Here are a few ways you can use backlinks to improve your app’s ASO (app store optimization):

1. Identify high-quality websites and blogs in your app’s niche: Look for websites and blogs that cover topics related to your app, and that have a strong reputation and high domain authority. These websites are more likely to provide valuable backlinks that can benefit your app’s ASO.
2. Create valuable content: To encourage other websites and blogs to link to your app, you’ll need to create content that is informative, useful, and relevant to their audience. This could include blog posts, articles, infographics, or other types of content.
3. Reach out to website and blog owners: Once you have identified potential websites and blogs to target, reach out to the owners and ask if they would be interested in linking to your app. Be sure to explain why your app is relevant and valuable to their audience, and provide any necessary information or resources to make it easier for them to link to your app.
4. Use social media to promote your app and content: Use social media platforms such as Twitter, Facebook, and LinkedIn to promote your app and the content you have created. This can help to increase the visibility of your app and the chances that other websites and blogs will link to it.
5. Monitor and track your backlinks: Use tools such as Ahrefs or Moz to monitor and track your backlinks. This can help you to identify any opportunities for improving your backlink strategy, and to see the impact that your backlinks are having on your app’s ASO.

Overall, it’s important to focus on creating valuable content and building relationships with other websites and blogs in your app’s niche, rather than just trying to acquire as many backlinks as possible. By creating high-quality content and building genuine relationships, you can earn backlinks that will help to improve your app’s ASO and drive more traffic and downloads.
