It’s really hard to find people on Twitter who share your interests.
Facebook and Linkedin both have a version of the “People you may know” feature, but Twitter doesn’t. A lot of people sign up, write a tweet, then say, “Now what?”
You can find an initial group of tweeters related to your business through this specialized Google search (developed by yours truly :-):
Putting the “site:” operators in there narrows your search to only pages from twitter.com while excluding pages from the Twitter mobile site. And the “intitle:” string filters profile pages from individual tweets. This happens because Twitter puts “on Twitter” at the end of the title of every profile page:
Copy and paste site:twitter.com -site:m.twitter.com intitle:”on Twitter” keyword into your Google search bar, replace “keyword” with your own and bam! You get a list of profiles specifically related to your topic.
