If you work in digital marketing, and especially in SEO, you have probably noticed that you need to use different tools and add-ons to analyze every aspect of a website.
One of the best ways to save time and work more efficiently is to use browser extensions that quickly show the information you need.
In this article, I’m going to show you the 10 free SEO extensions for Google Chrome that I use most often. To install any of them, you just need to open the Chrome Web Store and search for the extension you want.
I have also written an article about the best web analytics extensions for Chrome that I use. It is worth checking out if your day-to-day work also involves digital analytics tasks.

What are the benefits of using free Chrome extensions for SEO?
The first thing to keep in mind is that Chrome extensions will not do the work for you, nor will they produce a ready-made list of issues to fix.
What they do offer is quick and convenient access to different aspects of a website. That is their main advantage in SEO: the speed with which you can review certain elements of a site that affect organic visibility.
For example, if you want to check a page’s meta description without using an extension, you would need to open the source code and search for the relevant HTML tag manually. With the right extension, that information is shown instantly and in a much more user-friendly format.
Top 10 recommended SEO extensions for Chrome
Below are the 10 SEO extensions that I think should not be missing from your Chrome browser. Each one offers different features that can help you quickly analyze some of the most important aspects of a website in your day-to-day work as an SEO specialist.
1. SEO META in 1 CLICK
SEO META in 1 CLICK shows all the information available in a page’s meta tags in a single dropdown: title, description, URL, canonical, robots, and more.
It also includes additional tabs where you can review the page headings and their order in the HTML, the number of links and images on the page, and Open Graph information used by social networks.
On top of that, the extension provides quick links to external tools for other types of checks, such as page speed analysis, structured data validation, or mobile page experience review.
2. Robots Exclusion Checker
Robots Exclusion Checker performs a real-time check of five key elements related to a URL’s crawlability and indexability.
The extension shows whether the URL returns a 404 error, whether it is blocked by the robots.txt file or by a robots meta tag in the page code, whether there is an x-robots-tag header blocking crawling, and whether the canonical tag points to the same URL.
Depending on what it finds, the extension icon changes color to reflect one of three states: red, yellow, or green. Green means there is no obstacle preventing Googlebot from crawling the URL. Yellow means the page has an issue that could affect indexation and should be reviewed. Red means one of the previous elements is preventing the URL from being crawled properly.
3. Link Redirect Trace
Link Redirect Trace analyzes a page’s redirect path. In other words, it helps you detect whether a page contains any type of redirect.
If you access a page that redirects somewhere else, the extension shows every step the browser followed and also provides useful information about the HTTP headers and status codes involved.
It also offers additional information about the canonical tag, the robots.txt file, and the page’s external links, although its main strength is redirect and HTTP header analysis.
4. Web Developer
Web Developer is not built exclusively for SEO work. It provides all kinds of tools for web developers, but many of its features are extremely useful for technical SEO as well.
Among its most useful functions are the ability to disable JavaScript on the page to assess whether Googlebot might have trouble crawling it, modify CSS, delete browser cookies, inspect image information, reveal details about elements in the HTML, outline different page blocks, and validate structured data.
5. Hreflang Tag Checker
Hreflang Tag Checker is a very simple extension that lets you see whether a page contains hreflang tags for different languages.
It also checks whether those tags are implemented correctly across the alternative versions, which makes it easier for Google to understand the site structure and connect the different content versions.
6. Keywords Everywhere
Keywords Everywhere helps you carry out keyword research directly from Google’s search results.
You simply run a search and the tool shows a list of related keywords, long-tail keywords, and terms that appear in Google’s related searches section.
The extension also adds a trend graph showing how search interest has changed over time. In addition, for each Google result you can see traffic and ranking keyword estimates, both for the specific URL and for the website as a whole.
Finally, the tool also shows useful information on YouTube, which makes it especially valuable if you also work on visibility there. It can display an estimated optimization score for the video, daily views, the number of channel subscribers, and how specialized the channel is in the topic covered by the video.
7. Wappalyzer
Wappalyzer is a browser extension that detects the technologies used on a page.
It can identify the CMS behind the site, installed analytics tools, JavaScript frameworks, video players, programming languages, fonts, CDNs, databases, WordPress plugins, and much more.
As you can imagine, this is especially useful when analyzing competitors and trying to understand how their website is built. You can quickly see whether they are using a CMS or a custom build, which tools they have in place, or whether they rely on a CDN.
8. View Image Info (properties)
To use View Image Info (properties), all you have to do is right-click on any image on a webpage and select the extension from the menu.
What it does is show all the properties of the selected image, including the URL, dimensions, format, file size, ALT attribute, and an image preview.
Keyword Surfer
Keyword Surfer works directly inside Google Search.
When you perform a search, the extension adds a panel on the right-hand side of the results page showing keyword ideas related to the query together with their search volume. Those keywords can then be saved and exported as a CSV file for further analysis.
The extension also adds information to the search results themselves. More specifically, it shows the estimated monthly traffic for the whole domain, the number of words in the specific article ranking on the page, and the number of times the exact keyword appears within that page.
10. GMB Everywhere
GMB Everywhere helps you analyze your competitors’ business profiles in Google.
In its free version, the extension shows all the categories businesses have selected in their Google Business Profile.
To check this, the most practical approach is to run a generic Google search for one of the services your business offers and look for the Local Pack, the Google map section where businesses offering that service appear. There, you will see orange labels showing the categories selected by each business.
As you can see, there is a wide range of SEO extensions available for Google Chrome. These are the 10 I use most often, although I also rely on others for different SEO-related tasks. The best approach is to try the ones that interest you and see whether they are genuinely useful in your day-to-day work.
