Complete your profile to 100%, including your interests.
Your profile will be more interesting and will increase the likelihood of members contacting you. Imagine if you receive a new match and their profile is empty. Would you be inclined to contact that person?
Please pay close attention to punctuation and spelling. Avoid using CAPS and "textspeak". A profile that is well written can be a strong indication of how serious you are about finding a partner.
Add up to 24 photos to your gallery.
People like photos; it's as simple as that. Make sure that your profile photo is taken in a good light and that you are clearly visible. You are 8 times more likely to be contacted if you have a profile photo.
Initiate contact with your matches.
Your matches will be flattered that you have shown interest. By initiating contact, you will increase the likelihood of getting a reply, even if it's just a smile or profile visit. You will be actively adding yourself to their 'Matches' list.
Don't be discouraged if you do not get a response. Some members don't log in every day or may not have subscribed to a Premium membership yet.
