SEO Audit Tools Buyers Guide 

Before you go out and commit to a monthly payment plan for an SEO audit tool, there are a few factors to be considered.

Below you’ll find everything you need to know before you decide what SEO auditing tool you are going to commit to. 



The tools offered by the SEO auditing tool is one of the most important factors to consider. Look for tools which are going to enhance your website in all aspects.

Whether it aids in keyword research, backlinking, redirects or competitor research, the services should fit your needs and help you improve your SEO ranking. 

Some SEO auditing tools may offer more niche features such as keyword research data for PPC (pay-for-click) or social media management.

These features are great as they take more tasks off of you and give you the necessary information to maximize your SEO. 

SEO auditors which integrate the use of Google Analytics and Google Search Console are also beneficial.

This keeps everything you need in one place. You can quickly see which changes need to be made to your website for growth and development. 

Each feature should add to your website’s SEO ranking. This can be as simple as making a few changes to your keywords or may require some more effort.

But at the end of the day, you will find your website at a higher ranking and see steady growth for your website. 


When deciding which SEO auditing tool to use, pricing can be a deciding factor.

With the majority of tools available opting for monthly payment plans, it can quickly become a large expense. 

There are many SEO audit tools available which are free. However, you may not have access to all of the intricate services available with a premium plan. This could hinder your website’s growth. 

It is becoming increasingly common for SEO audit tools to offer a yearly flat fee rather than a monthly fee.

This helps keep your costs down in the long run as the upfront expense will not change over the course of the year like monthly costs can. 

This decision can only be based on the budget allocated to an SEO audit tool. Although they don’t have to be expensive, choosing a premium plan may be a better fit for your needs. 

You can also request a trial run of the auditing tool. This will give you insight into the functionality of the tool and whether it is worth the cost.

However, some SEO auditing tools do not offer this service and require payment upfront which can be off-putting to some customers.

Data Accuracy  

While the analysis and recommendations completed by SEO auditing tools are helpful, they have to be accurate.

The purpose of these tools is to make sure there is less work for you to do, not create more. 

Reliable tools will provide full analysis reports of your current SEO with accurate identification of any issues within your site.

Whether it is the length of the article or if there are broken links still active within your site, this can be crucial in increasing your SEO ranking. 

Within collecting accurate data, the way this is displayed is also important.

You will find that most SEO auditing tools present their data in graphs and diagrams.

This is because having data displayed visually is much easier for everyone to understand.

Whether you have a decade of experience in SEO or are only beginning to learn. Make sure the data you are collecting makes sense to you. 


Finding the SEO audit tool which has all the features you need can seem like a dream.

Then you go to use it and nothing makes sense. Having a simple user experience is important in order to get the most of your SEO audit tool. 

If you are a beginner you may prefer tools which have everything in one place such as a dashboard.

This can make it easy to navigate and begin implementing a schedule to keep up-to-date with your website’s SEO. 

Or you may prefer something more advanced which has detailed reports.

This can be a little more difficult to navigate, however, will give more in depth information.

From here you can make more informed decisions on your website’s SEO than simpler tools that may be less accurate. 

Try a few SEO auditing tools and find which styles you can work easiest.
