Continuing to grow and increase the benefits of our websites is something that we all seek, so finding the best SEO tools is a fundamental job for anyone who wants to improve the ranking of their websites and blogs.

However, there is such a large number of free and paid SEO tools on the market that it is often very difficult to find the right one.

That is why in this article I bring you a compilation with the best SEO tools of 2020 so that from a single article you can choose among the best, SEO tools that best suits what you need.

Of course, I am not going to recommend something that does not seem good enough to me to be in this top or that I have not tried, so if you have any doubts about any tool that is not here, stop by the comments and I will try to help you.

The Best SEO Tools

best SEO tool

I already wrote an article where I was talking about SEO tools to find keywords.

But this article goes further since you will not only find seo tools for keyword research, but many of the tools that you will find here will do much more. 

And the best thing of all is that, although some are paid, they have a free version with limitations that will serve to test them before deciding to pay for one.

To the mess!

1. SEO Tool Suites


Semrush is one of the best-known SEO tools used by both SEO agencies and individuals who want to improve their website.

Personally, it is one of the ones I use the most (when I started the blog, I kept using it in its free version, despite the limitations it has).

You can use Semrush for free without any limitation for 7 days by registering here.

And you will ask yourself: « What can I do with this SEO tool?»

Semrush is an all-in-one SEO tool (also known as SEO Suite).

You can practically do everything: search for keywords, see the backlinks of a website, see the keywords by which a website or url positions, discover niches, analyze your main organic competitors, do a SEO audit of your website and improve SEO on page , monitor the position of keywords, etc.

From my experience, where you will most benefit from Semrush is in:

  • Search for keywords for your texts.
  • See the evolution of your website in terms of ups and downs of positions in Google and its organic traffic.
  • Study the competition to overcome it in Google and even to discover keywords that you do not use.
  • Analyze the SEM strategy (positioning of payment through ads in search engines, for example Google Adwords) of your competitors. It is one of the best seo and sem tools .

Therefore, if what you are looking for is to use a single SEO tool but that has everything, with Semrush you will not be wrong.


Ahrefs is the favorite SEO tool for many professionals in web positioning and online marketing.

It is practically in all the tops of paid SEO tools and it is not surprising because, although it was started as an SEO tool focused on the analysis of links both own and from the competition, it has now evolved to the SEO tool all in one more demanded .

Ahrefs offers tools such as a keyword browser, alerts about mentions, new keywords and links, SEO auditing, analyzing urls and websites both own and from the competition and a long etcetera.

In my opinion, Semrush and Ahrefs are the two best all-in-one SEO tools you can find. 

Although they are quite similar, each one has its pros and cons.

For example Semrush seems better to me to find keywords but Ahrefs seems better to me when it comes to seeing and analyzing the backlinks of a website.

The strengths of Ahrefs are:

  • Rank Tracker : monitor the position changes of your website for the keywords you choose.
  • Site Explorer : analyze any website you are looking for in great detail with metrics such as organic traffic, number of keywords, link profile, domains that link to you, anchor texts, competitor analysis …
  • The keyword explorer : shows you both the metrics of the keyword you choose (such as the difficulty in positioning it), other similar keywords with their corresponding monthly searches for you to incorporate into your texts or to serve as an idea for your articles.
  • The analysis of backlinks is much more complete.


Serpstat is an online SEO tool that goes unnoticed (for now) since it is beginning to enter the Spanish market.

Although it cannot be considered 100% as one of the free SEO tools , it can be used for free, although limited.

The truth is that it is an SEO tool that I discovered recently but that has impressed me a lot for the amount of information it provides.

From my point of view it has nothing to envy to the great competitors ; It has the main sections that cannot be missing in an all-in-one SEO tool:

  • Analysis of URLs and domains (both own and the competition).
  • Keyword Research: keyword search engine.
  • Analysis of links.
  • SEO audit of your website.
  • Rank tracker: to monitor your position increases and decreases in Google for different keywords.
  • Section to improve your SEM strategy.

However, it has one point in its favor that I cannot leave unnoticed: its price .

Unlike the most used SEO tools where you won’t find anything for less than $ 99 a month, Serpstat is the cheapest SEO tool

Their cheapest plan costs $ 19 a month or $ 15.20 a month if you sign up for a full year.

Without a doubt, I think that it is the greatest incentive to use a platform that has nothing to envy to the best SEO tools and above for much less money.


Mangools is a platform that has 5 SEO tools:

  1. KWFinder : keyword finder.
  2. SERP checker: Analyze the SERPs for a keyword with metrics such as DA, PA, TF, number of links it receives, etc.
  3. SERPwatcher : to monitor your positions in Google for specific keywords.
  4. LinkMiner: to analyze and find backlinks.
  5. SiteProfilerAnalyze an entire domain or URL (general metrics, links, traffic, most relevant and linked content, main competitors, etc).

Except SERPwatcher, the rest are free SEO tools (although limited unless you pay for them).

However, if you are looking for cheap SEO tools but with good quality, Mangools is undoubtedly the winning option .

Little is said about this SEO suite but its simplicity, its prices and above all its quality, make more and more SEO experts work with Mangools.

And I emphasize so much the quality that it has because it is the most reliable online seo tool in terms of the metrics it offers in the different sections. 

Regarding quality-price, it seems to me the best option to improve web positioning.


MajesticSEO has always been considered the leading SEO tool when it comes to analyzing backlinks.

Although it is true that in the other sections it does not stand out especially, it cannot be denied that the study of links in this SEO tool is the best .

Also, being cheaper than other SEO Suites (between $40 and $46), it makes many professionals hire MajesticSEO for its power to analyze links; or even opt for using it together with other SEO tools to cover all sides.


Although I have not personally tested SEOProfiler, I know with a good hand that it is a great tool.

If you move in the world of SEO or are in a group where these topics are discussed, it will be rare that SEOProfiler is not among the favorite SEO tools of many professionals.

Of course, with this tool you have covered all the essential sections: finding keywords, studying links, improving link building, analyzing the competition, monitoring keywords, etc.

2. SEO tools to modify the CTR

The SEO tools in this section are special since they will not improve the SEO on-page of your website. 

You could say that their function is something more than SEO blackhat since they are used to increase the CTR (click-through rate that they do in your Google results).

In this way, Google will see that if your search result has more clicks than one that is better positioned, it will be because yours is more useful for the user, and in return, Google will go up positions.

This newly created platform is not a common SEO tool.

With Serptrade you will not be able to search for keywords, see the links of your website or the position of your project in Google. 

However, it is the best free SEO tool to give your SERPs an extra push and improve positions.

Using this free SEO tool is very easy. It is based on a point system that users earn as they google and click on the search results of other Serptrade users.

Best of all, this “manipulation” of the CTR is done in a completely natural way, since it is real users who search their browser for the keyword you choose and click on your result in the SERPs.

Once registered on the platform you will only have to do two things: earn points (as I explained in the previous paragraph) and put the url of your project and the keyword that you want to position so that other users search for it and improve the CTR (spending thus the points obtained).

It is a free SEO tool but of course you can increase performance by buying points instead of earning them little by little.


SEOBOX is the only physical format SEO tool that exists.

It is a small device that you install in your home or office to automatically do certain tasks.

Although SEObox is now more of a suite of SEO tools , it started with its CTRbox module which is the one that manipulates the CTR of your search results just like Serptrade (the previous tool) does; only that SEObox does it automatically.

It also has other modules such as a keyword tracker to see how your position changes for certain keywords (rankbox) or a tool for local SEO (GEObox).

3. Technical SEO tools

Screaming Frog

Unlike the other SEO tools that I recommend in this article, Screaming Frog is software that you must install on your PC to use it.

Another difference from the rest is that Screaming Frog is very focused on the technical SEO of your website.

That is, with this SEO tool you will not find keywords or show metrics about the quality of the links (to give an example), but it will help you optimize SEO on-page from the more technical part.

It is the best tool for technical SEO. And I’m not saying it, but it is recognized by many SEO experts as the best in its field.

I do not earn a single penny for recommending this SEO tool but it is a tool that I use a lot and, despite not being very intuitive, it seems to me the best in terms of technical SEO.

It costs $149.00 a year but you can use this free SEO tool with limitations (scan up to 500 URL in the free version).

This program does an in-depth SEO audit of your website where you can get any type of information you can think of (broken links, images, internal and external links, titles, h1, h2, loading times and a long etcetera).

4. Other free SEO tools

Throughout the article, I have been putting what I think are the best SEO tools.

However, there are many other tools that are very good and that I cannot miss in this article, so below is a list of other free SEO tools  (and a paid one) that you can use in their different specialties.

Free SEO Audit Tools

As free SEO analysis tools, I recommend Woorank, a web page where just entering the URL you want to analyze will do a detailed analysis.

Free SEO tools from Google

If what we want is to “please” the big G so that it comes out on top in Google, what better than to help us with the tools that the search engine itself offers us, right?

In fact, they are so used that by now you should know them but just in case, here you have them:

Google Analytics

The quintessential web analytics tool. There is absolutely no one in the world of online marketing and blogging that does not use or has used this tool.

Google PageSpeed ​​Insights

Google PageSpeed ​​Insights is the SEO analysis tool for speed and load optimization of a web page.

Taking into account that loading speed is a fundamental SEO factor, this tool cannot be missing in your essentials.

Google Search Console

How could it be otherwise, Google has its own tools for webmasters. This is the case of Google Search Console.

With this Google SEO tool you can analyze from keywords and their position changes to inbound links or sitemap and robots.txt files on your websites.

Free SEO tools to find keywords

There are many SEO tools to find keywords.

Here are three extra free tools :


Ubersuggest is a free SEO tool to search for continuously improving keywords.

Although most of the SEO tools that I have already improved have this feature, with Ubersuggest you have the advantage that it is absolutely free .

Furthermore, its interface is very simple and intuitive. You will only have to put the keyword in the search engine and the platform will throw you various sections of information such as:

  • Metrics of the searched keyword (search volume, difficulty of positioning it, payment difficulty and the CPC).
  • Keyword ideas : a huge list (that you can filter) with different related keywords and their metrics so you can enrich your text with more keywords.
  • Serp Analysis : study of the first positions in Google for the searched keyword.

Seo Hero

SeoHero is a completely free SEO tool.

To get a “but”, it is a somewhat slow tool and not very visually pleasing but it is certainly an SEO tool to find keywords very, very complete.

Seolyze: the SEO tool to optimize your texts

Seolyze is a very particular SEO tool but without a doubt the best in its specialty.

It is a paid SEO tool designed to write (or modify) the best possible text to come out on top in Google.

This tool analyzes the texts of the first 10 positions of Google and shows you what words they have in common and how many times for you to adapt your text by adding the keywords in the exact proportion to go up positions.


Moz is the company that coined the terms of PA (Page Authority) and DA (Domain Authority) and, as it could not be otherwise, it also has its own SEO tools.

  • The famous Mozba r: tells you the PA and DA of any page you visit.
  • Keyword explorer – a simple keyword explorer. It leaves a lot to be desired compared to other free or paid SEO tools.
  • Link explorer: Previously known as Open Site Explorer. Quite useful to analyze the links of a domain or free URL.


And so far the article with the best free and paid SEO tools. I hope this top is useful for you when choosing the most suitable SEO tool for your needs.

Of course, if you have any questions or want to know my opinion about any SEO tool not included in the article, go to the comments and I’ll be happy to answer you.
