There are two good methods that I use to find end users for my domains. One is a slightly better way than the other, but takes just a little bit more effort.
The first one is to Google the keywords in your domain. In the Google results you get, you’ll get a lot of companies with similar domain names as yours, or at least using tags with those keywords. Gather up contact emails either from Whois or from the contact info on the sites of the Advertisers in the right hand column of the Google results. These are the people that you will be sending an email to.
It’s important not to spam these people. Send an individual email to each of them, simply telling them that you have xxxxxx.com available for acquisition and you’re offering it to companies that may benefit from the domain.
Here is a sample letter that I use. It is the basics. You need to add any additional benefits that this domain would have for this company.
I am the owner of xxxxxx.com, an excellent domain name that is highly relevant to your business. I am going to list it on Sedo.com for sale, but thought I would offer it to a few select businesses that might have an interest in this domain. Since your company is in the xxx business and this domain contains keywords that are highly relevant to your company, this domain seems like a perfect match for your company.
The keywords, xxxxxxx, have approximately xxxxx searches in Google per month, and with a domain that contains these keywords exactly, it should be easy to get to page one of Google results for those keywords.
I understand that you already have a website and domain name, however this domain would be an excellent additional domain to drive highly targeted traffic to your main site. I am now taking offers on this domain before listing it on Sedo. Please contact me if you are interested in this domain.
First Name, Last Name
Adding your phone number gives you more credibility and some will call you to discuss the domain name.
The next method is pretty much the same as the first method, only this time, you Google the keywords and make a list of the competitors in the right hand column of the search results.
Then you build a quick and basic WordPress blog, and as the first post, you list all of those competitors on the page with their contact info, just like a business directory listing.
Make the title the exact same thing as the keywords. Do some social bookmarking and create some backlinks to it and within no time at all, you should be able to hit the first page of Google for those keywords. That is the goal. To get the site listed on the front page of Google.
You then contact all of the competitors listed on the site with the url of the site and show them that the site is listed on the first page of Google for those keywords. Just add that to the basic letter above.
This method works much better than the first method because they can see the listing on the first page of Google and they can see all their competitors on that site. They sure don’t want their competitors to get the site and be on the front page of Google. It gives them a great incentive to buy the domain and site.
