10 Best Technical SEO Tools to Audit Your Website

A routine technical SEO website audit is a must to ensure your website is working as it should. To do this properly, you need the right technical SEO tools.

Technical SEO audit tools are like the wrenches and hammers the mechanic keeps in a toolbox. They help you identify any potential errors or issues on your website so that you can fix them before they cause long-term damage. Website audits can also help improve SEO rankings and visibility. Generally, websites that load quickly and are well-optimized tend to get higher rankings and more organic traffic.

After comparing and reviewing several tools (their features, pros and cons, as well as pricing), we came up with 10 best technical SEO tools for auditing listed below. Use them to get the most out of your next website analysis!

What Are Technical SEO (Audit) Tools?

Before we go straight to some of the best technical SEO tool list for auditing and its comparison, let’s understand what these tools can do, especially when compared to other SEO tools.

Technical SEO tools for auditing are specifically designed to help you analyze your website for technical errors and issues. They can help you identify problems such as:

  • Broken links
  • Website architecture
  • Crawling and indexing problems
  • PageSpeed and mobile-friendliness
  • Incorrect or missing titles and metadata

This means technical SEO tools are used to improve the website’s functionality (as a whole), such as the crawl and indexing efficiency. Oppositely, on-page SEO tools concentrate on improving content relevancy by analyzing individual web pages.

What Are the Benefits of Doing a Technical SEO Audit?

Doing a routine audit on technical SEO performance will help you understand your website health. You can see which parts are already working and which need improvement. Put this in your SEO calendar every six months or a year, and don’t forget to compare it with the previous auditing results.

Here are some benefits of doing a regular technical SEO audit:

Optimized SEO Strategy

Auditing your website offer many benefits, including gaining insights into your website’s inner workings. Also, they help identify how your competitors optimize their websites so you can reverse-engineer their strategies.

You can also leverage some technical SEO software for keyword and backlink research. You can then use the results for keyword optimization and backlink profiling, making your on-page SEO and link-building efforts more effective. 

Save Time and Costs on Manual SEO Audits

Using tools to conduct technical SEO audits saves more time and costs than doing it manually or hiring professionals. Getting an SEO specialist to audit and developers to implement those recommendations on your websites can be costly.

However, when you use technical SEO tools to audit, you can automate the process. Many of these SEO tools are free or offer a free trial, so you can test them before buying.

Find High-Converting Keywords

With every SEO expert clamoring to rank for high-converting keywords, technical SEO tools can help you rank for them before they can. Technical SEO audit tools give you useful information like your competitor’s website performance, backlink profile, and keyword rankings. Ranking for these competitive keywords can get your content to generate more traffic. 

Gauge SEO Progress and Track KPIs 

Most SEO auditing tools generate automated reports that track your SEO progress over time based on the chosen key performance indicators (KPIs). This data can help you determine whether your website is running as intended and which parts need improvement. It can also help you compare your website to your competitors and make strategic adjustments to stay ahead of them.

Visualize and Conceptualize Data for Analysis 

Converting raw data into visual elements like charts and infographics can help you understand the data more easily and identify opportunities for improvement.
