Tips for scraping LinkedIn public data at scale?

Does anyone have any tips for scraping LinkedIn public profiles?

I can get all the profile URLs fine form Google but the LinkedIn auth wall triggers really quickly even with my 100% clean residential IP. Also I can beat the bot verification automatically but it seems to hardly trigger and just gives me the auth wall.

So far I've looked at

Trying to pull the profiles from search engine caches but they are all no archive tagged
Pretending to be Google with google bot user agent and google crawler IP sent in the forwarding headers
Rotating user agents/cookies etc etc

I suppose the best route would be to make 100s of profiles and use some rotating 4G proxies and scrape while logged in?

So...anyone got any tips on scraping LinkedIn?

You can use the solution you mentioned.

Or scrape Sales Nav with your research criteria to accomplish this.

The authwall isn't their to prevent scraping. It's normal LinkedIn behaviour, they show an authwall to human users too when trying to access an account through serps or direct links.

Yep.

Just as mentioned above, the authwall is pretty typical even to casual LinkedIn users following direct links and such. Interestingly, I wondered if LinkedIn was sending a cookie that they use to track the number of profile views or if there was tracking from the server-side. As far as I can tell, clearing cache doesn't really affect it so there's that.

Check out browser addons specifically for LinkedIn n reverse those addon apis or bot them.
Clever search engine dorks.. better off hitting other resources who have aggregated data vs trying to directly scrape LinkedIn

there are many chrome extensions
