A person can find out the legitimacy of a website by checking if it is Better Business Bureau accredited, verifying its certificates, reading its terms and conditions, verifying its physical or telephone contact, research on its reputation and checking if the site is secure. When doubting the legitimacy of a website, it is prudent to avoid carrying out any transactions on the site until verification is done.
The best way to verify if a website is legitimate is by checking if it is approved or listed on the Better Business Bureau website. A legitimate website is likely to have a professional appearance and well written terms and conditions. Researching across different platforms with the intention of determining the website's reputation is also a good idea.
