Once you have chosen the name for your site based on a low competition, high search per month basis you are ready to start building your site and optimising it for your chosen key words, The first step is to log in to your hosting cpanel accountant select the fantastico icon, once you have clicked this you will have come to a page there you can choose from a huge set of options, don`t worry, just click on the wordpress option, then open a new wordpress directory, its simple click on the new installation option, choose a name for your directory that will later appear as www.yoursite.com/example
then fill out the other few options like user name and pass word, after that click the install button, save the log in url that it gives you and go to the new wordpress admin ares, "remember log in, password and log in url." now you are ready, The site will automatically be set not to let search engines search for your site, This is fine for now,
Now go down all of the options on the left hand side of the page and set them as you see fit, ie set your author name, the site name , tag lines etc until you get to the bottom, You will come across the Themes option, this one is very important, choose a nice theme that suits your type of site,You can also choose how many posts per page to be shown etc, this is all personal preference, Just set the site up to you think it looks nice, and always set the permalinks to custom, click inside the box after you have selected the option and an autofill will appear something like %postname%, use that, That will give your posts url extensions that are relevant to the title rather that calling them p12 or whatever.
Now you are set to start righting, I would suggest that you can use plr material in your site as content as long as you do not claim it to be yours by submitting it to article directories, If you use your own original content your site will be a lot better either way, It is after all the quality of the content that will get people coming back to your site.
