Hello guys! Firstly sorry for my English, it's not my native language. My idea is about online service that collect promotional materials: ad phrases, banners, slogans, etc. The sources are ad networks like adsense. Idea comes from that I require 300x250 banners, and I started to google some examples in my niche. Sure I receive some results, but it was not enough for me. I wanted to see what promo already exists and create better. The same problem I have when creating paid search adwords campaigns, landing pages, etc. I think it would be cool to collect database with promotional materials and allow user to search what they want. So what do you think about it?
