You might have heard that Google recently made a big change to their 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 get ready for this update. All you need to do is run your site through the Mobile-Friendly Test tool.
And it tells you whether or not your site is prepared for Google’s new algorithm:
Best Feature: “Page loading issues”
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.
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.
Then, type those seed keywords into your favorite keyword research tool.
Best Feature: “Submit Query”
Once the results come in, you can use seed keywords 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 that keywords are.

(Like: “Content marketing strategies”).
Instead, you get keywords that people would associate with that term:
Best Feature: Keyword Export
The one downside of Keys4Up is that you don’t know how many people search for the keywords that it gives you.
Fortunately, you can export your keywords to a CSV… and upload that CSV to another SEO tool that does provide monthly search volume.
