Track a single anchor link in Google Analytics
<p>My client's website includes multiple product pages. On each, there is an option to "Contact Sales". This option is an anchor link that changes the screen to show the salesperson's contact information. The structure looks like this:</p>

<p>"<a href="http://www.example.com/products/detail/product-1.html" rel="nofollow noreferrer">http://www.example.com/products/detail/product-1.html</a>" is the product page.</p>

<p>"<a href="http://www.example.com/products/detail/product-1.html#contactsales" rel="nofollow noreferrer">http://www.example.com/products/detail/product-1.html#contactsales</a>" is the anchor link that makes the sales information appear. The URL doesn't change.</p>

<p>I would like to track as a conversion any time someone clicks the "Contact Sales" anchor link on any product page. I have seen some solutions that will track all anchor link clicks, but I don't want to track any anchor links other than "Contact Sales", and then only as conversions. What is the easiest way to do this? Thanks!</p>
