Some advice for improving app store seo search

Remember, that listing the aso keywords, use commas only, no spaces!
Also you should not come up with the name of non-existent words. Ideally, app store optimization keywords in the name of the application must contain at least one main word. This will significantly increase the chances of an application to be found;
The most important thing in the description - the first line. Make it as informative as impossible;
Do not forget that there is a limit of 100 characters for keywords;
Use such services as appstorerankings.net, searchman.com and other similar successful app store optimization services and track competitors, but do not forget to double-check their work
