Web Developer

Web Developer is an essential SEO extension for Chrome, easy to use and one of the most complete multitasking tools.

The information it displays is very extensive and has options of all kinds, with web design and SEO being its main incentive.

Its operation is very simple, as each extension is very easy to use, just write the name of the extension in the search engine, click add and that’s it.

Once you have installed the tool, a kind of configuration wheel will appear in the top bar, click on it and you will see how to improve your website using its options.

As we have told you, the web design functionalities are also the strong point of this extension, since, for example, it allows you to play with cookies, use css functions, etc.

But since we have come to talk about web positioning, we are going to see the options that will help you with it:

► Images

The images are very important for SEO, the size, the weight and that they have the ALT attribute assigned are an important part of the positioning.

Achieving a good speed of a website depends largely on the optimization of the images.

  • Display alt attributes: this option shows you the alt texts of the images, you know, if you need to fill any of them, do it.
  • Display Image Dimension: It will show you the  real size of the images.

Very useful for detecting images that are larger than the size that is being shown to the user, in such a way that you should optimize each photo that you have scaled.

  • Display image packs: shows the dimensions of each image, as well as the assigned name (it is important to give information to search engines, rename the image with a coherent text)
  • Outline images width empty alt attributes: This function indicates with a red frame the images that do not have an alt assigned.

► Information

The links are a very important part and are shown by some of the options in the list of applications that we show you, as well as headers or titles.

  • Display links details: shows information of all the links of the page that you are viewing, in this way you can analyze where they point and if they have some type of attribute assigned.
  • Display title attributes: Although not as important as the ALT, the title adds up if you add it to the image field, this option displays this.
  • Views document outline: important tab since at a glance you can see how you have distributed any page at the header level (h1, h2, h3, etc.)
  • View link information: list of all the links of the page that you are analyzing, this is good to control the internal linking.
  • Outline sternal links: mark in red the external links of the page you are viewing.

► Tools

This part has several functions but for SEO the following is useful:

  • Validate Accessibility: Shows certain header, ALT, or repeated text errors.

Although this option is a bit extreme, when it comes to giving you improvement tips, it is fantastic to see the header structure or again the alt of the images that you have or are missing.

Webdeveloper checklist check

It is an extension for Google Chrome web analytics. It is simple, fast and very useful, since it shows a basic technical summary of the web on a simple screen.

This extension shows you if everything is correct or if there are missing features that help the positioning of a website. It shows important aspects such as: if the web has the robots.txt, accessibility, alt attributes, Google Page Speed ​​score, etc.

Although simple, it is always good to use it on time. 

Extensions to track links in Chrome

It is very necessary for Web positioning to be able to detect 404 errors and study the link to each of our pages and articles.

With them you will have it very easy, since you will see all these things at a glance.

Check my links

Check my links is one of the best SEO extensions to detect broken links or 404 errors.

It is very easy to use since simply clicking on the icon of the installed extension shows the page links that are correct or redirected in green and those that are broken in red.

These 404 errors that the extension detects, you must fix by removing them in Google search Console or by performing a 301 redirect through a plugin or manually by editing the Htaccess file.


Nofollow is another SEO extension, which is displayed in the browser through a link-shaped icon.

This exceptional tool for positioning shows graphically through red boxes, the links of the page cataloged as nofollow.

It is not necessary to touch anything, since automatically, unless you deactivate it, it will show in each web that you go which ones have this type of attribute.

As you have read, it is an essential browser tool.

There are other similar ones, but this one does its job perfectly in a simple and fast way. 

Link parser

Link Parser is one of those extensions that you will use very often for your own page or to analyze your competition.

The operation is very simple, once installed and activated, access the icon and in configuration you can assign different colors for the links:

  • Internal Dofollow.
  • Internal nofollow.

Extensions to perform SEO audits in Chrome

Carrying out a good audit of the project you are working on is vital.

There are many tools to do it, you just have to browse the Internet to go crazy, the best thing is to have an extension to do it, as we told you.

Although there are many paid ones that do a complete study, these tools do a very good job.

Let’s see them!


Seoquake is a veteran tool that, as an extension, does a very good job of positioning a website.

Examine the page on which you want to carry out a study, by clicking on the icon installed in the navigation bar.

We highlight 4 options of this tool:

► Page info

A new tab will open where you can see the title, description and the number of dofollow and nofollow links, age of the domain, social networks and general data extracted from the SEMrush tool, which you will surely know.

The most interesting part is the density, although the keyword repetition limit is not as uncontrolled as it was years ago, nor as controlled as it was recently. Nowadays naturalness prevails more.

My recommendation is still to use it between 1.5 and 2%, but this depends on the niche and how the competition in each sector acts with regard to those keywords.

In this section you can see the density of each word and the number of times it is repeated.

Other interesting options within this tab are:

  • Parameters: where you can see general information from social networks, links based on SEMrush or Google cache.
  • Traffic analysis: shows the different sources of web traffic, number of visits or ranking.

► Diagnosis

This section makes you a “mini-audit”, but it offers interesting information since part of the errors, which can be found, must be solved since they are basic

It also measures other parameters such as: title and meta description densities, headers, ALT texts, text ratio, html (you should include more text to compensate), structured data, robots, txt, sitemap, Twitter Cards etc.

► Density

Extensive section to see the density of all the words and especially the prominence of these keywords (importance of a word within a text based on position and style).

You can also filter and indicate that it shows you groups in tables of 1, 2, 3 or 4 words.

► Domain comparer

It allows you to compare several domains to see the different indexing in Google, Bing, age of the domain or rankings.

*If you click on the configuration wheel you can make different specific configurations

Seoquake is a very powerful tool that also allows you to export the data for the study

Likewise, if you activate the side tab in the serp, below each result of each url it shows information from the different sites. 

Open SEO stats

Another simple extension that, as an option box, allows you to display them to see interesting information on the web at a single glance.

For example you can see:

  • The robots.txt file
  • General information of each page.
  • The DNS of the web.

  • Estimated web speed.

This has an easy solution with the following extension:

Keywords everywhere

Keywords everywhere is a very powerful extension that offers exact keyword planner data in Google Chrome

The problem is that it does not do it for the Spanish language, but even so, it is an excellent tool, because it allows you to focus more specifically on the number of more or less interesting keywords to attack by volume.

It is a very good tool and it is also free, which offers the number of searches not only for the Keyword Planner, but also for other platforms such as “Answer the public”, Ubersuggest, keyword shitter or Google suggestions.

It is important to take these values ​​into account to study the degree of competition when attacking certain keywords.

Although these data can be distorted with incoming visits, it is true that it is a very valid tool for making estimates.

This extension basically tells you if that URL in AMP is working fine or not.

The extension will automatically reflect by means of a green lightning bolt if the AMP implementation of that url is correct.
