I don't want to rain on your parade, but unless your "search engine" is something specialized, then I doubt it will get much play. You have to put yourself into the mind of the consumer. When they want to look for something, what do they do? Where do they turn? Its not all about just putting up a product, you have to put up something that is comparable or better than the competition, or something that is similar, but unique, and not in name only. And that's not the biggest part...
You have to SELL your idea to the customer. You have to get the name out in front of them. You have to make them aware...that's where marketing and advertising come in. For the longest time, the big search engines were Yahoo!, MSN, Lycos, AltaVista, etc. Personally, I think Lycos and AltaVista fell by the wayside. I never use them. Oh, I forgot eXcite, they fell off too. The biggest player in the last few years has been Google, and it is remarkable how they took the same concept and added a twist to it that people loved.
Ask yourself, are you ready to market your product? Do you know who your target audience is? Do you know the demographics of the customers you are trying to reach? Do you have the right amount of funding? Is your idea something revolutionary, or an improvement on something already existing? I'm glad Leroy and others are supporting you, but I feel ActivationWizard on this one. It's gonna be an uphll battle. If you have the answers to these questions, you are ready to begin your journey. But if not, I strongly suggest you get the answers or think of another venture.
