Are you tired of sending endless messages with no replies? Have you replaced your profile picture so often that strangers must think you have a thousand faces? You don't need to keep trying and failing to make a match through online dating sites. Here are seven tips to hook a hottie every time.

1. Put More Details in Your Profile
An empty lure won't draw any bites. You need to tempt the fish by offering morsels from the meat of your life, especially where they concern things like hobbies, interests, values and other indications of your personality. A detailed profile will also help the site's compatibility algorithms find you worthy matches.

2. Know Who You're Looking For
Are you interested in a long-term relationship or just a casual night of fun? Do you prefer to send flirty messages or soul-baring missives? Be specific in your search so you'll find exactly what you want. Married affairs on theaffairsite.com and other similar sites are a completely different ballgame than singles who like book clubs.

3. Take Chances
You'll never find true love if you're too scared to send that wink. When using an online dating site, it's important to be proactive and put yourself out there. You might send out a dozen messages before you get one reply, and that's okay! That's just how the Internet works. Use it to your advantage.

4. Proofread Your Messages
The occasional typo won't raise any eyebrows, but if all of your messages are filled with bad grammar and misspelled words, people are going to draw conclusions about your intelligence. On the Internet, the only way to represent yourself is with your words, to give them the time and attention they deserve.

5. Update Your Photo Library
If you aren't getting as many replies as you'd like, take a look at your profile picture. Is it small, pixelated or dimly lit? Can you see your face? Are you smiling? Profile pictures are the web equivalent of a handshake; they send a powerful first impression, one that sticks, so if you're looking grim or shadowed in your avatar, that's what other people are assuming your personality is like.

6. Show Signs of Life in Your Messages
Speaking of personality, don't be afraid to show a little spunk in your communication. For example, if you're a laid-back kind of person, you might substitute "hola" for "hello" or use a lot of emoticons. If you're generally sunny and enthusiastic, you can use exclamation points to punctuate some of your statements. These things will act as shorthand for potential matches when they're trying to figure you out.

7. Respond to All Messages
Even if the messenger don't seem like your type, it's worth the effort to send them back a short reply and see where the conversation takes you. Remember, first impressions aren't always accurate. There might be an amazing man or an incredible woman out there who just so happens to be terrible at greetings, and if you brush them off without giving them a chance, you could be missing out on your next great romance.

These are just a few things to keep in mind as you try to find the perfect match on an online dating site. Don't get discouraged if it takes you awhile to create a spark with someone; patience and perseverance is key!
