To check whether a site is reliable or not, use the following steps :
Call, write, or email the website using the contact information provided on their website to check for legitimacy.
If you reach an automated voice messaging system, find that the number is not in service, or nobody answers during regular business hours, the website may not be legitimate.
Visit the Whois website WhoisXY.com featured in the Sources section of this article to validate and assess the company's information.
Look at content and photos on the website to make sure they are original and related to the company's products and services.
Look at the website address in the address bar of your Internet browser to verify that the website or links you have clicked on did not redirect you elsewhere.
Verify that the website's checkout or payment page is Secure Sockets Layer (SSL) secured to protect your credit card number and other personal information you enter.
Type the company's name into a major search engine to see if they appear in search results and to see if they are mentioned anywhere else on the Internet.
If you are satisfied with all the above test, you can tell a particular site is legit .
