The five checks
- Title. Does it contain the phrase people search, not only your brand? Is it inside 30 characters?
- Short description. Is it a real sentence with your second most important phrases, within 80 characters?
- Rank for your top five keywords. Are they near the top? If one is at 25, move it up the list of things to fix.
- Competitor gaps. Which keyword does a close rival hold in the top 5 that you do not rank for at all?
- First two screenshots. Do they say what the app does, in a few words, without scrolling?
Then do one thing
Change one thing at a time so you can see what moved the rank. Write down the date. NextASO keeps a dated history of your listing and of your keyword ranks, so a month later you can see whether the change helped.
Set a reminder to look again in 7 to 14 days. Rank effects of a listing change rarely show on the same day.
