by Nedim Talovic · Updated 15 Aug 2021}}

SEO experts say that SEO is harder today because Google is not as stupid as it was years ago. If you remember, a back then you could build spammy links and easily outrank competitors so easy.

Today, you can’t do that because you will surely get penalized. In fact, some claim that SEO is dead now, but I wouldn’t go that far.

I think SEO is not dead, but things have changed. Today, as an SEO, you need to worry about time speed, responsivity, user experiences, links, and many other things.

Years ago, you only needed to make sure you got enough backlinks.

Anyway, nowadays you have much more tools that can make your life easier, so I’ve decided to explain 16 different SEO tools that you could use today to improve your business.

Let’s explore them!

#1 Hunter


Email outreach is very important if you’re doing link building.

Sometimes you find an awesome piece of content where you can get a link, but the problem is that you don’t know how to find an author’s email address.

Today, that’s not a problem anymore because there are various tools like this one that will do it for you.

One of the most popular tools is Hunter which is actually a web crawler. Hunter saves email addresses while crawling the web. It’s a commercial tool, but you can send 150 requests for free every month.

If Chrome extension is not enough for you, then you can use Hunter for Google Sheets, MailTracker, or API.

What I found really useful when I send email outreach requests is tracking who opened and clicked an email address because that way I can get some insights and understand better link building process.

#2 Keywords Everywhere

Keywords Everywhere - Keyword Tool

As an SEO, I can’t imagine my life without this extension because it lets me check search volume as fastest as possible.

The only thing I need to do is to send a query on Google and the results will come. Here’s how it looks.

Email marketing software: Search volume

Basically, I can see search volume, CPC, and competition data.

Now I don’t need to open AdWords Planner to check the search volume because the data is pulled directly from Google.

However, you can see the data in other places such as Google Analytics, Google Search Console, Majestic, Moz, and so on.

Seeing the search volume data in Google Search Console I found really useful because there I can see which terms do I rank for.

Here’s how it looks.

Google Search Console Search Volume

That way, I can see how many search volumes are there, so maybe I can focus on achieving top rankings for specific keywords by providing additional internal links, lowering bounce rate, and things like that.

#3 MozBar


Moz is one of the biggest SEO software companies, and their MozBar extension is surely a great choice for SEOs because there you can see the following metrics they invented:

  • Domain Authority
  • Page Authority
  • MozRank
  • MozTrust

These metrics will help you to estimate whether it’s hard to rank for the specific term or not.

Also, it allows you to spy your competitors and see what are their top performing pages, which pages have the most backlinks, and so on.

Simply said, everything is 1-click away. Please take a look at the following photo. These are top results for “Benefits of Google AdWords”.


Once I execute the query, I can see Page Authority of every page and basically, I can get an estimate how hard it’s to rank.

However, the extension isn’t only about checking the metrics because MozBar gives you on-page content suggestions, optimization factors, and so on.

#4 Grammarly

Gammarly There’s no SEO without good content and there’s no good content without grammatically correct sentences.

Lots of marketers who are not English native speakers are struggling with content marketing because they don’t know how to write grammatically correct sentences.

However, that’s not the problem now because there are tools such as Grammarly which will help you with your content.

I’m not a native English speaker and after I started writing the content, I was making mistakes that I haven’t even thought about, but now, the number of errors has reduced dramatically.

What’s more, Grammarly free version works great, but surely, if you want to write the most advanced sentences you should consider buying a subscription.

Grammarly scans your text for proper use of more than 250 advanced grammar rules, contextual spelling checker, and vocabulary enhancement.

#5 SEOquake


Knowing that over 375,000 SEOs use this extension means something. SEOquake claims that they are a powerful SEO toolbox for your browser and I couldn’t agree more.

SEOquake gives you lots of metrics and here are the most important:

  • Alexa Rank
  • Google Index
  • Bing Index
  • SEMrush rank

SeoQuake Toolbar

So, within a click, you can see how many pages you got indexed on Google, what’s your Alexa ranking, and so on.

Furthermore, you can do On-Page SEO audit very fast by clicking on Diagnosis.

There, you can see if your URL, title, and description length are optimal, and also you can check if some site has implemented markup, Twitter Card, The Open Graph, and many other important things.

Finally, I’d like to say that you can do keyword destiny of every page. If you don’t know what does it mean, here’s an explanation.

Keyword density lets you check if you use some keyword too many times. In other words, it tells you if the page you’re optimizing is actually overt-optimized.

#6 SeoStack Keyword Tool


I know that you probably use tools like and AdWords Keyword Planner for finding new keywords.

But, have you ever thought that you can use a Chrome extension to find long-tail keywords?

Well, that’s exactly what SeoStack Keywordtool extension does for you, and here’s the reason why finding long-tail keywords is important.

Long-Tail Keywords

Long-tail keywords have a higher probability of conversion and lower competition. For example, when someone searches for “shoes” we don’t know the exact intent.

Maybe he’s just interested in getting informed about the latest trends, or maybe he’s looking to buy new shoes.

On the other side, when he searches for “red Nike men running shoes” we’re pretty sure that his intent is commercial.

He knows what he’s looking for and that’s the reason of high probability of conversion.

What’s more, the more words in the phrase you have, the less search volume you’ll get, so simply said, fewer people are interested in ranking for those keywords.

Now, let’s see how to find long-tail keywords by using this extension.

Firstly, open the extension and enter what you’re searching for. For this example, I’ll enter email marketing.

 SeoStack: Enter Keyword

If you look carefully, you can see that besides Google there are other sources as well (YouTube, Bing, Yahoo, Amazon, eBay), and also different regions and languages.

Once you click on Start, hundreds of keywords will be generated, and here are some of them.

SeoStack Results

That’s it. I hope you realized how effective this tool is.

#7 Nimbus


Personally, I hate blog posts without images because it’s hard to read them.

I think that every successful blogger should add lots of screenshots and images to its blog posts, so I thought that you might be interested in Nimbus.

Nimbus is a completely free tool that lets you make screenshots in three clicks. You can even draw arrows, blur photos, add text, or do whatever you wish.

In other words, you don’t need to open Photoshop for getting top images.

Nimbus Options

There are few ways of capturing screenshots:

  • Visible part of page
  • Capture fragment
  • Selected area
  • Selected & Scroll
  • Entire page
  • Browser window
  • Blank Screen
  • Record Video
  • Android Version

If you were reading the list carefully, you could see that it’s even possible to record a video which is surely great for showcases.

#8 Alexa Traffic Rank


Alexa is an Amazon company which provide useful insights about your and your competitor's’ site.

They built one of the most popular website metrics called Alexa Ranking which tells you how popular a website is.

This is a good way to see a fast overview of someone’s site and check if it’s popular or not.

Next, you can find similar websites which might be useful if you would like to find a similar site to those who linked your site.

Now, here’s what I found the most useful feature.

Alexa Overview

Basically, you can check how fast some website is and compare it to others.

Okay, I know that’s available on Pingdom too, but here you don’t need to wait a couple of seconds.

The benchmark is available immediately.

#9 SimilarWeb

SimilarWeb Overview

Would you like to know how many visitors your top competitor has? You probably would. The truth is that you spying competitors has never been easier thankfully to tools such as SimilarWeb.

There, you can see the number of estimated visits, time on site, page views, bounce rate, and many other options.

For example, I know that HubSpot has a total of 21.5M visits and I know that they got a really low bounce rate which is awesome.

What’s great with SimilarWeb is that they are the most accurate tool in the world. I don’t know anything about their methodology and collecting the data, but I know they are extremely accurate.

In fact, I’ve been comparing with friends whose number of visitors I don’t exactly know, and guess what. SimilarWeb told me the exact numbers.

What’s cool with this extension is that you can also see which channels are the most important for some site.

HubSpot’s most important channel is organic channel because 36.40% of their visitors come from search engine.

#10 Mobile/Responsive Web Design Tester

Mobile responsive web design tester

You know that Google has rolled out the mobile-friendly update on April 21, 2015.

Since that, lots of sites became responsive, but however, you need to test your site on different devices if you’d like to provide an outstanding user experience.

Buying lots of different mobile devices would be ridiculous. Instead, you only have to install the Mobile/Responsive Web Design Tester extension which does the job for you.

Once you install it, you’ll need to pick a device that you’re interested in testing:

  • iPhone 6
  • iPhone 5
  • iPhone 4
  • Galaxy S6
  • Xperia Z3
  • Lumia 920

There are also lots of different tables too. You don’t need to worry if there’s no some mobile device. If the site works fine on iPhone 6 it will surely work on iPhone 7, for example.

#11 WordCount

Word Count

Lots of marketers say that you should write in-depth articles because Google tends to rank them higher.

Thankfully to this extensions, you can select the text and you can count the number of words within a click.

This is also good for checking how many words your competitors write. In fact, there was a research from Backlinko which suggests that top ranked pages really have longer content.

Here’s how it looks.

Content Total Words

According to the photo above, you should write at least 2000 words per article if you would like to rank high.

Of course, there are many factors that have the impact on ranking, but generally, the longer content you have, the better ranking you achieve.

I think that the reason why those sites rank higher is that when you have a good in-depth article, you’ll collect more backlinks and in the end of the day, you’ll rank higher.

Just think about the difference between the following two articles:

  • 37 Mistakes Email Marketers Must Avoid
  • 6 Mistakes Email Marketers Must Avoid

Which article is most useful to users and which one would get more backlinks?

The first, of course.

#12 Majestic Backlink Analyzer

Majestic home

Majestic is a popular paid service which lets you check how many backlinks do you have, but it also lets you track how successful your or yours competitor’s SEO is.

For example, Majestic has invented metrics such as Citation flow and Trust flow which tells you a lot about some site.

Here’s what you can learn about someone’s site.


Basically, you can see the number of external backlinks and the number of referring domains which is still one of the most important Google ranking factors.

Next, you can see Majestic metrics like Trust Flow and Citation Flow which is pretty good for spying the quality of competitor’s backlinks estimating how hard it might be for outranking someone.

Also, there are two charts which give you a fast overview of someone’s SEO.

#13 GetPocket


While you browse the Internet you’ll undoubtedly find interesting stories that you’d like to include in your blog posts.

In fact, handling all stories and information may be hard, but using an app like Pocket will make everything easier a lot because as you can see, it says “whenever you find something you want to view later, put it in Pocket”.

Another interesting feature is that there you can find the best of the web of any topic which might be great for adding new references on your blog posts.

Lots of people use apps like BuzzSumo when they want to see what’s trending on social networks, but you can use - GetPocket.

In other words, Pocket will help you to determine which content is shareable and which is not shareable so you need to avoid that unless it’s not SEO valuable.


I hope you enjoyed reading about these extensions because they are lifesavers for SEOs. I’m sure you won't’ use all of them because you’ll lose focus if you do that, but however, you should pick a few of them.

Personally, I picked the following extensions:

  • Keywords Everywhere
  • MozBar
  • Grammarly
  • Nimbus
  • SimilarWeb

Here’s why. Keywords Everywhere gives me the search volume everytime I enter the query on Google, so I don’t need to open Google Ads Keyword Planner.

Next, I use MozBar because Moz has invented the best SEO metrics ever. I respect metrics from other companies, but they are not at this level, still.

Writing articles without worrying about the grammar is important to me, so that’s the reason I picked using Grammarly because they are the most accurate grammar checker tool.

Creating screenshots is an important part of my content writing, so Nimbus helps a lot because thankfully to it, I don’t need to open Adobe Photoshop and waste my time.

Finally, SimilarWeb is good because it lets me spy my competitors and how many visits they got in the last month.
