What will be my next spet after CL and BP

We sale our stuff of our store true CL and BP, so far we can say that dominate our category on our city on CL, we have our web page, and we are paying adwords.

I'm accepting ideas and of course if you know how to do it we are looking to pay for it. Since we sale real stuff and want to be on the market for a long time,we are thinking going north with White hat methods.

My ideas after tons of treads i read.

Web page optimization.
Search engine optimization (ad words is really expensive).
Link building to our web page.
Twitter?
Facebook?

If I post this treat on the wrong place please move it to the proper one.

thanks in advance and looking to find some savvy guys to work with.

Depending on what you are selling adwords can bring in a high ROI if you are good at PPC or hire someone who is good at it for you. It could be an expensive investment but a very profitable one (again, depends on what you are selling and your profits).

Be sure to explore web 2.0 properties such as squidoo lens. Also try youtube.

And since you have a physical business, I highly suggest you do offline marketing. Offline marketing could be easier, faster and a better investment (remember, cash isn't all you invest, your time is an investment also). Send out flyers, newspaper ads, letters, get on the radio, etc..
