Situation1:

I’ve tried using the inventory.overture.com to look for bettern search words. How do i exactly go about using those keywords? do i use them in my domain title? or do i use them in my contents?

Please do more research on search engine marketing. You use keywords to market your product. You can bid on those keywords by learning how to use Adwords on Google. I recommend you get Perry Marshall’s course on how to use Adwords to drive traffic to your site. This is particularly useful if you are just starting out in Adwords advertising.

Situation2:

I’ve got myself a website before i attended your preview. it’s a package done by a internet dropshipping company. i dun hv the traffic flow to that website.

Sounds like you really need to get Perry Marshall’s course! Learn to drive traffic to your website using various means. However, there are just too many sources of traffic (at least 37 different categories online) for me to describe here, and I can only reveal them reasonably to my coaching clients.

Just bear in mind to assess your return on investment when you are planning your PPC marketing strategy. Perry’s course helps with this.
