First you'll want to pick which or how many websites you want to use. If you do a search online for dating websites you'll come up with a lot. Some of the more popular websites are match.com, eharmony.com, cupid.com and plentyoffish.com. Most you subscribe to on a month to month basis but if you want to give online dating a try free the best website I can recommend is plentyoffish.com which doesn't charge a dime.
Pictures, Pictures, Pictures! You do have an option as to if you want to post your picture or not. But the majority of people are likely not to respond to an ad that doesn't have a picture posted. When you do post a picture try to post a few that have a nice face shot and a full body shot. No sleeze....guys and girls keep your shirts on....try to be professional.
If you're going to try this, at least make a decent attempt at it. Many people post their profiles but don't write anything interesting about themselves. People click on your profile but are bored quickly and move on if they don't find any info about you. Make sure to explain what you're looking for, your interests, hobbies, what makes yout tick basically. But at the same time try to keep it to the point and not type out a novel. You will need something to talk about on the first date.
Be honest! Many people tend to embelish their profiles thinking they will never meet these people offline. There is nothing more frustrating then talking to someone and then finally meeting them to realize they are 4 inches shorter and 200 lbs heavier then what they described.
Please spell check everything you write. There is no bigger turn off then reading a profile that looks like it was written by a second grader. It takes only a few minutes to spell check your profile and many websites even give you the option to do it right there as you are writing. Spelling and grammatical errors make your profile look like you are uneducated and don't care.
PLEASE don't write about how many times you have been burnt in love and how your ex is suing you for millions and won't let you see the kids. You would be amazed how many people write about their emotional baggage on their profiles. That's a huge red flag and if you do get responses they will only be from the type of people you aren't trying to attract. Everyone has issues, but please don't put them on your profile.
Almost think of this as a business resume, your not looking for a job at the local seven eleven, you are trying to find your dream job. Same thing applies for online dating, how much effort you put into your profile will effect the outcome on the types of people that are attracted to you. Be yourself and be honest and you'll probably be pleasantly surprised at the people you find yourself meeting. You never know, it could be the one.
