Today there is no doubt that the Google Chrome browser is the most used. And, how could it be otherwise? In the world of blogs and SEO, we can take advantage of it to improve or retouch the design of our blog thanks to its extensions.

In this article, I will show you what best SEO Chrome extensions you should have installed in your browser to get the most out of your website or blog.

To do this, in the article, you will find two distinct sections.

  • SEO extensions for Google Chrome.
  • Chrome extensions for web design.

But for the novice, let’s start at the beginning …

What is a browser extension?

By blogging and minimally understanding browsers and online marketing, you should know what a browser extension is.

However, if this is not your case, do not worry. Here I explain it to you.

An extension is like a plugin for the browser that you can locate in its toolbar. This is, just as WordPress plugins give extra functionality to your website, extensions provide an additional function to your browser; it’s that simple.

And as you can imagine, there are countless extensions and each with its functions.

How to install an extension in Google Chrome

Installing an extension in your Google browser is very simple.

You have to click on the browser options (the three dots below the X where the window closes) and go to More tools> Extensions.

A tab will open that will show you a list of all the extensions you have installed in your browser (from here, you can also uninstall the ones you don’t want) and, at the bottom, a link says: «Get more extensions.»

Clicking there will take you to the Chrome web store to find most of the free and paid chrome extensions (as if they were the WordPress plugin search engine).

So the only thing left to do to add an extension to Google Chrome is put the name in the search engine, click, and give ” Add to Chrome.” 

And now that you know the basics let’s get down to business!

The best SEO Chrome extensions for online marketers

Best SEO Chrome extensions

The truth is that there is a wide variety of extensions, and many of them do the same or very similar things, so I am going to put them by categories and, in my opinion, those that I consider being the best.

Chrome extensions for SEO

We start with the SEO extensions that I use the most and the ones that I have the most because I consider them very useful to improve the ranking of my blog:

1. SEOquake

SEO Quake is the quintessential SEO extension. Just by telling you that the guys from Semrush created it, you can get an idea of ​​all the potential it has.

Once installed, the following icon will appear (surrounded by red) in your upper bar: 

And what does this extension do?

Well, it does an SEO analysis of the web page you are visiting at that moment. So, as you can imagine, it is helpful to analyze your website and spy on the competition and overcome them.

You could even do a complete guide on this extension, but since it is not the objective of this post, I will quickly summarize it for you.


As you can see in the image, clicking on the SEO Quake icon will open a window with different data from the web you are visiting.

Depending on the tab you are in, you will have different data:

  • Page info: title, meta description, number of internal and external links, keyword density, indexed pages, Alexa rank, I like you and shared on social networks …
  • Diagnosis: it will do a small SEO audit where it will tell you a list of successes and errors that you have on the web so that the solutions (for example, length of the title, the ALT attribute of the images, if you have the robots.txt file and the sitemap.xml, etc.).
  • Internal: it will show you a list with all the internal links of that page, and it will tell you if they are dofollow or nofollow, the format (image, text, …), and some other data.
  • External: basically the same as the previous section but with external links, that is, with those that leave your website to other websites.
  • Density: analyze the text of the page you are viewing to see which words have the highest density in your text.
  • Compare URL: analyze as many URLs as you put in the list and compare them in different parameters such as number of indexed pages, number of backlinks, or the ranking in SEMrush.

In addition to all this, if you activate the SEO Quake extension, each time you do a Google search, a small box will appear below each result where analysis of different metrics seems so that you can get an idea of ​​the authority of each site:

SEOquake serp result

In the parameters section, you can choose the parameters you want to appear in the box (for example, number of backlinks, indexed pages, the rank of SEMrush, etc.).

Also, from the control on the left, you can export all the URLs that appear in the serpin CSV format if you want to analyze them one by one.

2. MozBar

Another chrome extension that is not missing in any SEO is Mozbar.

Do you know what is PA (page authority) and DA (domain authority)?

If you like SEO or have read about it, I am sure you have read something about these metrics created by Moz (although I wouldn’t be so sure about the importance that you must give to these values).

With this extension, you can see these two parameters quickly and without leaving the tab in question. Of course, you can do it with any page or website.

In addition, another very useful option that this tool has is that it shows you in striking color the dofollow, nofollow, internal, and external links of the page you visit.

To do this, you have to click on the pencil icon in the Moz Bar and select what you want to color.

3. Alexa Traffic Rank

This extension is not used as much since the Alexa ranking is not used too much, but it gives you an idea to compare other websites with yours and see if they have higher or lower traffic than yours.

It gives you the world and national ranking that occupies the web you are visiting in the Alexa ranking.

In addition, it also gives you the loading time and similar pages according to your theme.

4. LinkMiner

This extension seems very useful to me to find broken links both on your website and on other websites. 

It tells you which links are working correctly (coloring them in green ) and which ones are not ( red ).

One strategy to get links that sometimes works is to look for broken links on other websites and tell your webmaster to change the link to put one on your website.

It doesn’t always work, but you don’t lose anything by trying, do you?

Of course, you can also use it to analyze the links on your website.

Keywords EverywhereKeywords Everywhere is probably one of the best SEO Chrome extensions when it comes to finding keywords.

Of course, for now, it is the only one that I do not consider a «must-have» because it is not yet fully implemented in Spanish and does not go as well as with words in English. But you can still use it to find some extra words.

It has many utilities that you will have to discover for yourself although here you have the most important:

  • It tells you the monthly volume of searches for any word you put in the Google search engine (and the suggestions that appear at the end of each page of Google results).
  • The level of competition for these keywords.
  • Your CPC (Cost Per Click). Essential for Adsense and to find niches.
  • It integrates perfectly with other tools such as Google Analytics, Google Search Console.
  • It is also very useful for searching keywords with the volume of visits in pages like keyword shitter or answerthepublic.

5. Open SEO stats

As its name suggests, Open SEO Stats is a free  “all in one” SEO extension for Chrome where through various tabs, you can see statistics or “stats” of the page you are visiting.

It is a complete tool since it offers you a wide range of information.

You can see from the pages indexed in each search engine to the content of each meta tag (title, h1, h2, alt, etc.), loading speed, outgoing and internal links (do-follow and no-follow), etc.

Chrome extensions for web design

6. Page Ruler

Page Ruler is nothing more than an extension that serves as a ruler to measure web spaces in pixels.

You have to click on its icon (two rulers forming a right angle) and draw a line, a square, or a rectangle on what you want to measure, and it will tell you both the pixels it occupies and the pixels that are on the sides and by above and below.

Very, very useful for the layout of landing pages and landing pages.

7. Web Developer

This extension should be mandatory for everyone who dedicates or likes web design because it is the most complete. 

If you want to know any information regarding the code, images, texts, links, etc., of a web page, you will find it with this tool.

The only downside is that it is in English, but it has many functionalities, a special mention to the CSS part for web design and the images tab to see these and their ALT attributes.

8. Eye Dropper

Eye Dropper is a very simple but very useful extension in web design.

How often have we wanted to see what exact color a part of a website or an image of a page or blog has?

Well, to avoid having to do silly things, with this simple extension, you can know the color of any part of a web page.

eye dropper chrome extension

You have to click on “Pick color from the web page,” go to the area you want to get the color from, and on the right side, it will tell you the color in different formats so you can put it in your style file, in photoshop or wherever you want.

In addition, the last used colors are saved so that you do not have to look for them again on the web where you took them.

Other beneficial Google Chrome extensions

In addition, there are other series of addons or extensions for Google Chrome that you cannot ignore if you have a website or a blog.

Of course, there are many more, SEO and web design and utilities, but I have decided to put the essential ones because otherwise, it would be an enormous article.

Don’t forget to leave a comment if you can think of any more in this article.

We go with the extensions with other utilities :

9. LastPass

LastPass is an extension that will serve as your password manager and administrator.

From it, you can save all your passwords and use them from any computer where you have this extension installed.

As you can see, it is a very useful extension if you are one of those people (like me), who use a lot of passwords, and there are times when we doubt which one is for each site.

10. Honey

Honey is an extension that searches for discount coupons for you.

It does not work with all stores and internet websites, but it does for a large majority.

I use it a lot, for example, when I go to buy a domain. Before buying it, I always look at this extension because it almost always has a discount coupon that lowers the price by a few euros.

And now I am going to tell you a little trick/secret: although you do not think of this option at first glance, I use it a lot to improve the on-page SEO of my website.

To improve the SEO of my already written articles, I am analyzing them both with Google Analytics and with the Google Search Console (and other tools), looking for missing keywords or increasing or decreasing the keywords I already have.

So I use these notes as a record of each article.

For example, if I now analyze an article from months ago and conclude that I have to put the keyword «Google Chrome» more times, I put them in the text and immediately write a note with this extension where I placed and the date.

It will help me know where I put that keyword and when. And I can also check the ranking after some time whether it improved it or not. 

If it has improved, I leave the text as it is, and if it has worsened, I remove the words or try another combination to see if it improves.

And so far, today’s article with a built-in trick!
