If you are selling real estate, I sincerely doubt any of these visitors will be interested in your sites content. However, it's generally unacceptable to try to get traffic for keywords that are not relevant to your site. The engines are there to help people find what they are looking for. If people try to subvert the quality of the engines then the experience is spoiled for everyone. If you are looking for relevant visits that bring targeted clients, then you need to be more careful in your selection.
Relevant visits equal more chances for sales and more chances for return visits.
In this section we'll show you how to select relevant keywords. In the following sections we'll show you how to apply them. This may not make sense now, but it will pay off later. If you use plurals of your words, those who search for the singular and plural will both find your site. One word alone will get a few people, but most people search using a phrase of two or more words.
