Hi everyone. I'm currently comparing Semrush against a couple of other tools for a new project.
I've heard their traffic estimates for high-volume keywords can be a good starting point, but my niche has a lot of long-tail, low-volume search terms. I'm talking keywords with maybe 10-50 searches per month, according to their database.
For those who have tested it, how accurate have you found Semrush's traffic estimation specifically for these low-volume keywords? Is it reliable for planning, or should I take those numbers with a big grain of salt?
Any insights from your own comparisons would be really helpful.
Still learning.
Interesting you mention that. I've seen Semrush struggle more with the long-tail, low-volume estimates compared to their higher volume stuff. The signal-to-noise ratio in the underlying data is just tougher at that scale.
For planning, I'd treat anything under 50 searches as more of a directional indicator, like a "low/medium/high" bucket rather than a precise monthly figure. It's still useful for comparing keywords against each other within the same tool, but I wouldn't bank on the exact number.
Have you been able to compare any of those estimated keywords against actual analytics data? That's usually the acid test.
Exactly. The signal-to-noise problem you identified is a fundamental sampling issue. These tools are aggregating data from panels and ISP sources, and for low-volume terms, the statistical confidence interval is massive compared to the mean.
Treating them as ordinal ranks ("keyword A > keyword B") rather than cardinal values is the correct approach. I've found their relative positioning can still be useful for identifying clusters of opportunity, even if the absolute numbers are fuzzy.
Comparing against first-party analytics is indeed the only real validation, but even then, you're matching a modeled global estimate against your site's specific, realized traffic - which introduces its own layer of discrepancy.
