Ever wanted to find a last name on LinkedIn without being forced to pay for an expensive upgrade? Here's how (at least, until LinkedIn discovers you can do this).
You want to know someone's last name, but they have chosen to not reveal it, so LinkedIn places the link "(Upgrade for full name)" next to the person's first name and last-name initial. DON'T BUY THE UPGRADE! Instead, copy the persons first name and initial of last name (e.g., Suzy Q.). Use Google to search for: "Suzy Q." "companyname" "linkedin". Be sure to enclose the person's name and the company name in quote marks, and don't forget to include the word "linkedin" in your search box.
In the results that Google returns, find the that has "Suzy Quartzel | LinkedIn" as the link and, in the description, it contains the person's name and the company name. Click on that link / search item and it should take you to the individual's LinkedIn profile, but this time you will see the entire name.
Note that when you first came across the name on LinkedIn, not only did it not reveal the last name in the profile, it also did not reveal the last name in the URL (makes sense, as the anonymity would be worthless otherwise.). Now look at the URL after you clicked on the link you found in Google. Voila! The URL contains the first AND last name.
Works 25% to 50% of the time.
