Yes I am also in need of an Adwords connector. There is an crucial KPI missing (well probably more...) called Search impression share. I am using alteryx to match margin to adword sales, but we also want to calcuate potential cost and revenue based on possible Search Impression share.
We're researching building connectors to both Adwords and Trends in the next quarter. However, we're interested in hearing specific use cases and what metrics you're looking for so that we can make sure what we build gets you what you need out of these platforms. Please comment or DM me with specifics.
