There’s a cool, often neglected tool you can use to find influencers…
It’s the advanced search feature in Twitter. Using Twitter’s advanced search feature, type your membership site keyword into https://twitter.com/search-advanced and take a look at the profiles that come up in the search results. Generally speaking, the number of followers the person has on Twitter is a pretty safe indicator of his or her level of influence.
Make a list of three influencers in your space. Spend some time researching the person’s products, services, followers, and their message. (Note: “influencers” may not necessarily be a single person; a company profile works just as well).
