Know-How Exchange : Advertising/PR

A big company where?

Providing goods and services to what kind of buyers?

Magazines where?

Magazines with what kind of readership and circulation?

"my manager asked me to classified the magazines that we can make advertising on it, is there any guide to take it in my mind?" - Google display network advertising. It's inexpensive and your buyers will tell you what they're interested in and which online magazines they saw your advertisement in.

That will tell you which are the best magazines to advertise in!

Facebook advertising's pretty good for this kind of stuff too. If it's information about buyers you want (and frankly, any other information about advertising's pretty useless - and therefore expensive!)

Ask your customers and potential customers what they read. This is where you want to put your ads.

Advertise in the magazines that your target audience reads.
