Keyword search volume is a measure of the number of times a given keyword or phrase is searched on a search engine, such as Google, over a given period of time. This metric is a key part of search engine optimization (SEO) and is used to help determine how competitive a keyword is in the search engine results pages (SERPs). By analyzing keyword search volume, marketers can identify what keywords are most popular and target them when optimizing their websites for better visibility. Additionally, keyword search volume can be used to inform content strategies and uncover new opportunities for growth.
