Instead of researching the keywords that your audience might use, Seed Keywords allows you to ask them for exactly what they would use..


By creating a scenario for your your audience – buying a jacket, looking for a book, finding a new restaurant – you can find the specific search terms that they’ll be looking for.

While this may not provide you with all of the statistics and search volumes, you can start to get an idea for what keywords show up the most.

And then you can cross-reference it with other tools like Google Keyword Planner to get search volumes.

24. WikiGrabber

WikiGrabber allows you to find those all-important broken Wikipedia Links and Citations that you can capitalise on.

Simply install the extension to your browser, and it’s ready to rock.

Let’s say you’re looking for bloggers to outreach to for backlinks and content sharing.

Where do lots of bloggers spend their time? Blog comments where they try to connect with their favorite authors.

Take a look at this post from Nomadic Matt. It’s an emotional post, and the kind of place where lots of people would go to offer comments.


If we head to the bottom, it’s got 39 comments from people.

This is the most popular travel blog right now, so most of these comments have links in them back to personal or travel blogs.

All you have to do is highlight the link and right-click. That’ll give you the option to Scrape Similar.


That will show you all of the hyperlinks in the blog comments of that page:


Export that into a Google Doc. And, now, you have a complete spreadsheet of bloggers and websites to outreach to:

The daily report shows a score that fluctuates between 0 and 10 like this:

You also get access to graphs like this one to get more insight.

A ‘high’ or ‘very high’ score indicates a big probability that your website’s rankings and search traffic could fluctuate.

48. Google Grump Detector

This is one of the coolest tools I use. It’s a little cheesy in the way it’s branded, but that doesn’t detract from how good the tool is.

Google Grump Detector (see my full Accuranker review) is like a weather forecaster for Google. It senses changes in Google’s ‘mood’ (algorithm) and gives you warning about the fluctuation in rankings.

Select your country and the device you’re interested in (mobile or desktop) to see whatever todays rating is:

google grump

It’ll then share with you the data for that specific database over the last month, so you can see the fluctuations.

google grump rating

If you’re not sure what levels of Grump there are, it also comes with a handy key:

google grump key

Worth checking once or twice a week, just to see what Google is up to right now.

SEO Browser Extensions

Not every SEO tool needs its own space to run.

These free SEO browser extensions can be used while you’re browsing the web which saves tons of time and money using other tools.

Remember that we selected the Keyword Surfer extension as one of our top 8 free SEO tools above which is not repeated in the list below.

49. SEO Quake by SEMRush

SEO Quake is a mini SEMRush plugged into your browser.

If you’re on the hunt for competitors, or find a site that you’d like to know more about, SEOQuake lets you check vital stats from your browser.


This is a tonne of data right at your fingertips, and it’s a nice tool to have around, so I’d recommend sticking it on to your extensions list!

50. MozBar

MozBar is one of the original SEO toolbars. And although the competition is getting bigger and better every day (see above) it’s still worth grabbing.


In Google Searches it gives you instant insights into the page, with a focus on Page and Domain Authority:

mozbar example

When you click on the link analysis tool, you can access every link that makes up their PA and DA for your own personal use:

mozbar link metrics

There is also a tonne of other metrics you can pay attention to as well, like Spam Score.

A great addition that works best in conjunction with other toolbars for best results but they are far from being the best backlink checker.

51. Check My Links

Check My Links is a really cool tool that allows you to check all of the links in your content – new and existing – to make sure that they’re valid.

That means you can easily find broken links, and repair them, to get almost instant SEO benefits. That’s a powerful free tool if I ever saw one.

check my links

Once installed it will crawl through a particular page and it will find the valid links and highlight them in green:

sej valid links

You’ll see all of the warning links in yellow; and all of the links you need to fix or change, in bright red:

invali dlinks

All of this is crawled in just a few seconds, and because it’s visual it makes a great aide to show potential new clients some of the issues with their site.

You can even use it for broken link building. Win win win!

52. No Follow

No Follow is a simple tool from IgorWare that highlights all of the No Follow links on a website.

no follow home

Simply download the extension and you’re ready to go. It’ll start to show you all of the no follow links on any page with a red box around them.

Just like this:

no follow global grasshopper

It’s not a tool that’s going to win any awards.

But, it can be really helpful in making sure you get the links you want, and aren’t hit by any nasty surprises right in the middle of your campaign.

Google’s Own Tools

Google’s tools are often overlooked by new SEOs. And, I get it – you want the shiny new third party tool that promises the earth.

But, some of the most established SEOs I know use these tools to form the backbone of their campaigns.

Google’s tools are free and you can extract valuable data in just a matter of seconds.

53. Google Analytics

Google Analytics shows you everything you need to know about your sites data.

It shows you the real-world results of every action you take on your site. How it impacts your traffic, how it increases your conversions, who it attracts to your site.

And, that’s just the tip of the iceberg.

The main reason I’d suggest you use Google Analytics is so you can track your progress and consistently strive to improve on it.

You can track how much of your traffic comes from different sources and dig even deeper to see where is bringing you the most traffic month on month.

But most importantly you can see which traffic converts:

Event Tracking Data

Now, it can be easy to get caught up in the Vanity Metrics (stuff that looks and sounds good but doesn’t really mean anything) that’s often provided by Google Analytics.

That’s why it’s important to use the tool to track results.

54. Google PageSpeed Tools

Your site speed is a huge ranking factor. The faster your page loads the more likely your site is to rank highly, and have a better customer experience to go with it.

Google PageSpeed Tools can help you track it.

Google PageSpeed Tools lets you see the speed of your site on Desktop and Mobile platforms.

Meaning you can create a much faster, more streamlined site, without negatively changing your search results.

​55. Google Keyword Planner

Google’s Keyword Planner still remains one the most popular keyword research tools.

And, for good reason – it’s still one of the most accurate free SEO tools available for search volume.

find keywords

And it’s not just great for search volume.

You can also find suggested keywords that relate to your terms and all of their metrics, too:

extra keywords

You can use the tool to research thousands of keywords straight from the horse’s mouth; as well as create plans that you can execute upon.

Take a look at my Google Keyword Planner tutorial to learn more.

56. Google Search Console

Google Search Console is a tool that every SEO should have as part of their arsenal.

You can manage a lot of the back of house for your site and find problems that are holding back your search progress.

For example, you can use the Crawl Errors tool to find problems:

google search console crawl errors

As well as being able to get access to a full breakdown of your backlink profile that is just as useful as some of the data you get with expensive tools:

google search console links report

It is also perfect for managing actions taken against your site, especially if you’ve been penalized for webspam or malware at any point in the past.

And don’t forget the most powerful feature of all!

Search Analytics.

That will allow you to see how your site is performing in Google right now.

You can track the total number of impressions your pages have in the SERPS along with the average ranking position and click-through rate data.

google search console performance

You can also find a list of keywords and you can filter by page to find out exactly which page is ranking for which keywords.

This is one of the most powerful hidden features of Google Search Console which makes it one of the best free SEO tools by far.
