If your domains have a steady traffic, you should think about the proper monetization method. On the internet many services offer monetization methods that are easy to setup and to run. Most of them use either Google ads or Yahoo ads. The revenue is not very high because you have to share it with Google or Yahoo and with the monetization provider. Nevertheless it is a good alternative to developing as you neither need any knowledge about web development, nor resources like money and time.

If you have domains with steady traffic, parking would be the right monetization method for you. A big advantage of domain parking is the easy set up of parking pages. You just choose the layout and the keyword or sometimes many keywords. The rest is done by the parking company. On the other side there are some disadvantages of parking. One disadvantage is that visitors are getting use to parking pages and click away if they land on a parking site. Another disadvantage is that search engines do not like parking pages. So you will not get very high ranking, and hence not so many visitors coming from search engines.

If you want to improve the search engine ranking of your domains, but do not have the resources to develop them into websites, you should think about the parking alternatives. These are services that create websites automatically. Important is that you do not risk to be penalized by search engines because of the not unique content or other reasons. In addition to that the lay out should be visitor-friendly and of course generate revenue.

On the whole parking and parking alternatives are good ways to generate revenue without any efforts, programming knowledge and costs.
