How are you filtering great leads on LinkedIn?

Hello everyone,

I was recently suggested two automation tools for LinkedIn prospecting by @gilad_uziely (https://growth-x.com) and @veebuv (https://meetalfred.com) on Product Hunt. I could not try MeetAlfred because then need a Windows desktop for the automation and I primarily work on Linux.

I checked out Growth X and a bunch of other LinkedIn automation extensions for Google Chrome. I feel my biggest issue till now is that the core search is simply not good enough. The search is based on LinkedIn's own search which has Country and Title search plus a lot of other options like connections degree, name, etc. But what I want is detailed search inside the profile. Things like:

• Are there specific words in the person's "About"
• Have they mentioned certain words in their Experiences
• Do that have at least 3 Experience sections etc.

Basically I want to filter the best matches and send messages or requests only to them. If the search is weak, then I am simply sending too many messages/requests even with automation. Do you relate to this issue? How do you tackle it now?

Thanks in advance,
