I have never bought traffic from 7search before but quality traffic mainly comes from solo ads... from individual sellers.. those will give you more potential leads

I wuldn't rely on 7search if you want to build a big list, i feel it will be a waste of time.

I would suggest you buy solo ads for building your list. Just make sure to buy from reputable sellers. Here's what to do:
- Look for about 10 solo ad vendors with good reviews.
- Buy small packages and track your stats (clicks/conversions/sales) and add the results into an excel file.
- After some time buy a larger packages from the sellers that gave you the best results.
- Rinse and repeat and make money

It's always best to have your own data available, you'll be glad you kept that in the long run.

Good luck!

you can get traffic just by mannual way,i never buy traffic and i am getting traffic for my blog because i am giving attention just to my content.So you also use e-mail marketing just by mannual way not by buying.

Yes I would say that traffic form 7 search is good but you have to determine which niche you want the traffic from

Why are you considering 7search and what other places are you condering? If you post what kind of customer you're looking for we can give you better advice.
