Why Are SEO Extensions for Chrome So Important?

A Little About Google Chrome

Most developers are already aware of the power Google Chrome brings to the table. It is the default web browser for all mobile devices running the Android operating system, and has versions available for Windows, Mac, iOS, and Linux.

It is currently the most popular web browser in the world, with 65% of the market share for all users across all devices. It is also the most used browser on tablets and smartphones.

Google has expanded the Chrome brand name to include its own operating system, as well as a host of other personal computing and home devices.

A Little About SEO

SEO (or search engine optimization) refers to the practice of “optimizing” a web page or piece of online content so that it naturally occurs higher on search engine results pages.

This can be accomplished by adding keywords that are easily searched and indexed, adding page and content formatting elements, and ensuring that content is added frequently on your website.

The practice of SEO is different from SEM (search engine marketing) in that it does not involve paid users. SEO focuses solely on organic traffic.

A Little About Chrome Extensions

Browser extensions are small add-ons to a web browser program. They can perform a number of functions related to user content and activity.

Chrome extensions for SEO can help users and developers with adjusting their content for the best possible optimization.

They can check things like keywords on a page, page structure, any dead links that would prevent desired actions, and where the page will rank on search sites.

Where Can I Get Google Chrome Extensions?

You can select and download Google Chrome extensions for SEO through the Google Chrome Extension store.

Best SEO Chrome Extensions

All browser extensions are free to download and install on Google Chrome. However, some may require the purchase of an additional service or subscription in order to function properly.

Each extension we’ve reviewed here has a direct link to let you download it from the Google Chrome Extension Store.

While it may seem counterintuitive, some pages should not be indexed for SEO. This requires some minor tweaks on the backend of a webpage to prevent a page from being crawled by search engines.

The NoFollow plugin checks your page to ensure that that piece of code has been added properly. It also checks any external sites that are backlinking to your page, so you can make adjustments accordingly.

Having functioning links across your website is not just a matter of providing quality service to your users. It also impacts the reliability of your content, and therefore its search engine rankings.

Pages that load quicker will perform better on searches. Use Chrome  extensions like these if you want to see how quickly your content will load, and what may bog down your site’s performance.

PageSpeed Insights by Google

PageSpeed Insights is another one of Google’s Webmaster Tools. This extension looks at your page’s load time.

Pages that take less time to load will perform better on traffic and conversions. This plugin will show how quickly your page loads, and what may be negatively impacting its load time so you can improve its performance.

PageSpeed Insights by Google is free for all users.


Lighthouse is an open-source extension for Chrome that tests your page’s speed, content quality, and overall performance.
