On page SEO: 5 essential free SEO Chrome extensions

Extension SEO chrome


In the SEO world, there is a plethora of plugins and extensions for browsers, especially for Google Chrome and Firefox. Free or paid, these extensions allow you to easily (and quickly) view or collect a panel of useful information in the analysis of a page or a domain, but not only …

In this article, we will go over a selection of Chrome extensions for On Page SEO analysis. The objective here is not to list exhaustively all the free extensions available on the Chrome Web Store but to present those that we actually use, those that have proven to be essential to our daily SEO consultants.

SEO Meta in 1 click: the main SEO information, in 1 click

SEO Meta in 1 click

In its first tab, SEO Meta in 1 click allows you to quickly visualize the main SEO metas, like :

But also :

  • Number of titles hn (h1, h2, h3 …)
  • Number of images
  • Number of outgoing links
  • And various “macro” information on links, metas, scripts …

Summary SEO meta

It is mainly for its very practical “Summary” functionality that we like this extension. SEO Meta in 1 click also displays all the hn titles in its “Headers” tab. The “images” tab displays the urls, the contents of the alt tags and the titles of the images. In the “Links” tab, you will find a summary of the links on the page, as well as a list of all the links:

Finally, the social tab allows you to find the content of OG tags, Twitter card etc.

SEO Meta in 1 click is therefore a practical and relatively complete tool that allows you to quickly know the main “on page” elements used for natural referencing.

In the same category, we also find the Open SEO Stats extension which offers much the same thing with some additional data such as traffic estimates (not always functional), information on the site (domain, location, IP, presence of the robots.txt, sitemap…), and some less data (images, hn structure).

Web Developer: the Chrome extension designed for developers, downloaded by SEOs

webdevlopper extension chrome

Arguably one of the handiest extensions for Google Chrome on this list. Web Developer is full of features and it would surely take an entire article to detail all the possibilities that this tool offers. We will focus here only on the main functions.

The Disable tab:

disable

As its name suggests, this tab of the Web Developper extension allows you to disable certain elements on a page. This can be practical in navigation in general but in terms of SEO, we particularly appreciate the option “Disable JavaScript” which allows you to navigate on a page / site without JS and to see how the site behaves. Typically, see if all the content is still accessible without Javascript.

The CSS tab:

CSS Toolbar

In the same logic as for the “Disable” tab, we also use the CSS part to deactivate all the “Disable All Styles” styles, and see how the page looks without CSS. This very often makes it possible to detect points of improvement.

The Information tab:

information toolbar

In the “Information” tab, we mainly use two functions: the “View Document Outline” function and the “Display Link Details” function.
“View Document Outline” only displays the hn titles, which allows you to see at a glance whether the page has structural problems (missing title, title break, empty tag, etc.) and also the semantic relevance of these titles :

The “Display Link Details” function makes it possible to display the urls of all the links present on a page, which can be practical, if only to quickly find out all the pages targeted by the links.

Redirect Path: status code and (paths) of redirects

Chrome Redirect Path Extension

A simple and efficient SEO tool allowing to check and verify the HTTP headers (response code 200, 404, 500 etc.) of a url and above all, the potential redirects. Redirect Path indeed displays all the redirects and their type (302, 301, 307, 308…) which makes it possible to test or verify particular pages, to detect the chains of redirects and to know their details. The Redirect Path plugin also mentions the presence of redirect loops. The extension finally displays various information extracted from the header and others (content type, server, cache etc.):

Conclusion on (free) extensions for on-page SEO analysis on Google Chrome

As explained at the beginning of the article, there are a large number of Chrome extensions for on-page SEO analysis. We have listed above only the most frequently used extensions to quickly audit a web page. Extensions dedicated to Lighthouse-type performance analysis have been excluded from this listing in the sense that they go a little outside the strict framework of On-Page analysis. It’s more about template and server optimization than the page itself.

In addition, it is important to remember that these extensions are certainly very practical but that they are far from being sufficient on their own. They allow you to observe specific points and highlight avenues for optimization, but nothing replaces a real SEO technical audit. The use of crawlers in particular (like Screaming Frog to name just one) remains essential to have a complete vision of the factors blocking the natural referencing of a website.
