Got a call from Google today - our optimization score was too low, so was told we have to "get it back to 85% for our ads to continue to show well," and, also, to have any chance of technical support, "and so on, and so forth." Couldn't get a clear explanation what the consequences could be. I was told to go through our account recommendations and apply fixes, and they really hope we could get this done by Friday. Among the top recommendations were:1) The Customer Match feature. Upload your customers data - e-mails, phones and addresses - so they could create "audiences" on their and and target our ads better.2) Enable ad targeting using ROI - return on ad spent. So, they'd like to peak into our business performance. With a few decades in our industry I know this is usually done to improve margins, e.g. software feature licensing.There were a few other technical fixes which were logical, and we've implemented them, but I believe the Google machine will keep ploughing and our score will sink below 85% again, as others will start leaking their clients' data and commercial information.We have been with Google for many years, and we rely on Adwords in our business to a high degree. Now having this gut feeling - either I am overreacting or actually being boiled alive. What others think about this? What's your strategy to deal with the Google Optimization Score if you don't want to leak your clients' data or accounting books?
