Your GSC filters might be hiding your best keyword opportunities and you would never know
Posted by on April 4, 2026 at 11:55 amI want to share something I ran into yesterday that I suspect is affecting a lot of smaller sites.
I was doing a striking distance keyword analysis on one of my sites. It has about 224 total impressions over the last month. Not huge, but it is an active site with real content.
I filtered GSC for keywords between positions 5 and 15, set a minimum of 50 impressions, used a 28 day date window. Standard setup that most SEO guides recommend.
Result: zero keywords. Empty. Nothing.
My first thought was that something was broken. My second thought was that maybe the site just had no opportunities yet.
Both were wrong.
The problem was the thresholds themselves. 50 impressions minimum over 28 days sounds reasonable until you realize that a site with 224 total impressions across all keywords is never going to have individual keywords hitting that bar. The filter was designed for sites doing 10k plus impressions a month. I was using it on a site doing 224.
I dropped it to 10 impressions minimum and switched to a 90 day window. Suddenly I had a full list of keywords to work with.
The 90 day window matters more than people realize. Google Search Console averages out a lot of volatility over 90 days. A keyword that appeared 8 times in one month looks like noise. The same keyword appearing 24 times over 90 days looks like a real signal worth acting on.
Three things I now do differently for smaller sites
First, always use a 90 day window when the site has under 5k monthly impressions. 28 days is statistically useless at that scale.
Second, set impression minimums based on your actual traffic. A reasonable floor is roughly 5 percent of your monthly impression total per keyword. For a site with 500 impressions, that means minimum 25 not minimum 50 or 100.
Third, check position range not just position average. GSC position numbers are averages across all the queries that triggered your page. A keyword showing average position 12 might actually oscillate between position 8 and position 18. That range tells you a lot about whether the ranking is stable or volatile.
The broader point is that most GSC guides are written assuming sites with meaningful traffic. If you are in the early stages or working on a niche site that has not hit its stride yet, the default recommendations will make your data look emptier than it actually is.
Has anyone else run into this? Curious whether the 90 day window has made a difference for other small sites here.

Hey mate! Glad you figured it out, but all this is quite elementary. I don’t think you’ll find many people here who are analysing data that don’t understand these basic relationships.
If you just figured this out… Cool! Don’t think anyone’s finding this a problem though.

Ah! I see… You’ve built an SEO tool, and are looking for impressions and karma. Understood.
