If a customer service rep sees a customer browsing "purple vacuum cleaners", then receives a call from you asking questions about "purple vacuum cleaners", it's easy to connect the dots.
Is it legal? Sure, if you download a web page from their server, they have the right to know about it.
Thanks
Did you have to dial any codes after the phone number?
That wouldn't even be neccessary. Toll free numbers are not actual "numbers" - they just forward to an actual number. You can have eight toll free numbers going into the same base number. Big companies can have computer/phone systems that grab the inbound call, determines which "source" it came from and display that on the customer service agents screen. You likely called a number that told the CS rep you got it from the website.
For those in the states familiar with distinctive ring type services, it is along the same lines (for those who aren't, distinctive ring services allow you to have multiple phone numbers coming in on the same phone line and you know which of your phone numbers is ringing based on whether the phone does one solid ring, a double ring or a triple ring). Many home based business owners use this service to identify "how" to answer the phone (such as saying hey vs. John Doe Marketing, John speaking).
Toll free numbers are hugely cheap now a days and using seperate toll free numbers for seperate marketing efforts is but a drop in the bucket to know their conversions, etc. Think of how much companies can spend on web analytics. Toll free is a way to track offline marketing efforts. Just like we as Internet marketers want to know which search engine our visitors come from and on what keyword, they want to know which marketing efforts are producing results.
Some affiliate companies do this as well for "big affiliates" - instead of having a promo code after the main toll free number, they give them a unique toll free number that is set up in their system to "belong" to you and the computer identifies it accordingly when the calls come in.
