There Are No Backlinks, Only Metadata and Behaviour
Inside a store there is nothing to link to. Ranking is decided by how well your metadata matches the query, and then by what users do next: impression to install rate, install velocity, retention past day one and day seven, uninstall rate, crash rate, and the depth and freshness of your ratings. A listing that ranks well and converts badly will slide, because the store reads poor conversion as a poor match.
