It will be interesting to see how the launch of Google Call Metrics will affect the call tracking providers in the US. The product is currently only available in the US and not launching there until May 16. Call tracking is such a useful product to have, especially when marketing online as clients demand a choice of options when it comes to making contact. Depending on what business you are in, the telephone always remains top or near to the top when it comes to response.If you are not tracking the callers you get from PPC and other online channels, preferring to focus on web contacts, you maybe misjudging your audience. If you track your callers from this activity, you can accurately market, improving your ROI and increasing sales as a result.
