What is a chrome extension?

A Chrome extension is an add-on or plugin that can be added to the Chrome web browser, allowing users to perform specific tasks without leaving their browser. Some examples include checking grammar and analyzing traffic or metrics of a website.

Audience and Keyword Research Extensions

The first category of Chrome extensions can help you find or learn more about your potential audiences.

Many of these extensions only provide high-level information, so if you need to deep dive into keyword research, competitor, or backlink analysis, then use paid SEO tools.

Glimpse – Google Trends

The Glimpse extension for Google Chrome adds enhanced data to the default Google Trend experience, including monthly search volume, related trends, and longtail keywords.

It’s commonly used for researching keywords and finding business and e-commerce opportunities.

How to use

  • After installing the extension, you’ll need to sign up or log in (don’t worry, there is a free account option with 5 free searches a week).
  • You’ll be directed to Google Trends.
  • After following their onboarding instructions, enter a keyword or topic in the search bar.
  • In this example, I can see the upward trend for “ai copywriting,” but I can also see related trending topics such as “NFT generator” and “image upscaler.”
  • Scroll further down the report, and you’ll see other topics people search for.


SimilarWeb lets you view website traffic estimates and key analytics for any website, including site engagement rate, traffic ranking, and traffic source.

How to use

  • After installing the extension, visit a website you wish to analyze and click the extension button.
  • A panel is laid over the website showing metrics such as bounce rate, pages per visit, monthly visits, and average visit duration.
  • If you scroll down the panel, you’ll see traffic by country and traffic sources, including direct, search, referral, email, social, and display ads.
  • As the metrics are estimates, I recommend analyzing a few competitors to have comparative data, which you can include in a report.


This extension does exactly what it says in the name; it finds similar websites to those you’re currently browsing.

We use Ahrefs, and it proposes competing domains, but this is a free extension that shows similar sites and their monthly traffic; idea; if you’re conducting some preliminary or basic competitor research.

How to use

  • After installing the extension, visit your own website
  • Click the icon, and a window will show similar sites and their monthly visits.
  • Copy the sites and their traffic into a spreadsheet.
  • Repeat the process by visiting another website.

Semalt SEO Extension

The best feature within the free Semalt SEO extension allows you to see the most popular keywords and positions a website ranks in the search engines.

You can quickly look at your own or competitor’s websites and see any position changes over time. Still, you are better off using Frase Analytics or a rank-checking tool for comprehensive analysis.

How to use

  • After installing the extension, visit a website.
  • Click the extension button.
  • Scroll down to the “Rankings by keywords” report.
  • Select the Top 10 option.


Ubersuggest has a FREE SEO chrome extension that shows monthly organic traffic, domain authority, keyword search volume, position, and estimated visits per keyword.

The graph shows an upward trend in Frase’s traffic over the past 6 months, and the data is fairly accurate.

How to use

  • After installing the extension, visit a website
  • Then click the extension button, and the extension will lay the data over the website.
  • Use the vertical tabs to view keyword and backlink data.


The vidIQ Chrome extension provides tools to analyze your YouTube audience and competitors before creating new content.

Content extensions

The second category of Chrome extensions can help you create or optimize content.


The Grammarly Chrome extension helps users check their writing before publishing it online. It checks spelling, grammar, and plagiarism.

  • Use the setting button to change your writing language (I switch between American English for Frase and British English for my writing).
  • The toolbar will highlight recommended changes, remove redundancy, rephrase sentences, correct punctuation, and even propose complete sentences you should rewrite.
  • Click the proposed change, and Grammarly will update that content on your page.

How to use

  • You will be asked to register with Scribe before using the tool or extension; don’t worry, there’s a free plan option.

Technical and Performance Extensions

The third category of Chrome extensions can help you identify SEO issues, improve performance, or measure success.


The Mozbar Chrome extension provides Page Authority and Domain Authority for any keyword you search or web pages you visit, provided you register or log into Moz.

Additionally, MozBar will provide information about on-page elements such as the title, description, headings, links, and markup.

How to use

  • I searched for “SEO chrome extensions,” and you can see Moz data laid out on top of the top results.
  • Frase has a Domain Authority of 37, and these top pages have significantly higher authority.
  • Additionally, these top 3 results have many links, making it difficult for this page to rank high quickly.
  • I visited our AI content generator page to review the on-page elements using the Mozbar.
  • You can move the toolbar to the top or bottom of the page and then use the tab to review different elements.

Mangools SEO Extension

This is an extension to promote their free trial and subscribe to their service, so I’m not recommending this service; simply including it so this page is topically relevant.

How to use

  • Go to a web page after installing.
  • Click the icon on your browser.
  • I can get metrics such as Domain Authority and Page Authority for free with Mozbar.
  • No keyword information unless I subscribe.
  • No backlink data with registering.
  • But On-Page SEO information is provided.

But one tool from Mangools that I use regularly is their Google SERP Simulator, where you test and preview title tags and meta descriptions.

I entered a URL in this example, and the tool fetches the page title and description.

Now click the mobile option to see how your tags are displayed on a mobile browser.

Link Checker

This extension runs through links on the current pages and checks whether they work; it’s especially great for identifying broken links.

How to use

  • Install the plugin.
  • Visit a web page you wish to analyze.
  • Click the Link Checker button on your browser.
  • You can also check all the links on a web page by clicking the green, amber, and/or red sections in the pop-up window.

You can then click the link to find out where it is on the web page.

SEO Minion

SEO Minion is another Chrome extension to help with tasks such as on-page analysis, but it has a few other features the others don’t have, such as a Google location checker.

How to use

Click the web page you are analyzing after installing the extension, then click the SEO Minion icon in your browser.

This opens a window showing several features:

  • Analyze On-Page SEO
  • Highlight All Links
  • Check Broken Links
  • Hreflang Checker
  • SERP Preview
  • SERP Location Checker

My favorite feature is comparing search rankings for a search query in different countries with the SERP Location Checker (v/s) feature.

  • Change the dropdown options to the two countries you want to analyze

SEO Minion will show the SERP side by side so you can compare ranking positions.

There are many other great Chrome extensions for SEO, like the Ahrefs SEO toolbar, but we’ve tried to stick to ones with free plans.

These extensions should help you with keyword research, content creation, and SEO performance, but installing too many can slow down your browser.
