Do you spend a lot of money on purchasing paid SEO tools?
If yes, you’re not alone. Many SEO agencies and marketers, business owners invest heavily in keyword research tools, rank trackers, and content optimization platforms—often paying hundreds of dollars each month.
But here’s the surprising truth: you don’t always need expensive tools to uncover valuable SEO insights. In fact, one of the most powerful keyword research hacks is hiding inside a free tool you already have access to that is “Google Search Console (GSC)“
With a single regex filter, you can find hundreds of hidden long-tail keywords your site is already ranking for but not fully optimized. These keywords often bring impressions but very few clicks—meaning you’re sitting on untapped traffic potential.
And the best part? It takes less than 2 minutes to find them.
Last week, I tried this trick:
- Found 250+ hidden keywords
- Updated my content in just 10 minutes
- Two pages jumped from page 2 → page 1 in 7 days
Here’s how you can do the same:
Step 1: Open Google Search Console
Log in to Google Search Console and select your website.
Step 2: Go to “Performance”
Click on the Performance tab in the left menu.
Step 3: Add a Query Filter
- Click + New Filter
- Choose Query → Custom (Regex)
- Paste this regex: ^(\w+\s){4,}\w+$
This will show you long-tail keywords (5+ words) that your site is already showing up for, but you haven’t optimized yet.
Step 4: How to Use this Asserts?
Now that you have the list of hidden keywords, here’s where the real magic happens…
Most people stop at just finding these queries—but if you know how to use them the right way, you can turn invisible impressions into page-1 rankings and a steady flow of new traffic.
-
Add the keywords naturally into your page content.
-
Use it in an H1 or H2 heading.
-
Update your meta title & description to include it.
-
Add 1–2 internal links with this keyword as anchor text.
Why This Works?
Google already knows your content is related to these keywords — that’s why your site is showing up for them.
By making small updates , you tell Google: “Yes, this page is highly relevant to this keyword.”
The result?
- Higher CTR
- Better rankings
- More traffic, without writing new content or building new backlinks.
