Your question is difficult to understand. What is your native language? Maybe you can repeat your question in your native language?
While I was working as an employee in a SME of the automotive industry (aftermarket - manager level) and still being "fresh" in the market, I used to tour my competitor that still didn't know me and have informal talks around their products. It's a friendly manner to get an imprint of your market quickly and see what are the point of focus of your competitors. But Keep it simple. A scam, a complicated covert story or an undue request for quotation could backfire on you. Even legally.
Hello, Thanks for your reply, How can I understand that, from where competitor getting visitors and where they placed there ads.
