The only way to make any type of money from a website or to get the information that you want to convey out to the world is to have visitors. Simply completing your website and getting it up and running, unless you are already a well known brand, will not do much unless you advertise. There are a number of ways to drive traffic to your website but the trick is all in the wording.
Google offers us an opportunity to create our own ads utilizing keywords that we feel others may type into the search engine. If the ad is done properly you may find your own ad either at the top or along the side of the search results page. There are many people who don't click on these ads but yet for every person that overlooks them there is going to be somebody who won't and that will translate into visitors for you.
At first it may seem that utilizing a Google ad might cost a lot of money. The truth is that you are in total control of how much your advertising will cost. You can set a daily budget or you can opt for the per click price that comes at a maximum of 10¢ per click. How you create your ad is completely up to you. Choosing the warning very carefully without overdoing the keywords is normally the best way to see success. Needless to say, this is not something that you can do, or should do, on the fly or quickly. Put a lot of thought into what you are saying and how you are creating the ad.
Once the visitor clicks on the ad, it is then up to your website to do the work to close the sale. This is why making sure that you have the most optimized site you can possibly have before going live and before advertising is extremely important. Obtaining a lot of visitors to your site is not going to do much good if you can't make the sale, unless of course, you only want to get the word out there about what you have to say. Even at 10¢ per click, you could end up spending a lot of money on advertising without seeing the sales results that you are truly looking for.
