SEOs love Chrome Extensions.

And no wonder. Their ability to augment what you are already doing in your browser can save hundreds of hours.

The only problem is there are so many to choose from!

So we scoured the Google Chrome Web Store for the best extensions that:

  1. Cover the essential tasks a modern SEO needs;
  2. Perform said tasks quickly;
  3. Have a minimum of overlap in features

And good news!

It turns out you can do the essential SEO tasks with just five extensions. And five is better than fifty-five for at least two reasons:

  1. Fewer icons in your toolbar mean fewer things to be distracted by;
  2. Fewer extensions mean less strain on your computer, too

With that out the way, it's time to share the best SEO extensions for Google Chrome.

The Essential Five

These are the top extensions for carrying out popular SEO related tasks.

Install these five, and you are good to go:

  1. Detailed SEO Extension
  2. Keyword Surfer
  3. Wordtracker Scout
  4. Hunter - Find email addresses in seconds
  5. SimilarWeb - Traffic Rank & Website Analysis

These Chrome extensions cover the tasks that matter most for modern SEOs. And just as importantly, they are enjoyable to use.

Let's take a closer look at them.

Starting with:

The Best Chrome Extension for On-Page SEO Analysis

On-page SEO is the practice of helping search engines and humans better understand your content.

Researching how the top-ranking pages have dialed-in their on-page SEO can provide clues for success, and checking your own pages can highlight what you could do better.

Google Chrome extensions are ideal for quickly analyzing the on-page SEO elements right in your browser.

You can get SEO insights into what has been done well, what can be done better, and what is missing entirely, all with minimal effort.

Of course, there are dozens of Chrome extensions for extracting and researching the myriad on-page SEO factors.

But thankfully, you only need one:

Detailed SEO Extension

This Chrome extension delivers fast page-level insights.

With one click, the Detailed SEO Extension reveals the most critical on-page data you can action right away.

Here are a few cool things you can do in a snap:

  • Quickly view the page-level metadata including the canonical tag and X-Robots tag;
  • Another click reveals all the heading tags, indented accordingly, for ease of understanding;
  • Jump to the “Links” tab, and you will see a total count of links both internal and external and how many are unique (with options to export to CSV, of course);
  • You can even view the Schema for the page, and snoop on the social metatags;
  • It's a handy “launchpad” too, with quick links to fire up other popular SEO services —like Ahrefs, Archive.org, Moz, SimilarWeb, and so on— for the website you are currently viewing

While there are other options available in the Chrome Web Store, you only need one.

And Detailed SEO Extension is the Apple of the on-page SEO category.

As this tweet puts it:

Loving this new SEO Chrome extension from @ViperChill. Every other one I've tried has bloat, looks horrible, or has a paywall. This is simple, fast, and lightweight! 👏 [source]

There's a lot to be said for speed, especially with Chrome extensions. You are checking web pages on-the-fly after all.

And the quicker we can understand what we are looking at, the sooner we can act on that information.

It's difficult to explain, but the Detailed SEO Extension has a cognitive fluency edge over the competition.

And if you want to dig deeper, there are shortcuts to open up your favorite SEO tool for more in-depth analysis.

This is smart because, for deep SEO work, specialist tools still reign supreme.

Whereas Chrome extensions are best for doing quick tasks as you go.

Speaking of which:

The Best SEO Extensions for Keyword Research

Whether you are looking for new content ideas, or to improve your on-page SEO with new words and phrases, “there's a Chrome extension for that.”

Having a sidekick in your browser opens up some exciting possibilities for keyword research.

For example, while searching Google, you can get search volume metrics fed back in real-time without lifting a finger.

And while searching for one keyword, you can see related keywords with their respective search volumes, too.

But wait, there's more!

How about a quick graph to show the number of backlinks for each web page ranking, correlated against its position, for the keyword you are researching?

That's quite a mouthful.

But ask, and you shall receive:

Keyword Surfer

Keyword Surfer is a free extension that augments Google’s search engine results pages (SERP) with additional data.

This gives you a quick at-a-glance way to see search volume, related keywords, and basic comparative metrics about each ranking domain.

And all without leaving the search results page.

Here's what Keyword Surfer can show:

  • The search volume of your keyword (both globally and in the country of your choice);
  • A list of similar keywords with their respective search volumes, along with a “similarity” score which tells you what percentage of the top 20 results for each keyword overlap with the current search;
  • A list of related keywords and their search volume, too;
  • A “backlinks and visibility correlations” graph showing the number of “quality backlinks per domain” (I checked, and they explain: “Surfer crawls only pages that rank in top 100 for any query. We have decided to show only links from websites that have any visibility”);
  • You also get a second graph that shows the estimated traffic each domain receives

All of this data is reported live while you search in Google.

Handy!

I like Keyword Surfer because it is free, fast, and insightful without being overwhelming.

And now for something different:

Wordtracker Scout

Yes. Another keyword research extension.

This Chrome extension is a lesser-known gem that provides a unique way to view the primary keywords used on any web page in your browser.

For example, visit a competitor's page that is ranking well, and fire up the Scout.

After a few seconds, the wonderfully simple interface will reveal the most important keywords on that page.

And Wordtracker Scout has a refreshing way of presenting its data, too, which further helps to earn its place on this best-of list.

Here's what I mean:

Wordtracker Scout creates a word cloud from the web page to visually show you the most popular keywords on the page, along with their relative importance to one another.

Which is cool. But it gets better...

This extension shows the relative search volume for each keyword, too.

All within a single window.

This is a smart way to show three handy metrics in one at-a-glance view.

Here's how this works:

  1. The words that make up the cloud are the most frequently repeated words on the page;
  2. The size of the individual words reflect how often they are repeated on the page in relation to the other words;
  3. The darker the color of the word, the more search volume it receives

You can also click on any word in the cloud to reveal its search volume, the number of times the word is repeated, and how relevant overall to the page it is.

You can even filter the list by your preferred “number of keywords” length, from one to five words (to drill down to the long tail.)

Helpful!

Use this Google Chrome extension to uncover keyword ideas from your competitor's pages, and use it to examine your own content to confirm the primary words Scout reports are indeed the ones you intended!

Lastly, it is worth mentioning that Wordtracker uses its own database of “hundreds of millions of keywords” along with their database of “billions of real searches by real people” when reporting their numbers.

This makes it an excellent complement to the usual tools which predominantly rely on Google's database.

OK, let's change tracks...

A Solid Chrome Extension to Assist Outreach

One vital job for SEO professionals is performing outreach duties to build relationships for potential linking opportunities.

After all, the best links are usually found through good relationships.

This is an area where the human touch is necessary. Outreach is a time-intensive endeavor you can not scale easily.

Indeed, scaling tends to erode the human touch that is so essential for lasting success.

Still. Anything which can make the manual process easier is worth adding to your toolbar.

With that mind, you will be happy to know there are Chrome extensions that specialize in outreach management.

For our best-of list, we will keep things simple and look at a Chrome extension whose sole purpose is to help find the crucial contact details behind the website you are interested in exploring a relationship with.

Hunter

Hunter offers a simple yet immensely popular service: to help you find the contact information behind a website.

And with the Chrome extension installed, you get the contact details right in the browser.

Hunter is accurate, fast, and does exactly what it says on the tin.

Their slogan is “connect with anyone.” And with a vast database behind them, they do an excellent job of delivering on their promise.

They have a free plan which grants you 50 credits (searches) per month.

Using Hunter, you can dig up email addresses, names, job titles, social networks, and phone numbers.

For each contact found, you can check the sources for the data and even see if the email address is verified or not (with the option to quickly test it on the spot.)

As you browse the web for potential relationships, Hunter is all you need to begin your outreach efforts. After all, a relationship starts when one person contacts another.

Best Extension for Competitor Analysis

It would be wonderful to see traffic metrics for competitor websites, along with their engagement rates and traffic sources, etc.

Sadly —or thankfully, depending on which side of the fence you stand— this is difficult to do.

There are a few services that provide this kind of market intelligence. But their accuracy is debatable and best taken with a pinch of salt.

Still, it is useful to analyze traffic data where you can find it. And use it to compare the relative popularity of one website to another.

Enter...

SimilarWeb

The SimilarWeb extension aims to give you website traffic intelligence, including engagement metrics and traffic sources.

Once activated, a handy graph shows the traffic trends for the past six months.

At-a-glance you can see:

  • Total monthly visits;
  • Bounce rate;
  • Pages per visit;
  • The average visit duration;
  • Traffic sources by Country;
  • Traffic sources by medium (percentages split across search, direct traffic, referrals, social, email, and display ads)

As I said above, I would take these figures with a pinch of salt.

Furthermore, SimilarWeb will not have data on every website, either.

But you can still use them for rough comparative insights into how one website is performing compared to another and look at traffic trends.

It is also a simple tool to use.

One-click is all it takes to see some potentially revealing data.

Special Mentions for Other Top Chrome Extensions

In truth, there are plenty of other popular extensions that have a large following.

These are ubiquitous in any best-of list.

So, let's take a quick look at a few:

  1. SEOquake
  2. Mozbar
  3. Redirect Path
  4. Keywords Everywhere
  5. LinkMiner
  6. SerpWorx

SEOquake

SEOquake is a monster add-on. It is an “everything but the kitchen sink” extension made by SEMrush.

As you would expect, SEOquake is well-maintained. And highly configurable.

While you do not have to connect this extension to a SEMrush account, it is worth doing so to unlock more data. And you can even use a free account.

Mozbar

Mozbar is another heavyweight SEO extension.

You can hook up your Moz account (free or paid) to see metrics about the page you are browsing, and also examine data right from the SERPs.

Along with SEOquake, these two heavyweights are all about providing a TON of information for both on- and off-page SEO.

And therein lies a problem.

Are these too complex for most people’s needs?

They are not the quickest or easiest extensions to use.

But if you want the Swiss Army Knife approach, then go for it. Just keep in mind the risk is they can become more of a distraction than an aid.

What you gain in density, you lose in clarity.

Redirect Path

Redirect Path is the opposite of the Swiss Army Knife. It lives to perform one task only, and it delivers it perfectly: to give you a window into what is happening in the HTTP Header and report any redirect chains.

Checking for HTTP Status Codes and redirect chains forms part of any respectful technical audit.

Redirect Path is highly recommended.

Keywords Everywhere

Keywords Everywhere is a freemium Chrome extension and a popular choice for keyword research. However, it is somewhat limited in the free version.

If you don't mind paying —and it’s not expensive— the full version makes for an excellent keyword research tool.

Keywords Everywhere display search volume, CPC, and competition data from 15+ websites including Google, Search Console, YouTube, Amazon, and so on.

Well worth exploring further.

LinkMiner

LinkMiner is a broken link checker.

But in all honesty, I could not find a broken link checker that I liked.

LinkMiner came close, though.

What I like about LinkMiner:

  • At-a-glance total count of links shown directly in the toolbar;
  • Just one click to reveal the total number of broken links, and it instantly highlights every good link green and every bad link red;
  • Can be hooked up with Ahrefs, Majestic, and Moz to show metrics about the links

However, I am not confident this extension will receive any further updates. And while it worked for me, some are reporting problems.

As an aside, I found the homepage for the developer (pointblankseo.com) now redirects to backlinko.com, which only adds to my doubts about its future!

Beyond LinkMiner, the other popular link checkers are ugly, require more steps to work, and still have bugs.

SerpWorx

This Chrome extension provides you with the “best SEO metrics behind the sites in the search results & on any site.”

SerpWorx fetches real-time data from all the popular SEO service providers, including Majestic SEO, Moz, Ahrefs, and SEMrush.

This data does not come free, however.

SerpWorx is a premium SEO tool.

Action Steps

Google Chrome extensions save you time and make life easier.

You just need to take action and use them!

Here's what to do now:

If you don't know where to start, just go and add the following five extensions.

If you have no extensions, these will cover the basics with minimal overlap.

They are the best of their type:

  1. Detailed SEO Extension
  2. Keyword Surfer
  3. Wordtracker Scout
  4. Hunter — Find email addresses in seconds
  5. SimilarWeb — Traffic Rank & Website Analysis

Remember that extensions use your system's resources. That means there is a cost to adding them. This is why I recommend picking wisely. One extension for each main category. Two at a push.

Conclusion

The best Google Chrome extensions turn the humble web browser into a powerful SEO analysis tool.

And you can't go wrong with any of the ones listed above.

Just be sure to exercise control and install the fewest extensions you need. Your brain —and the “brain” in your computer— will thank you for it.

And just think:

The thing that stands between where you are and where you want to be could be just a click away with the right Chome extension.

Enjoy!
