crawls a domain and creates a report to show where there are potential problems and suggests recommendations on how to improve your website’s technical health. Site Audit offers a range of thematic reports covering crawlability, HTTPS, site performance, Core Web Vitals and more.

We’ve put together this workflow to show how you can organize your work in Site Audit in an efficient way. Follow these steps to quickly discover a website’s gaps you need to focus on first to improve its technical health and as a result enhance its visibility.

1. Launch Site Audit 

If you haven’t set up any project in Semrush yet, you will see the following screen when clicking on Site Audit. To start, enter a domain that you would like to scan for technical issues and click on Start Audit. The next step is to configure your audit campaign.

In case you’ve already created a project on the platform, navigate to Site Audit to Set up the tool under an existing project (2) or create a new one with the Add new project button in the upper right corner (1).

To start, you can run an audit with default settings. 

You will only need to select how many pages you want to crawl per audit. By default the tool will check 100 pages but if your site has more pages, use the drop-down menu or the custom option to specify the number. If you’re using a free account without an active trial, you can crawl 100 pages per month. Free trials give you temporary access to either Pro or Guru subscriptions that allow you to crawl 100 000 and 300 000 pages per month respectively.

Click Start Audit and wait for the tool to scan your website’s pages. The time of crawling varies depending on your crawl-delay setting and the size of your audit.

If necessary, you can customize the crawl by using the configuration options. Below we will cover a few basic customization settings that will help you adjust an audit to your needs.

Auditing Subdomains and Subfolders

By default the tool checks the root domain, which includes all available subdomains and subfolders of your site. In Site Audit settings, you can specify your subdomain or subfolder like a crawl scope and untick ‘Crawl all subdomains’, if you don’t want other subdomains to be crawled. 

For example, you want to audit only the blog of your website. You can specify the crawl scope as blog.semrush.com or semrush.com/blog/ depending on whether it’s implemented as a subdomain or a subfolder.

Auditing Mobile Version of a Website

By default we check your site with our mobile crawling bot that helps to audit your website in the same way Google’s mobile crawler would go through your website. You can change the bot to Semrush desktop crawler anytime.

If the mobile version is located on a separate subdomain (m.example.com), use the crawl scope field to audit only that subdomain.

2. Prioritize Your Work

Once you’ve set up your audit campaign, you can start working through the issues identified by the tool. A technical SEO audit isn’t easy. The first time you face an audit, it can seem like there’s just too much to do. Let's see how you can organize your work in Site Audit to quickly improve your site’s health and visibility.

Errors / Warnings / Notices

When Semrush finishes auditing your website, you get a Site Health score representing how healthy the website is. The Site Health Score is based on the number of your total errors and total warnings that were found on the pages crawled on your site. 

Errors are the most important problems on the website that need attention first. Errors have more weight on your Health Score compared to warnings and notices.

So, the best way to start making changes on your site that will significantly improve its health and visibility would be to work on all of the Errors. Next, move to Warnings and Notices to improve your website’s health further.

Use the Site Audit tooltips “why and how to fix it” to learn more about each issue and how to resolve it.

Top Issues

The second way to prioritize your work is to fix what’s in your list of Top Issues. You will find the liston the Overview tab under the Thematic Reports. Top Issues are the most important issues detected on your website based on their repetition and priority level. For quick wins, you can start working on this list first.

Connect Google Analytics

Another way to achieve a quick win is to connect your Google Analytics Account to see the pages with a higher number of visits and fix their problems first, so you do not lose this important traffic.

More Filters 

To work through the Crawled pages report, you can apply various filters. For example, if you first want to deal with pages that respond with 4xx and 5xx status codes to quickly improve your site’s crawlability.

You can combine multiple filters at once to get the exact results you need. 

Category Filter

The Category filter can also be your lifesaver if you want to tackle a particular group of issues first. You can find the filter in the Issues report. For example, you can start by fixing crawlability issues first because even small crawlability problems could result in your site losing rankings.

Pro tip: You can use our Log File Analyzer tool, which analyzes your access logs and presents a report about how GoogleBot crawled your website, and if there are any errors to fix and crawl budget to save. All you have to do is upload the access log file of your website, and let the tool do its job.

Thematic Reports

Thematic reports on the Overview tab dive into specific aspects of a website where common issues are found. This is where you can quickly assess if you have any issues related to a website’s transition from HTTP to HTTPS, hreflang and structured data implementation, crawlability, Internal linking between pages or Site performance.Audit your website image 14

Core Web Vitals is our latest addition to the Thematic reports. It contains a set of metrics that measure the loading performance, interactivity, and visual stability of a website. These metrics are confirmed to be a ranking factor by Google, so fixing those issues can be a great way to improve your pages’ positions on SERP.

We have covered a few ways of grouping and prioritizing issues which can help you adjust the workflow to your needs. The next step would be to share the tasks with your team or webmaster. 

3. Send Issues to Task Trackers

Stay organized and keep your team updated on the technical audit. The more you work together to keep your website running smoothly, the better your technical SEO audits will go.

If your team is using a task tracker like Trello, you can send issues directly to your team’s board by integrating Semrush with this tool. Other task managers like Asana, Monday, or Jira can be connected to Site Audit via Zapier (online automation tool that connects various apps). Learn more about this integration in the manual How To Integrate Site Audit with Zapier.

Another option here is to send a task to the Client Manager (CRM). This is a management service inside Semrush that allows you to easily streamline your customer management workflows all in one place.

In case you are not using any task managers, you can simply export the list of pages with the issue and send the file to your webmaster.

4. Track Changes in the Progress Tab

After fixing the critical issues on your site, you can re-run your campaign to check how the changes affected your website’s Health Score.

The Progress report is the best way to measure the success of your efforts.

This report features an interactive line graph that lets you visualize how the number of issues or other metrics have changed over time with your audits.

Schedule Site Audit on a regular basis, so you’ll be able to timely notice all important issues that should be fixed.

5. Monitor Visibility Progress in Position Tracker  

You see that your Site Health Score has improved, but is there a way to check the effects of your work on the website’s visibility?

Yes, there is! You can track how the changes affect the rankings of your website’s pages with our Position tracking tool. Set up a tracking campaign and add a note each time you fixed or optimized something on your website.
