CanIRank
Very cool.

CanIRank isn’t just for sizing up the first-page competition.

- Google’s Mobile-Friendly Test
Get your site ready for Google’s Mobile-first Indexing.
You might have heard that Google recently made a big change to its algorithm.
(This change is officially called “Mobile-First Indexing”.)
The bottom line is this:
If your site isn’t optimized for mobile devices, you’re in big trouble.
Fortunately, you don’t need a full-time developer to make your site mobile-friendly. All you need to do is run your site through the Mobile-Friendly Test tool.
And it tells you whether or not Google considers your site mobile-friendly.
Google’s mobile friendly test

This feature shows you how you can improve your site’s code. That way, Google’s mobile crawler can find and index all of the resources on your site.
Mobile-Friendly Test – Issues
- Seed Keywords
Find completely fresh keyword ideas.
Most keyword research tools work the exact same way:
Enter a seed keyword into the tool.
Get a list of closely-related terms.
The problem with this approach is this:
Everyone types the same seed keywords into these tools.
Well, Seed Keywords takes a completely different approach.
Instead of pulling seed keywords out of thin air, you ask your customers how they’d search for you online.
SeedKeywords – Scenario
Then, type those seed keywords into your favorite keyword research tool.
Best Feature: “Submit Query”
Once the results come in, you can use SeedKeywords to do a Google search for the keywords that people gave you.
That way you can quickly scan the search results… and see how competitive those keywords are.

This free SEO tool does one simple thing:
It bubbles up topics that are just starting to trend.

The tool currently has about 2k topics in its database. And they’re adding more every week.
Best Feature: Categories
Categories let you drill down to a specific topic category that’s important to your business.

In my experience, X vs. Y keywords are super untapped.
Sure, they may not get as many searches as traditional keywords. But they’re SUPER targeted and high-converting.
And to my knowledge Ubersuggest is the only tool that specifically bubbles up X vs. Y keywords.
- BROWSEO

As it turns out, search engines see your site VERY differently than you do.
And BROWSEO gives you the type of x-ray vision that search engines have.

OK, OK. Google Analytics isn’t really an SEO tool.

I’m talking about data like:
Organic traffic
Bounce rate
Traffic sources
Time on site
Page speed
Google Analytics
Best Feature: Google Analytics and Google Search Console Integration
Google Analytics is super powerful on its own.
But when you combine it with the Google Search Console?
It’s even MORE powerful.
Linking your GSC account with GA hooks you up with helpful info, like the keywords people use to find your site, your organic CTR, and more cool stuff.
Google Analytics – Google Search Console

KWFinder

KWFinder – LPS
- People Also Ask
This free tool pulls questions that appear in the “People Also Ask” section of Google’s search results.
Usetopic – People Also Ask
My only gripe with the tool is that it takes a while for the results to load. But I understand that’s because it has to actually run the search and grab questions from the PAA box. Which takes a while.
Overall, a very cool tool for finding question keywords.
Best Feature: Related Questions
People Also Ask shows you questions that you’d usually have to get by manually clicking on the PAA box in the SERPs.
For example, one of the questions the tool showed me was “What is a good keyword?”. And I also got a handful of questions that were closely related to the original question.
