In fact, now there's nothing for free, if you have a website and still something about the commercial free promotion you can forget. Many writers have of course written in blogs, news or writing articles such as: '27 ways to unwind website free 'or' how to promote a site for 3 months recording it in catalogs and advertisements' and I actually read such articles. And so shall understand who helps free promotion and who does not, take for example a "commercial website" which offers its services on the Internet for money. How long will this promotion, and more free 'commercial site' once we can say boldly nothing, no effect, you will not get if they grow TIC or 30 or 70, but this is not enough for low-frequency words can propel you and the site, but in the top 10 your site will not fall. Many authors write blogs, news, articles, as I wrote above, for what it's all done, in fact, they do it to them on the site going down and more people there are the following begins to increase traffic. Have you ever wondered why write an article? Type: 'to promote your site for free catalogs and search engines', the man comes to read this article in the article contains references. And of course you click on these links and you delays, but such articles are very strongly attracted to, but the benefits of this, you do not get it. You begin to register your site in different services free of charge and begin to expect the same when it rises TIC. Lastly I will say only one free promotion is a myth. Good luck to you unwind, and do not forget that in any endeavor, the business must invest something to get something then.
