How do I use the SEMrush website checker? 6 Simple steps

Checking your website’s SEO health is one of the fastest ways to identify what’s holding your rankings back. And instead of guessing, tools like SEMrush can provide users with a structured way to diagnose issues and improve performance, which leads to the question: How do I use the SEMrush website checker? In this quick guide, MKT Software will explain what the SEMrush website checker is and how to use it step by step.

What is SEMrush?

SEMrush is an all-in-one SEO and digital marketing platform used to analyze websites, research keywords, monitor rankings, and evaluate competitors. What makes SEMrush particularly valuable is its ability to connect multiple SEO tasks into one workflow. Rather than using separate tools for audits, keyword research, and tracking, you can manage everything within a single interface. This is especially useful for beginners who need a clear and structured starting point.

What is SEMrush website checker?

The SEMrush website checker typically refers to the Site Audit tool, which evaluates the technical health of your website. This tool works by crawling your site in a way similar to search engine bots and identifying issues that may affect your visibility in search results. It provides insights into areas such as:

• Crawlability and indexability.
• Broken links and redirects.
• Duplicate content.
• Page speed and performance.
• Internal linking structure.

The results are summarized into a Site Health score, giving you a quick overview of how well your website is optimized from a technical perspective. Want to know more about SEMrush features? Read: A Strategic 2026 Guide to Using SEMrush Features 

How do I use the SEMrush website checker?

Using the website checker in SEMrush is a structured process that helps you evaluate and improve your website’s technical SEO. While the tool itself is easy to access, following the steps in the correct order ensures that the insights you receive are both accurate and actionable.

Step 1: Create a project and access Site Audit

Start by logging into SEMrush and navigating to the Projects section. Enter your domain to create a new project, then select the Site Audit tool. At this stage, you can also connect tools like Google Search Console to enhance data accuracy. Setting up your project correctly ensures that all future audits are consistent and reliable.

Step 2: Configure crawl settings

Before running the audit, define how SEMrush should crawl your website. This includes setting:

• The number of pages to scan.
• The crawl source (entire site, sitemap, or specific URLs).
• Device type (desktop or mobile).

These settings determine the scope of your audit, so it is important to configure them based on your website size and structure.

Step 3: Run the website audit

Once everything is configured, start the audit. SEMrush will crawl your website similarly to a search engine, analyzing technical elements such as page structure, links, and performance. The process may take a few minutes depending on the number of pages being analyzed.

Step 4: Review the Site Health score and issue categories

After the audit is complete, SEMrush provides a Site Health score along with a breakdown of issues into:

• Errors (critical issues)
• Warnings (moderate issues)
• Notices (minor improvements)

Rather than focusing only on the score, you should use this overview to understand the overall condition of your website and identify priority areas.

Step 5: Analyze and fix key issues

Dive into the detailed reports to examine specific problems, such as broken links, duplicate content, or slow-loading pages. Focus first on issues that affect crawlability and indexability, as these have the greatest impact on search performance. Each issue includes recommendations, allowing you to implement fixes systematically.

Step 6: Re-audit and monitor progress

After making improvements, rerun the audit to track changes and measure progress. Regular audits help ensure that your website remains technically optimized as new content is added or updates are made. Over time, this iterative process allows you to maintain a strong technical foundation and support long-term SEO growth. Want to know how SEMrush can benefit your SEO strategies?
