There are many ways to register in such directories, you can simply specify a key phrase in the search engines' registration in catalogs and released a huge amount directory where you can register your site, but look for the testimony of "particles" and pr this directory, selects themed sites that register your website, and not a few very important fact, alter the text and do not write the same titles and description for your site and use the keywords on which you want to you find potential visitors, let the title will not significantly changed, but changed. When you register, many directories are asking you to put a link back to their site. (I advise you not to do it, it affects your site). Registration in catalogs manually it does not require much time and patience, and in order that-be register a thousand directories require not one day so I advise you to use the service. You can also use the software, its the internet is more than enough.
The second method. I think that probably almost every one of internet users submit announcements on bulletin boards, on the sale or service, and to date there are very many thousands of bulletin boards, and so I think it would be foolish to exclude it as a method for plug your web site. I will not tell you how to submit announcements I think it's you know. Main publish their ads in the filed of suitable topics on your site, and do not forget to link back, Of course.
