Best Free and Affordable SEO Tool

You still want to optimize your page but you don’t want to get the paid tools or you want to test some good tools before you buy. Here we shall look at the best free and affordable SEO tool that you need to have successful on-page optimization.

On-page optimization is vital for getting strong domain authority, on top of off-page optimization. Digital marketers continue to rely on tools that can optimize a website’s rank in the searches of visitors and potential customers.

This has become even more crucial for those focusing heavily on content marketing. It’s important to identify the right tools in the flooded market to help in the optimization process.

We have identified several crucial tools for use in the on-page optimization of our pages that are either completely free, offer free and paid versions or may offer the user a trial period of several days

Best Free and Affordable SEO Tools you Should Use

1. Google PageSpeed Insight

Test your site speed for mobile and desktop using the google free tool. PageSpeed Insights analyzes the content of a website and then generates suggestions that you can use to make that site faster. It’s completely free with unlimited searches.

You can click on the mobile or desktop buttons to check the different speeds. The page speed colours appear in different colours indicating different speed ranges as follows:

Red – 0-49

Orange/Amber – 50-89

Green – 90-100

Your goal is to ensure that you have a green colour, especially for the mobile platform.

Why not for the desktop platform? so you ask, most of the time when you have good speeds for mobile you will be having even greater speeds for desktop.

Also, I cannot overemphasize the fact that more than 2 billion people used mobile devices in 2020 to access the internet and they might be more than desktop users by 2023. You don’t want to miss that market.

If you scroll down, you will be able to see the summary of your page speed, for your action.

2. Gtmetrix Speed test tool

If you need a more detailed tool, to help you improve your speed, then Gtmetrix is the silver bullet for you. Gtmetrix has both free and paid versions which allow for monitoring and API credits.

The free version is however good enough for manual testing with an offer of 30 weekly on-demand tests,10 daily API credits, 1 monitoring slot and 1-month data retention.

However, you need to learn how to use and interpret the result to have any meaning and use them to your advantage.

Gtmetrix awards a “Gtmetrix grade” and some “Web vitals” metrics. Gtmetrix grade is an assessment of your overall page performance and reflects, both, how fast your page loaded for users, and how well it’s built for performance.

Web vitals on the other hand represent a small set of core metrics that indicate whether you’re delivering a fast and (what Google calls) a delightful experience to your visitors.

Gtmetrix allows you to perform the following

  • Select the test server location
  • Compare your results with other sites,
  • Set up alerts and monitoring
  • Create a page-load video to see exactly how your webpage loads
  • Download pdf reports
  • Select the browser to test from either chrome or firefox
  • Select the device to test from i.e. desktop or mobile
  • Adblock Plus to evaluate the effects of ads on your site speed

To get higher priority and faster tests create an account though it’s not a must.

Final Thought

While discussing Best Free and Affordable SEO Tools, it’s simple and basic knowledge that free SEO tools are limited compared to paid tools.

That’s not to say that free tools don’t have their place. But the number of keyword ideas and data they give access to will always be slim in comparison to paid tools.

Most Important: free keyword tools are good when starting your SEO journey, but as you grow your site, you’ll need paid tools to keep up with the competition and the large number of searches involved.
