Recently, our company plans to advertise with some websites to extend our foreign trade, during these days, I had difficulty in finding the only site for advertising. I don't know if the sites which I found are legal or not. And if the advertisement can be produced the desired effect. All of these problems I have to solve. A site I fond by chance---- Alexa.com. It helps me a lot. When I googled a site, I will use this site to get some info I needed. Such as traffic rank, page views, the targeted countries and so on. I think it is very useful for me to identify a site. Because a scam site didn't have such details for searching. There are so many people in this forum met with this problem how to find a company or website is reliable. I think alexa maybe throw some light on this matter. Hope to help you.
