First, check the domain name. If the domain name doesn’t sound good, or if the domain name doesn't like a millionaire dating site, skip it. Example: Compared with hottieonly.com, MillionaireCupid.com is more likely to be a quality millionaire dating site, while the previous site is more likely to be a dating site to get beautiful ladies for sugar daddy.
Second, if you've heard of the site somewhere before, especially from the mouth of your friends, no matter how good or bad it is, the site has its reason to be existed.
Third, check the history of the website. If the site has been working for many years, it usually works better than others. Otherwise, the site will not be there anymore.
Forth, get help from google.com. Try to put the domain name in the search box, if you can find a great number of search results, the site is relatively credible.
Fifth, check the site carefully if the site will verify their users' identities. For some quality millionaire dating sites, you can surely find the verification system.
Sixth, check if the website is customer responsive. Try to send an email to support, or call the number they provided at the website. If you can get a response, the site is much better than the average.
