SEO share of voice refers to the percentage of online visibility a website or brand has in relation to its competitors in search engine results pages (SERPs). It is a measure of how much organic traffic a website receives compared to others in the same industry or niche. This metric takes into account not only the quantity of traffic, but also the quality and relevance of the keywords and phrases that drive it. A high SEO share of voice indicates a strong online presence and a successful SEO strategy, while a low share of voice may indicate room for improvement and potential missed opportunities for visibility and traffic.
