Knowing the response to this question is the key to a smooth start. What do you put on your website? What add-ons are necessary to your activities? Who is your target audience? Concentrate on one subject. Creating a site that is a "hodgepodge of everything" is not useful, and confusing for site visitors and especially for search engines. You want your site visitor to know at a glance the point.
Websites have worth only if they communicate to the site visitors. And thus, your purpose should not just be to create traffic or to watch the site statistics go up this has no point. To propose a website with content that is interesting and up-to-date, the stats and the traffic take care of themselves. So the best tip is to have full rich content ! But do not copy and paste left and right, this is not allowed (and is penalised by Google).
