How do I get a lot of downloads of my app on the App Store? I do not have a large personal social network

Hello there! To increase Installs, definitely, you need to Promote your APPand reach top search results. Also, don’t forget to include outer-traffic sources and engage as more users, as you can. Here is some of common tips:

• Try to get lots of positive and well-written APP Reviews (with 5-star ratings!)
• Increase your Installs with incent traffic and jump higher in top rates
• Spend some time on ASO - it will help your app from different sides
• Use special services - GEO-targeted Installs, custom Reviews with Keywords

One friend of mine reached app-reviews.org, website for APP Promotionservices, and they helped him a lot with Installs,Reviews and ASO. You can try this method too - hope, that it will help! :)
