Of course, not all the tips here fit all developers, but I found some of them very interesting.

  1. Integrate with a popular app
  2. Create a YouTube video
  3. Launch in an easier country
  4. Get listed in third party app stores
  5. Start sending emails
  6. Run a contest
  7. Change your colors
  8. Start a retargeting campaign
  9. A/B test your web site before conducting ASO
  10. Ask for feedback

I would say that sometimes using just one of these tips won't have a big influence on the number of app installs. But using some or all of these tips, if possible - would certainly increase your chances.
Number 3, in my eyes is the most important tip.
