Search suggestion is also a good way to get keywords.
Some tips for you to optimize keywords - the more keywords your app covers, you more chances it will get to be noticed and installed.

Coverage of relevant keywords and phrases is the main goal in drafting an optimized app description for Google Play. The Google Play description, or more specifically, the full description is the primary field used by Google to determine keyword rankings for an app.Be remeber to placing 8~12 keywords in app description.
You should also place the important keywords in app title, which can increase your app ranking by 10.3%.
