The verdict
If Google Ads already works for you and you want more of the same intent, test Microsoft Advertising. Use the Google Import tool, set a modest budget and compare cost per lead after a few weeks. The audience is smaller than Google's, so it will not grow a business alone.
If you already spend on one or both networks and checking them by hand takes too long, add Adalysis. It covers both.
I would not pay for Adalysis before you have meaningful spend. And I would not expect either tool to fix poor conversion tracking, so set that up first.
