At the end of last year, I bought a domain name “ScottWhite.com”, I can see there are 19,663 people having an account with LinkedIn.
On left side, you can click on Companies to see which are the companies having Scott White term in it. The search filter of LinkedIn is really poor IMO and it will show you the results of all companies which contains not only Scott White in their company name but also shows if this name exists in their description.
Now you will see 28 companies and you can easily filter those with the number of employees by selecting employees range through Company Size filter. Find out what company names have Scott White in it and try to contact them and see if they have interest in buying that domain.
There is another tip you may use in order to find available domains to hand register and try selling to endusers.
Simply type in “Scott” in LinkedIn and select companies, it will show almost 9,000 companies which somehow has the word Scott. Now you will see Scott Kay, Scott Wilson, Scott Sports, Scott Builders and many more. Now search ScottKay.com, ScottWilson.com, ScottSports.com, ScottBuilders.com and others to see if any name is available to hand register. Do your own research, check TMs, other tools you use before buying domain and register it if you think can sell it for profit.
You can just leave the search blank and click on companies to see the result is 8,872,533. You can filter it according to your requirement and above I used Scott as an example to make things easier for you to understand.
