What is the estimation (~ number based on passing) after I apply a filter to a report? Question

When applying a filter to a report in SEMrush, you may notice an estimated number of total keywords based on the filter listed above the table in the report. It will appear as a number with a tilde (~) to represent an estimation.

(~ = Estimation)

Because of the enormous size of our database, it is difficult to provide an exact number of keywords after applying a filter to a large report, so we estimate the number based on what percentage of the report’s total keywords we analyzed (or passed) to find the first 100 keywords of the filtered list.

However, the best way to find the total number of keywords after a filter is to export your results to a spreadsheet and find the last row. The amount of keywords exported to the file will be the correct number that was in our database.

Example:

In the image above, we can see that IMDB's domain has a total of 15.2 million keywords. There is a filter applied for “star wars” and SEMrush is showing keywords ranked 101-200 based on Traffic %.

In order to find these first 200 keywords including “star wars,” SEMrush had to analyze (based on passing) 0.39% of the 15.2 million keywords. When we apply this rate to the rest of the domain’s total keywords, we can estimate IMDB’s total number of keywords that include “star wars.”

The way to estimate this number is by dividing the number of results on the SEMrush interface (200 in the example above) by the percentage of keywords passed (0.39).

Or:

200/.0039 = ~51,172
