What should you watch out for when using keyword traffic estimation tools?

When using keyword traffic estimation tools, the most important step is to distinguish between search volume, estimated traffic from a single keyword, and total page traffic, and confirm the location, time period, and data coverage. Estimates are useful for comparing opportunities and observing trends, but should not be treated as records of actual website visits. When figures differ, first check whether you are comparing different metrics, then look for other keywords the page ranks for. Without website analytics data, you cannot confirm a competitor’s actual traffic.

Traffic from a single keyword is not the same as total page traffic

Consider this example: a page ranks seventh for a keyword with a monthly search volume of 260 and is estimated to receive 5 visits from that keyword. Yet the same page is reported to receive roughly 3,800 monthly visits from Google. These figures do not necessarily contradict each other:

• 260 describes search demand for that keyword, not the number of visits the page can receive.
• The estimate of 5 visits covers a single keyword, not the page’s total search traffic.
• If the 3,800 figure also comes from a third-party tool, it remains an estimate that needs checking and should not be assumed to be an actual count.

Participants in the Warrior Forum discussion suggested checking other keywords the page ranks for: a page that appears optimized for only a few keywords may still rank for other phrases. However, this is only a possible explanation to investigate, not proof that other keywords account for the difference.

First confirm metric definitions and the scope of the comparison

Semrush’s 2024 tutorial distinguishes the traffic potential of a single keyword from that of a topic. A topic’s traffic potential also includes the traffic that keyword variants with high search volumes could bring. Confusing the two can lead you to misjudge how many visitors a keyword or topic could attract.

Make sure you are comparing data for the same location, too. In a 2013 article, Semrush advised local businesses to check monthly search volume in their target area rather than rely solely on global data. This advice comes from an older article; it does not mean the tool interface described there is still current.

Google Trends, meanwhile, shows relative interest, not search counts. If two terms use different baselines, a score of 80 for each does not mean they have the same search volume.

Check against actual data rather than applying a fixed error rate

For your own website, you can use Google Search Console to check clicks for search queries and compare them with tool estimates. If competitors have not provided analytics data, acknowledge the uncertainty rather than insist that third-party figures add up perfectly.

Screaming Frog tested three tools using UK organic traffic data from 25 websites for February through April 2016, finding both overestimates and underestimates. The author explicitly described this as a quick, small-scale test, not a rigorous scientific experiment. The test therefore cannot establish which tool is most accurate today, and the errors found then cannot be used as universal correction factors.

Search demand also needs to align with business goals

A topic with a higher traffic estimate is not necessarily worth prioritizing. Before conducting an analysis, understand the product’s positioning, market, and target consumers. For example, a jewelry brand that produces large amounts of fashion styling and beauty content may attract traffic without necessarily generating sales. Rather than dwell on every estimate, first assess whether the topic is relevant to the business, then examine trends and relative changes. This helps you avoid mistaking traffic growth for business results.
