domain, wp free template, use the forum backlinks service or fiverr, write articles, submit them in directories, buy more articles and post more content with the right keywords
If you are a noob and have no idea what your doing... I would research a niche you have interest in (that way you can write content and not get bored) and get cracking.
1) Buy a Domain
2) Set-up Wordpress
3) Pick a free theme
4) Write Content
5) Download Relevant Plug-ins to stream line
And just play around with your site, try small SEO tactics one at a time, look up your competition and find out what they are ranking for..You need to just experiment. No guide or no advice will help you unless you get your feet wet.
The replies in this thread are the most random I have ever seen.
Don't spend the money just because you have $200.
Use it when you really have an idea worth investing in.
I would'nt use the $180 on Google Adwords, theres so many free coupons out there that give you $75 google adwords for free and people sell them for like $3 to $5 each. It's good to test the waters, pay $5 from some guy selling the coupons and get $75 worth of advertising free.
Buy a domain, put adsense, write about content get on the top of the search engines, profit.
Before buying any domain do a thorough research in the niche, keywords, competition etc. There is nothing worse than investing money into something which gives no profit back.
