The ever-elusive psychographic/behavioral list. It's easy to build a demographically-defined list (location, job title, company type, etc). Not so easy to build a list that includes people with certain beliefs, or who have had certain experiences. And yet, I keep trying to figure out how to do the latter. I've had some success...

The demographically-defined list

I have always cared a lot about list quality. When I started building lists for clients, I started with the "tight & clean" approach:

This is a slow, difficult process. Over time, I came up with something better, the "refine a big, noisy list" approach:

The psychographic/behavioral list

I've got nothin shippable, just some experiments I've tried. :)

It's worth mentioning that there will be good proxies for certain behavioral characteristics. Ex: Most people who have been a manager for multiple years are likely to have had to fire one or more employees. Building a list of people with the behavioral characteristic of "has had to fire someone" isn't going to be that hard because having manager in the job title -- a demographic characteristic -- is a good proxy for the behavior we're interested in.

Phantombuster does let you scrape Facebook and LinkedIn groups. So does Apify, which I've moved to for most of my scraping work. I experimented with scraping a Facebook group once. IIRC the group was for people dealing with anxiety disorders -- a great example of a psychographic characteristic. The scrape went great. It yielded maybe around 10,000 people? Then I tried to convert that big beautiful list into email addresses and got asymptotically close to zero email addresses. If it had been a scrape of a LinkedIn group, I'm certain that closer to 50% of the list of people would have successfully converted to email addresses.

Last weekend I built a proof of concept for a prospective client. They wanted a list of companies that are likely to buy a certain kind of firm in the future. Since we don't live inside the world depicted in Minority Report, the next best alternative to find:

This resolves to a scraping job followed by an LLM filtering job.

So... the best I've been able to to come up with for building a psychographic/behavioral list:

Maybe I'm underplaying my ability to build a psychographic/behavioral list a bit. If so, it's because the inherent difficulty of this kind of list-building is greater than the difficulty of building a demographic list. But if the quality of the outreach that I'm on the receiving end of is any indicator, most people aren't even trying at all to get a relevant list. So what I consider a minimum bar for quality might be quite a bit beyond what most other outbound marketers are attempting?

Anyway, sorry for the lengthy writeup; I wanted to do a bit of a checkpoint of where I'm at with respect to list-building expertise. Maybe some of this will be helpful to others.
