Semrush Site Audit Tool Review & Tutorial for Beginners

Semrush’s Site Audit is another tool to analyze an entire website for issues related to technical SEO.

In this Semrush Site Audit review, you will learn how to use Site Audit and find out issues and fix them.

What is Semrush Site Audit?

Semrush’s Site Audit is a website audit tool by Semrush. It audits your website with 130+ on-page and technical SEO checks, including crawlability, internal linking, coding, hreflang, AMP, and HTTPS issues.

Since it’s a cloud-based service, you do not need to install it on your computer and run manual crawls, unlike WebSite Auditor of SEO Powersuite.

How to use Semrush Site Audit

You need an active Semrush account to start using the Semrush Audit tool.

It has got both free and premium plans. But, here is a quick overview of Site Audit limitations based on Semrush prices.

Max. number of web pages to crawl per project10020,00020,000100,000
Monthly PriceFree$119.95$299.95$449.95

Once logged in to your Semrush account, create your project. Give it a name and specify your domain.

Once done, click on the ‘Setup‘ button under Site Audit.


Or Click on the ‘Site Audit‘ link in On-Page & Tech SEO navigation section.


Site Audit Settings

A popout window will open. From there, you can configure Site Audit settings.

Domain and limit of pages

  • Crawl Scope: Select which domain (or sub-domain) should the Semrush should crawl
  • Limit of checked pages: Specify how many pages Semrush should check. The limit depends on your Semrush subscription plan. If you have a Pro account, you will have a 20,000-page limit.
  • Crawl Source: From where should the Semrush Site Audit tool start from crawling

Crawl source has four options:

  1. Website: Semrush will start from the homepage and go deeper from its linked pages
  2. Sitemaps on site: Site will find the order of sitemaps on your site
  3. Enter sitemap URL: Specify your main sitemap URL, and Semrush will start crawling from sitemap specifications
  4. URLs from file: Provide a list of URLs

Crawler settings

You will see two options: 1) User Agent 2) Crawl Delay

User Agent

Select which User-agent should crawl your site. SiteAuditBot-Mobile is picked by default. But you can change to another like GoogleBot-Mobile.


Suppose you have a website with massive traffic, and your web hosting plan has limited bandwidth. In that case, the crawl-delay setting will be helpful because you can configure the delay between crawls.

Allow/disallow URLs

If you want Semrush not to crawl any page, you can specify them here.


For example, use this option if you want to restrict Semrush from crawling any specific area of your site, such as Membership pages, thank you pages, non-public pages, OTO (One-Time-Offers) pages, etc.

Remove URL parameters

Define which pages with parameters should Semrush Site Audit skip.


Bypass website restrictions



Specify how often should Semrush site audit crawl your site. Unless your site is a bigger site publishing multiple pages per day, it’s good to set this to weekly.


Click on the ‘Start Site Audit‘ to proceed.

Depending on the size of your site, resources allowed in your hosting subscription, and the quality of web hosting, the finishing time may vary.

Site Audit Overview

Site Audit’s Overview section consists of several parts.


Site Health

A score developed by Semrush is based on the number of errors and warnings found on a site and their uniqueness. The higher the Site Health score better you are doing as a webmaster.

Takeaway: Try to improve the overall Site Health score by fixing issues associated with your site.

This is also an indicator of how many pages are on your site. The report breaks it down into five different groups:

  1. Healthy
  2. Broken

Which plan is good for using Semrush site auditor?

Essentially, the Pro plan is cost-effective if your site is no larger than 20,000 pages in total. For all other cases like managing clients’ site auditing works, Guru or Business plan is worth it. Furthermore, you can buy more pages to crawl from your Subscription info page.



There are several Semrush Site Audit alternatives with competitive pricing. Here are some competitors of Semrush that offer site auditing tools.

Semrush vs. WebSite Auditor

WebSite Auditor is offered as dedicated software for site auditing by SEO PowerSuite. It consists of many features and tools. You can learn more in this complete WebSite Auditor review.

Here are some key benefits of WebSite over Semrush Website Auditor:

  • WebSite Auditor is a software – You can run it on your PC or a virtual machine and run unlimited pages
  • Many customizable options – From crawler configuration to reporting settings.
  • TF-IDF – Learn which content your pages are missing with Term Frequency – Inverse Document Frequency (TF-IDF).
  • Keyword map integration – Audit content for better search engine performance
  • Site Visualization – Get a visual picture of your site structure in internal links, page views, and click-depth.
  • Content Editor – Edit content within WebSite Auditor with SEO recommendations.
  • Generates XML Sitemap, Robots TXT files – Currently Semrush Website SEO Audit tool does not generate XML sitemaps or robots.txt files according to custom filtering.
Content Editor is a bit similar to Semrush SEO Writing Assistant. A perfect option if you run an HTML website

Is Semrush Site Audit worth the cost?

It is no debate that it’s required to have any sort of website auditing tool in your arsenal. But, the question is whether Semrush is worth it when considering many contenders.

If you review Semrush deeply (price versus features etc.), you will come to know that it offers tremendous value under every Semrush pricing plan. Whether Pro, Guru, or Busines, Semrush has every tool you need.

Obviously, there are some disadvantages of solely using Semrush Site Auditor instead of a dedicated site-auditor like WebSite Auditor, such as not getting TF-IDF keyword reports and essentially more robust features.

But, if you are a solopreneur and are looking for an excellent tool to audit a site without spending much, Semrush is worth it as you get 40+ more powerful other tools to grow your business online.

However, if you have a website with huge pages or manage multiple clients and want a more robust platform, I recommend WebSite Auditor. Its Enterprise plan costs $299.95 per year, and you get to crawl unlimited pages and allows using proxies and different user agents than the Semrush Site Audit tool to speed up the process.
