The problem
On X, nonprofit is where the assumptions get expensive. X has an audience that has moved and a follower count that has not, which shapes audience size for nonprofit companies on X. On nonprofit companies on X, audience size rarely catches this: restricted funds look like revenue and cannot be spent on what you are selling. There is 1 runnable example of audience size for nonprofit companies on X below.
Doing it end to end
- Start with one of nonprofit companies on X you already know, so a wrong audience size answer is obvious rather than plausible.
- Run X Brand Presence Mapper across your list of nonprofit companies on X, which carries 1 ready made setup for audience size.
- Read ten rows of audience size on nonprofit companies on X by hand before you trust the rest of the list.
Traditional Search Tools
- The charity register, for nonprofit companies on X. Free, complete, and it carries filed accounts.
- The account's recent replies, for nonprofit companies on X. Free, and reply volume shows whether anyone is still there.
- The platform APIs. Official, accurate and gated. Most now require an app review to read a public follower count, which is weeks of work for one number.
- Social listening suites. Brandwatch, Sprout and the rest do this among many other things. Priced for a brand team, not for a qualification step in a sales list.
- SimilarWeb or a traffic estimator. A different proxy for the same question. Better for whether anyone visits, worse for whether anyone follows.
- Open the profiles. Find the accounts, read the numbers, write them down. Two minutes per brand per network, and completely accurate on the day you do it.
