Are you looking for the best tools to improve your visibility on Google? In this article, you’ll learn about the best free or freemium SEO tools. In my last article on WordPress SEO , we saw how Google works. I explained to you that natural referencing was based on 4 main pillars:

Technical SEO: We are talking mainly about the accessibility of pages for Google and for the Internet user.

UX (user experience): your website must have good usability.
Content: when you combine quantity + quality, you have big SEO results.
Recommendations: the last pillar is to talk about yourself on the web
Quite naturally, I have classified this long list of free SEO tools by pillar. Let’s go!

Free SEO tools for technical SEO

Robots Exclusion Checker

The accessibility of the pages is essential for the Internet user as for Google. This little chrome extension allows us to see if the pages are accessible from Google’s point of view. As a reminder, Google works in 3 steps:

1. Page analysis: we can control the analysis of pages using the robots.txt file
2. Indexing of pages: you can control indexing thanks to the “No-index” tag
3. Ranking in search results: this is the object of all the SEO optimization of the site

Robots Exclusion Checker allows us to see if a page is blocked during the first two steps of Google. If one of the lights is red then Google will not be able to read the page properly.

Broken Link Checker

Broken link checker is a very interesting SEO tool that will analyze all the links on your website. For good visibility on Google, 100% of your links must be easily accessible , ie in code 200. If a link is in redirection (code 301) or in error (code 404), it is not ideal for Google. 100% of the entrepreneurs I have in SEO coaching have link errors. You probably have them too.

Broken Link Checker sends you an email as soon as it finds links that are not working well. You can then edit these links in a single interface. It is a significant time saving.

Screaming frog SEO Spider

Here is a complete SEO tool to do a technical audit of any website. Screaming Frog SEO Spider is a crawl (analysis) tool. It reproduces Google’s robot page analysis system. This allows us to see our site as Google sees it. Once the site has been analyzed, it is possible to see:

• Links and pages with errors (301 and 404)
• The weight of images
• The size of the tags
• The text of the tags of each page
• The links a page makes

Google Search Console

Search Console is a free SEO tool provided by Google, just like Google Analytics. If you had to install just one SEO tool in this list, it would be Google Search Console. It is an essential tool in natural referencing. Click here to learn how to install it on WordPress.

First, you will be able to send your sitemap (the sitemap) to Google. You will also be able to monitor your SEO: position, traffic, click-through rate and impression. But the most important thing is that you will above all be able to control that Google indexes your pages in its search engine. The “Coverage” tab is the most important of all.

Here are some other very interesting features:

• Ask Google to index a page in 3 minutes
• Ask Google to remove a page from its index

Free SEO tools for UX

Dareboost

This tool is very interesting for judging the loading time of a page. The tool gives us a score out of 100 and tells us the overall loading time. But that’s not all, Dareboost goes a little further by analyzing the ergonomics, quality or security of the page. The tool gives us a lot of advice on what has been analyzed. Unfortunately, most of this advice is quite technical. Simply use the tool to track your loading time.

The free version is limited to 5 analyzes per day by creating an account.

Think With Google

Here is a free SEO tool provided by Google. More comprehensive than Page Speed ​​Insight, the analysis focuses only on mobile load time. Knowing that more than 50% of Internet users are mobile users and that Google attaches great importance to the mobile version of a site, I find this tool really interesting.

In particular, it allows you to test your mobile with a 3G and 4G network, but also to compare several pages (internal or external). It is then possible to receive a full report by email with indications (in French) to improve the mobile version.

GTmetrix

GTmetrix is ​​similar to Dareboost in the different that the tool is really focused on loading time. For those who know a little about it, it is a very complete and very interesting tool. For the others, the tool gives us a performance rating (A, B, C, D or F), but the most important remains the “fully loaded time” . This must be the closest to zero. The recommended charging time should be less than 3 seconds.

I advise you to create a free account, you can control the settings and test the desktop and mobile version of your website separately. Please note, the default test region is in Canada. It must be modified to put “London”.

Ubersuggest – Neil Patel

Ubbersuggest is a well-known keyword research tool. It was bought by Neil Patel who made it a powerful tool. The online solution is mainly focused on keyword research and on the concept of the long tail (request of more than 5 words). For blogging content writing, this is a great tool. However, it is very quickly limited. Create a free account to have less limit.

Yooda Insight is the online solution I use most often in my SEO strategy. Like Ubersuggest, it’s a keyword research tool. The version is limited to 10 keyword suggestions. So it is better to use it to check the data that Ubersuggest gives. Yooda is indeed more complete and more precise than Neil Patel’s tool.

Answer The Public

Keyword research is a very important step in SEO so it is good to use multiple tools. Answer The Public is similar to Ubersuggest, it is a tool dedicated to long tail keywords and blog posts. Be careful to choose the database in French. Also, be sure to check Yooda Insigh for the popularity and competition of these keywords. This is indeed the weak point of the tool.
