The Best 27 Free SEO Tools for Search Engine Optimization

Free SEO Tools for Search Engine Optimization

This article will give you the best, most useful, and above all, free SEO tools.

The work with SEO has many nuances. That is why we have selected a number of tools that are the most useful and do not cost you anything. The tools are divided according to their purpose and tell a short story about each.

They are selected according to the following method:

  • Tools must have a free functionality
  • They must be relevant and popular
  • They must give you insight that you can put into practice.

Some of the most common SEO tools are Ahrefs and Semrush. When I do free SEO analyses for interested companies, I also use, e.g., Ahrefs.

 However, both tools quickly become expensive to deal with. But if you have an ambitious SEO setup where you want to be at the top, you should probably invest.

But if your SEO journey is beginning, you should start here. You first get our recommendation for the absolute best free toolbox for SEO. This is followed by a nuanced review of 27 tools, each capable of slightly different things.

What are the most effective SEO tools in 2023?

The best SEO tools we recommend in 2023 are Google Keyword Planner, Ahrefs Backlink Checker, Ahrefs Webmaster Tools, Yoast, and Google Search Console.

Tool for keyword analysis: Google Keyword Planner

Here you get a solid opportunity to find out the search volume and degree of competition and get inspiration for alternative keywords.

And since it’s direct from Google, you know you can trust the data. In addition, many people already work with Google Ads, which is why it is easy to use Keyword Planner.

Link Analysis Tool: Ahrefs Backlink Checker

With Ahrefs Backlink Checker, you get access to the strongest link database on the internet. Besides Google’s own, of course.

Tools for technical SEO: Ahrefs Webmaster Tools.

With Ahrefs Webmaster Tools, you get a solid introduction to technical SEO. It analyzes your website for the most serious errors and tells you how to fix them.

Tool for content: Yoast

With Yoast, it’s easy to ensure that all your pages are as SEO-optimized as they should be. Yoast won’t tell you exactly how to hit the search intent but acts as a strong checklist to ensure that the lowest-hanging fruit is picked.

Tool for data: Google Search Console.

Data you can’t question. With GSC, you get access to key SEO metrics such as views and clicks, the ability to keep an eye on indexing and other technical issues – and best of all, the data is direct from Google’s search results pages, so you know it fits.

If you use these five, you’re well on your way – regardless of whether you’re new to the world of SEO or need to keep up with what your agency is doing.

If you already know these five – and feel they are missing something –I would encourage you to read on. And read our full guide on “The 15 Simple SEO Trickstoincrease your website’s organic traffic

Keyword analysis tools

When you have to do a keyword analysis, it is important to keep in mind which keywords you can work with.

 Which of these tools is best depends a lot on your needs. You can advantageously use several of them to counteract the limitations of the free editions.

1.     Keywordtool.io

An easy way to generate hundreds of keyword ideas

Keywordtool.io uses Google Autocomplete to show you many suggestions for other keywords you can use when doing your keyword analysis.

Limitations: The free version has limited search volume data access.

2.     Ahrefs Keyword Idea Generator

Get data on the best keyword ideas

Ahrefs is one of the world’s best SEO tools and is also my favorite and used – both when we do an initial free SEO analysis and go in-depth with the SEO work.

But to get full access is quite expensive. However, Ahrefs also has a large number of free tools, including Keyword Generator.

Limitations: You can only get data on the first 100 keywords

3.     Ubersuggest

An all-around SEO tool that can tell you about keywords, links, and track ranks

Marketing guru Neil Patel is behind the ambitious project Ubersuggest, which aims to help provide more SEO data.

 It’s quite cheap for full functionality, but if you don’t do a lot of SEO, you’ll also get far on the free version.

Limitations: Only three daily searches on keywords and domains

4.     Answer the Public

With Answer The Public, you tap directly into your audience’s questions.

Who, what, when, why? Questions form the cornerstone of people’s search for information. And no tool makes it more clear than Answer The Public, which can give you a wide range of relevant questions and comparisons based on a single keyword. These are connected to a nice and understandable graphic.

Limitation: 3 daily searches

5.     Moz Keyword Explorer

From an old familiar in the SEO world comes Moz’s Keyword Explorer

Moz’s database is one of the largest, and its free version also provides an unmanageable amount of data. Use it to lay out a clear keyword analysis and SEO strategy. 

Limitation: 10 free searches per month, and you must create an account

6.     Google Keyword Planner

Google’s tool for Ads is a powerful weapon in SEO

Sometimes you have to go straight to the source. Google’s Keyword Planner gives you data on the latest search volume, generates thousands of keyword ideas, and, through the CPC price, can tell you how commercial a keyword is.

Limitation: None. But you have to add a credit card. It doesn’t deduct any money.

7.     Semrush

One of the most well-known all-around SEO tools in a streamlined free version

With Semrush, you can get data on keywords and links and track your rankings for free. At the same time, they also have a strong research tool that can provide good ideas and input for your content marketing strategy.

Moz provides in-depth data that you can export and use however you like. In addition to the number of links, you also get an insight into anchor text, historical developments, and much more.

Moz differs from Ahrefs by providing access to more data types, but the limitation is on consumption. In addition, you get access to Moz’s sophisticated Domain Authority metric, which can be a good guideline in link-building work.

limitation: 10 monthly searches (not shared with their Keyword Explorer)

10.                        Disavow Tool

Google’s Disavow tool is not for newbies in SEO but can work wonders for sites that are heavily affected by spam.

It’s a sub-function for Search Console (which we include in the list further down), but Google’s Disavow gives you control over whether you want to acknowledge or reject links you’ve received. You should always think carefully and contact your nearest SEO expert before you get started.

Tools for technical SEO

Technical SEO is – to put it bluntly – very difficult. Fortunately, there are many free tools that let you keep an eye on your website’s technical health, its speed, and how it’s structured.
