Extensions and plugins are essential for everyday developers and administrators who work with a site’s organic SEO.

Discover the selection of the best toolbars, browser extensions and plugins for website analysis and link profile analysis.

With the right SEO tools at your fingertips on your browser, it is possible to increase efficiency and organize your SEO methods.

  1. Firebug

Firebug is closer to a development console for Firefox than a plugin of natural referencing in the strict sense of the term. This console allows you to analyze Web site elements based on source code, redirects and load time.

After locating some HTML elements, it is possible to work directly in the browser. CSS rules can be adapted and changes are saved temporarily in the browser application.

2. Web Developer

The equivalent of Chrome for Firebug is “Web Developer”, an extension of Google. This plugin for natural referencing has a wider range of functionality and allows web developers to modify all the spaces of a website.

Just one click to activate or deactivate multiple functions of the page. This includes caching, JavaScript, Meta redirects, or color indications.

This plugin also allows you to view cookies that can be edited or deleted. With the CSS tools, it is possible to rework each style sheet of the website.

3. Linkparser

This little tool is dedicated to the analysis of the link structure. This plugin distinguishes up to nine different link types (e.g. internal/external, follow / no follow). The number of links is displayed in the Browser Quick Preview.

The type of links displayed by Linkparser is determined by the user. By clicking on the logo of the browser, the links in question are highlighted and the user determines their classification.

4. MozBar

The analysis tool of Moz.com is known and appreciated by the majority of experts in natural referencing, and it is one of the most used plugins. The Moz toolbar automatically displays different metrics for Offpage analysis when a page is viewed.

Among these are Moz-Rank (an indicator that evaluates the popularity of a website), Page-Authority, Domain-Authority as well as the number of backlinks (also called back link). Next to the toolbar is the Overlay, which provides more information about the elements of the page and its attributes (URL, Title, Meta-Description, H1, etc.).

This makes it possible to carry out an On page analysis and its optimization. In addition to the toolbar and Overlay, Moz displays relevant data about links under the search results as well.

5. SEOquake

The SEOquake toolbar offers features similar to MozBar, and it is a very popular plugin in the field of SEO. This tool delivers all metrics pertaining to the pages of a site (for example PageRank) for all available search engines. The link profile, title, meta-description and Meta keywords are available with one click for the user. There are multiple customization options and many features.

6. Majestic SEO Browser-Plug-in

The Majestic SEO browser plugin is primarily dedicated to back links. Important indicators such as the number of backlinks, their value or confidence indices are also taken into account.

To do this, the tool uses a large database of back links. This is especially useful for users because the main values can be displayed with a single click and presented in a clear way.

7. PageSpeed Insights

This browser tool allows you to receive tips and tricks to optimize the user experience by entering the URL of a site. This plugin also makes it possible to speed up the loading time of the pages, which improves the SEO. PageSpeeds optimization works best with the Google PageSpeeds tool.

It is notably with the growth of mobile commerce and the growing importance of load time on mobile web pages that this tool becomes a must in the middle for any website administrator. There is no browser plugin available, but the on-line tool allows to analyze a page directly on the browser.

8. Seerobots

The SEO Seerobots extension examines a website using the robot Meta tags. If a website is not yet under construction, it is better that it is not yet indexed by Google.

It is preferable that a site is indexed when it is completed, and that all the general conditions are met in an adequate manner. This is why the meta tag “robots” intervenes with the attribute “no index”, that is to say, ” no-follow”.

Using these tags, the search engine recognizes that the website in question should not be indexed. If you want to index the page later, the tool helps to keep a good overview by marking the tags with a color.
