Provided by Google Adwords in the Google Keyword Planner tool, the search volume indicates the number of times, per month, that a keyword has been typed by users in the Google search bar.
The search volume depends on the country and the language on which our site is working. The volume for the keyword "cheap glasses" for example, will not be the same on Google.fr or on Google.ch.

SmartKeyword retrieves this data to transcribe it into its tool and gives you an additional criterion to analyze your most profitable keywords.
Keyword volume on SmartKeyword
The information on the volume of searches by keyword is available directly from 2 screens: "my keywords" and "keyword search".
Thus, you can quickly know which keywords can bring you a lot of traffic (provided you take into account the opportunity score), and other keywords that have little or no traffic and therefore are not worth working on.
My keywords screen: The search volume comes from Google Adwords from which we get the data (the positions come from our internal crawler)
Keyword research: The search volume comes from our internal database that we have purchased (the most complete in seo to date) and that allows us to do research quickly.
Inconsistencies between the volumes of the two screens can appear because the data comes from two different sources.
The Google Adwords data is updated more often because Google controls more and more the information it wants to transmit: the company shows less and less the real search volumes for some keywords in addition to aggregating the volumes between the different entries of the same keyword.
Thus, differences can appear without being very important. As long as the order of magnitude remains the same, there is no worry 😊

Some keywords have a certain seasonality, for example Valentine's Day or Halloween, that's why their volume fluctuates during the year.
Now you know everything about keyword search volume,
good job!
