At the moment, the search data available is so much less useful than Google Trends that there's no reason that clients would use it - they'll still just use Google trends. Best case scenario:
1) Select search data by market
2) Access historical search data
3) Google not Bing data
4) Generate related topics, related queries & top markets
Thanks Marcus, we have plans this quarter to provide more meaningful data and insights from search data.
Unfortunately Google does not have a Search API, and Historical data is currenly not available, (otherwise we'd have made this available in the first place ;-))
Cheers!
