🛠 8 technical SEO audit tools

Technical SEO data is essential for improving the user experience (UX) and simplifying the work of indexing robots. Here, I present 8 SEO audit tools that allow you to analyze points revealing the technical base of your website.

1. Screaming Frog

Screaming Frog allows you to crawl your entire site like a Googlebot. This tool is very handy for discovering many elements that will influence your organic search ranking (title tags, 404 errors, broken links, etc.). For $149 per year, you get a list of 26 technical criteria, while the free version only displays 7 pieces of information.

2. GTMetrix

GTMetrix provides a report on your site's loading speed. Once completed, the SEO audit tool gives you a list of task proposals to improve your performance. The free plan already provides good information and allows you to audit 50 sites per month. However, a pro account (starting at $128 per year) is more accurate, especially since you can define the geolocation of your target customer.

3. PageSpeed Insights

PageSpeed Insights is also very useful for checking the loading speed of your website. This SEO audit tool is entirely complementary to the one detailed before and provides accurate information on both mobile and desktop versions. This tool is completely free and very easy to use.

4. Mobile Optimization Test

The Mobile Optimization Test is a free SEO tool provided by Google. It quickly tells you if the mobile version of your site is compatible with display on smartphones and tablets. As a reminder, this point is very important, as mobile users now represent a majority of the traffic you receive.

5. Rich Results Test

Another free Google tool, the Rich Results Test is especially important if you have a store (e-commerce and physical store). This allows you to display in the SERP Google reviews, a price list, or opening hours.

6. Way Back Machine

Way Back Machine is an interesting audit tool because it allows you to see screenshots of the site's evolution. In addition, this free feature shows the history of server errors. Thus, if you notice a recurring issue, you know which technical elements to focus on.

7. Whois

There are many tools to discover the details directly related to the server. Personally, I like to use the free site to know the provider, IP, or even the use of a CDN. This kind of parameter is particularly useful when you audit a site that does not belong to you.

8. GeoIPView

GeoIPView is a free SEO tool that is very useful for knowing the geolocation of your site. This element is important because if your domain is not located close to your traffic source, the information transmitted to search engines and the loading speed may not be optimal.
