what is your objective?

Well it depends, according Maslow Theory of Hierarchy or needs identify different needs people may want to satisfy according to their position in a society.

What this means is, some would do it for selling affliate products or clicks others would do it for just personal branding, being recognized as authority and some would do it just because they love to do it.

All of these things fulfills different kind of needs that vary from person to person, situation to situation..

For myself, I'm building a list to promote my own products...

...but I also do affiliate promotions.

I promote the products and services that I personally use, and also quality products of other Internet marketers that I know and trust.

Tip: I wouldn't recommend going into the 'solo ads' business. It's not a good long-term business model.

I've been doing email marketing for 15+ years and have looked heavily into starting a solo ad business, but it doesn't really make sense. Looks like most sell clicks for around .50 and to do that you need a customer and to do it consistently you need many customer or repeats. Compare that to promoting an offer and I make way more than .50 per click and I don't need to find a customers to pay me to do it.

What I do is heavily promote PPL (pay per lead) offers, which is basically lead generation. I do this on front-end campaigns and on the back-end I will also promote regular CPA offers as well. I just look to break-even on data acquisition costs using PPL, as there is no credit card required and all a user has to do is fill out a form for me to make money, so they typically convert at a much higher rate than offers that require a sale.

my objective is very basic, means the objective which normal to every one.
the basic thing is to become a successful businessman.
every one want growth in his life so I also want the growth in my life.

There's all this hype right now about Social Media Marketing. Social Media can send you a ton of traffic.

Don t find it hard to build a good list?

What I've been hearing over and over again is "The Money Is In The List"...

For me, my goal is to build a responsive list of email subscribers that value the emails they receive from me, enjoy being up-dated on new posts/articles written, and to whom I can market various products to, whether they be affiliate products or my own...

Not sure exactly what the number is, but I think you need to market your product around 7 times before someone will buy from you, and I guess email marketing is a great way to achieve this, if your prospects don't buy the first time they visit your site...
