Probably a good idea to do so

If you own a website or a blog then you should probably go and tag it and some posts via different places that allow you to tag websites or blogs. In addition you should also go and submit your blog or website into various directories like DMOZ and Yahoos Directory. Asking for link trades and commenting on other peoples blogs is another good way to generate traffic and making sure your blog has content that is updated constantly is another good thing.

If you accomplish all this for your blog or website then your off to a great start I can assure you of that but there is a ton of more stuff you can do to get better search results and more traffic and by doing some research anyone can launch and successful online whatever in a matter on weeks.
