The AI share of voice calculation formula<\/strong> measures how much of the competitive conversation your brand owns inside AI-generated answers. The most defensible baseline is:<\/p>\n

\n

AI Share of Voice (SOV) = Your brand mentions \u00f7 Total tracked brand mentions \u00d7 100<\/strong><\/p>\n<\/blockquote>\n

The formula is simple. The difficult part is defining \u201cmentions,\u201d choosing a consistent prompt set, handling recommendations and citations, and preventing one unusually long AI answer from distorting the result.<\/p>\n

What is AI share of voice?<\/h2>\n

AI share of voice is the percentage of tracked brand presence attributed to your company compared with competitors across a defined set of AI answers.<\/p>\n

For example, suppose a SaaS team runs 100 buyer prompts across ChatGPT, Perplexity, Gemini, and Claude. The answers contain:<\/p>\n

\n\n\n\n\n\n\n\n\n\n
Brand<\/th>\nMentions<\/th>\n<\/tr>\n<\/thead>\n
Brand A<\/td>\n40<\/td>\n<\/tr>\n
Brand B<\/td>\n35<\/td>\n<\/tr>\n
Brand C<\/td>\n15<\/td>\n<\/tr>\n
Brand D<\/td>\n10<\/td>\n<\/tr>\n
Total<\/strong><\/td>\n100<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Brand A\u2019s AI SOV is:<\/p>\n

40 \u00f7 (40 + 35 + 15 + 10) \u00d7 100 = 40%\n<\/code><\/pre>\n
This is a competitive, zero-sum metric<\/strong>. When one brand gains share, at least one other tracked brand loses relative share.<\/p>\n
That makes SOV different from visibility or mention rate. A brand can appear in 40% of answers while receiving only 20% of all brand mentions if many answers list several companies.<\/p>\n
The three formulas teams often confuse<\/h2>\n
Search results commonly use \u201cshare of voice\u201d to describe several related metrics. They should not be treated as interchangeable.<\/p>\n
1. Mention rate<\/h3>\n
Mention Rate = Answers containing your brand \u00f7 Total answers \u00d7 100\n<\/code><\/pre>\n
If your brand appears in 30 of 100 answers, its mention rate is 30%.<\/p>\n
Mention rate is useful for measuring coverage<\/strong>, but it is not necessarily competitive SOV. Multiple competitors can appear in the same answer, so their mention rates may add up to more than 100%.<\/p>\n
2. Competitive AI share of voice<\/h3>\n
Competitive SOV = Your brand mentions \u00f7 All tracked brand mentions \u00d7 100\n<\/code><\/pre>\n
This is the cleanest formula when the question is: \u201cHow much of the category conversation belongs to us?\u201d<\/strong><\/p>\n
It requires a fixed competitor set and a consistent counting rule.<\/p>\n
3. Citation share<\/h3>\n
Citation Share = Your cited URLs or domains \u00f7 All tracked cited URLs or domains \u00d7 100\n<\/code><\/pre>\n
Citation share measures source authority rather than brand naming. A brand may be mentioned without its website being cited. Conversely, a research report or comparison page may be cited without the brand receiving a prominent recommendation.<\/p>\n
A reliable AI visibility report should show mention rate, competitive SOV, recommendation rate, and citation share separately<\/strong>.<\/p>\n
